INTRODUCTION
This report presents the results of a subsurface soil investigation and pavement evaluation carried out
at the site of the proposed improvements to the pavements surrounding the hangars in the southwestern portion
of Chandler Municipal Airport (CHD), in Chandler, Arizona.
The purpose of this investigation was to determine the condition of the existing asphalt and subgrade
soil conditions. This data will be used to make recommendations for reconstruction, or if feasible, rehabilitation
of the apron pavements to support the anticipated traffic loads. It is understood construction will encompass
the hangar area located between Taxiway F on the south end and the west Terminal apron on the north end.
This area occupies approximately 550,000 square feet of pavement. The general project limits are shown in
Figure 1.0.1.
Figure 1.0.1 General Project Location
The scope of the field work conducted for the hangar pavement evaluation and the recommendations
presented in this report are based on the general guidelines presented in FAA AC No. 150/5320-6G. This
assessment included visual observation of the surface conditions, and a limited number of pavement
borings/cores to determine the current pavement structural sections and subgrade conditions. A review of

previous geotechnical information and reports in the vicinity of the proposed improvements was also
conducted. A Soil Boring Location Plan showing the locations of the field work (soil borings) and the
approximate limit of the project is attached in Appendix A.
Speedie & Associates (S&A) has previously completed a geotechnical report for the Terminal Apron
Rehabilitation at the airport, located to the northeast of this project (S&A Report No. 171997SA, dated April
2, 2018). The laboratory and field data obtained from the previous report was used in conjunction with the data
obtained from this current evaluation.
The Chandler Municipal Airport accommodates a variety of aircraft, generally consisting of lighter
general aviation (GA) aircraft. Typical maximum take-off weights for the larger aircraft that operate at CHD
are on the order of approximately 40,000 lbs. A higher frequency of smaller and lighter aircraft use the airport
and have access to the subject pavements. These lighter aircraft have maximum takeoff weights on the order
of approximately 3,000 to 15,000 lbs. The largest anticipated aircraft to use the pavements in this area of the
airport is likely to be the Cessna Citation XLS, with a maximum takeoff weight of approximately 20,200 lbs.
A new comprehensive traffic analysis was not conducted for the apron pavement at the time of this
report, however, the anticipated aircraft fleet mix provided by CHD is presented in Table 1.0.1. The aircraft
information provided in this table was used in combination with the findings from the geotechnical
investigation to determine the new pavement structural sections in accordance with FAA design procedures.

GENERAL SITE AND SOIL CONDITIONS
2.1
Site Conditions
The area currently consists of an asphalt paved apron area with T-hangars. The area is generally
bound to the northeast by the Terminal Apron, to the northwest by hangars followed by Airport Boulevard, to
the southeast by Taxiway A with the runway beyond, and to the southwest by Taxiway F and additional hangar
buildings. Based on general observations, there appears to be some drainage issues as there is some evidence
of water ponding adjacent to several of the hangar buildings.
A cursory review of historical aerial photographs shows that the site was previously vacant land
dating back to at least 1949, the earliest available aerial image. At that time there appears to have been either
an irrigation ditch or other drainage feature present at the west and east ends of the apron. The runway to the
east was first observed to be present around 1976. The subject apron pavement and hangar structures are first
visible in 1986. The site has remained relatively unchanged since that time.
2.2
Pavement Conditions and Measurements
Based on visual evaluation during the field investigation, the existing pavement is generally in
fair condition and showing its age. The pavement is exhibiting raveling, weathering, and a significant amount
of block style cracking. Block cracking is typical of aged asphaltic concrete pavements, especially in the dry
desert climates. These types of cracks don’t necessarily represent structural failure and are mostly attributed
to environmental factors. However, over time, as moisture infiltrates into these cracks, if not maintained, the
pavement can further deteriorate due to loss of support. This can lead to structural failure and the formation of
alligator or fatigue cracking. It doesn’t appear as though the pavement has reached this stage at this time. This
is in-part a result of the ongoing maintenance of the pavement, as it appears that efforts to maintain the
pavement have continued, including applying surface seal coats and conducting crack sealing. The quantity of
cracking has continued to progress to the point that the pavement is becoming more challenging to maintain.
Figure 2.2.1 and Figure 2.2.2 show the general condition of the pavement at the time of the investigation.
To evaluate the pavement and subgrade soils, a total of 10 borings were drilled for this
evaluation. All the borings were located within the hangar pavement area and locations were predetermined
by Dibble. The borings were placed in locations experiencing significant distress and/or where locations
ponding water was noticed after storm events. In addition, some borings were completed as close to a few T-
hangars as possible as water was noted as pooling adjacent to the hangar and potentially infiltrating underneath.
The approximate locations of the borings are shown on the Soil Boring Location Plan in Appendix A.
Thickness measurements of the existing pavement sections are summarized in Table 2.2.1 as well as on the
individual boring logs in Appendix A.

3. Where no ABC was noted, the underlying soils generally consisted of clayey sand
with gravel, which may have been a ‘dirty’ ABC.
The existing apron pavement was observed to be highly variable with the asphalt surface generally consisting
of 1.5 to 4.0 inches of asphaltic concrete. The asphalt surface layer was underlain by nil (0) to 8-inches of
aggregate base course. Where 0-inches of ABC was encountered, the material below the existing asphalt
pavement was generally granular in nature and like an aggregate base course, however based on observations
and testing, the material would not meet a typical aggregate base specification or FAA P-208/P-209
specification. This material may be suitable for reuse as subbase below any new pavement sections. Given the
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 5
age of the pavement and the findings at the core locations, variations in the pavement thicknesses to
what was observed in the specific locations should be anticipated. Based on the existing pavement section
data and the observed pavement conditions, it would appear that complete reconstruction would be necessary
if there is a desire to meet the current FAA requirements in AC 150/5320-6G. This would also provide an
opportunity to address any grading and drainage issues at the property. Alternatively, the pavement is generally
in fair condition, exhibiting primarily environmental distress and minimal load related distress. As a result, it
may be possible to conduct a rehabilitation of the pavement surface to prolong the need for full reconstruction.
2.3
General Subsurface Conditions
As indicated above, S&A obtained information about the subsurface conditions at the site using
ten 7-inch-diameter hollow-stem auger soil borings to record the soil conditions and collect samples for
laboratory testing. Possible fill or fill was encountered in several of the borings. The depth of the fill was of
variable depth ranging from 1 to 4 feet below existing grades. The fill material, where encountered, consisted
of clayey sands and clayey gravels. This material was similar in nature to that underlying native soils, making
it challenging to determine the exact depth of the fill in the small diameter bore hole. As noted above, directly
below the pavement structure there was a more granular fill material that was of similar consistency to an
ABC, however this layer typically had more fine material (and higher plasticity index) than a typical ABC.
The subsoils below any fill material generally consist of layers of sandy lean clay, clayey sand,
and silty/clayey sand with interbedded layers of sandy silt, sandy silty clay, and poorly graded sand to the
termination depths of the borings at up to 11.5 feet below existing grades. Standard penetration resistance test
(SPT) values generally ranged from 5 to 22 blows per foot and were relatively constant throughout the profile.
No groundwater was encountered during the investigation. Based on visual and tactile observation, the soils
were generally in a ‘dry to moist’ to ‘moist’ state at the time of the investigation.
Laboratory testing indicates in-situ dry densities of the upper soils range from 94.9 to 105.7 pcf
with water contents ranging from 8.9 to 21.8 percent at the time of investigation. Note, several of the moisture
content tests indicated slightly elevated values (which is not uncommon below old pavements). Several of the
moisture contents were near to above optimum moisture, based on the two moisture density (proctor) test
results. Additional discussion is provided in the following sections regarding this potential and options for
addressing elevated moisture contents below the old pavement. Liquid limits range from 22 to 40 percent with
plasticity indices from 4 to 20 percent. The upper clayey soils exhibit a volume increase (swell) due to wetting
of 2.0 to 2.6 percent when compacted to moisture and density levels normally expected during construction.

Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 6
A saturated California Bearing Ratio (CBR) test was conducted on the subgrade soils.
Saturated CBR values of 2.5 at 95 percent compaction and 4.5 at 100 percent compaction were obtained
from laboratory testing based on using a standard proctor (ASTM D698). The standard test method was
selected based on the typical aircraft loading being below 60,000 pounds, in accordance with FAA analysis
procedures. CBR values from the previous investigation ranged from 10 to 15 with a CBR value of 10 used
for that previous evaluation. However the previous CBR testing was based on a modified proctor test, which
increases the level of compaction. Therefore, it would be reasonable to assume that a CBR test using a standard
proctor would result in a slightly lower CBR value. Additional discussion on the design CBR is included in
the following section.

ANALYSIS AND RECOMMENDATIONS
3.1
Analysis
Analysis of the field and laboratory data indicates that the existing apron pavement is generally
in a fair condition and is approaching a poor condition. There is minimal evidence of load related failures in
the apron pavement, although there are low areas which appear to allow for the ponding of water after storm
events. These areas appear to be aging faster due to the moisture infiltration. The majority of the pavement
primarily appears to be experiencing normal aging and oxidation, resulting in block shrinkage cracking. Based
on the observed conditions, maintenance and rehabilitation would be an option for consideration, depending
on funding and available budget. However, as there appears to be issues related to site drainage, standing water,
and the fact that the existing pavement structure is a variable thickness and does not meet the minimum
requirements by the FAA, the primary recommendation would be to consider full reconstruction. This will
allow for the ability to make adjustments in grades and provide a suitable pavement structure that meets FAA
specifications.
A review of the Arizona Department of Transportation (ADOT) Airport Pavement Management
System (APMS) was conducted. The subject apron falls within Branch “T-HANGAR 01” and Section
“TH01CH-10”. Based on the most recent pavement condition index (PCI) survey, which was completed in
2022, the pavement has an average PCI value of 63 with the samples tested ranging from 60 to 64. This places
the pavement in a “pavement preservation” condition. Observations of the pavement from the 2022 survey
indicate a significant amount of block cracking present within the apron pavement. In addition, some
Longitudinal and Transverse Cracking (L&T Cracking) and raveling are present within this area. It appears
that from 2017 to 2022, the T-Hangar pavement area experienced no significant deterioration in the
quality of the pavement. According to the work history report, Section TH01CH-10 was constructed in 1984,
had a 1-inch Asphalt Rubber Overlay in 2006, and had crack sealing completed in 2020.

March 27, 2023 – Page 7
Based on the observations of the pavement (significant amount of shrinkage block cracking),
the average PCI value, and the fact that drainage concerns are present at the site requiring re-grading, the
primary recommendation is the pavement needs reconstruction. Once a pavement falls below the critical PCI
value (a PCI value of 55 or less), it becomes uneconomical to perform maintenance and it will be more
beneficial to reconstruct the pavement section. Any type of maintenance performed would be just done as a
stopgap to prolong the pavement until a full reconstruction can be completed. The pavement has not fallen
below the critical PCI value, however there are other factors that need to be taken into consideration when
evaluating how to proceed with a pavement rehabilitation or reconstruction. This pavement is generally
performing adequately, given the relatively thin pavement structure. There is minimal evidence of load related
failures. It appears that the majority of the distress is related to the aging process of asphalt, including oxidation,
raveling, weathering, and shrinkage cracks. Minor maintenance would still be considered an option given the
current condition of the pavement.
As noted above, the pavement structure was generally observed to be thin and variable, ranging
in thickness from 1.5 to 4.0 inches of asphalt surface placed on either a granular fill material that does not
appear to meet typical ABC specifications or up to 8-inches of ABC. The relatively thin pavement section
would not be suitable for the anticipated loading and would not meet minimum FAA requirements. If there is
a desire to meet FAA specifications or increase the frequency and loading of the aircraft on the pavement, the
relatively thin pavement structure will be insufficient. In addition, there is a need to improve the site grading
and drainage to prevent standing water and possible flooding of the hangars. Based on these findings, the
primary approach for the pavement rehabilitation will be full reconstruction to bring the pavement up
to standard and provide sufficient capacity for the current and future anticipated loading conditions.
This will also provide an opportunity to adjust any site grading and drainage.
In lieu of full reconstruction, if cost considerations are too high to fully reconstruct the
pavement section, minor improvements such as a continued maintenance using a seal coat and/or crack filling
can be completed, which will likely extend the pavement life by 2 to 5 years. Some discussion on these items
are provided in this report for reference. Due to the variable asphalt surface thickness and numerous fixed
grade points at the hangars, other rehabilitation options, such as an overlay with or without milling is likely
not feasible. If additional alternate options are desired, please contact this office for more information.
Analysis of the field and laboratory data indicates that subsoils at the site are favorable for the
support of the proposed new/reconstructed pavements subject to some remedial earthworks. For reconstruction
of the apron, the subgrade soils will be adequate for support of new pavements designed for the given airplane
traffic, subject to some remedial earthwork. Based on the observations of the pavement, the anticipated traffic
loading, and the variability in existing conditions, the primary recommendations will be to remove the existing
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 8
AC pavement section, along with sufficient subgrade material and reconstruct the apron to provide a thicker,
uniform structural section that will support the current and anticipated future loading conditions.
A soaked CBR value of 2.5 was obtained from the laboratory testing for this evaluation when
compacted to 95 percent of maximum dry density of a standard proctor (ASTM D698) and a value of 4.5 was
obtained based on a sample compacted to 100 percent of maximum dry density of a standard proctor. This
value is lower than what was determined based on a modified proctor for the Terminal Apron project to the
north. The higher level of compaction used in a modified proctor on the previous project and slightly better
soils are likely the reason for the difference. Assuming that the apron pavement will support aircraft with
maximum takeoff weights (MTOW) of less than 60,000 lbs, a standard proctor should be used in the design.
Based on these test results, the previous test results for the Terminal Apron project, our experience with the
local soil conditions, other correlations, and the recommendations provided in the FAA Airport Pavement
Design and Evaluation Advisory Circular No. 150/5320-6G, a design CBR value of 4 was assigned for
evaluation of the existing pavement structure and determination of new structural sections where required.
This value is relatively conservative given the assumption that the subgrade will not be saturated under normal
service conditions.
The soils on this site are moisture sensitive and can become unstable at elevated moisture
contents. Maintenance of the pavement is recommended as part of extending the life of the pavement and
reducing larger rehabilitation maintenance costs. Accordingly, it is highly recommended to establish a
maintenance program where crack filling and surface sealing techniques are utilized to help reduce moisture
infiltration into the subgrade and the resulting loss of support.
Groundwater is not expected to be a factor in the design or construction of new pavements and
underground utilities (if any). Excavation operations should be relatively straightforward with standard
equipment. Based on the boring and laboratory testing, and other historical information from this area, there
is a possibility for uncovering soft/moist soils beneath the existing apron pavement at depths ranging from 2±
to up to 6 feet below existing grade. In-place moisture contents were reported to be near or slightly above the
average plastic limit of 17 at the time of the investigation. This may change depending on the season work
commences and prior rainfall activity. As a result, removal and re-construction of existing apron pavement
may require additional earthwork to stabilize the subgrade soils to provide access for equipment and provide
an adequate base for new pavements. A representative of the geotechnical engineer should examine the proof
rolling prior to backfilling to ensure removal of any soft/wet soils.

3.2
Remove and Replace
As noted, based on the condition of the existing pavement and the relatively thin structural
section, the primary recommendation will be to conduct a complete reconstruction (removal and replacement)
of the pavement. Any other rehabilitation option at this point would provide little benefit and would likely
require full reconstruction within a few years. In addition, the current pavement structure is not adequate for
the anticipated aircraft loading and does not meet the minimum thickness requirements based on the current
FAA design procedures and specifications. This option will also allow for any modifications to existing
grading and drainage within the area of the apron.
Removal and replacement will require complete removal of the existing asphalt surface and
underlying subgrade/aggregate base material and replacing with a new structural section of asphaltic concrete
on new aggregate base. If grades will remain the same, the proposed new thicker structural section will require
some removal of the existing subgrade (and aggregate base (AB) where present). After removal of the surface,
the exposed subgrade will require fine grading and re-compaction in accordance with FAA P-152. The entire
area should be proof-rolled with a heavy pneumatic-tired roller to identify locally unstable areas for repair.
Deeper removal and re-compaction of the underlying subgrade is not recommended even
though it may fall below the FAA compaction requirement for new pavement. Using the lower soaked design
CBR value will compensate for this in our opinion. Excavating deeper into the subgrade may expose deeper
soft zones requiring more extensive stabilization. In addition, due to the relatively light loading, the minimum
pavement structure will likely provide excess capacity and provide additional support. The existing asphalt
may be milled to a similar consistency of an aggregate base and it, along with any aggregate base material, set
aside for possible reuse as subbase to aid in stabilizing any areas which are found to be unstable during proof-
rolling.
3.3
Seal Coat/Surface Seal
While reconstruction is the primary option at this time, as an alternative stopgap approach, the
surface could be treated using a seal coat or surface seal. A seal coat/surface seal option would help to protect
the pavement surface and would be less intrusive. However this approach does not allow for repair to any
drainage issues. If there is no need to increase the capacity of the existing pavement, this may be a suitable
option. It appears previous surface seals have been applied to the pavement previously. This will help maintain
the pavement as well as give it a uniform look. The pavement is currently performing adequately from a
structural point of view (although it may be insufficient for anticipated aircraft loading) and therefore it is
possible that just maintenance would be sufficient for the time being.
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 10
The surface is experiencing some typical signs of aging (oxidation, weathering, and block
shrinkage cracks). While the pavement section, as built, would not meet the requirements of a new FAA
pavement design, the pavement is performing sufficiently for the relatively low volume of current traffic. For
this reason, it may be possible to consider more affordable surface treatments such as a seal coat. As these
surface treatments do not typically contain an aggregate (sand only), they are not capable of spanning over
large open cracks or heavily cracked pavements. Therefore prior to conducting one of these treatments it would
be required that all heavily cracked areas and large cracks be repaired by full depth patching, crack sealing or
filling, or milling and patching in the case of large open cracks that cannot be crack sealed/filled. These
products need to be applied to a clean pavement surface or a surface treated with a with a compatible (SS-1h)
prime coat. The existing surface would need to be cleaned sufficiently removing the remnants of any old
surface treatments to ensure good performance.
If selected, the slurry seal should consist of FAA P-626 or MAG Standard Specification Section
332 Type II Slurry Seal. A slurry seal is a mixture of slow-setting asphalt emulsion, fine aggregate, mineral
filler, and water that can be used in both preventative and corrective maintenance activities. A slurry seal will
help seal surface cracks and improve skid resistance. It will also help reduce surface distress caused by
oxidation aging of the asphalt. The mixture is prepared in the form of water-based slurry and is applied in an
average thickness of 1/8 to ¼ inch. This thin surface treatment will not retard reflective cracking. Conventional
slurry seal life expectancy is on the order of 2 to 5 years.
Another more economical option to slurry seal is a proprietary micro-seal coat that contains
mineral aggregate, asphalt rubber and/or other fillers. As noted above, reflective cracking will appear through
these types of surface treatments. It is our opinion that due to the amount of cracking, a seal coat with some
aggregate and/or filler would provide adequate cover for these better areas. There are a number of different
products (such as MasterSeal MTR or MTR Plus with at least 200 pounds of aggregate per 100 gallons added
or equal product) that are available for this type of treatment and many contractors specialize in one type of
product. Therefore the final product selection will partially depend on which contractor does the repair work.
For these types of proprietary seal coats, it is recommended that the contractor provide a recommendation for
the conditions present, product specification sheets, and examples of pavements where this seal has been
applied. The owner should then visit those applications to make sure that the type of finish is acceptable. For
example thin ‘spray’ applied fog seals may not hide patches completely or it may take several applied coats if
that is the desire. In any areas where aircraft movement is sensitive to friction and braking, additional testing
may be required to ensure the surface seal does not significantly impact the friction of the pavement surface.

Crack Sealing Procedures
In order to achieve good performance for the seal coat option, it will be necessary to properly
prepare any of the cracks, including routing out the cracks to the width to depth ratio recommended by the
crack filler manufacturer. Clean the cracks by routing or using high-pressure air, sandblasting, wire brushing,
hot air blasting or high-pressure water. This is a critical step to crack sealing or filling. If the crack is not
thoroughly cleaned, the sealant will not adhere to the sides. Sand blasting, although the best for cleaning the
cracks, it is the most labor intensive. Hot air blasting is done using a hot compressed-air (HCA) lance, or heat
lance, connected to an air compressor. This method helps dry the crack and if the sealing operation closely
follows the hot air drying, the heated crack surface helps the sealant adhere to the crack. The hot air lance
produces super-heated air and will burn the crack surface if left in one place too long. If high-pressure water
is used, the crack must be thoroughly dried before sealing.
After removing the old sealant and/or cleaning the cracks, check them for depth. Generally, if
they are over 20 mm (3/4 in.) deep, a backer rod may be used to conserve sealant. The backer rod should be a
compressible, non-shrinking, non-absorbent material with a melting point higher than the sealant temperature.
The backer rod should be about 25% wider than the crack so it doesn’t slip down or float out after installing
the sealant.
Immediately before applying the sealant, inspect the cracks to ensure they are clean, dry and
any backer material is properly installed. If the cracks have been left unsealed for any amount of time, clean
them out with compressed air before sealing them. The sealant should be applied from the bottom to the top
of the crack to prevent air bubbles from forming and creating a weak spot in the sealant. It is desirable to use
a sealant kettle that has an injection wand for the best results. To prevent tracking, the sealant should be left
about 3 to 6 mm (1/8 to 1/4 in.) below the top of the crack. Use a squeegee to remove any excess sealant on
the pavement surface. For this area, it is recommended to use to Crafco Polyflex Type 3 or Type 4 or an
approved equal.
3.5
Site Preparation
The project limits are all within the existing asphalt paved apron. The entire area to be occupied
by the reconstruction option should consist of the removal of the existing asphalt pavement and additional
subgrade soils to provide room for the new pavement structural sections. Carefully remove all existing
pavements as well as any deleterious materials that may be encountered. Any existing structures and shallow
foundation elements to be removed, should be removed in their entirety along with soil disturbed by this
activity. Carefully remove all concrete and other elements as well as any deleterious materials that may be
encountered.
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 12
Special attention will need to be given to any short drilled shaft foundation removal. If any pole
or drilled shaft foundations are to be removed, the caissons are likely shallow and it may be possible to pull
the foundation out and backfill with 1-sack CLSM slurry. In the case for deeper larger caissons (if any) that
can’t be removed, they should be cut off/chipped out to a depth of at least 3 feet below finished grade or deeper
if conflict with any new foundations or utility. Do not attempt to push caissons over as that will further disturb
the soils.
The existing asphalt pavement may also be crushed/pulverized and stockpiled. If this material
is intended for reuse below the new pavement as an aggregate base in the apron area, it must meet FAA
specification for a P-208 Aggregate Base Course. Alternatively, this material could also be used to help
stabilize any soft/moist soils found below the existing apron. Enough subgrade soils should be removed as
necessary to accommodate the thickness of the new structural section. The exposed soil should be proof rolled
with a heavy rubber tire vehicle (loaded water truck or dump truck). If any utility is located within 3 feet of
any finished pavement grade, relocation of the utility may be required.
Prior to placement of fill in areas that will be subject to airplane traffic, the exposed subgrade
soils should be prepared in accordance with FAA Standard P-152. The soils should be scarified to a depth of
12 inches, moisture conditioned to optimum (3% below to 1% above) and compacted to at least 95 percent of
maximum dry density as determined by a standard proctor (ASTM D-698). The increased depth of scarification
(12 inches) will ensure that the soil compaction levels meet the requirements of FAA AC150/5370-10H.
The boring logs indicate that there are medium dense and moist soil conditions below the
existing apron pavement. A few elevated moisture contents of up to 22 percent were observed. This moisture
is over the optimum moisture based on the laboratory moisture density relations. Encountering soft wet soils
under old pavements has been an issue on other recent pavement projects at this airport. The lateral and vertical
extent of these issues can sometimes be sporadic. The reconstruction plans should assume a similar condition
and that soft/wet soils may be encountered beneath the existing pavement to depths greater than 3 feet. Trying
to accurately estimate an area that may need to be stabilized is not feasible with the current data. In addition,
these conditions can be variable depending on the season and prior rainfall activity. It is recommended that in-
situ testing be included in the construction budget and conducted as part of the site preparation phase. In-situ
testing must include means of estimating the field CBR and shear strength (such as correlations from Dynamic
Cone Penetrometer and/or vane shear testing). These will be used to evaluate the lateral extent and level of
subgrade improvement required.
If wet unstable soils are encountered, there are several options for consideration. On previous
project(s), contractors have crushed/pulverized the existing asphalt pavement and re-used the material for
subbase. If it is available from the demolition of the existing apron, it can be re-used below new pavement
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 13
sections to help stabilize and bridge the unstable subgrade. Although, depending on the crushing method,
nesting of the materials can become an issue. It will be necessary for the contractor to be able demonstrate that
there is an acceptable compaction of this material as it is not possible to complete compaction testing with a
sand cone or nuclear density gauge. The depth of removal and replacement will depend on the severity of the
problem area. It is recommended to use at least an additional 12 inches of aggregate base to replace
loose/pumping soils.
As an alternative to the re-use of crushed pavements as presented above, the unstable soils can
be completely removed to a depth on the order of 1.5 to 3 feet below the finished subgrade; deeper excavations
may be required if the loose, wet areas extend deeper. The soft/wet soils may be set aside to dry and be re-
placed and re-compacted once they have dried sufficiently. Another option is to treat the exposed unstable
subgrade with cement in general accordance with FAA P-156 using ASTM D-698 for compaction
requirements. For budgeting purposes it is recommended to use 5 percent cement mixed into the top 12 inches
of exposed subgrade them compacted per the project compaction requirements.
The clayey and silty fine sandy soils are sensitive to excessive moisture content and will become
unstable at elevated moisture content. Accordingly, it may be necessary to compact soils on the dry side of
optimum, especially in asphalt pavement areas.
3.6
Fill and Backfill
No filling or backfilling is planned for this project. Native soils are suitable for engineered
subgrade fill if required. In the event loose soft soils are encountered at the surface, the procedures as outlined
above should be followed or this office should be contacted for alternate options to stabilize. Over-excavation
of localized loose soils may use native soils as an alternative to stabilization. If imported fill is required, the
material should be granular fill meeting the following gradation and plasticity requirements.

The maximum plasticity index per ASTM D4318 should not exceed 8. A higher plasticity index
may be approved at the discretion of the engineer provided that the percent passing the No. 40 sieve and No.
200 sieve does not exceed 20 percent and 10 percent respectively.
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 14
Fill should be placed on subgrade that has been properly prepared and approved by a Soils
Engineer. Fill must be wetted and thoroughly mixed to achieve optimum moisture content, ±2 percent, be
placed in horizontal lifts of 8-inch thickness (or as dictated by compaction equipment) and be compacted to at
least 95 percent of maximum dry density per ASTM D-698 (standard proctor) for pavements supporting
aircraft less than 60,000 lbs. This includes utility trench backfill as well as general subgrade fills.
3.7
Utilities
Trench excavations for shallow utilities can be accomplished by conventional trenching
equipment. Trench walls may not stand near vertical for the short periods of time required to install shallow
utilities due to the loose soils. Sloughing may occur in looser and/or sandier soils requiring laying back of side
slopes and/or temporary shoring. Adequate precautions must be taken to protect workmen in accordance with
all current governmental regulations.
Backfill of trenches above bedding and initial backfill zones may be carried out with native
excavated (provided material greater than 3 inches is screened and removed or reduced in size). This material
should be moisture-conditioned, placed in 8-inch lifts and mechanically compacted. Water settling is not
recommended. Compaction requirements are summarized in the "Fill and Backfill" section of this report.
3.8
New Pavement
The new apron pavement will accommodate a variety of General Aviation aircraft. A
comprehensive traffic analysis was not conducted for the reconstruction of the new apron pavement; however,
we understand that the aircraft fleet mix will be as noted in Section 1.0 of this report. The pavement sections
were calculated using procedures outlined in FAA Advisory Circular AC 150/5320-6G and the FAA computer
program FAARFIELD (version 2.0.18). The designs assume that the controlling subgrade will consist of the
compacted native soils materials meeting the requirements presented herein.
Construction will require the removal of the old pavement surface in its entirety and other
existing improvements as outlined in the Site Preparation section of this report. Remove additional aggregate
base or subgrade soils to make room for the new pavement section as dictated by the selected pavement
thickness. If unstable subgrade conditions are encountered, remove and replace with one of the options
provided in Section 3.5 Site Preparation. The pavement sections provided below assume that the subgrade has
been properly prepared as set forth herein.
Geotechnical Investigation
Project No. 222006SA
Chandler Airport Hangar Area Pavement
March 27, 2023 – Page 15
It is anticipated that most of the air traffic will consist of light general aviation aircraft and
midsized business jets with typical maximum weights on the order of 3,000 to 5,000 lbs., with frequent daily
departures. In addition, there may be routine occasions where the pavement may accommodate larger aircraft,
such as the Bombardier Learjet 25 and Cessna Citation XLS with maximum take-off weights of 15,000 to
20,200 lbs. A detailed breakdown of the design aircraft fleet mix and observed number of annual operations
(provided by Dibble Engineering) is summarized in Section 1.0 of this report. For this analysis a growth rate
of 1.79 percent was applied to the aircraft traffic.
The following apron Hot Mix Asphalt (HMA) pavement sections were analyzed using the FAA
Advisory Circular 150/5320-6G Airport Pavement Design and Evaluation, assuming that the controlling
subgrade will consist of the compacted native soils materials meeting the requirements presented herein and
the FAA specifications for subgrade preparation. The capacities were determined using the guidance presented
in the Advisory Circular and with the FAA computer program FAARFIELD. A CBR value of 4 was selected
to determine the minimum flexible pavement design. This CBR value was selected based on the laboratory
testing, the soil classification, and FAA procedure for CBR selection criteria. Note, for aircraft loading less
than 60,000 lbs. it is acceptable to use FAA specification P-208 (instead of P-209), which may provide some
additional cost savings. The designer/owner should choose the appropriate sections to meet the intended use.
The following table presents alternate pavement sections, as dictated by the FAARFIELD design program:

These designs are based on materials meeting FAA Advisory Circular AC 150/5370-10H
Standards for Specifying Construction of Airports. Asphaltic concrete subject to direct plane traffic should
consist of FAA Specification P-401. A ½ inch or ¾ inch mix designation should be used for the pavement.
While a ¾ inch mix may have a somewhat rougher texture, it offers more stability and resistance to scuffing,
particularly in turning areas. The maximum aggregate size depends on installed lift thickness. Typically, the
minimum lift thickness should be at least 3.0 times the maximum aggregate size with a maximum lift thickness
of 4.0 inches. The asphalt supplier should be informed of the pavement use and be required to provide a mix
that will provide stability and be aesthetically acceptable. A mix design should be submitted for review to
determine if it will be acceptable for the intended use.
The mix design should be based for moderate aircraft using PG 70-16 asphalt oil, as this binder
is readily available and used on other state highway projects. While FAA AC 150/5370-10H generally
recommends a PG grade of lower than a -22, on the low end, due to the potential for block shrinkage cracking,
the PG70-16 is locally available and used for most paving projects. Increasing the binder range to PG70-22
will require that a polymer modified binder be used, which will result in additional construction/material costs
on the project. It is our experience that having proper compaction levels and high quality materials will help
reduce the potential for block shrinkage cracks. If budgets allows it, consideration could be given to increasing
to the binder range to PG70-22 to aid in block cracking reduction. Pavement installation should be completed
under applicable portions of FAA standards. The asphalt supplier should be informed of the pavement use and
be required to provide a mix that will provide stability and be aesthetically acceptable.

On November 15, 2022, ten (10) soil borings were drilled at the approximate locations shown on
the attached Soil Boring Location Plan. All exploration work was monitored by our Field Engineer, who
recorded subsurface conditions and obtained samples for laboratory testing. The soil borings were advanced
with a truck-mounted CME-75 drill rig utilizing 7-inch diameter hollow stem flight augers. Detailed
information regarding the borings and samples can be found on the Log of Test Boring prepared for each
drilling location.
Laboratory testing consisted of moisture content, grain-size distribution, plasticity (Atterberg
Limits) and CBR tests for classification and pavement design parameters. In-place dry density testing were
conducted on selected relatively undisturbed samples. All field and laboratory data are presented in this
appendix.

Subgrade Compaction Notes:
1. Noncohesive soils, for the purpose of determining compaction control, are those with a plasticity index (PI) less than 3.
2. Tabulated values indicate depth ranges within which densities should equal or exceed the indicated percentage of the maximum dry
density as specified in item P‐152.
3. Maximum dry density is determined using ASTM Method D 698.
4. The subgrade in cut areas should have natural densities shown or should (a) be compacted from the surface to achieve the required
densities, (b) be removed and replaced at the densities shown, or (c) when economics and grades permit, be covered with sufficient
select or subbase material so that the uncompacted subgrade is at a depth where the in‐place densities are satisfactory.
5. For swelling soils refer to AC 150/5320‐6F paragraph 3.10.
User Is responsible For checking frost protection requirements.

Subgrade Compaction Notes:
1. Noncohesive soils, for the purpose of determining compaction control, are those with a plasticity index (PI) less than 3.
2. Tabulated values indicate depth ranges within which densities should equal or exceed the indicated percentage of the maximum dry
density as specified in item P‐152.
3. Maximum dry density is determined using ASTM Method D 698.
4. The subgrade in cut areas should have natural densities shown or should (a) be compacted from the surface to achieve the required
densities, (b) be removed and replaced at the densities shown, or (c) when economics and grades permit, be covered with sufficient
select or subbase material so that the uncompacted subgrade is at a depth where the in‐place densities are satisfactory.
5. For swelling soils refer to AC 150/5320‐6F paragraph 3.10.

SECTION 1 - SCOPE OF THESE GENERAL CONDITIONS
These General Conditions encompass provisions that apply, and are incorporated into all
construction Agreements entered into by the City of Chandler, unless otherwise specifically excluded in
the executed Agreement.
SECTION 2 - GENERAL DEFINITIONS
Allowance : A specific amount for a specific item of Work, if any, that City agrees has not been sufficiently
designed, detailed, or selected (including design changes from 90% to 100% as authorized by and at
the discretion of the City) at the time the Agreement Price is agreed to for Contractor to provide a definitive
price.
Alternate Systems Evaluations or Alternative Analysis: Alternatives for design, means and methods or
other scope considerations that are evaluated using value analysis principles and have the potential to
reduce construction costs while still delivering a quality and functional Project that meets City
requirements.
Change Order: A written instrument issued after execution of the Agreement Documents signed by
City and Contractor, stating their agreement upon all of the following: the addition, deletion or revision
in the scope of services or deliverables; the amount of the adjustment to the Agreement Price, the
extent of the adjustment to the Agreement Time, or modifications of other agreement terms. The
Agreement Price and the Agreement Time may be changed only by Change Order.
Consultant: Person or firm that provides professional services.
City (Owner or OWNER): City of Chandler, a municipal corporation, with whom Contractor has entered
into the Agreement and for whom the Work or Services are to be provided pursuant to the Agreement(s).
Contingent Bid Items: This is a minor bid item which is likely, but not certain, to occur during the course
of work. If the Engineer determines that this work is required, the Contractor will accomplish the work
and payment will be made based on the contingent unit bid price included in the proposal. Since the
quantity listed in the proposal is primarily for bid comparison, the amount of work required by the
Engineer may vary materially from this.
Agreement: The written agreement executed between City and Contractor, including all of the Agreement
Documents.
Agreement Documents: The documents which together form the Agreement between City and
Contractor, as identified in Article 2 of the Agreement, or are otherwise incorporated into the
Agreement, including the Agreement, the exhibits thereto, these General Conditions, any Notice to
Proceed, and any Job Order (if applicable), the Plans and Specifications, Project Schedule, written
and properly executed Change Orders, MAG Specifications and City’s amendments thereto, and any
other documents so designated in the Agreement.
Agreement Price: The agreed-upon price to be paid to Contractor for full, timely, and acceptable
completion of the Work or Services under the terms of the Agreement.
Agreement Time(s): The number of calendar days or the dates related to the applicable phase,
Substantial Completion, or Final Acceptance as stated in Agreement Documents. Agreement Time starts
General Conditions
Revised: 7/20/22

the Agreement and is based upon the Project Schedule agreed to by City in writing.
Contractor: The person or business association with whom City has entered into an agreement for
construction related Work or Services in relation to the Project at issue.
Contractor Payment Request: The form that is accepted by City and used by Contractor in requesting
progress payments or final payment and which must include such supporting documentation as is
required by the Agreement Documents or City.

this reference. All amendments and modifications to the Construction Documents must be approved in
writing by City prior to incorporation into the Agreement.
Cost of the Work: The term Cost of the Work will mean costs necessarily incurred by Contractor in the
proper performance of the Work. Such costs will be at rates not higher than the standard paid at the
place of the Project except with prior consent of City.
Critical Path Method (CPM): A scheduling technique which identifies the logical sequence of the activities
occurring in a Construction Project, the anticipated time required to complete each activity in the
Project, and the activities that must be completed on schedule to finish the Project within the anticipated
time. Typically, activities are arranged in a network that shows both activities and their dependencies.
CPM is also used as a management technique which enables contracting parties to predict when
activities may occur so that resources can be effectively used and limitations can be identified.
Critical Path: Critical Path is the sequence of project network activities which add up to the longest overall
duration. Once established in the Project Schedule, the Critical Path for the Project must not be
changed without prior written approval of City.
Day: Calendar day(s) unless otherwise specifically stated in the Agreement Documents.
Design Professional: The qualified, licensed person, firm or corporation who furnishes design and
construction administration services required under the Agreement Documents. These services may
include, but are not limited to: development of Construction Drawings and Documents, review of
Contractor Submittal(s), review of and response
to
Requests for Information, approval and
certification of progress payment
applications,
construction administration, and construction
agreement close out.
Differing Site Conditions: Concealed or latent physical conditions or subsurface conditions at the Site
that, (i) materially differ from the conditions indicated in the Agreement Documents, or (ii) are of an
unusual nature, differing materially from the conditions ordinarily encountered and generally recognized
as inherent in the Work at the general area of the Site. Caliche, rock, hard-digging or sandy/silty soil
encountered on a project is not considered a “Differing Site Condition.”

a sufficient state of completion and released by Design Professional solely for the purposes of review
and use in performing constructability or bid-ability reviews by Contractor and in preparing cost
estimates (e.g. Master Planning and Programming, Schematic Design, Design Development, and
Construction Drawings), but “not for construction.” Shop Drawings are not Drawings as so defined.

completed, tested, and inspected in accordance with the Agreement requirements. Final Acceptance
results in a Letter of Acceptance (LOA).
Fixed Price: A fixed price or amount for an Agreement Price, Scope of Work, materials, or other item
under an Agreement, Change Order, or other agreement, which City agrees, in writing, to pay instead
of the actual cost.

The existence and number of facilities as shown on the Plans are estimated from
information furnished by the particular utility. Contractor is responsible for field verification
and location of all utilities prior to the start of construction. No field work will be allowed to
start until Contractor has contacted Arizona 811 and all affected utilities have been located.
In addition, Contractor must expose and physically locate all potentially conflicting utilities
prior to construction. The actual locations of the utilities must be compared to locations
shown on the Plans and any required changes in alignment and grade must be made at the
time of construction in consultation with Project Manager. It is generally recognized and
Contractor should anticipate that information from Arizona 811 or information from utility
companies during project design, frequently fails to disclose all underground facilities. The
fact that more utility lines or other underground facilities are located in the Project Site than
shown on the Project Plans does not constitute an “unforeseen Condition” and such
undisclosed underground facilities do not differ materially from the conditions which
Contractor should expect. The provisions of Sections 105.4, 105.6, 107.11 and 109.8.1 of the

another party is specified in the Agreement Documents) must assume full responsibility
therefor, pay all costs in connection therewith and furnish City the required certificates of
inspection, testing, or approval. Contractor must also be responsible for and must pay all
costs in connection with any inspection or testing required by the Specifications in
connection with City's acceptance of a manufacturer, fabricator, supplier or distributor of
materials or equipment proposed to be incorporated in the Work, or of materials or
equipment submitted for approval prior to Contractor's purchase thereof for incorporation
in the Work. The cost of all other inspections, tests and approvals required by the
Agreement Documents will be paid by City (unless otherwise specified).
4.4.13.3
All inspections, tests or approvals other than those required by law, ordinance, rule,
regulation, code or order of any public body having jurisdiction must be performed by
organizations acceptable to City and by the Design Professional if so specified.

furnished as part of the Work, will be new unless otherwise specified in the Agreement
Documents, of good quality, and free of defects in materials and workmanship. Contractor’s
warranty obligation excludes defects caused by abuse, alterations, or unreasonable failure
to maintain the construction by persons other than Contractor, subcontractors, or others
under Contractor’s control. Nothing in this warranty will limit any manufacturer’s warranty
which provides City with greater warranty rights than set forth herein or in the Agreement.
Contractor will provide City with all manufacturers’ warranties and operation and
maintenance manuals upon substantial completion of the Work. Contractor’s warranty
must be for one (1) year, in accordance with MAG Specification § 108.8, and will commence
for all portions of the Work upon Final Acceptance of the entire Work as determined by City
under the Agreement. All statutory or other warranties, express or implied, related to latent
defects will remain in force and are not limited by this provision.

General Conditions
Revised: 7/20/22
GC-25 of 75
Work without cost to City, or any portion thereof, until the cause for such order has been
eliminated; however, this right of City to stop the Work will not give rise to any duty on the
part of City to exercise this right for the benefit of Contractor or any other party.
4.9.3
Correction or Removal of Defective Work.
4.9.3.1
If required by City, Contractor must promptly, without cost to City and as specified by City,
either correct any defective Work, whether or not fabricated, installed or completed, or, if
the Work has been rejected by City, remove it from the Site and replace it with non-defective
Work. Contractor must correct any Work which may be displaced in correcting, removing or
replacing defective Work. No compensation will be allowed Contractor for such removal,
replacement or remedial Work. Contractor must reimburse City for costs incurred by City
due to such correction or removal including but not limited to additional expenses for
inspection, testing or observation and for repeated reviews by the City or Design
Professional.
4.9.3.2
Upon failure on the part of the Contractor to comply within a reasonably prompt time with
any written order of City to correct or remove defective Work, City has authority to cause
nonconforming materials or rejected Work to be remedied, removed, or replaced at the
Contractor's expense and to deduct the costs from any moneys due or to become due the
Contractor.
4.9.4
City May Correct Defective Work. If Contractor fails within a reasonable time after written
notice of City to proceed to correct defective Work or to remove and replace rejected Work
as required by City or if Contractor fails to perform the Work in accordance with the
Agreement Documents (including any requirements of the progress schedule), City may,
after 7 Days' written notice to Contractor, correct and remedy any such deficiency. To the
extent necessary to complete corrective and remedial action, City may exclude Contractor
from all or part of the Work, and suspend Contractor's services related thereto, take
possession of Contractor's tools, appliances, construction equipment and machinery at the
Site and incorporate in the Work all materials and equipment stored at the Site or for which
City has paid Contractor, but which are stored elsewhere. Contractor must allow City, city
representatives, agents and employees such access to the Site as may be necessary to
enable City to exercise City’s rights under this Section. All direct and indirect costs of City in
exercising such rights will be charged against Contractor in an amount verified by City
representative, and a Change Order will be issued incorporating the necessary revisions in
the Agreement Documents and a reduction in the Agreement Price. Such direct and indirect
costs will include, in particular but without limitation, compensation for additional
professional services required and all costs of repair and replacement of Work or others
destroyed or damaged by correction, removal or replacement of Contractor's defective
Work. Contractor will not be allowed an extension of the Agreement Time because of any
delay in Contractor’s performance of the Work attributable to the exercise by City or City's
rights hereunder.
4.9.5
Correction or Removal of Unauthorized Work.
4.9.5.1
Any Work done beyond the lines and grades shown on the Drawings or established by the
Design Professional or any changes in, additions to, or deductions from the Work done

at the Contractor's expense and to deduct the costs from any moneys due or to become
due the Contractor.
4.9.6
Correction Period - One Year Guarantee.
4.9.6.1
If, within one year after the date of Final Acceptance, or such longer period of time as may
be prescribed by law or by the terms of any applicable special guarantee required by the
Agreement Documents, or by any specific provision of the Agreement Documents, any Work
is found to be defective, Contractor must promptly, without cost to City and in accordance
with City's written instructions, either correct such defective Work, or, if it has been rejected
by City, remove it from the Site and replace it with non-defective Work. If Contractor does
not promptly comply with the terms of such instructions, or in an emergency where delay
would cause serious risk of loss or damage, City may have the defective Work corrected or
the rejected Work removed and replaced, and all direct and indirect costs of such removal
and replacement, including compensation for additional professional services, must be paid
by Contractor. Such action by the City will not relieve the Contractor of the guarantees
required by this Section or elsewhere in the Agreement Documents.
4.9.6.2
If, in the opinion of the City, defective Work creates a dangerous condition or requires
immediate correction or attention to prevent further loss to the City or to prevent
interruption of operation of the City, the City will attempt to give the notice required by this
Section. If the Contractor cannot be contacted or does not comply with the City's request
for correction within a reasonable time as determined by the City, the City may,
notwithstanding the provisions of this Section, proceed to make such correction or provide
such attention; and the costs of such correction or attention will be charged against the
Contractor. Such action by the City will not relieve the Contractor of the guarantees
required by this Section or elsewhere in the Agreement Documents.
4.9.6.3
This Section does not in any way limit the guarantee on any items for which a longer
guarantee is specified or on any items for which a manufacturer or supplier gives a
guarantee for a longer period. The Contractor agrees to act as co-guarantor with such
manufacturer or supplier and must furnish the City all appropriate guarantee or warranty
certificates upon completion of the Project. No guarantee period, whether provided for in
this Section or elsewhere, will in any way limit the liability of Contractor or their sureties or
insurers under the indemnity or insurance provisions of these General Conditions and the
Project Specific Special Conditions.
4.9.7
Acceptance of Defective Work.
4.9.7.1
If, instead of requiring correction or removal and replacement of defective Work, City may
accept Work when in the best interest of the City to do so with appropriate monetary credit
from Contractor. If any such acceptance occurs prior to final payment, a Change Order will
be issued incorporating the necessary revisions in the Agreement Documents, including
appropriate reduction in the Agreement Price; or, if the acceptance occurs after final
payment, an appropriate amount must be paid by Contractor to City.
4.9.7.2
Alternatively, City may require Contractor to furnish at Contractor's expense, a special
performance guarantee or other surety prior to acceptance of defective work.
4.9.8
The Warranty period begins on the Final Acceptance date noted in the Certificate of
Completion, irrespective of early completion by some Subcontractors of their work.
General Conditions
Revised: 7/20/22
GC-27 of 75
4.9.9
Contractor’s warranty obligation must be in accordance with MAG Specifications.

manufacturer’s warranty which provides City with greater warranty rights than set forth
in this Section or the Agreement Documents. Contractor must provide City with all
manufacturers’ warranties
prior to Substantial Completion, if applicable, or Final
Acceptance.
4.9.11
Contractor agrees that it will be responsible to manage and administer the correction of any
Work that is not in conformance with the Agreement Documents during the warranty
periods set forth in this Section, or during any longer periods to the extent required by the
Agreement Documents. A progress payment, or partial or entire use or occupancy of the
Project by City, will not constitute acceptance of Work not in accordance with the Agreement
Documents.
4.9.12
When notified of a warranty issue, Contractor must respond in writing within 48-hours and
must perform warranty Work as soon as material for said repairs are available (as judged
solely by City), and in any event Contractor must, take immediate steps to commence and
complete correction of nonconforming Work no later than the time period set forth in
City’s written notification in accordance with the Agreement Documents. This includes the
correction, removal or replacement of the nonconforming Work and any damage caused
to other parts of the Work affected by the nonconforming Work. If defects develop which
are determined by City to be an emergency, City will notify Contractor, via the most
expeditious means regarding the nature and condition of the defects. In turn, Contractor
must immediately dispatch necessary forces to correct the defect or the emergency
condition in accordance with Agreement Documents.
4.9.13
The time periods referenced in this Section apply only to Contractor’s obligation to
correct nonconforming Work and is not intended to constitute a period of limitations for any
other rights or remedies that City may have regarding Contractor’s other obligations under
the Agreement Documents.
4.9.14
Without limiting the foregoing or anything in these General Conditions or the Agreement
to the contrary, Contractor must obtain and provide to City all warranties for any portion
of the Project offered by the manufacturer, installer or provider thereof. City and the user
of the facility will have the right to the full value and benefit of all such warranties.
Contractor must ensure all such warranties are fully transferrable to facilitate the full value
of this Section.
4.9.15
Contractor’s warranty excludes damages or defects caused by abuse, alterations to the Work
not executed by or through Contractor, improper or insufficient maintenance, improper
operation, or normal wear and tear and normal usage.

ensuring Contractor’s general conformance with the scheduling requirements of the
Agreement Documents and completion of the Project within the Agreement Time; and (3)
monitoring and evaluating the construction status for purposes of approving monthly
progress payments. Acceptance of a submitted schedule by City should in no way be
construed as an affirmation or admission that the schedule is reasonable or workable by
Contractor. The responsibility for completing the Work on the Project within the
Agreement Time remains the obligation of Contractor. City’s review does not relieve
Contractor from compliance with the requirements of the Agreement Documents or
be construed as relieving Contractor of its complete and exclusive control over the
means, methods, sequences and techniques for executing the work.
6.2.3
The Project Schedule must show milestones, including milestones for City-furnished
information, and must include activities for City-furnished material and construction by
other contractors when those activities are interrelated with Contractor activities.

including the following:
a. Description of problem tasks, referenced to field instructions or requests
for information (RFI’s), as appropriate.
b. Current and anticipated delays including:
(i)
Cause of the delay.
(ii)
Corrective action and schedule adjustments to correct the delay.
(iii)
Known or potential impacts and their delay on other activities,

6.2.9
Critical Path Method (CPM).
6.2.9.1
Unless otherwise specified in the Agreement, the Project Schedule must include a Critical
Path
Method (CPM) diagram schedule showing the sequence of activities, the
interdependence of each activity and identifies the Critical Path.
6.2.9.2
The CPM diagram schedule must be in calendar Days and indicate duration, earliest and
latest start and finish dates for all activities, and total Float Times for all activities except
critical activities. The CPM diagram must be presented in a time scaled graphical format for
the Project as a whole.
6.2.9.3
The CPM diagram schedule must indicate all relationships between activities.
6.2.9.4
The activities making the Project Schedule must contain sufficient detail to assure that
adequate planning has been done for proper execution of the Work and such that it provides
an appropriate basis for monitoring and evaluation the progress of the Work. Individual
activities must not exceed 30 Days in length, in most cases.
6.2.9.5
The CPM diagram schedule must be based upon activities, which coincide with the Schedule
of Values.
6.2.9.6
The CPM diagram schedule must show all submittals associated with each work activity and
the review time for each submittal.

may approve Contractor’s use of Float as needed to meet Agreement Milestones and
General Conditions
Revised: 7/20/22
GC-32 of 75
the Project completion date.
6.2.10.2
Contractor will not be allowed to sequence, hide, or reallocate Float Time through
such strategies, as extending activity duration estimates to consume available Float, using
preferential logic, or using extensive crew/resource sequencing, tec. No time extensions
will be granted nor delay damages paid until a delay occurs which extends the Work beyond
the Agreement Time.
6.2.11
City-Caused Delays. City-caused delays on the Project, if any, may be offset by City-caused
time savings (i.e., Critical Path submittals returned in less time than allowed by the
Agreement, approval of substitution requests and credit changes which result in savings of
time to Contractor, etc.) In such an event, Contractor will not be entitled to receive a time
extension or delay damages until all City-caused time savings are exceeded and the
Agreement Time is also exceeded.
6.2.12
Rain-Related Delays. Contractor is required, in preparing the Project Schedule to take into
account all relevant weather conditions, including normal rainfall and distribution. No
additional compensation will be given for any rain-related delays or impacts on the Work
or the Project Schedule. No time extension will be granted in the Project Schedule unless
the rainfall during the construction of Work is unusually severe, was not reasonably
anticipated, and the total rainfall was significantly in excess of the normal rainfall for the
Project Site location. Normal rainfall for the Project will be determined from the 10-year
average rainfall for the Site as measured by the National Oceanic and Atmospheric
Administration or comparable source of reliable information for rainfall in Chandler,
Arizona. In addition, the excessive rainfall must have actually impacted Work activities on
the Critical Path and caused delay beyond any remaining Float at the time of the rain- caused
delay. The burden of documenting normal rainfall, the excessive rainfall and the impact on
Critical Path activities is on Contractor. All other provisions in the Agreement Documents
relating to claims, including without limitation notice requirements, apply to any claim by
Contractor for a rain delay.
6.2.13
City’s “Policy Statement for Calculating Delays and Damages,” Appendix 1 to these
General Conditions, will apply to all claims of delay and delay damages.
6.2.14
Force Majeure. If Contractor is delayed or prevented from the performance of any Work
required under this Agreement by reason of acts of God or other causes beyond the control
and without fault of Contractor (financial inability excepted), performance of that Work will
be excused, but only for the period of the delay. The time for performance of the Work will
be extended for a period equivalent to the period of delay. In addition, the parties agree if
Contractor’s delayed or suspended performance directly arises out of or directly results
from the COVID-19 pandemic, Contractor’s delayed or suspended performance may be
excused as set forth in this clause. Provided, however; Contractor must give the City written
notice within 30 days of the occurrence of the event giving rise to COVID-19 pandemic
related delayed or suspended performance. For COVID-19 pandemic related delay or
suspended performance, the parties must agree in writing to the length of the excused
delay or suspended performance. Further, Contractor must obtain the City’s written
approval to use any allowance established as part of the project for delays and costs related
to the COVID-19 pandemic.
6.3
SUBSTANTIAL COMPLETION
6.3.1
When Contractor considers that the Work, phase or a portion thereof, which City agrees in
General Conditions
Revised: 7/20/22
GC-33 of 75
writing to accept separately, is substantially complete, City will prepare and submit to
Contractor a comprehensive Punch List of items to be completed or corrected prior to Final
Acceptance and Final Payment. Failure to include an item on such Punch List does not alter
the responsibility of Contractor to complete all Work in accordance with the Agreement
Documents.
6.3.2
Upon receipt of Contractor’s Punch List, Project Manager will make an inspection to
determine whether the Work or designated portion thereof is substantially complete.
Project Manager may, at Project Manager’s sole option, be assisted in such inspection by
the Design Professional for the Project. If the inspection by the Project Manager discloses
any item, whether or not included on Contractor’s Punch List, which is not sufficiently
completed in accordance with the Agreement Documents so that City can occupy or utilize
the Work, phase or designated portion thereof for its intended use, Contractor must,
before issuance of the Certificate of Substantial Completion, complete or correct such
item upon notification by Project Manager. In such case, Contractor must then submit a
request for another inspection by Project Manager to determine Substantial Completion.
6.3.3
Certificate of Substantial Completion.
6.3.3.1
The Project Manager will not issue a Certificate of Substantial Completion unless and until
the Work (or separable units or Phases as provided in the Agreement Documents) is
essentially and satisfactorily complete in accordance with the Agreement Documents, such
that the Project is ready for use by City for its intended purpose, opening to the general
public, full occupancy or use by City (including, without limitation, all separate units, or
rooms, facilities, access, income-generating areas, and all areas serving the general public,
as applicable, must be ready for full-operation
without material inconvenience or
discomfort), including, to the extent applicable to the Work, the following: all materials,
equipment, systems, controls, features, facilities, accessories and similar elements are
installed in the proper manner and in operating condition, inspected and approved;
surfaces have been painted; masonry and concrete cleaned with any sealer or other finish
applied; utilities and systems connected and functioning; site work complete; permanent
heating,
ventilation, air condition, vertical transportation and other systems properly
operating with proper controls; lighting and electrical systems installed, operable and
controlled; paving completed, signage installed, and other Work as applicable, has
been performed to a similar state of essential and satisfactory completion. A minor
amount of Work, as determined by and at the discretion of the Project Manager, such
as installation of minor accessories or items, a minor amount of painting, minor
replacement of defective work, minor adjustment of controls or sound
systems, or
completion or correction of minor exterior work that cannot be completed as a result of
weather conditions, will not delay determination of Substantial Completion. If prior
written approval is obtained from City for purposes of Substantial Completion, specified
areas of the entire Work or Project may be individually certified as Substantially
Complete. In no event will Substantial Completion be deemed to have occurred unless
and until: (i) a temporary certificate of occupancy has been issued by the appropriate
Governmental Authorities (as applicable) and (ii) all terms and Work required under this
Agreement have been fulfilled by Contractor and same will have also been approved and
accepted by City, subject only to the Punch List items.
6.3.3.2
If requested by City, Contractor must complete and turn-over to City the Project on a phased
basis. Each phase will have a separate inspection by the Project Manager, a Punch List
generated, and then an inspection by City with final approval and acceptance only after the
General Conditions

Project Manager’s Punch List.
6.4
PARTIAL UTILIZATION
6.4.1
City at City’s option may use and occupy any substantially completed parts of the Work
which has specifically been identified in the Agreement Documents, or which City, the
Design Professional and Contractor agree constitutes a separately functioning and usable
part of the Work that can be used by City for its intended purpose, without significant
interference with Contractor’s performance of the remainder of the Work, provided,
however, if the portion of the Work to be used or occupied has not been found to be
substantially complete, City must do so in accordance with Section 6.3 prior to such
occupancy.
6.4.2
In lieu of the issuance of a Certificate of Substantial Completion as to part of the Work, City
may take over operation of a facility constituting part of the Work whether or not it is
substantially complete if such facility is functionally and separately usable; provided that
prior to any such takeover, City and Contractor agree in writing as to the division of
responsibilities between City and Contractor for security, operation, safety, maintenance,
correction period, heat, utilities and insurance with respect to such facility.
6.4.3
Substantial Completion of or City's beneficial occupancy of a part of the Project will not alter
the fact that the one-year warranty for the whole Project starts at the date of Final
Completion of the whole Project.
6.5
FINAL ACCEPTANCE
6.5.1
Unless otherwise expressly agreed to in writing by City, Final Acceptance must be obtained
by no later than 30 Days (60 Days for federally funded agreements) after the date of Substantial
Completion. Failure to timely obtain Final Acceptance will be a material breach of the
Agreement.
6.5.2
Upon receipt of written notice that the Work is ready for final inspection and acceptance, City
and Contractor will jointly inspect to verify that the remaining items of Work have been
completed. There will be no partial acceptance. Final Acceptance will not occur until all
items of Work, including Punch List Items, have been completed to City’s satisfaction as
reflected in the written Final Acceptance.
6.5.3
Final Payment will not be due, owing, or paid by City until Final Acceptance is issued.
6.5.4
Landscape Establishment Period. Unless otherwise expressly agreed to in writing by City, the
Landscape Establishment Period will begin on the date of Final Acceptance of the Project and
will run 90 Calendar Days thereafter. Landscape Establishment Period requirements are
detailed in General Conditions Appendices, attached herein.
6.6
CONTINUATION OF WORK
6.6.1
Permitting Contractor to continue and finish the Work or any part of it after the time fixed
for its completion (whether milestone, phase, Substantial Completion or Final Acceptance)
or after the date to which the time fixed for any completion may have been extended, does
not operate as a waiver by City of any rights under the Agreement Documents, law or equity.
6.6.2
Furthermore, the timely completion of the Work being of the utmost importance under
this Agreement, notwithstanding the existence of one or more disputes between the parties
General Conditions
Revised: 7/20/22

concerning the scope of the Work, the Project Schedule, Agreement Time, payments or any
other matter, and further notwithstanding a party’s invocation of the Dispute Resolution
provisions specified in Appendix 6 of these General Conditions, unless City suspends
the Agreement or Contractor’s performance pursuant to Section 10 of these General
Conditions, Contractor will continue to prosecute the Work, including any Change Order
work or Extra Work Orders, in a diligent and timely manner and not stop, slow down or
impede by action or inaction the progress of the Work, including commencing performance
of and thereafter completing any additional work called out in any Change Order or Extra
Work Order issued by Project Manager with the approval of City, so long as City makes
payment to Contractor in accordance with Section 8 of these General Conditions.

SECTION 9 - CHANGES TO THE AGREEMENT
9.1
FIELD ORDERS
City may authorize minor changes in the Work not involving an adjustment in the
Agreement Price or the Agreement Times, which are consistent with the overall intent of
the Agreement Documents. These may be accomplished by a written Field Order on the
standard form approved and executed by City. Such Field Orders must be binding and
Contractor must perform the change promptly. If Contractor believes that a Field Order
justifies an increase in the Agreement Price or Agreement Time, Contractor may make a
claim therefor as provided in Section 7.2.
9.2
EXTRA WORK/CHANGES IN THE WORK
9.2.1
City reserves the right to make such changes in the Plans and Specifications for the Work,
as it may deem appropriate and any such change as set forth in a written Change Order
must be deemed a part of this Agreement as if originally incorporated herein.
9.2.2
In the event City and Contractor cannot agree on the terms of a Change Order, or
when circumstances otherwise require, the Project Manager has the authority to direct the
Contractor to perform extra work, if the work in question is an item not provided for in the
General Conditions
Revised: 7/20/22
GC-41 of 75
Agreement as awarded. The Project Manager will have the authority to determine, based
upon factual evidence presented by the Contractor, whether the work in question is an
item not provided for in the Agreement as awarded. If the Project Manager directs the
Contractor to perform extra work, the Project Manager’s instructions will include a price
that the Contractor cannot exceed in charging the City for the extra work. Upon receipt of
the Project Manager’s directions to perform extra work, the Contractor must promptly
proceed with the extra work and document the actual cost thereof. Contractor’s right to
payment for extra work will be determined under Subsection 9.2.4 below. The Contractor is
responsible to manage the extra work to ensure that the price limits set by the Project
Manager are not exceeded. Contractor must perform the extra work and submit
documentation for the actual cost of the extra work to the City. A Change Order will be
issued to cover this work.
9.2.3
Contractor will not be entitled to payment for extra work unless a written Change Order, in
form and content prescribed by City, has been executed by City. On all requests for Change
Orders, Contractor must specify the increased or decreased costs and whether it
believes any extensions of time will be necessary to complete its Work as modified by the
Change Order. If extra work is performed under Subsection 9.2.2 above, a corresponding
Change Order will be prepared, approved and processed by City before payment can be
made to Contractor.
9.2.4
In general, pricing for Change Orders will include the same mark-up percentages that were
in effect when the Agreement was awarded. The cost or credit to the City resulting from a
change in the Work is subject to Appendix 1 (Policy Statement for Calculating Delays and
Damages) and will be determined, based on the type of pricing for the Agreement involved,
as follows:
a. By mutual acceptance of a lump sum properly itemized in a form acceptable
to City;
b. By unit prices stated in the Agreement Documents;
c. When the City determines that a Unit Price Book Job Order associated with
a Job Order Agreement requires a Change Order, by using the same Total
Cost Data and CCI that are in effect when the Change Order is anticipated to
be issued; or
d. By actual cost and a percentage fee covering overhead and profit, as follows:
(i)
Contractor will perform the extra work and be compensated for actual
cost of labor, materials and equipment.
(ii)
Contractor will have the right to add the fee percentage applicable
to the Work under the Agreement, or if no such fee has been agreed
to by the parties, not more than five percent (5%) to the
Subcontractor’s prices for authorized extra work performed solely
by Subcontractors. Such percentage will include all of Contractor’s
charges for overhead, profit, administration and supervision.
(iii)
Contractor or Subcontractor will have the right to add the fee
percentage applicable to Work under the Agreement for self-
performed extra work, or if no such fee has been agreed to by the
parties, Contractor’s or Subcontractor’s maximum total allowable
additions for overhead, profit, administration and supervision will

not exceed ten percent (10%) of actual verifiable labor, materials
and equipment for such self- performed extra work.
9.2.5
Any agreement which modifies the terms of the Agreement (including Change Orders)
will be approved in writing by the Project Manager. Once properly executed by both
parties, these modifications to the Agreement will have the same effect as if they had been
included in the original Agreement.
9.3
ACCURACY OF CHANGE ORDER PRICING INFORMATION
9.3.1
Subject to Sections 9.3.2 through 9.3.4, signature by the contracting parties constitutes full
accord and satisfaction between City and Contractor for all costs, damages, and expenses
of whatever kind of nature, including delay, impact or acceleration damages, which may be
occasioned by a Change Order of other modification of the Agreement agreed to in writing.
9.3.2
Accurate Change Order Pricing Information: Contractor agrees that it is responsible for
submitting accurate cost and pricing data to City to support its Fixed Price, Unit Price, or
Cost Plus Change Order Proposals or other Agreement Price adjustments under the
Agreement. Contractor further agrees to submit Change Order proposals with cost and
pricing data which is accurate, complete, current, and in accordance with the terms of
the Agreement with respect to pricing of change orders. Contractor agrees that any “buy-
out savings” on Change Orders will accrue 100% to Owner. “Buy-out savings” are defined
as any savings negotiated by the Contractor with a Subcontractor or a Material Supplier
after receiving approval of a Change Order amount that was designated to be paid to a
specific Subcontractor or Supplier for the Approved Change Order work.
9.3.3
Right to Verify Change Order Pricing Information: Contractor agrees that City, through
its designated representative, will have the right to examine, copy, and scan the records
of the Contractor, Subcontractor or Sub-Subcontractor’s records (during the Agreement
period and up to three years after final payment is made on the Agreement) to verify
the accuracy and appropriateness of the pricing data used to price all Change Order
proposals or claims. Contractor agrees that if City determines the cost and pricing data
submitted (whether approved or not) was inaccurate, incomplete, not current, or not in
compliance with the terms of the Agreement regarding pricing of Change Orders, an
appropriate Agreement Price adjustment will be made. Such post-approval Contact Price
adjustments will apply to all levels of contractors and Subcontractors and to all types of
Change Order proposals, specifically including Fixed Price, Unit Price, and Cost Plus Change
Orders.
9.3.4
Requirements for Detailed Change Order Pricing Information: Contractor agrees to
provide a detailed breakdown of allowable labor and labor burden cost (i.e., base wage
rate of applicable classifications of workers, payroll taxes, and insurance and benefits
costs). This information will be used to evaluate the potential cost of labor and labor burden
related to Change Order work. It is intended that this information represent an accurate
estimate of the Contractor’s actual labor and labor burden cost components. Information
is not intended to establish fixed billing or Change Order pricing labor rates. However, at the
time Change Orders are priced, the submitted cost data for labor rates may be used to price
Change Order work. The accuracy of any such agreed upon labor rate cost components
used to price Change Orders will be subject to later audit. Approved Change Order
amounts may be adjusted later to correct the impact of inaccurate labor cost
components if the agreed upon labor cost components are determined to be inaccurate.

or Agreement Time resulting from emergency work will be determined as provided in this
Section.
9.5
DIFFERING SITE CONDITIONS
9.5.1
If Differing Site Conditions are encountered at the Project Site, then notice by the observing
party must be given to the other party promptly before conditions are disturbed (to the extent
practicable) and in no event later than 14 Days after first observance of the conditions.
City will promptly investigate such conditions and, if City determines that Differing Site
Conditions exist and they materially cause an increase in the cost of, or time required for,
performance of any part of the Work, Contractor will be entitled to equitable adjustment
in the Agreement Price or Construction Schedule (and other time requirements), or both.
If it is determined by City that the conditions at the Project Site are not Differing Site
Conditions and no change is justified, then City will so notify Contractor in writing, stating the
reasons. Claims in opposition to such determination must be made within 14 Days after
City has given notice of its decision. If City and Contractor cannot agree on an adjustment
in the Agreement Price or Construction Schedule (and other time requirements), the
adjustment may be submitted to dispute resolution as provided these General Conditions.
9.6
CHANGES IN LAWS, REGULATIONS, OR LEGAL REQUIREMENTS OR TAXES
In the event of a material change in applicable Laws, Regulations, or Legal Requirements, or
taxes subsequent to the date of the Agreement by the parties, Contractor may be entitled
to a Change Order, in City’s discretion, to the extent Contractor can document to the
satisfaction of City that such change significantly increases Contractor’s actual cost of
performance of the Work.

failure to cure any such reasons. Upon such termination, City may: (1) take possession of
the Site and of all materials thereon owned by Contractor; or (2) finish the Work by whatever
reasonable method City may deem expedient. When City terminates the Agreement for one
of the reasons state above, Contractor will not be entitled to receive further payment until

such termination exceeds the costs and expenses of finishing the Work and any other
damages incurred by City, such excess will be paid to Contractor. If such costs, expenses
and damages exceed such unpaid balance, Contractor must pay the difference to City. This
obligation for payment will survive termination of the Agreement.
10.3

the Project prior to the termination date. Upon any termination of the Agreement, no
further payments will be due from City to Contractor.

reports
and analysis required thereunder, that Work can be properly and timely
constructed within the GMP Proposal, if accepted. CM@Risk does not assume any design
responsibilities unless specifically called for in the scope of work, but CM@Risk will be
responsible for their errors, omissions or inconsistencies included in the Work.
17.3
DETAILED PROJECT SCHEDULE
17.3.1
The fundamental purpose of the Detailed Project Schedule is to identify, coordinate and
record the tasks and activities to be performed by all of the Project Team members and
then for the Project Team to utilize that Deliverable as a basis for managing and
monitoring all member’s compliance with the schedule requirements of the Project.
Each Project Team member is responsible for its compliance with the Detailed Project
Schedule requirements. CM@Risk must, however, develop and maintain the Detailed
Project Schedule on behalf of and to be used by the Project Team based on input from the
other Project Team members. The Baseline Project Schedule must be developed as part
of the Baseline Cost Model. The Detailed Project Schedule must use the Critical Path
method (“CPM”) technique, unless required otherwise, in writing by City. CM@Risk must
use scheduling software acceptable to City to develop the Detailed Project Schedule.
The Detailed Project Schedule must be presented in graphical and tabular reports as
agreed upon by the Project Team. If Project phasing as described below is required, the
Detailed Project Schedule must indicate milestone dates for the phases once
determined. As part of construction phase, City may require CM@Risk to prepare a
“resource loaded” schedule for all work, including work performed by Subcontractors,
detailing each of the project tasks and the required/anticipated number of personnel per
day for each task. CM@Risk must also indicate on the schedule its ability to meet said
required/anticipated personnel requirements.
17.3.2
CM@Risk must include and integrate in the Detailed Project Schedule the services and
activities required of City, Design Professional and CM@Risk including all construction
phase activities based on the input received from City and the Design Professional.
The Detailed Project Schedule must define activities as determined by City to the extent
required to show: (a) the coordination between preliminary design and various pre-
construction documents, (b) any separate long-lead procurements, (c) any permitting
issues, (d) any land, right-of-way, or easement acquisition, (e) bid packaging strategy and
awards to Subcontractors and Suppliers, (f) major stages of construction, (g) start-up and
commissioning, and (h) occupancy of the completed Work by City. The Detailed Project
Schedule must include by example and not limitation, proposed activity sequences and
durations for design, procurement, construction and testing activities, milestone dates for
actions and decisions by the Project Team, preparation and processing of shop drawings

and samples, delivery of materials or equipment requiring long-lead time procurement (if
any), milestone dates for various construction phases, Total Float for all activities to the
extent authorized by City, relationships between the activities,
City’s occupancy
requirements showing portions of the Project having occupancy priority, and proposed
dates for Final Acceptance.
17.3.3
A Baseline Project Schedule must be initiated with the project Baseline Cost Model and
agreed to by the project team at the same time. CM@Risk must update and maintain a
detailed Project Schedule throughout pre-construction such that it will not require major
changes at the start of the construction phase to incorporate CM@Risk’s plan for the
performance of the construction phase Work. CM@Risk must provide updates and/or
revisions to the Detailed Project Schedule for use by the Project Team, whenever required,
but no less often than at the Project Team meetings. CM@Risk must include with such
submittals a narrative describing its analysis of the progress achieved to-date vs. the
Baseline Project Schedule, including any concerns regarding delays or potential delays, and
any recommendations regarding mitigating actions.
17.3.4
If phased construction is deemed appropriate at the time of developing the Baseline Cost
Model or during the development of the Detailed Project Schedule, and City approves,
CM@Risk must review the design and make recommendations regarding the phased
issuance of Construction Documents to facilitate phased construction of the Work, with
the objective of reducing the Project Schedule and/or Cost of the Work. CM@Risk must take
into consideration such factors as natural and practical lines of work severability,
sequencing effectiveness, access and availability constraints, total time for completion,
construction market conditions, labor and materials availability, and any other factors
pertinent to saving time and cost.
17.3.5
Long Lead Time Items. As part of developing the Detailed Project Schedule, CM@Risk must
identify all long lead time materials, fabrications, equipment, or other items which may
impact the Project Schedule and may require early action on the part of the Project Team.
Dates for selecting and ordering long lead time items will be included and highlighted
in the Detailed Project Schedule
17.3.6
Equipment Plan. Contractor must develop an Equipment Plan that addresses all rental
and owned equipment, regardless of whether such equipment will be provided by
CM@Risk or subcontractor(s), that will be necessary to construct the Project and the cost
of which will be included as a Cost of the Work in the GMP Proposal. The Equipment Plan
will seek to minimize the cost of the equipment to City and maximize the efficient and
coordinated use of the equipment for completion of the Project. The Equipment Plan will
not only include the costs and allowable lease rates for the equipment, but will also include
an equipment schedule that will be incorporated into the Detailed Project Schedule and the
Schedule of Values submitted with the GMP Proposal.
17.4
DESIGN DOCUMENT REVIEWS
17.4.1
CM@Risk must evaluate periodically the availability of labor, materials/equipment, cost-
sensitive aspects of the design; and other factors that may create an unacceptable variance
to the Baseline Cost Model and/or Baseline Project Schedule.
17.4.2
CM@Risk must recommend, in conjunction with the Project Team, those additional surface
and subsurface investigations that, in its professional opinion, are required to provide the
necessary
information for CM@Risk to construct the Project.
These additional
General Conditions
Revised: 7/20/22
GC-69 of 75
investigations, if agreed to
be necessary by the Project Manager and the Design
Professional, will be acquired by City and copies of the reports will be provided to CM@Risk.
17.4.3
CM@Risk must meet with the Project Team as required to review designs during their
development. CM@Risk must familiarize itself with the evolving documents through
pre-
construction. CM@Risk must proactively advise the Project Team and make
recommendations on factors related to construction costs, and concerns pertaining to the
feasibility and practicality
of any proposed means and methods, selected materials,
equipment and building systems, and, labor and material availability. CM@Risk must
furthermore advise the Project Team on proposed site improvements, excavation and
foundation considerations, as well as, concerns that exist with respect to coordination of
the Drawings and Specifications. CM@Risk must use established value analysis principles
in recommending cost effective alternatives.
17.4.4
CM@Risk must routinely conduct constructability and bid-ability reviews of the Drawings
and Specifications as necessary to satisfy the needs of the Project Team. The reviews must
attempt to identify all discrepancies and inconsistencies in the Construction Documents
especially those related to clarity, consistency, completeness and coordination of Work of
Subcontractors and Suppliers.
17.4.4.1
CM@Risk must evaluate whether: (a) the Drawings and Specifications are configured to
enable efficient construction; (b) design elements are standardized; (c) construction
efficiency
is
properly
considered
in
the
Drawings
and
Specifications;
(d)
module/preassembly design is prepared to facilitate fabrication, transport and installation;
(e) sequences of Work required by or inferable from the Drawings and Specifications are
practicable; (f) the design has taken into consideration efficiency issues concerning access
and entrance to the site, laydown and storage
of materials, staging of site facilities,
construction parking, and other similar pertinent issues; and (g) the design maintains
continued operation of the existing City systems and maintains traffic on adjacent
roadways. CM@Risk must also review the Drawings and Specifications to ensure that what
is depicted therein can be constructed as designed and must promptly inform the Project
Team of any issues.
17.4.4.2
CM@Risk must check cross-reference and complementary Drawings and sections within
the Specifications and in general evaluate whether: (a) the Drawings and Specifications
are sufficiently clear and detailed to minimize ambiguity and to reduce scope interpretation
discrepancies; (b) named materials and equipment are commercially available and are
performing well, or otherwise, in similar installations; (c) Specifications include alternatives
in the event a requirement cannot be met in the field; and (d) in its professional opinion, the
Project is likely to be subject to Differing Site Conditions.
17.4.4.3
The results of the reviews must be provided to Project Team in formal, written reports
clearly
identifying all reviewed documents and the discovered discrepancies and
inconsistencies in the Drawings and Specifications with notations and recommendations
made on the Drawings, Specifications and other documents. CM@Risk must meet with
Project Team to discuss any findings and review reports.
17.4.4.4
CM@Risk’s reviews must be from a Contractor’s perspective, and though it will serve to
eliminate/reduce the number of RFIs) and changes during the construction phase,
responsibility for the Drawings and Specifications will remain with the Design Professional
and not CM@Risk.
General Conditions

17.4.5
It is CM@Risk’s responsibility to assist the Design Professional in ascertaining that, in
CM@Risk’s professional opinion, the Construction Documents are in accordance with
applicable Laws, Regulations, or Legal Requirements, building codes, sound engineering
principle’s rules and regulations. If CM@Risk recognizes that portions of the Construction
Documents are at variance with applicable laws, statutes, ordinances, building codes,
sound engineering principle’s rules and regulations, it must promptly notify the Project Team
in writing, describing the apparent variance of deficiency. However, the Design Professional
is ultimately responsible for the compliance of the Drawings and Specifications with those
laws, statutes, ordinances, building codes, rules and regulations.
17.4.6
The Project Team will routinely identify and evaluate using value analysis principles and
alternate systems, approaches, design changes that have the potential to reduce Project
costs while still delivering a high quality and fully functional Project consistent with
the Project Program. If the Project Team agrees, CM@Risk in cooperation with the Design
Professional, will perform a cost/benefit analysis of the alternatives and submit such in
writing to the Project Team. City, through the Project Manager, will direct which alternatives
will be incorporated into the Project. The Design Professional will have full design
responsibility for the review and incorporation of CM@Risk suggested alternatives into
the Drawings and Specifications. CM@Risk must analyze the costs and schedule impacts of
the alternatives against the Baseline
Cost Model and Schedule and provide a
recommendation for the Project Team’s consideration and City’s approval prior to the
establishment of the GMP.
17.5
BASELINE COSTS MODEL, DETAILED COST ESTIMATES, AND SCHEDULE OF VALUES
17.5.1
At the conclusion of the Master Planning and Programming, if required, CM@Risk will
review all available information regarding the design and scope of the Project using
CM@Risk’s experience in performing similar work, knowledge of similar projects and
current and projected construction costs and, based upon that review, must develop a
Baseline Cost Model for review by the Project Team and approval by City. Once approved
by City, the Baseline Cost Model will be continually referenced as detailed estimates are
created as the design progresses throughout Pre-Construction until the final GMP for the
entire Project is established. A final GMP for the entire Project must be established and
approved by City prior to the start of construction. It is the responsibility of CM@Risk
to ensure City has sufficient information to evaluate and approve a final GMP prior to
the time necessary to start construction so construction can be completed within the
Agreement Time. The Project Detailed Cost Estimate will be the best representation from
CM@Risk of what the complete functional Project’s construction costs will be as indicated
by the most current available documents and will be constantly checked against the
Baseline Cost Model. CM@Risk must communicate to the Project Team and assumptions
made in preparing the Baseline Cost Model. The Baseline Cost
Model must support
CM@Risk’s Detailed Cost Estimates and may be broken down initially as dictated by the
available information, as required by City.
17.5.2
After receipt of the Design Professional’s most current documents from certain specified
pre- construction milestones, CM@Risk must provide a draft Detailed Cost Estimate
including a detailed written report detailing any variances to the Baseline Cost Model and
Baseline Project Schedule. The Design Professional and CM@Risk will reconcile any
disagreements on the estimate to arrive at an agreed upon Detailed Cost Estimate for the
construction costs based on the scope of the Project through that specified pre-
construction milestone. Pre-Construction milestones applicable to this paragraph are:
General Conditions
Revised: 7/20/22
GC-71 of 75
Master Planning and Programming, Schematic Design, 50% Design Development, 100%
Design Development, and 50% Construction Drawings, If no consensus is reached, City will
make the final determination. If the Project Team requires additional updates of the
Detailed Cost Estimate beyond that specified in this paragraph, CM@Risk must provide the
requested information in a timely manner.
17.5.3
If at any point the Detailed Cost Estimate submitted to City exceeds the previously
accepted Baseline Cost Model or previously approved Detailed Cost Estimate agreed to as
set forth in Section 17.5.2 above, CM@Risk must make appropriate recommendations to
project Team on means/methods, materials, and or other design elements that it
believes will reduce the estimated construction costs, such that it is equal to or less than
the established Project Team’s Baseline Cost Model.
17.5.4
Unless other levels of completion are agreed to in writing in the Construction Documents,
at 50% Construction Drawings and included with the associated report, CM@Risk must
also submit to the Project Team for review and approval a Schedule of Values that complies
with the following requirements. The Schedule of Values must be based on City standard
bid schedule and highlight significant variances from any previously submitted Schedule
of Values. The Schedule of Values must be directly related to the breakdowns reflected in
the Detailed Project Schedule and CM@Risk’s Detailed Cost Estimate. In addition, the
Schedule of Values must: (a) detail unit prices and quantity take-offs, (b) detail all other
contingencies and unit price Work shown and specified in the detailed design documents.
17.5.5
CM@Risk is to track, estimate/price and address the Project Team’s overall project cost issues
that arise outside of the Baseline Cost Model and the latest approved Detailed Cost
Estimate such as: City generated changes, Project Team proposed changes, alternate
system analysis, constructability items and value engineering analysis. The system used
to implement this process will be referred to as the Design Evolution Log. This is to be
addressed between the Baseline Cost Model and the Master Planning and Programming
Detailed Cost Estimate, and then (unless other levels of completion are agreed to in writing
in the Construction Documents) between the Detailed Cost Estimates for each of the pre-
construction milestones thereafter, Schematic Design, 50% Design Development, 100%
Design Development, and 50% Construction Documents, and the bid packages for all
Phases.
17.5.6
Upon request by City, CM@Risk must submit to City a cash flow projection for the Project
based on the current updated/revised Detailed Project Schedule and the anticipated level of
payments for CM@Risk during the design and construction phases. In addition, if requested
by City and based on information provided by City, CM@Risk must prepare a cash flow
projection for the entire Project based on historical records for similar types of projects
to assist City in the financing process.
17.5.7
Construction Water. CM@Risk must estimate the quantity of water to be used and include
the cost thereof in each Detailed Cost Estimate and GMP Proposal provided by City.
17.6
SUBCONTRACTOR AND MAJOR SUPPLIER SELECTIONS
17.6.1
There are two ways to select Subcontractors and major Suppliers prior to submission of a
GMP Proposal: (1) qualifications-based selection; or (2) a combination of qualifications
and price. Except as noted below, the selection of Subcontractors/Suppliers is the sole
responsibility of CM@Risk. In any case, CM@Risk is solely responsible for the performance
of the selected Subcontractors/Suppliers, and for compliance with the requirements of

approval by City and solicit bids for the various Work categories. If there are not three
qualified Subcontractors/Suppliers available for a specific trade or there are extenuating
circumstances warranting such, CM@Risk may request approval by City to submit less
than three names. Without prior written notice to City, no change in the recommended
Subcontractors/Supplies will be allowed.
17.6.3.2
If City objects to any nominated Subcontractor/Supplier or to any self-performed Work for
good
reason, CM@Risk must nominate a substitute Subcontractor/Supplier that is
acceptable to City.
17.6.3.3
CM@Risk must distribute Drawings and Specifications, and when appropriate, conduct a
Pre- Bid Conference with prospective Subcontractors and Suppliers.
17.6.3.4
If CM@Risk desires to self-perform certain portions of the Work, it must request to be one of
the approved Subcontractor bidders for those specific bid packages. CM@Risk’s bid will
be evaluated in accordance with the process identified below. If events warrant and City
concurs that it is necessary in order to ensure compliance with the Project Schedule
and/or the most recent Detailed Cost Estimate, CM@Risk may be authorized to self-
perform Work without bidding or rebidding the Work. When CM@Risk self-performs work
without bidding, only the actual costs associated with performing the Work in accordance
with the approved GMP will be billed and may be subject to audit by City.
17.6.3.5
CM@Risk must receive, open, record and evaluate the bids; provided, however, that if
CM@Risk or one of its affiliates is bidding to self-perform the Work that is the subject of the
bid, then the bids must be received, opened, recorded and evaluated by Project Manager
General Conditions
Revised: 7/20/22
GC-73 of 75
instead of CM@Risk. Bids for each category of Work must be opened and recorded at a
pre-determined time. The apparent low bidders must be interviewed to determine the
responsiveness of their proposals. In evaluating the responsiveness of bid proposals
CM@Risk, in addition to bid price, may consider the following factors: past performance
on similar projects, qualifications and
experience of personnel assigned, quality
management plan, approach or understanding of the
Work to be performed, and
performance
schedule
to
complete
the
Work.
The
final
evaluation
of
Subcontractor/Supplier bids must be done with Project Manager in attendance to observe
and witness the process. CM@Risk must resolve any Subcontractor/Supplier bid withdrawal,
protest or disqualification in connection with the award at no increase in the Cost of Work.
17.6.4
CM@Risk will be required to prepare two different reports on the subcontracting process.
17.6.4.1
Within fifteen days after each major Subcontractor/Supplier bid opening process;
CM@Risk must prepare a report for City’s review and approval identifying the
recommended Subcontractors/Supplier for each category of Work. The report must detail:
(a) the name of the recommended Subcontractor/Supplier and the amount of the
Subcontractor/Supplier bid for each sub-agreement; (b) the sum of all recommended
Subcontractor/Supplier bids received; (c) and trade work and its cost that CM@Risk intends
to self-perform, if any.
17.6.4.2
Upon completion of the Subcontractor/Supplier bidding process, CM@Risk must submit
a summary report to City of the entire Subcontractor/Supplier selection process. The report
must indicate, by bid process, all Subcontractors/Suppliers contacted to determine
interest, the Subcontractors/Suppliers solicited, the bids received and costs negotiated,
and the recommended Subcontractors/Suppliers for each category of Work.
17.6.5
The approved Subcontractors/Suppliers will provide a Schedule of Values with their bid
proposals, which will be used to create the overall Project Schedule of Values.
17.6.6
If after receipt of sub-bids or after award to Subcontractors and Suppliers, City objects to
any nominated Subcontractor/Supplier or to any self-performed Work without any
reasonable basis, CM@Risk must nominate a substitute Subcontractor or Supplier,
preferably if such option is still available, from those who submitted Subcontractor bids
for the Work affected. Once such substitute Subcontractors and Suppliers are consented
to by City, CM@Risk’s proposed GMP for the Work or portion thereof must be
correspondingly adjusted to reflect any higher or lower costs form any such substitution.
17.7
GMP PROPOSAL
17.7.1
When a GMP Proposal is submitted for a phase of the Work, the GMP will have a Detailed Cost
Estimate of the Costs of the Work (as set forth in Section 15.2) in each phase of the Work
that is being proposed plus the current estimate for all other Work. City will not approve
the GMP for the phase of work without a total estimate for the complete Project. City may
request a GMP Proposal for all or any portion of the Project and at any time during pre-
construction. Any GMP Proposals submitted by CM@Risk must be based on and consistent
with Baseline Cost Model and the current update/revised Detailed Cost Estimate at the
time of the request and include any clarifications or assumptions upon which the GMP
Proposal(s) are based.
17.7.2
A GMP Proposal for the entire Project will be the sum of the Cost of the Work, CM@Risk Fee,
and General Conditions Cost. CM@Risk guarantees to complete the Project at or less than
General Conditions
Revised: 7/20/22
GC-74 of 75
the final GMP Proposal amount plus approved Change Orders. CM@Risk will be responsible
for any costs for expenses that would cause the Cost of the Work actually incurred,
including the Construction Fee and General Conditions Costs, to exceed the GMP.
17.7.3
CM@Risk must prepare its GMP Proposal in accordance with City’s request for GMP Proposal
requirements based on the most current completed Drawings and Specifications at that
time, which unless otherwise directed by City in writing, will be at 100% Construction
Drawings. CM@Risk must mark the face of each document of each set upon which its GMP
Proposal is based.
These documents must be identified as the GMP Plans and
Specifications. CM@Risk must send one set of those documents to the Project Manager,
keep one set and return the third set to the Design Professional.
17.7.4
An updated/revised Detailed Project Schedule, Equipment Plan, and Schedule of Values
must be included in any GMP Proposal(s), all of which must reflect the GMP Plans and
Specifications the Detailed Project Schedule must be shown in relationship to the Project
Schedule and identify any variance to the Baseline Project Schedule. Any such Detailed
Project Schedule updates/revisions must continue to comply with the requirements of
Section 17.3.1 through 17.3.5.
17.7.5
GMP Proposals(s) Review and Approval
17.7.5.1
CM@Risk must meet with the Project Team to review the GMP Proposal(s) and the written
statement of its basis. In the event the Project Team discovers inconsistencies or
inaccuracies
in the information presented, CM@Risk must make adjustments as
necessary to the GMP Proposal.
17.7.5.2
If during the review and negotiation of GMP Proposals design changes are required, City
may authorize and cause the Design Professional to revise the GMP Plans and Specifications
to the extent necessary to reflect the agreed-upon assumptions and clarifications contained
in the final approved GMP Proposal. Such revised GMP Plans and Specification will be
furnished to CM@Risk. CM@Risk must promptly notify the Project Team in writing if any
such revised
GMP Plans and Specifications are inconsistent with the agreed upon
assumptions and clarifications.
17.7.6
All portions of or items comprising the GMP Proposal are subject to audit by City, as
deemed appropriate by City, including, without limitation, any based upon unit prices or
Work to be self- performed by CM@Risk, or its affiliates.
17.8
PAYMENT PROCEDURE FOR PRE-CONSTRUCTION SERVICES
17.8.1
Requests for monthly payments by CM@Risk for Pre-Construction Services must be
submitted monthly and must be accompanied by a progress report, detailed invoices
and receipts, if applicable. Any requests for payment must include, as a minimum, a
narrative description of the tasks accomplished during the billing period, a listing of any
Deliverables submitted, and copies of any Subconsultants’ requests for payment, plus
similar narrative and listings of Deliverables associated with their Work. Payment for
services negotiated as a lump sum will be made in accordance with the percentage of work
completed during the preceding month.
17.8.2
In no event will City pay more than seventy-five (75%) of the Agreement Price until
acceptance of ALL Pre-Construction Services and award of the final approved Construction
Services Agreement for the entire Project by City Council. If CM@Risk does not prepare a
General Conditions
Revised: 7/20/22
GC-75 of 75
GMP Proposal that is acceptable to City, or the GMP Proposal exceeds the City’s
Construction Budget, then CM@Risk understands and acknowledges that it will forfeit any
right to receive the 25% of the Agreement Price being retained by City.
17.8.3
CM@Risk agrees that no charges or claims for costs or damages of any type will be made by
it for any delays or hindrances beyond the reasonable control of City during the progress of
any portion of Pre-Construction Services specified in this Agreement. Such delays or
hindrances, if
any, will be solely compensated for by an extension of time for such
reasonable period and may be mutually agreed between the parties. It is understood
and agreed, however, that permitting CM@Risk to proceed to complete any such Services,
in whole or in part after the date to which the time of completion may have been extended,
will in no way act as a waiver on the part of City of any of their respective legal rights herein.
17.8.4
No compensation to CM@Risk will be allowed contrary to Article I, Chapter I, Title 34 of the
Arizona Revised Statutes.
17.8.5
If any service(s) executed by CM@Risk is abandoned or suspended in whole or in part, for
a period of more than 180 days through no fault of CM@Risk, CM@Risk is to be paid for
the services performed prior to the abandonment or suspension.
17.9
SURVIVAL OF THE DESIGN SERVICES AGREEMENT, DUTIES, OBLIGATIONS AND
WARRANTIES
If the GMP Proposal is accepted by City and a Construction Agreement is entered into
between City and CM@Risk, the duties, obligations and warranties of CM@Risk under the
Pre- Construction Services Agreement survive and are incorporated into the resulting
Construction Agreement.

CALCULATING DELAYS AND DAMAGES
The purpose of this policy statement is to establish guidelines and procedures for negotiation between
the Contractor and City of Chandler relating to compensation for delays pursuant to Arizona Revised
Statutes (A.R.S.) 34-221(F). This policy statement contains notice requirements in addition to those set
forth in the Agreement Documents, and will be the Agreement Provision contemplated by that statute.
NOTE: As used herein, the term “Engineer” will refer to the City of Chandler City Engineer or
his/her designated representative. Nothing in this Policy Statement will be construed to void any
provision in the Agreement which requires timely notice of delays or provides for arbitration or
any other procedure for settlement or provides for liquidated damages.
I.
TYPES OF DELAYS:
For the purposes of this document, there are essentially four types of delays encountered by
City of Chandler Construction Contractors; excusable/compensable, excusable/non-
compensable, non- excusable, and concurrent. Only delays that extend Agreement
Completion Time set forth in the Agreement Document will be considered for issues
relating to Agreement extensions or additional compensation. All other delays are
considered to be activity delays and do not entitle the Contractor to either time extensions
or additional compensation. Agreement Completion Time will be defined as the date set forth
in Maricopa Association of Governments (MAG) Uniform Standard Specification Section 101
and as may be modified by the Agreement Documents.
A.
Excusable/Compensable:
These are delays caused solely by the City’s actions or inactions, are unreasonable
under the circumstances, and which were not within the contemplation of the
parties to the Agreement at or prior to the time of execution of the Agreement.
Since the Contractor presumably has no control over the events causing the delay,
he may be entitled to both Agreement time extensions and additional compensation
for delay damages. Further, he/she may be entitled to additional compensation from
the impact of that delay on other work. Examples of excusable/compensable (E/C)
delays include: failure to properly locate an underground City-owned utility within 2
feet of the actual location; failure to relocate City-owned utilities far enough in
advance of construction in an area where the Contractor is scheduled to work that
it delays start or completion of the Contractor’s regularly scheduled work; failure
to provide City-furnished equipment or materials in a timely manner if required by
the Agreement; failure to acquire necessary Right-of-Way or Public Utility Easements
prior to the Contractor beginning Work in the area; failure to timely return Shop
Drawings or other Agreement Submittals in accordance with the Agreement;
unreasonable delay by the City in making decisions which affect critical activities;
surveying errors when the City is contractually responsible for providing Project
Surveying. This list is not meant to be all inclusive, but is intended merely as examples
of the type of City action or inaction which can result in a Contractor’s claim for
additional time and compensation.
App’d 7/20/2022
APP-3 of 33
General Conditions
Appendix 1
B.
Excusable/Non-compensable:
These are delays over which neither the City nor the Contractor had control. Since
both parties to the Agreement have been potentially damaged by the delay, but
neither have caused it, only Time Extensions are warranted. Examples of excusable,
non-compensable (E/N) delays include: unusually severe weather; fire; acts of God;
failure of non-City owned utilities (SRP, CenturyLink, Cable TV, Southern Pacific
Railroad, and Southwest Gas, etc.) to properly or timely locate accurately; failure of
non-City owned utilities to relocate in advance of construction; the voluntary or
involuntary filing for Bankruptcy protection by a Supplier or Subcontractor which
causes the Supplier/Subcontractor to fail to meet a contractual deadline provided the
Contractor can provide documentation that he/she executed the required Purchase
Orders/Subcontract Agreements and received delivery schedules which, if met,
would have eliminated the delay; delays as a result of an incomplete shutdown of a
City or non-City owned utility main (the City does not guarantee a complete
shutdown). This list also is not necessarily all inclusive but merely indicative of type
and class of E/N delays.
C.
Non-excusable/Non-compensable:
These are delays caused by the actions or inactions of Contractor or an officer,
employee, agent, Subcontractor, Supplier or any other party for whom the Contractor
is responsible. Since the Contractor has assumed responsibility for the risks
associated with the events that caused the delay, he/she are not entitled to either time
extensions or monetary delay damages. All non-excusable delays are also non-
compensable. Examples of non- excusable, non-compensable (N/N) delays include:
failure to perform by the Contractor, its Subcontractors and/or Suppliers (except as
noted in section I.B above); failure to provide adequate labor, materials, and/or
equipment on the Project; failure to perform contractually-required coordination
with utilities, agencies and other Contractors; failure to notify the Engineer, in writing,
of delay impacts within two working days, as required by MAG 104.2.3, or the next
work day, as required by MAG 109.8.2; failure to timely submit Shop Drawings; failure
to pothole or otherwise visually locate utilities sufficiently ahead of the Work to allow
the Engineer to direct corrective action when necessary; delays due to retesting of
previously failed work, re-inspection, and/or restaking resulting from faulty
workmanship, poor quality control, or lack of compliance with Agreement
Specifications. Again, this list is not necessarily all inclusive.
D.
Concurrent:
When two or more delays occur simultaneously or overlap, each delay is analyzed
separately to determine its impact on the overall project completion date based on
when that delay started. Once again, only those delays which actually extend the
Agreement completion time are considered as delays. The concurrent delay is
considered an additional delay only to the extent it prolongs the delay to the
Agreement Completion Time beyond the date that the one it is concurrent with had
already delayed that date. For example, if two delays are concurrent, and one is five
days long and the second is seven days long, the second concurrent delay will only
extend the Agreement Completion Time by two days. The same method of analysis is
App’d 7/20/2022
APP-4 of 33
General Conditions
Appendix 1
used when there are multiple concurrent delays. Only those extending the Project
Completion Date are considered to be delays for the purposes of this policy. The
portion of each concurrent delay that delays the completion of the work is classified
in the same manner as described previously for individual delays and being either E/C,
E/N or N/N.
An example of a concurrent delay is where the City delays furnishing material, but
the Contractor could not have installed it anyway due to unusually severe weather. The
effect of the first delaying activity will extend for the full duration and will be
considered controlling on the Contractor’s schedule. A subsequent, concurrent delay
will thereafter only be considered to effect the project completion (if at all) once the
first delaying activity has ceased to impact the project completion. In this case, if the
unusually severe weather continued and delayed the work after the material was
delivered, the first portion of the delay would be classified E/C (delay for material)
and the second as E/N (delay due to unusually severe weather). Using the procedure
set forth above, the entire concurrent portion would be considered E/C as shown in
the chart which follows.
Example of a Concurrent Delay:
E/C Delay
E/N Delay
City Related Material Delay
Rain Delay
II.
ANALYZING THE DELAY:
The Contractor must provide all documents required or requested by the Engineer to analyze the
delay(s). It is important to understand that, prior to the delay analysis, delays and their impacts are
alleged issues. The information the Contractor provides will be compared with the Inspector’s Daily
Log, Schedules and other available Project information and together they will support or refute that
delays occurred and, if so, how they impact other work and the overall project completion. The
Contractor’s delay in providing these documents will be considered prima facie evidence that either
the delay did not occur or it did not impact the Project Completion Date and any claim for time
extension or damages will be denied.
The Engineer will accept delay analyses in CPM format, as these may demonstrate to his/her
satisfaction whether or not Project Completion has been impacted by a specific event. If the Contractor
chooses not to use CPM scheduling procedures, then the burden will be on the Contractor to prove
to the Engineer’s satisfaction that the Project Completion has been impacted. The procedures
App’d 7/20/2022
APP-5 of 33
General Conditions
Appendix 1
below assume that the Contractor is using CPM scheduling methods. As a minimum the Contractor
must provide the following materials to the Engineer:
A.
As-Planned Schedule. The initial construction schedule, required by the Agreement
Documents, will be considered the baseline schedule. It is to the Contractor’s
advantage that the As-Planned (baseline) Schedule be as detailed as possible in order
for delays, as they occur, to be incorporated into the schedule in representative
locations. It is also to the Contractor’s advantage to use a computer software program
to generate the schedule since updated schedules are required monthly by the
Agreement Documents and since updated schedules are required to support
delays and requests for additional compensation for delays. The As-Planned
(baseline) Schedule must be presented in network format which clearly shows the
interrelationships of the activities. The Contractor must also provide a printout of the
activities showing early start, early finish, late start, late finish, duration and float. The
activity list printout must also indicate predecessor and successor activities.
B.
As-Built Schedules. The as planned (baseline) schedule must be updated with
complete progress-to-date information (actualized) up to the date of the start of the
alleged delay. Each updated schedule will serve as the as-built schedule for analyzing
the alleged delay and provide a new baseline as-planned schedule for the next delay.
This process must be repeated for each alleged delay as it occurs. In updating the
baseline schedule, the alleged delay must be treated as an activity and inserted into the
schedule as a predecessor to the impacted activity (ies). When an activity that has
already started is impacted, it is preferable to divide this activity into two parts and
show the impact affecting the second part. For schedules which incorporate a time
line (or data date), the delay activity must be inserted at the time it actually occurred.
Some software scheduling programs have a PAUSE-RESUME feature that can be
used to facilitate the requirements. The updated schedule must also be accompanied
by a listing of activities as with the baseline schedule. This activities list must contain
the alleged delay as an activity showing the duration and the activities which are
predecessors and successors to it. When computer generated schedules are used,
the Contractor must provide, in electronic media format, the complete data files for
the updated schedule that included the delay activity, preferably either in Suretrak
or in Microsoft Project. Each electronic media must contain a label identifying the
Project name, Contractor’s name, program name and version number, data date
and project finish date.
C.
Other Documents: In order to determine the amount of the alleged delay and if it
is compensable, the Contractor must provide all backup documentation relevant to the
issue and as required by the Engineer. This documentation must include copies of
such items as: purchase orders; delivery schedules; correspondence; memoranda of
telephone calls; force account daily worksheets (initialed by the Inspector); payroll
data; estimating (bid) worksheets; and any other materials which may be requested
by the Engineer.
D.
Procedure: Only after receipt of sufficient documentation will the Engineer analyze
each alleged delay and determine if it is supported or refuted. If supported, the
Engineer will determine if it is excusable or non-excusable, compensable or non-
App’d 7/20/2022
APP-6 of 33
General Conditions
Appendix 1
compensable. If the Engineer determines that the delay did not affect the Project
Completion, the as-planned schedule, which has been updated to the date of the
alleged delay, must be revised to indicate this. If the Engineer determines the delay
did occur but was N/N, then no time extension will be granted. It is imperative that
an actualized schedule be submitted as soon as the occurrence of the alleged delay
is known. In no event will the Contractor submit an actualized updated schedule
later than 60 days after the occurrence of the alleged delay becomes known.
If the Engineer determines the delay did occur and was excusable but, due to a
reason listed in section I.B. is non-compensable, he/she will determine the length of
the E/N delay and prepare a Change Order to add that time to the Agreement. The
Engineer’s decision will be final.
If the Engineer determines the delay was excusable and compensable, he/she will
determine the length of the E/C delay and proceed to review the Contractor’s damage
calculations in accordance with Section III. The Engineer will check the Contractor’s
calculations, review the backup documentation provided, and prepare a Change
Order to cover both the additional compensation and the time extension. The
Engineer’s decision on both the time extension and additional compensation for the
delay will be final.
If the issue involves a concurrent delay, the Engineer will analyze available data
to determine the portions which are E/C, E/N, and/or N/N as described above. The
Engineer will proceed to determine the length of E/C delay and verify the Contractor’s
delay damage calculations, if any are provided. Upon completion of this review, the
Engineer will prepare a Change Order for the Contractor’s review and signature.
The Engineer’s decision regarding excusable delay and additional compensation for
the delay is final.
The amount of time the Engineer will require to analyze the alleged delay(s) will
depend upon the Engineer’s workload, the complexity of the delay analysis,
availability of supporting data, extent of cooperation by the Contractor, and other
factors beyond the Engineer’s control. It is entirely possible other delay(s) may occur
while the Engineer is analyzing particular claim for delay(s). The Engineer’s failure to
respond to the Contractor in a set period of time will not be used as the basis for
a further delay claim or as justification for extending and existing delay claim. The
time required for delay analysis by the Engineer will not be counted against the time
allotted for processing Final Payment as required by (MAG Section 109.7(B)) or the
release of retention and Final Payment as prescribed by A.R.S. Arizona Revised
Statutes §34-221.
III.
CALCULATING MONETARY DELAY DAMAGES:
Additional compensation for delay, when authorized by the Engineer, will be calculated in accordance
with MAG Section 109.5 ACTUAL COST WORK with the following exceptions:
A.
No additional compensation or other monetary damages will be awarded or paid for
any loss of anticipated profits by the Contractor, Subcontractors or Suppliers.
App’d 7/20/2022
APP-7 of 33
General Conditions
Appendix 1
B.
No additional compensation or other monetary damages will be awarded for home
office overhead or non-project general conditions of the Contractor, Subcontractors
or Suppliers.
C.
Equipment:
1.
Contractor-owned equipment rate calculations must be computed in
accordance with Section 109.04(D)(3), Arizona Department of Transportation
“Standard Specifications for Road and Bridge Construction,” 2008 or latest
edition and as modified herein. Year and regional adjustment factors must be
based on the most recent publications of the Rental Rate Blue Book for
Construction
Equipment, published
by
the
Equipment
Guide-Book
Company, San Jose, CA, same as provided by ADOT and in print as of the
date of alleged delay. In no event will the compensation for Contractor-
owned equipment exceed the purchase price, including tax, paid by the
Contractor for the equipment. Compensation will not be allowed for small tools
or equipment that show a daily equipment rental rate of less than $5.00 per
day or for unlisted equipment that has a value of less than for hundred
dollars ($400.00).
2.
For leased and rented equipment or equipment not otherwise listed in the
Blue Book, rental contracts, or other supporting data will be used to establish
the hourly rate. No hourly operating expense will be allowed for delay on
standby equipment. In no case will equipment be considered for rental which
exceeds the hourly rate for the first eight hours and the daily rate divided
by eight for all additional hours as compared with similar equipment listed in
the Blue Book. The hourly standby rate must be computed as the lesser of:
a.
Dividing the monthly invoice or rental value by 176 hours
per month when the equipment is utilized by the Contractor
for more than three weeks;
b.
Dividing the monthly invoice or rental value by 40 hours per
week when the equipment is utilized by the Contractor for
more than three days.
In no event will compensation be paid for delay at more than
8 hours per day or 40 hours per week.
3.
Except for vehicles used by supervisory personnel, all equipment will be paid
at the “standby” rate during the delay period.
4.
Equipment brought solely to mitigate the delay (such as pumps, light plants,
etc.) may be paid in accordance with ADOT section 109.04(D) (3).
5.
The Blue Book regional adjustment will apply in determining rental rates.
D.
Material:
Allowable material charges may include, in addition to material incorporated in the
App’d 7/20/2022
APP-8 of 33
General Conditions
Appendix 1
work material used to mitigate the delay such as barricades, plates, shoring, cold
mix, etc. Except in emergencies the Contractor will not employ such material
without the prior written approval of the Engineer.
E.
Labor:
1.
Except for Supervisory Personnel (Superintendent, Project Engineer, and
Foremen), labor wages will not be paid after the first one-half day of claimed
delay or impact. It is expected the Contractor will reassign or layoff
unneeded employees.
2.
For Foreman wages to be included, that Foreman must have been actively
employed on the project prior to the commencement of the delay and be
directly responsible for the activity being delayed.
3.
Labor burden must be actual amounts incurred but must not exceed the
ADOT approved rate.
F.
All costs (equipment, material, and labor) must be substantiated by the City of
Chandler’s Daily Work Reports.
IV.

COST REDUCTION INCENTIVE PROPOSALS
FOR DESIGN BID BUILD AGREEMENTS
The Contractor may submit to the Engineer proposals for modifying the Plans, Specifications, or
other requirements of the Agreement for the sole purpose of reducing the total cost of Project
construction. The proposals must not impair in any manner the essential functions or characteristics
of the project; including but not limited to service life, economy of operations, ease of maintenance,
desired appearance, compatibility with existing or planned equipment, standardization of systems,
or design and safety standards.
It must not be inferred from this Policy that the Engineer is required to consider any proposal
submitted.
Submissions that propose changes in the basic design of a bridge, propose changes in pipe line
size, materials, bedding conditions, pipe specifications; or that propose any change in pavement design
will not be considered.
Proposals submitted pursuant to this Policy will be identified as Cost Reduction Incentive Proposals.
They must be submitted in writing and, at a minimum, contain the following.
1.
Complete the attached or similar cost reduction incentive proposal form.
2.
A description of both the existing Agreement Requirements for performing the work
and the proposed changes.
3.
All Engineering Drawings and computations necessary for the thorough and
expeditious evaluation.
4.
An itemization of the existing Agreement Requirements that must be changed if the
Proposal is adopted and a recommendation as to the manner in which the change
should be made.
5.
A detailed estimate of the cost of performing the Work under the existing
Agreement and under the proposed changes, including the cost of developing and
implementing the changes.
6.
The Agreement items affected by the proposed changes and any variations in
quantities resulting from the changes.
7.
An objective estimate of any effects the proposal will have on collateral cost to the
City, costs of related items, and cost of maintenance and operation.
8.
A statement as to the effect that the Proposal will have on the time for the completion
of the Project.
9.
A statement as to the time by which a Change Order adopting the Proposal must
be executed or when the Engineer must have given verbal approval.
App’d 7/20/2022
APP-12 of 33
General Conditions
Appendix 2
Proposals will be processed expeditiously; however, the City will not be liable for any delay in acting
upon any Proposal nor for any failure to accept any Proposal pursuant to this Special Provision.
The Engineer will be the sole judge of the acceptability of a Proposal and of the estimated net savings
in construction costs from the adoption of all or any part of the Proposal. The Contractor will be
notified in writing by the Engineer as to whether his/her Proposal has been accepted. The decision by
the Engineer is final.
When the City deems such action to be appropriate, it reserves the right to require the Contractor to
share equally in the cost to the City of investigating, evaluating, and processing the proposal as a
condition for the consideration of such Proposal. Such cost must be shared whether the Proposal is
accepted or rejected. When such a condition is imposed, the City will estimate these costs and the
Contractor must indicate his acceptance thereof in writing. Such acceptance will authorize the City to
deduct the Contractor’s share of the costs from any monies due or that may become due to the
Contractor under the Agreement.
If the Contractor’s Proposal is accepted in whole or in part, the necessary Agreement Modifications
and Agreement Price Adjustments will be affected by the execution of a Change Order which will
specifically state that it is executed pursuant to this Special Provision.
The Contractor must continue to perform the work in accordance with the requirements of the
Agreement until a Change Order incorporating the Proposal has been executed or until he/she has
been given verbal approval by the Engineer that his/her Proposal has been accepted. If the Change
Order has not been executed or he/she has not been given verbal approval on or before the date
specified on the attached cost reduction incentive proposal form or on or before such other date as the
Contractor may have subsequently specified in writing, the Proposal may be deemed to be rejected.
The executed Change Order will incorporate the changes in the Plans, Specifications, or other
requirements of the Agreement which are necessary to permit the Proposal, or such part of it which
has been accepted, to be put into effect, and will include any condition – upon which the City’s
approval thereof is based, if such approval is conditional. The executed Change Order may also
extend the time for the completion of the Agreement if such an extension has been deemed to be
warranted by the Engineer as a result of his evaluation of the Proposal.
The executed Change Order will also establish the estimated net savings in the cost of performing
the Work attributable to the Proposal effectuated by the Change Order. In determining the net
savings, the right is reserved to the Engineer to disregard the Agreement bid prices if, in his/her
judgment, such prices do not represent a fair measure of the value of the Work to be performed or
to be deleted. The net savings will be established by determining the Contractor’s cost of performing
the Work, taking into account his/her cost of developing the Proposal and implementing the change,
and reducing this amount by any ascertainable collateral costs to the City. The executed Change
Order may provide that the Contractor be paid 50 percent of the estimated net savings amount.
The executed Change Order may also provide for the adjustment in Agreement prices. Agreement
prices may be adjusted by subtracting the City’s share of the accrued net savings.
The amount specified to be paid to the Contractor in the executed Change Order which effectuates a
Cost Reduction Proposal will constitute full compensation to the Contractor for the Cost Reduction

Proposal and the performance of the work thereof pursuant to the said Change Order.
Upon acceptance of a Cost Reduction Incentive Proposal, any restrictions imposed by the
Contractor on its use or on disclosure of the information will become void, and the City thereafter
will have the right to use all or any part of the Proposal without obligation or compensation of any
kind to the Contractor.

COST OF THE WORK
(APPLICABLE SOLELY TO CONSTRUCTION MANAGER AT RISK AND JOB ORDER CONTRACTING)
SECTION 1 – COSTS TO BE REIMBURSED
1.1 Cost of the Work
The term Cost of the Work will mean costs necessarily incurred by Contractor in the proper
performance of the Work. Such costs must be at rates not higher than the standard paid at the place
of the Project except with prior consent of City. The Cost of the Work will include only the items set
forth in this Section 1.
1.2 Labor Costs
1.2.1
Wages of construction workers directly employed by the Contractor to perform the
construction of the Work at the site or, with City’s approval, at off-site workshops. Cost to
be reimbursed will be the actual wages paid to the individuals performing the work.
1.2.2
Wages or salaries of the Contractor’s supervisory and administrative personnel when
stationed at
the site with City’s approval. No Contractor personnel stationed at the
Contractor’s home or branch offices will be charged to the Cost of the Work. Non-field office
based Contractor management and support personnel are expected to provide service and
advice from time to time throughout the job and his/her time devoted to Project matters is
considered to be covered by the Contractor’s Fee.
1.2.3
Wages and salaries of Contractor’s supervisory or administrative personnel who would
normally be stationed at the field office in accordance with Section 1.2.2 but who become
engaged, at factories,
workshops or on the road, in expediting the production or
transportation of materials or equipment required for the Work, but only for that portion of
his/her time required for the Work. Employee
bonuses and/or costs associated with
Employee Stock Ownership Plans (“ESOP”) will not be considered reimbursable labor or
labor burden costs and will be considered non-reimbursable costs considered to be covered
by the Contractor’s Fee.
1.2.4
Costs paid or incurred by Contractor for taxes, insurance, contributions, assessments and
benefits required by law or collective bargaining agreements and, for personnel not
covered by such agreements, customary benefits such as sick leave, medical and health
benefits, holiday, vacations and pensions, provided such costs are based on wages and
salaries included in the Cost of the Work under Subparagraphs 1.2.1 through 1.2.3.
1.2.4.1 Cost of the Work will include the actual net cost to Contractor for worker’s compensation
insurance attributable to the wages chargeable to the Cost of Work per this Agreement. The
actual
net cost of worker’s compensation must take into consideration all cost
adjustments due
to
experience modifiers, premium discounts, policy dividends,
retrospective rating plan premium adjustments, assigned risk pool rebates, any applicable
weekly maximums, etc. Contractor may
charge an estimated amount for worker’s
compensation insurance costs, but will make appropriate cost adjustments to actual costs
within 45 days of receipt of actual cost adjustments from the insurance carrier.

APP-24 of 33
General Conditions
Appendix 9 – CM@Risk & JOC
1.2.4.3 Overtime wages paid to salaried personnel (if approved in advance in writing by City) will
be reimbursed at the actual rate of overtime pay paid to the individual. No time charges for
overtime hours worked on the Project will be allowed if the individual is not paid for the
overtime worked.
1.2.4.4 Any overtime premium or shift differential expense to be incurred by Contractor for hourly
workers will require City’s advance written approval before the incremental cost of the
overtime premium or shift differential will be considered a reimbursable cost. If the
Contractor is required to work overtime as a result of an inexcusable delay or other
coordination problems caused by the Contractor or anyone he/she is responsible for,
the overtime premium and/or shift differential expense portion of the payroll expense and
related labor burden costs will be considered as cost not to be reimbursed.
1.2.4.5 Reimbursable labor burden costs will be limited to payroll taxes, worker’s compensation
insurance, the employer’s portion of union benefit costs for union employees working on the
Project, and the actual verifiable fringe benefit costs incurred by Contractor for non-union
individuals working on the Project subject to the following maximum percentages for the
following reimbursable non-union fringe benefit costs. The following maximums (as a
percentage of reimbursable actual wages by individual) will apply for each of the following
types of fringe benefit costs specifically attributable to each of the non-union personnel
working on the Project:
•
Medical Insurance, Dental, Life & AD&D Insurance:
12.00%
•
Holiday, vacation and other paid time not worked:
10.00%
• Pension Plan Contributions to Vested Employee Account,
Simplified Employee Pension Plans, or 401K matching plans
(Note: ESOP related costs are covered by the Contractor Fee)
10.00%
For non-union personnel, no other fringe benefit costs (other than the three specific
categories listed immediately above, will be considered reimbursable Cost of Work. Any labor
burden costs that are in excess of the amounts considered reimbursable or are otherwise
not considered reimbursable under the terms of this agreement are intended to be covered
by the Contractor Fee.
1.3
Subcontract Costs
1.3.1
Payments made by Contractor to Subcontractors in accordance with the requirements of
the subcontracts.
1.3.2
For Scope of Work Bid Packages typically performed by Subcontractors, Contractor may
“self- perform” such work on an actual cost basis subject to an agreed upon Guaranteed
Maximum Price for the “self-performed work”. The Contractor must, unless agreed to by City
in writing, bid his/her proposed guaranteed Maximum Price for the work to be “self-
performed” against at least three other interested trade Contractors. All savings under any
such Subcontract for “self-performed work” must be applied to reduce the Cost of Work under
the Agreement and the Guaranteed Maximum Price. For purposes of defining “self-
performed work” subject to this provision, any division of Contractor, or any separate
Contractor or Subcontractor that is partially owned or wholly owned by the Contractor or any
of his/her employees or employee’s relatives will be considered a related party entity and
will be subject to this provision regarding “self-performed work”. No self-performed work will
App’d 7/20/2022
APP-25 of 33
General Conditions
Appendix 9 – CM@Risk & JOC
be allowed to be performed on a Fixed Price basis.
1.3.3
Contractor (with respect to its Suppliers, Subcontractors and all lower tier Subcontractors)
must provide City advance written notice and must obtain City’s approval for any proposed
Subcontract Change Order, Material Purchase Order, or other financial commitment in an
amount in excess of $5,000 prior to placing such order or entering into such agreement
(regardless of whether or not any such commitment will affect the prime Agreement
Guaranteed Maximum Cost). It is agreed that sums applicable to any Subcontract Change
Order, Purchase Order or other financial commitment entered into in violation of the above
notice and approval requirement will not be included in the amounts owning to Contractor,
Subcontractors or Suppliers whether as Costs of the Work or as reasonable termination costs
in the event of termination.
1.4
Costs of Material and Equipment Incorporated in the Completed Construction
1.4.1
Costs, including transportation and storage, of materials and equipment incorporated or
to be incorporated in the completed construction.
1.4.2
Costs of materials described in the preceding Subparagraph 1.4.1 in excess of those
actually installed to allow for reasonable waste and spoilage. Unused excess materials, in
any, will become City’s property at the completion of the Work or, at City’s option, may be
sold by the Contractor. Any amounts realized from such sales must be credited to City as a
deduction from the Cost of Work.
1.4.3
Proceeds from the sale of recyclable materials, scrap, waste, etc. will be credited to job cost.
1.5
Costs of Other materials and Equipment, Temporary Facilities and Related Items
1.5.1
Costs, including transportation and storage, installation, maintenance, dismantling and
removal of materials, supplies, temporary facilities, machinery, equipment and hand tools
not customarily owned by construction workers, that are provided by the Contractor at the
site and fully consumed in the performance of the Work; and cost (less salvage value) of such
items if not fully consumed, whether sold to others or retained by Contractor. Cost for items
previously used by Contractor will mean fair market value.
1.5.2
Rental charges for temporary facilities, machinery, equipment, and hand tools not
customarily owned by construction workers that are provided by Contractor at the site,
whether rented from Contractor or others, and costs of transportation, installation, minor
repairs and replacements,
dismantling and removal thereof. Rates and quantities of
equipment rented will be subject to City’s prior written approval.
1.5.2.1 The Projected usage for each piece of equipment to be rented for use on the Project and
the estimated total rentals must be considered by Contractor before the piece of equipment
is rented so that an appropriate rent versus buy decision can be made. Purchased
equipment must be considered “job owned”. At the completion of the Project, Contractor
must transfer title and possession of all remaining job-owned equipment to City, or
Contractor may keep any such equipment for an appropriate fair market value credit to job
cost, which will be mutually agreed to by City and Contractor.
1.5.2.2 Each piece of equipment to be rented must have hourly, daily, weekly and monthly rates and

piece of equipment is no longer needed for the work, no rental charges will be reimbursed
if the piece of equipment remains at the jobsite for the convenience of Contractor.
1.5.2.3 Equipment Rental Rates
1.5.2.3.1 Compensation for equipment used on the Project will be paid in accordance with the
Equipment Plan submitted by Contractor in the accepted GMP Proposal and no payments
will be made in excess of the rates set forth in the Equipment Plan, or actual documented
costs, whichever is less.
1.5.2.3.2 All equipment rental rates and costs are subject to City’s right to audit when submitted as
part of Equipment Plan and/or at any time during the Project.
1.5.2.4 The aggregate rentals chargeable for each piece of Contractor owned tools or equipment must
not exceed 50% of the fair market value of such equipment at the time of its commitment to
the Work. The original purchase price and date of purchase of the equipment will be
documented with a copy of the purchase invoice for the piece of equipment. Such aggregate
limitations will apply and no further rentals will be charged even if a piece of equipment is taken
off the job and is later replaced by a similar piece of equipment. For purposes of computing
the aggregate rentals applicable to aggregate rental limitations, rental charges for similar
pieces of equipment will be combined if the pieces of equipment were not used at the same
time.
1.5.2.5 Fair market value for used material and equipment as referred to in the Agreement
Documents will mean the estimated price a reasonable purchaser would pay to purchase
the used material or equipment at the time it was initially needed for the job. Note: This is
usually lower than the price a reasonable purchaser would pay for similar new construction
material or construction equipment.
1.5.2.6 All losses resulting from lost, damaged or stolen tools and equipment will be the sole
responsibility of Contractor, and not City, and the cost of such losses will not be reimbursable
under the Agreement.
1.5.2.7 Contractor will be required to maintain a detailed equipment inventory of all job-owned
equipment (either purchased and charged to job cost or job-owned through aggregate
rentals) and such inventory must be submitted to City each month. For each piece of
equipment, such inventory should contain at a minimum (1) original purchase price or
acquisition cost (2) acquisition date (3) approved Fair Market Value at the time the piece of
equipment was first used on the job and (4) final disposition.
1.5.2.8 All costs incurred for minor maintenance and repairs will be reimbursed at actual cost. Such
costs include routine and preventative maintenance, minor repairs and other incidental costs.
Repairs and/or replacement of a capital nature are considered to be covered by the rental
rates. Major repairs and overhauls are not considered routine and ordinary; consequently
such costs are not reimbursable and are intended to be covered by the rental rates.

the Contractor. If the Contractor completes Work for less than the Agreement Price,
Contractor must credit the City a pro- rated amount for the unused portion of the bond
payment
1.6.1.1 Contractor’s actual cost for insurance will be considered to be included within the Maximum
limit for General Conditions Costs. All premiums for any insurance and bonds required for
the Project must reflect the net actual costs to Contractor after taking into consideration cost
adjustments due to experience modifiers, premium discounts, policy dividends, retrospective
rating plan premium adjustments, assigned risk pool rebates, refunds, etc.
1.6.1.2 The amount to be reimbursed to Contractor for all contractually required insurance will be
actual costs not to exceed a total of 2% of the Agreement Value, unless Contractor

The Contractor’s attention is directed to the following Arizona Revised Statutes:
a. ARS 40-360.22. Excavations, determining location of underground facilities; providing information.
This statute requires that no person shall begin excavation before the location and marking are complete or
the excavator is notified that marking is unnecessary and requires that upon notification, the Owner of the
facility shall respond as promptly as practical, but in no event later than two (2) working days. This section
is not applicable to an excavation made during an emergency that involves danger to life, health or property
if reasonable precautions are taken to protect underground facilities.
b. ARS 40-360.23. Making excavations in careful, prudent manner; liability for negligence. This statute
states that obtaining information as required does not excuse any person making any excavation from doing
so in a careful and prudent manner, nor shall it excuse such persons from liability for any damage or injury
resulting from his negligence.
c. ARS 40-360.28. Civil penalty; liability. If the Owner or operator fails to locate, or incorrectly locates
the underground facility, pursuant to this article, the Owner or operator becomes liable for resulting

102-2.4 Slope drains. Slope drains may be constructed of pipe, fiber mats, rubble, concrete, asphalt,
or other materials that will adequately control erosion.
102-2.5 Silt fence. Silt fence shall consist of polymeric filaments which are formed into a stable
network such that filaments retain their relative positions. Synthetic filter fabric shall contain ultraviolet
ray inhibitors and stabilizers to provide a minimum of six months of expected usable construction life. Silt
fence shall meet the requirements of ASTM D6461.
102-2.6 Other. All other materials shall meet commercial grade standards and shall be approved by the
RPR before being incorporated into the project.
CONSTRUCTION REQUIREMENTS
102-3.1 General. In the event of conflict between these requirements and pollution control laws, rules,
or regulations of other federal, state, or local agencies, the more restrictive laws, rules, or regulations shall
apply.
The RPR shall be responsible for assuring compliance to the extent that construction practices, construction
operations, and construction work are involved.
102-3.2 Schedule. Prior to the start of construction, the Contractor shall submit schedules in
accordance with the approved Construction Safety and Phasing Plan (CSPP) and the plans for
accomplishment of temporary and permanent erosion control work for clearing and grubbing; grading;
construction; paving; and structures at watercourses. The Contractor shall also submit a proposed method
of erosion and dust control on haul roads and borrow pits and a plan for disposal of waste materials. Work
shall not be started until the erosion control schedules and methods of operation for the applicable
construction have been accepted by the RPR.
102-3.3 Construction details. The Contractor will be required to incorporate all permanent erosion
control features into the project at the earliest practicable time as outlined in the plans and approved CSPP.
Except where future construction operations will damage slopes, the Contractor shall perform the
permanent seeding and mulching and other specified slope protection work in stages, as soon as substantial
areas of exposed slopes can be made available. Temporary erosion and pollution control measures will be
used to correct conditions that develop during construction that were not foreseen during the design stage;
that are needed prior to installation of permanent control features; or that are needed temporarily to control
erosion that develops during normal construction practices, but are not associated with permanent control
features on the project.
Where erosion may be a problem, schedule and perform clearing and grubbing operations so that grading
operations and permanent erosion control features can follow immediately if project conditions permit.
Temporary erosion control measures are required if permanent measures cannot immediately follow
grading operations. The RPR shall limit the area of clearing and grubbing, excavation, borrow, and
embankment operations in progress, commensurate with the Contractor’s capability and progress in
keeping the finish grading, mulching, seeding, and other such permanent control measures current with
the accepted schedule. If seasonal limitations make such coordination unrealistic, temporary erosion
control measures shall be taken immediately to the extent feasible and justified as directed by the RPR.

anticipated storm event.
c. When sediment escapes the construction site, off-site accumulations of sediment must be routinely
removed at a frequency sufficient to ensure no adverse effects on water quality.
The SWPPP must describe good housekeeping procedures to prevent litter, construction debris, and
construction chemicals exposed to storm water from becoming a pollutant source for storm water
discharges.
The SWPPP must include a description of and identify interim and permanent stabilization practices for
the construction site, including a schedule of when the practices will be implemented. The SWPPP shall
document those areas where existing vegetation will be preserved.
The Contractor must initiate stabilization measures within 14 calendar days in those areas where
construction activities have temporarily or permanently ceased, except:
a. Where stabilization by the 14th day is precluded by frozen ground conditions, stabilization
measures must be initiated as soon as practicable.
b. Where construction activity on a portion of the site has temporarily ceased, but earth disturbing
activities will resume in that area within the 14 days. In this event, temporary stabilization measures
do not have to be initiated on that portion of the site.
c. When the site is using vegetative stabilization measures and it is during seasonally arid conditions,
vegetative stabilization measures must be initiated as soon as practicable.
The Contractor must maintain the following records as part of the SWPPP:
a. Dates when major grading activities occur;
b. Dates when construction activities temporarily or permanently cease on a portion of the site;
c. Dates when stabilization measures are initiated and completed, and the reasons for any delay.
The SWPPP must describe structural practices to divert flows from exposed soils, store flows or otherwise
limit runoff and the discharge of pollutants from exposed areas of the site to the degree attainable.

Preparation/Removal of Existing
Pavements
101-3.2 Preparation of joints and cracks prior to overlay/surface treatment. Remove
all vegetation and debris from cracks to a minimum depth of 1 inch. If extensive vegetation exists, treat the
specific area with a concentrated solution of a water-based herbicide approved by the RPR. Fill all cracks
greater than 1/4 inch wide with a crack sealant per ASTM D6690. The crack sealant, preparation, and
application shall be compatible with the surface treatment/overlay to be used. To minimize contamination
of the asphalt with the crack sealant, underfill the crack sealant a minimum of 1/8 inch, not to exceed 1/4
inch. Any excess joint or crack sealer shall be removed from the pavement surface.
101-3.3 Removal of Foreign Substances/contaminates prior to seal-coat or
remarking. Removal of foreign substances/contaminates from existing pavement that will affect the
bond of the new treatment shall consist of removal of rubber, fuel spills, oil, crack sealer, at least 90% of
paint, and other foreign substances from the surface of the pavement. Areas that require removal are
designated on the plans and as directed by the RPR in the field during construction.
Chemicals, high-pressure water, heater scarifier (asphaltic concrete only), cold milling, or sandblasting may
be used. If chemicals are used, they shall comply with the state’s environmental protection regulations.
Removal methods used shall not cause major damage to the pavement, or to any structure or utility within
or adjacent to the work area. Major damage is defined as changing the properties of the pavement, removal
of asphalt causing the aggregate to ravel, or removing pavement over 1/8 inch deep. If it is deemed by the
RPR that damage to the existing pavement is caused by operational error, such as permitting the application
method to dwell in one location for too long, the Contractor shall repair the damaged area without
compensation and as directed by the RPR.
Removal of foreign substances shall not proceed until approved by the RPR. Water used for high-pressure
water equipment shall be provided by the Contractor at the Contractor's expense. No material shall be
deposited on the pavement shoulders. All wastes shall be disposed of in areas indicated in this specification
or shown on the plans.
101-3.4 Concrete spall or failed asphaltic concrete pavement repair.
a. Repair of concrete spalls in areas to be overlaid with asphalt. The Contractor shall
repair all spalled concrete as shown on the plans or as directed by the RPR. The perimeter of the repair shall
be saw cut a minimum of 2 inches outside the affected area and 2 inches deep. The deteriorated material
shall be removed to a depth where the existing material is firm or cannot be easily removed with a geologist
pick. The removed area shall be filled with asphalt mixture with aggregate sized appropriately for the depth
of the patch. The material shall be compacted with equipment approved by the RPR until the material is
dense and no movement or marks are visible. The material shall not be placed in lifts over 4 inches in depth.
This method of repair applies only to pavement to be overlaid.
b. Asphalt pavement repair. The Contractor shall repair all spalled concrete as shown on the
plans or as directed by the RPR. The failed areas shall be removed as specified in paragraph 101-3.1b. All

Excavation, Subgrade, and
Embankment
Item P-152 Excavation, Subgrade, and Embankment
DESCRIPTION
152-1.1 This item covers excavation, disposal, placement, and compaction of all materials within the
limits of the work required to construct safety areas, runways, taxiways, aprons, and intermediate areas as
well as other areas for drainage, building construction, parking, or other purposes in accordance with these
specifications and in conformity to the dimensions and typical sections shown on the plans.
152-1.2 Classification. All material excavated shall be classified as defined below:
a. Unclassified excavation. Unclassified excavation shall consist of the excavation and disposal
of all material, regardless of its nature.
152-1.3 Unsuitable excavation. Unsuitable material shall be disposed in designated waste areas as
shown on the plans. Materials containing vegetable or organic matter, such as muck, peat, organic silt, or
sod shall be considered unsuitable for use in embankment construction. Material suitable for topsoil may
be used on the embankment slope when approved by the RPR.
CONSTRUCTION METHODS
152-2.1 General. Before beginning excavation, grading, and embankment operations in any area, the
area shall be cleared or cleared and grubbed in accordance with Item P-151.
The suitability of material to be placed in embankments shall be subject to approval by the RPR. All
unsuitable material shall be disposed of in waste areas as shown on the plans. All waste areas shall be graded
to allow positive drainage of the area and adjacent areas. The surface elevation of waste areas shall be
specified on the plans or approved by the RPR.
When the Contractor’s excavating operations encounter artifacts of historical or archaeological significance,
the operations shall be temporarily discontinued and the RPR notified per Section 70, paragraph 70-20. At
the direction of the RPR, the Contractor shall excavate the site in such a manner as to preserve the artifacts
encountered and allow for their removal. Such excavation will be paid for as extra work.
Areas outside the limits of the pavement areas where the top layer of soil has become compacted by hauling
or other Contractor activities shall be scarified and disked to a depth of 4 inches, to loosen and pulverize
the soil. Stones or rock fragments larger than 4 inches in their greatest dimension will not be permitted in
the top 6 inches of the subgrade.
If it is necessary to interrupt existing surface drainage, sewers or under-drainage, conduits, utilities, or
similar underground structures, the Contractor shall be responsible for and shall take all necessary
precautions to preserve them or provide temporary services. When such facilities are encountered, the
Contractor shall notify the RPR, who shall arrange for their removal if necessary. The Contractor, at their
own expense, shall satisfactorily repair or pay the cost of all damage to such facilities or structures that may
result from any of the Contractor’s operations during the period of the contract.

Excavation, Subgrade, and
Embankment
a. Blasting. Blasting shall not be allowed.
152-2.2 Excavation. No excavation shall be started until the work has been staked out by the
Contractor and the RPR has obtained from the Contractor, the survey notes of the elevations and
measurements of the ground surface. The Contractor and RPR shall agree that the original ground lines
shown on the original topographic mapping are accurate, or agree to any adjustments made to the original
ground lines.
Digital terrain model (DTM) files of the existing surfaces, finished surfaces and other various surfaces were
used to develop the design plans.
Existing grades on the design cross sections or DTM’s, where they do not match the locations of actual spot
elevations shown on the topographic map, were developed by computer interpolation from those spot
elevations. Prior to disturbing original grade, Contractor shall verify the accuracy of the existing ground
surface by verifying spot elevations at the same locations where original field survey data was obtained as
indicated on the topographic map. Contractor shall recognize that, due to the interpolation process, the
actual ground surface at any particular location may differ somewhat from the interpolated surface shown
on the design cross sections or obtained from the DTM’s. Contractor's verification of original ground
surface, however, shall be limited to verification of spot elevations as indicated herein, and no adjustments
will be made to the original ground surface unless the Contractor demonstrates that spot elevations shown
are incorrect. For this purpose, spot elevations which are within 0.1 foot of the stated elevations for ground
surfaces, or within 0.04 foot for hard surfaces (pavements, buildings, foundations, structures, etc.) shall be
considered “no change”. Only deviations in excess of these will be considered for adjustment of the original
ground surface. If Contractor's verification identifies discrepancies in the topographic map, Contractor shall
notify the RPR in writing at least two weeks before disturbance of existing grade to allow sufficient time to
verify the submitted information and make adjustments to the design cross sections or DTM’s. Disturbance
of existing grade in any area shall constitute acceptance by the Contractor of the accuracy of the original
elevations shown on the topographic map for that area.
All areas to be excavated shall be stripped of vegetation and topsoil. Topsoil shall be stockpiled for future
use in areas designated on the plans or by the RPR. All suitable excavated material shall be used in the
formation of embankment, subgrade, or other purposes as shown on the plans. All unsuitable material shall
be disposed of as shown on the plans.
The grade shall be maintained so that the surface is well drained at all times.
When the volume of the excavation exceeds that required to construct the embankments to the grades as
indicated on the plans, the excess shall be used to grade the areas of ultimate development or disposed as
directed by the RPR. When the volume of excavation is not sufficient for constructing the embankments to
the grades indicated, the deficiency shall be obtained from borrow areas.
a. Selective grading. When selective grading is indicated on the plans, the more suitable material
designated by the RPR shall be used in constructing the embankment or in capping the pavement subgrade.
If, at the time of excavation, it is not possible to place this material in its final location, it shall be stockpiled
in approved areas until it can be placed. The more suitable material shall then be placed and compacted as
specified. Selective grading shall be considered incidental to the work involved. The cost of stockpiling and
placing the material shall be included in the various pay items of work involved.

b. Undercutting. Rock, shale, hardpan, loose rock, boulders, or other material unsatisfactory for
safety areas, subgrades, roads, shoulders, or any areas intended for turf shall be excavated to a minimum
depth of 12 inches below the subgrade or to the depth specified by the RPR. Muck, peat, matted roots, or
other yielding material, unsatisfactory for subgrade foundation, shall be removed to the depth specified.
Unsuitable materials shall be disposed off the airport. The cost is incidental to this item. This excavated
material shall be paid for at the contract unit price per cubic yard for unsuitable excavation. The excavated
area shall be backfilled with suitable material obtained from the grading operations or borrow areas and
compacted to specified densities. The necessary backfill will constitute a part of the embankment. Where
rock cuts are made, backfill with select material. Any pockets created in the rock surface shall be drained in
accordance with the details shown on the plans. Undercutting will be paid as unclassified excavation.
c. Over-break. Over-break, including slides, is that portion of any material displaced or loosened
beyond the finished work as planned or authorized by the RPR. All over-break shall be graded or removed
by the Contractor and disposed of as directed by the RPR. The RPR shall determine if the displacement of
such material was unavoidable and their own decision shall be final. Payment will not be made for the
removal and disposal of over-break that the RPR determines as avoidable. Unavoidable over-break will be
classified as “Unclassified Excavation.”
d. Removal of utilities. The removal of existing structures and utilities required to permit the
orderly progress of work will be accomplished by the Contractor as indicated on the plans. All existing
foundations shall be excavated at least 2 feet below the top of subgrade or as indicated on the plans, and the
material disposed of as directed by the RPR. All foundations thus excavated shall be backfilled with suitable
material and compacted as specified for embankment or as shown on the plans.
e. Unsuitable Excavation and Replacement, Backfill and Compaction. If zones of
soft, wet or unstable subgrade are found during site grading and proof rolling, the Contractor shall remove
the unstable soils to a minimum depth of 12 inches below the finished subgrade, or more, depending on the
severity of the problem area. The area shall be backfilled and compacted in accordance with 152-2.10 with
crushed aggregate base course material meeting the requirements of Technical Specification P-209. Asphalt
millings may be used for backfill, however, it will be necessary for the Contractor to demonstrate that the
material can reach an acceptable compaction level as tested with a sand cone or nuclear density gauge. The
work shall only be performed with advance approval of the RPR after the RPR concurs with the Contractor’s
proposed method. All hauling, work, equipment and material required shall be considered incidental to
“Unsuitable Excavation and Replacement, Backfill and Compaction”.
152-2.3 Borrow excavation. Borrow areas are not required.
152-2.4 Drainage excavation. Drainage excavation shall consist of excavating drainage ditches
including intercepting, inlet, or outlet ditches; or other types as shown on the plans. The work shall be
performed in sequence with the other construction. Ditches shall be constructed prior to starting adjacent
excavation operations. All satisfactory material shall be placed in embankment fills; unsuitable material
shall be placed in designated waste areas or as directed by the RPR. All necessary work shall be performed
true to final line, elevation, and cross-section. The Contractor shall maintain ditches constructed on the
project to the required cross-section and shall keep them free of debris or obstructions until the project is
accepted.
152-2.5 Preparation of cut areas or areas where existing pavement has been
removed. In those areas on which a subbase or base course is to be placed, the top 12 inches of subgrade

shall be scarified, moisture conditioned to optimum (3% below to 1% above) and compacted to not less than
95% of maximum density for non-cohesive soils, and 95% of maximum density for cohesive soils as
determined by ASTM D698. As used in this specification, "non-cohesive" shall mean those soils having a
plasticity index (PI) of less than 3 as determined by ASTM D4318.
152-2.6 Preparation of embankment area. All sod and vegetative matter shall be removed from
the surface upon which the embankment is to be placed. The cleared surface shall be broken up by plowing
or scarifying to a minimum depth of 6 inches and shall then be compacted per paragraph 152-2.10.
Sloped surfaces steeper than one (1) vertical to four (4) horizontal shall be plowed, stepped, benched, or
broken up so that the fill material will bond with the existing material. When the subgrade is part fill and
part excavation or natural ground, the excavated or natural ground portion shall be scarified to a depth of
12 inches and compacted as specified for the adjacent fill.
No direct payment shall be made for the work performed under this section. The necessary clearing and
grubbing and the quantity of excavation removed will be paid for under the respective items of work.
152-2.7 Control Strip. The first half-day of construction of subgrade and/or embankment shall be
considered as a control strip for the Contractor to demonstrate, in the presence of the RPR, that the
materials, equipment, and construction processes meet the requirements of this specification. The sequence
and manner of rolling necessary to obtain specified density requirements shall be determined. The
maximum compacted thickness may be increased to a maximum of 12 inches upon the Contractor’s
demonstration that approved equipment and operations will uniformly compact the lift to the specified
density. The RPR must witness this demonstration and approve the lift thickness prior to full production.
Control strips that do not meet specification requirements shall be reworked, re-compacted, or removed
and replaced at the Contractor’s expense. Full operations shall not begin until the control strip has been
accepted by the RPR. The Contractor shall use the same equipment, materials, and construction methods
for the remainder of construction, unless adjustments made by the Contractor are approved in advance by
the RPR.
152-2.8 Formation of embankments. The material shall be constructed in lifts as established in
the control strip, but not less than 6 inches nor more than 12 inches of compacted thickness.
When more than one lift is required to establish the layer thickness shown on the plans, the construction
procedure described here shall apply to each lift. No lift shall be covered by subsequent lifts until tests verify
that compaction requirements have been met. The Contractor shall rework, re-compact and retest any

The material in each lift shall be within ±2% of optimum moisture content before rolling to obtain the
prescribed compaction. The material shall be moistened or aerated as necessary to achieve a uniform
moisture content throughout the lift. Natural drying may be accelerated by blending in dry material or
manipulation alone to increase the rate of evaporation.
The Contractor shall make the necessary corrections and adjustments in methods, materials or moisture
content to achieve the specified embankment density.
The Contractor’s laboratory will take samples of excavated materials which will be used in embankment for
testing and develop a Moisture-Density Relations of Soils Report (Proctor) in accordance with ASTM D698.
A new Proctor shall be developed for each soil type based on visual classification.
The Contractor’s laboratory shall perform density tests for every 3,000 square yards of compacted
embankment for each lift which is required to be compacted, or other appropriate frequencies as
determined by the RPR.
If the material has greater than 30% retained on the 3/4-inch sieve, follow AASHTO T-180 Annex
Correction of maximum dry density and optimum moisture for oversized particles.
Rolling operations shall be continued until the embankment is compacted to not less than 95% of maximum
density for non-cohesive soils, and 95% of maximum density for cohesive soils as determined by ASTM
D698. Under all areas to be paved, the embankments shall be compacted to a depth of 12-inches and to a
density of not less than 95% of the maximum density as determined by ASTM D698. As used in this
specification, "non-cohesive" shall mean those soils having a plasticity index (PI) of less than 3 as
determined by ASTM D4318.
On all areas outside of the pavement areas, no compaction will be required on the top 4 inches which shall
be prepared for a seedbed in accordance with Item T-901.
The in-place field density shall be determined in accordance with ASTM 6938 using Procedure A, the direct
transmission method, and ASTM D6938 shall be used to determine the moisture content of the material.
The machine shall be calibrated in accordance with ASTM D6938. The Contractor’s laboratory shall
perform all density tests in the RPR’s presence and provide the test results upon completion to the RPR for
acceptance. If the specified density is not attained, the area represented by the test or as designated by the
RPR shall be reworked and/or re-compacted and additional random tests made. This procedure shall be
followed until the specified density is reached.
Compaction areas shall be kept separate, and no lift shall be covered by another lift until the proper density
is obtained.
During construction of the embankment, the Contractor shall route all construction equipment evenly over
the entire width of the embankment as each lift is placed. Lift placement shall begin in the deepest portion
of the embankment fill. As placement progresses, the lifts shall be constructed approximately parallel to the
finished pavement grade line.
When rock, concrete pavement, asphalt pavement, and other embankment material are excavated at
approximately the same time as the subgrade, the material shall be incorporated into the outer portion of

the embankment and the subgrade material shall be incorporated under the future paved areas. Stones,
fragmentary rock, and recycled pavement larger than 4 inches in their greatest dimensions will not be
allowed in the top 12 inches of the subgrade. Rockfill shall be brought up in lifts as specified or as directed
by the RPR and the finer material shall be used to fill the voids forming a dense, compact mass. Rock,
cement concrete pavement, asphalt pavement, and other embankment material shall not be disposed of
except at places and in the manner designated on the plans or by the RPR.
When the excavated material consists predominantly of rock fragments of such size that the material cannot
be placed in lifts of the prescribed thickness without crushing, pulverizing or further breaking down the
pieces, such material may be placed in the embankment as directed in lifts not exceeding 2 feet in thickness.
Each lift shall be leveled and smoothed with suitable equipment by distribution of spalls and finer fragments
of rock. The lift shall not be constructed above an elevation 4 feet below the finished subgrade.
There will be no separate measurement of payment for compacted embankment. All costs incidental to
placing in lifts, compacting, discing, watering, mixing, sloping, and other operations necessary for
construction of embankments will be included in the contract price for excavation, borrow, or other items.
152-2.9 Proof rolling. The purpose of proof rolling the subgrade is to identify any weak areas in the
subgrade and not for compaction of the subgrade. Before start of embankment, and after compaction is
completed, the subgrade area shall be proof rolled with a 20-ton Tandem axle Dual Wheel Dump Truck
loaded to the legal limit with tires inflated to 100 psi in the presence of the RPR. Apply a minimum of 3
coverages, or as specified by the RPR, under pavement areas. A coverage is defined as the application of one
tire print over the designated area. Soft areas of subgrade that deflect more than 1 inch or show permanent
deformation greater than 1 inch shall be removed and replaced with suitable material or reworked to
conform to the moisture content and compaction requirements in accordance with these specifications.
Removal and replacement of soft areas is incidental to this item.
152-2.10 Compaction requirements. The subgrade under areas to be paved shall be compacted to
a depth of 12 inches and to a density of not less than 95% of the maximum dry density as determined by
ASTM D698. The subgrade in areas outside the limits of the pavement areas shall be compacted to a depth
of 4 inches and to a density of not less than 95% of the maximum density as determined by ASTM D698.
The material to be compacted shall be within -3% and +1% of optimum moisture content before being rolled
to obtain the prescribed compaction (except for expansive soils). When the material has greater than 30
percent retained on the ¾ inch sieve, follow the methods in ASTM D698. Tests for moisture content and
compaction will be taken at a minimum of 3,000 square yards of subgrade. All quality assurance testing
shall be done by the Contractor’s laboratory in the presence of the RPR, and density test results shall be
furnished upon completion to the RPR for acceptance determination.
The in-place field density shall be determined in accordance with ASTM D6938 using Procedure A, the
direct transmission method, and ASTM D6938 shall be used to determine the moisture content of the
material. The machine shall be calibrated in accordance with ASTM D6938 within 12 months prior to its
use on this contract. The gage shall be field standardized daily.
Maximum density refers to maximum dry density at optimum moisture content unless otherwise specified.
If the specified density is not attained, the entire lot shall be reworked and/or re-compacted and additional
random tests made. This procedure shall be followed until the specified density is reached.

608-3.2 Control areas and control strips. Prior to full application, the control strip must be
accepted by the RPR. The surface preparation, personnel, equipment, and method of operation used on the
test area(s) and control strip(s) shall be the same as used on the remainder of the work.
A qualified manufacturer’s representative shall be present in the field to assist the Contractor in applying
control areas and/or control strips to determine the appropriate application rate of both emulsion and
aggregate to be approved by the RPR.
A test area(s) and control strip(s) shall be applied for each differing asphalt pavement surface identified in
the project. The test area(s) and control strip(s) shall be used to determine the material application rate(s)
of both emulsion and sand prior to full production.
a. For taxiway, taxilane and apron surfaces. Prior to full application, the Contractor shall
place test areas at varying application rates as recommended by the Contractor’s manufacturer’s
representative to determine appropriate application rate(s). The test areas will be located on representative
section(s) of the pavement to receive the asphalt surface treatment designated by the RPR.
b. For runway and high-speed exit taxiway surfaces. Prior to full application, the
Contractor shall place a series of control strips a minimum of 300 feet long by 12 feet wide, or width of
anticipated application, whichever is greater, at varying application rates as recommended by the
manufacturer’s representative and acceptable to the RPR to determine appropriate application rate(s). The
control strips should be separated by a minimum of 200 feet between control strips. The area to be tested
will be located on a representative section of the pavement to receive the asphalt surface treatment
designated by the RPR. The control strips should be placed under similar field conditions as anticipated for
the actual application. The skid resistance of the existing pavement shall be determined for each control
strip with a continuous friction measuring equipment (CFME). The skid resistance of existing pavement
can be immediately adjacent to the control strip or at the same location as the control strip if testing prior
to application. The Contractor may begin testing the skid resistance of runway and high-speed exit taxiway
control strips after application of the asphalt surface treatment has fully cured, generally 8 to 36 hours after
application of the control strips depending on site and environmental conditions. Aircraft shall not be
permitted on the runway or high-speed exit taxiway control strips until such time as the Contractor validates
that its surface friction meets the maintenance planning friction levels in AC 150/5320-12, Table 3-2 when
tested at speeds of 40 and 60 mph wet with approved CFME.
If the control strip should prove to be unsatisfactory, necessary adjustments to the application rate,
placement operations, and equipment shall be made. Additional control strips shall be placed and
additional skid resistance tests performed and evaluated. Full production shall not begin without the RPR’s
approval of an appropriate application rate(s). Acceptable control strips shall be paid for in accordance with
paragraph 608-8.1.

CONSTRUCTION METHODS
608-4.1 Worker safety. The Contractor shall obtain a Safety Data Sheet (SDS) for both the asphalt
emulsion product and sand and require workmen to follow the manufacturer’s recommended safety
precautions.
608-4.2 Weather limitations. The asphalt emulsion shall be applied only when the existing
pavement surface is dry and when the weather is not foggy, rainy, or when the wind velocity will prevent
the uniform application of the material. No material shall be applied in strong winds that interfere with the
uniform application of the material(s), or when dust or sand is blowing or when rain is anticipated within
eight (8) hours of application completion. The atmospheric temperature and the pavement surface
temperature shall both be at, or above 60°F and rising. Seal coat shall not be applied when pavement
temperatures are expected to exceed 130ºF within the subsequent 72 hours if traffic will be opened on
pavement within those 72 hours. During application, account for wind drift. Cover existing buildings,
structures, runway edge lights, taxiway edge lights, informational signs, retro-reflective marking and in-
pavement duct markers as necessary to protect against overspray before applying the emulsion. Should
emulsion get on any light or marker fixture, promptly clean the fixture. If cleaning is not satisfactory to the
RPR, the Contractor shall replace any light, sign or marker with equivalent equipment at no cost to the
Owner.
608-4.3 Equipment and tools. The Contractor shall furnish all equipment, tools, and machinery necessary
for the performance of the work.
a. Pressure distributor. The emulsion shall be applied with a manufacturer-approved computer
rate-controlled asphalt distributor. The equipment shall be in good working order and contain no
contaminants or diluents in the tank. Spray bar tips must be clean, free of burrs, and of a size to maintain
an even distribution of the emulsion. Any type of tip or pressure source is suitable that will maintain
predetermined flow rates and constant pressure during the application process with application speeds
under eight (8) mph or 700 feet per minute. The equipment will be tested under pressure for leaks and to
ensure proper set-up before use. The Contractor will provide verification of truck set-up (via a test-shot
area), including but not limited to, nozzle tip size appropriate for application per nozzle manufacturer,
spray-bar height and pressure and pump speed appropriate for the viscosity and temperature of sealer
material, evidence of triple-overlap spray pattern, lack of leaks, and any other factors relevant to ensure the
truck is in good working order before use.
The distributor truck shall be equipped with a 12-foot, minimum, spray bar with individual nozzle
control. The distributor truck shall be capable of specific application rates in the range of 0.05 to 0.25
gallons per square yard. These rates shall be computer-controlled rather than mechanical. The distributor
truck shall have an easily accessible thermometer that constantly monitors the temperature of the emulsion,
and have an operable mechanical tank gauge that can be used to cross-check the computer accuracy.
The distributor truck shall effectively heat and mix the material to the required temperature prior to
application in accordance with the manufacturer’s recommendations.
The distributor shall be equipped with a hand sprayer to spray the emulsion in areas not accessible to
the distributor truck.

b. Aggregate spreader. The asphalt distributor truck will be equipped with an aggregate
spreader mounted to the distributor truck that can apply sand to the emulsion in a single pass operation
without driving through wet emulsion. The aggregate spreader shall be equipped with a variable control
system capable of uniformly distributing the sand at the specified rate at varying application widths and
speeds. The aggregate spreader must be adjusted to produce an even and accurate application of specified
aggregate. Prior to any seal coat application, the aggregate spreader will be calibrated onsite to ensure
acceptable uniformity of spread. The RPR will observe the calibration and verify the results. The aggregate
spreader will be re-calibrated each time the aggregate rate is changed either during the application of test
strips or production. The Contractor may consult the seal coat manufacturer representative for procedure
and guidance. The sander shall have a minimum hopper capacity of 3,000 pounds of sand. Push-type hand
sanders will be allowed for use around lights, signs and other obstructions, if necessary.
c. Power broom/blower. A power broom and/or blower shall be provided for removing loose
material from the surface to be treated.
d. Equipment calibration. Asphalt distributors must be calibrated within the same construction

never add asphalt material concentrate to heated water. Mix one part heated water to two parts asphalt
material concentrate, by volume.
Add 1% polymer, by volume, to the emulsion mix. If the polymer is added to the emulsion mix at the plant,
submit weight scale tickets to the RPR. As an option, the polymer may be added to the emulsion mix at the
job site provided the polymer is added slowly while the asphalt distributor truck circulating pump is
running. The mix must be agitated for a minimum of 15 minutes or until the polymer is mixed to the
satisfaction of the RPR.
608-4.6 Application of asphalt emulsion. The asphalt emulsion shall be applied using a pressure
distributor upon the properly prepared, clean and dry surface at the application rate recommended by the
manufacturer’s representative and approved by the RPR from the test area/sections evaluation for each
designated treatment area. The asphalt emulsion should be applied at a temperature between 130°F and
160°F or in accordance with the manufacturer’s recommendation.
If low spots and depressions greater than 1/2 inch in depth in the pavement surface cause ponding or
puddling of the applied materials, the pavement surface shall be lightly broomed with a broom or brush
type squeegee until the pavement surface is free of any pools of excess material.
During all applications, the surfaces of adjacent structures shall be protected to prevent their being
spattered or marred.

901-2.4 Soil for repairs. The soil for fill and topsoiling of areas to be repaired shall be at least of equal
quality to that which exists in areas adjacent to the area to be repaired. The soil shall be relatively free from
large stones, roots, stumps, or other materials that will interfere with subsequent sowing of seed,
compacting, and establishing turf, and shall be approved by the RPR before being placed.
CONSTRUCTION METHODS
901-3.1 Advance preparation and cleanup. After grading of areas has been completed and before
applying fertilizer and ground limestone, areas to be seeded shall be raked or otherwise cleared of stones
larger than 2 inches in any diameter, sticks, stumps, and other debris that might interfere with sowing of
seed, growth of grasses, or subsequent maintenance of grass-covered areas. If any damage by erosion or
other causes has occurred after the completion of grading and before beginning the application of fertilizer
and ground limestone, the Contractor shall repair such damage include filling gullies, smoothing
irregularities, and repairing other incidental damage.
An area to be seeded shall be considered a satisfactory seedbed without additional treatment if it has
recently been thoroughly loosened and worked to a depth of not less than 5 inches as a result of grading
operations and, if immediately prior to seeding, the top 3 inches of soil is loose, friable, reasonably free from
large clods, rocks, large roots, or other undesirable matter, and if shaped to the required grade.
When the area to be seeded is sparsely sodded, weedy, barren and unworked, or packed and hard, any grass
and weeds shall first be cut or otherwise satisfactorily disposed of, and the soil then scarified or otherwise
loosened to a depth not less than 5 inches. Clods shall be broken and the top 3 inches of soil shall be worked
into a satisfactory seedbed by discing, or by use of cultipackers, rollers, drags, harrows, or other appropriate
means.

Seeds of legumes, either alone or in mixtures, shall be inoculated before mixing or sowing, in accordance
with the instructions of the manufacturer of the inoculant. When seeding is required at other than the
seasons shown on the plans or in the special provisions, a cover crop shall be sown by the same methods
required for grass and legume seeding.
All seed is to be drilled one-quarter (¼) inch to one-half (½) inch into the soil at the rate of application
specified in Table 1 with a mechanical, power-drawn drill seeder. Rows shall be spaced not more than seven
(7) inches apart. Contractor shall drill one-half (½) of the required rate of application in one compass
direction, and then drill the remaining half of the required rate of application in a direction ninety degrees
(90°) to the first half. Drill must be specifically designed to accommodate variability in size and physical
characteristics of native rangeland grass seeds. Drill seed hopper shall have an auger to mix seed while
drilling. Seed that is extremely small shall be sowed from a separate hopper adjusted to the proper rate of
application.
d. Rolling. After the seed has been properly covered, the seedbed shall be immediately compacted
by means of an approved lawn roller, weighing 40 to 65 pounds per foot of width for clay soil (or any soil
having a tendency to pack), and weighing 150 to 200 pounds per foot of width for sandy or light soils.
901-3.3 Wet application method.
a. General. The Contractor may elect to apply seed and fertilizer (and lime, if required) by spraying
them on the previously prepared seedbed in the form of an aqueous mixture and by using the methods and
equipment described herein. The rates of application shall be as specified in the special provisions.
b. Spraying equipment. The spraying equipment shall have a container or water tank equipped
with a liquid level gauge calibrated to read in increments not larger than 50 gallons over the entire range of

In order to reach areas inaccessible to the regular equipment, an extension hose at least 50 feet in length
shall be provided to which the nozzles may be connected.
c. Mixtures. Lime, if required, shall be applied separately, in the quantity specified, prior to the
fertilizing and seeding operations. Not more than 220 pounds of lime shall be added to and mixed with each
100 gallons of water. Seed and fertilizer shall be mixed together in the relative proportions specified, but
not more than a total of 220 pounds of these combined solids shall be added to and mixed with each 100
gallons of water.
All water used shall be obtained from fresh water sources and shall be free from injurious chemicals
and other toxic substances harmful to plant life. The Contractor shall identify to the RPR all sources of water
at least two (2) weeks prior to use. The RPR may take samples of the water at the source or from the tank
at any time and have a laboratory test the samples for chemical and saline content. The Contractor shall not
use any water from any source that is disapproved by the RPR following such tests.
All mixtures shall be constantly agitated from the time they are mixed until they are finally applied to
the seedbed. All such mixtures shall be used within two (2) hours from the time they were mixed or they
shall be wasted and disposed of at approved locations.
d. Spraying. Lime, if required, shall be sprayed only upon previously prepared seedbeds. After the
applied lime mixture has dried, the lime shall be worked into the top 3 inches, after which the seedbed shall
again be properly graded and dressed to a smooth finish.
Mixtures of seed and fertilizer shall only be sprayed upon previously prepared seedbeds on which the
lime, if required, shall already have been worked in. The mixtures shall be applied by means of a high-
pressure spray that shall always be directed upward into the air so that the mixtures will fall to the ground
like rain in a uniform spray. Nozzles or sprays shall never be directed toward the ground in such a manner
as might produce erosion or runoff.
Particular care shall be exercised to ensure that the application is made uniformly and at the prescribed
rate and to guard against misses and overlapped areas. Proper predetermined quantities of the mixture in
accordance with specifications shall be used to cover specified sections of known area.
Checks on the rate and uniformity of application may be made by observing the degree of wetting of the
ground or by distributing test sheets of paper or pans over the area at intervals and observing the quantity
of material deposited thereon.

Seeding
On surfaces that are to be mulched as indicated by the plans or designated by the RPR, seed and
fertilizer applied by the spray method need not be raked into the soil or rolled. However, on surfaces on
which mulch is not to be used, the raking and rolling operations will be required after the soil has dried.
901-3.4 Maintenance of seeded areas. The Contractor shall protect seeded areas against traffic
or other use by warning signs or barricades, as approved by the RPR. Surfaces gullied or otherwise damaged
following seeding shall be repaired by regrading and reseeding as directed. The Contractor shall mow, water
as directed, and otherwise maintain seeded areas in a satisfactory condition until final inspection and
acceptance of the work.
When either the dry or wet application method outlined above is used for work done out of season, it will
be required that the Contractor establish a good stand of grass of uniform color and density to the
satisfaction of the RPR. A grass stand shall be considered adequate when bare spots are one square foot or
less, randomly dispersed, and do not exceed 3% of the area seeded.

COORDINATION
1.1
General Project Information
This project is located at Chandler Municipal Airport (Airport or CHD). The project includes construction
of grading and paving improvements intended to promote drainage away from the hangar structures in the
Central Hangar Complex.
This Construction Safety and Phasing Plan (CSPP) provides specific information to the Contractor and/or
Subcontractors contracted to carry out the construction contract for this project. This plan includes the
requirements and procedures for accident prevention, safety requirements, and security considerations at
CHD. The Airport’s safety objective is to achieve accident-free construction projects. Furthermore, the
Contractor must be in full compliance with FAA Advisory Circular (AC) 150/5370-2G: Operational Safety
on Airports During Construction. The CSPP and project safety and phasing requirements will be discussed
in detail at the Pre-Bid and Pre-Construction Conferences. The Contractor is required to submit a Safety
Plan Compliance Document (SPCD) to CHD describing how the contractor will comply with the
requirements set forth in the CSPP.
The Contractor or Subcontractor shall conduct their operations in a manner that will provide safe working
conditions for all employees, and the protection of the public and all others who may be affected by
construction activities. Nothing contained in this plan is intended to relieve the Contractor, Subcontractor
or suppliers of the obligations assumed by the Contractor under contract with the Airport or as required by
law.
Safety must be an integral part of the job. Full participation, cooperation, and support are necessary to
ensure the safety and health of all persons and property involved in the project. The purpose of phasing,
marking, barricading, and lighting of airside construction areas is to delineate hazardous areas and prevent
unauthorized incursions into the areas by personnel, vehicles, equipment, and aircraft during construction;
and to positively separate construction activity from aircraft operations.
A Pre-Bid Conference will be scheduled during the bidding process to allow prospective bidders an
opportunity to understand the safety aspects of this project. A key topic of this meeting will include a
detailed review of this CSPP, with emphasis on Contractor responsibilities for safety, as well as access and
work areas in each phase.
A Pre-Construction Conference will be scheduled prior to the issuance of the Notice to Proceed. Invitees
and attendees will include City and Airport staff; the Engineer-of-Record; the RPR; the Contractor’s Project
Manager/Superintendent; and representatives from the Air Traffic Control Tower (ATCT). Relevant safety-
related issues will be discussed in detail at this meeting.
Topics of discussion will include the FAA Advisory Circular (AC) 150/5370-2G: Operational Safety on
Airports During Construction; project scope; the RPR’s responsibility; identifying the Contractor’s
Superintendent; NOTAM responsibility; phasing and scheduling of work; Notice to Proceed date; safety
during construction; security, badging and escorting requirements; quality control and testing; test reports;
maintenance of record drawings; and other contract and Federal requirements.
The Contractor is required to submit an overall project schedule at the Pre-Construction Conference which
will allow Airport staff, the Engineer and the Contractor to identify affected areas during construction.

minimum, it should address requirements for the securing of clothing and hardhats, as well as any
requirements for hearing protection.
3.1.5
Utilities for Firefighting
There are multiple fire hydrants located in the project area, however, these will be protected in place and
no impact to water distribution is anticipated. While every effort has been made to include the locations
and depths of known utilities within the project area, the Contractor will be required to pothole for utilities
to avoid damage to them.
3.1.6
Affected Approach and Departure Surfaces
The Contractor will be required to abide by the Part 77 airspace requirements at all times, including all
equipment, material and batch plants that may be required for this project. Construction equipment will be
limited to stay below the approach surfaces at all times. Equipment along the haul route having a height of

deviate from the marked haul route. Additionally, during times of low visibility or darkness, the drivers
shall be required to use a flashing amber beacon.
3.2.2
Temporary Taxi Operations
Temporary taxi operations and alternate routes to accommodate aircraft movement needs are discussed for
each project phase in Section 2 Phasing.
3.2.3
Detours for ARFF and Other Airport Vehicles
The Airport is not equipped with an ARFF facility; however, in the event of an emergency, ARFF and other
airport vehicles are not anticipated to be hindered by construction activities related to this project.
However, because each construction situation is different, the Contractor must coordinate construction
vehicle traffic with the Airport Operations for each phase of construction. Contractor vehicle movements to
and from the site must conform to approved Access and Haul Roads or as directed by the Airport at the
weekly construction meetings. The Airport will coordinate with all stakeholders any detours from existing
Airfield Service Roads as needed, throughout the duration of the project.
3.2.4
Maintenance of Essential Utilities
Essential utilities are not anticipated to be impacted in this project. The Contractor will be required to
provide temporary means to any impacted utilities until the impacted utilities are restored.
3.2.5
Temporary ATC Procedures
The Air Traffic Control Tower (ATCT) will be kept informed of all construction activities throughout the
duration of the project. The Contractor will provide construction schedules at least three weeks ahead of
the proposed construction activities to be given to the ATCT by the Airport Operations Superintendent. The
ATCT will be expected to provide feedback about any concerns that the ATCT has for construction areas
and Contractor movements. Project phasing plans will be provided to the ATCT so that they are aware of
the impacts to aircraft operations on the ground and in the air.
While the Airport will ultimately be responsible for issuing NOTAMs related to construction activities and
restrictions, the ATCT will be responsible for redirecting pilots from proceeding into construction areas.

through Operations.
•
After Operations notifies electricians of closures, the Airport electricians will turn off the closed
runways/taxiways using the airfield computer system.
•
The Contractor will supply an approved breaker-locking device and lock, then lock off the individual
breakers for the circuits to be locked out. These items will remain in the vault in a lock box provided
by Airport.
•
The load break elbows and/or S-1 switches will be pulled, locked on the corresponding regulator by
the Electrical Contractor, and the S-1 cabinet will be locked by the Contractor.
•
The Electrical Contractor and the Airport electricians must fill out lock-out/tag-out forms before
leaving the Vault.
•
Upon completion of the lock-out, the Contractor will remove all locks and install the load breaks
and/or S-1 switches. All circuits must be verified operational in the manual mode on the regulator.
Operations will perform a complete check of the lights in the field to verify actual operation.
•
When that has been completed, the Airport electricians will notify the Airport Operations when
lock-in is complete and regulators are in active control; Operations will notify the ATCT that they
have control of the airfield lighting.
•
Complete lock-out/lock-in forms.

COORDINATION
1.1
General Project Information
This project is located at Chandler Municipal Airport (Airport or CHD). The project includes construction
of grading and paving improvements intended to promote drainage away from the hangar structures in the
Central Hangar Complex.
This Construction Safety and Phasing Plan (CSPP) provides specific information to the Contractor and/or
Subcontractors contracted to carry out the construction contract for this project. This plan includes the
requirements and procedures for accident prevention, safety requirements, and security considerations at
CHD. The Airport’s safety objective is to achieve accident-free construction projects. Furthermore, the
Contractor must be in full compliance with FAA Advisory Circular (AC) 150/5370-2G: Operational Safety
on Airports During Construction. The CSPP and project safety and phasing requirements will be discussed
in detail at the Pre-Bid and Pre-Construction Conferences. The Contractor is required to submit a Safety
Plan Compliance Document (SPCD) to CHD describing how the contractor will comply with the
requirements set forth in the CSPP.
The Contractor or Subcontractor shall conduct their operations in a manner that will provide safe working
conditions for all employees, and the protection of the public and all others who may be affected by
construction activities. Nothing contained in this plan is intended to relieve the Contractor, Subcontractor
or suppliers of the obligations assumed by the Contractor under contract with the Airport or as required by
law.
Safety must be an integral part of the job. Full participation, cooperation, and support are necessary to
ensure the safety and health of all persons and property involved in the project. The purpose of phasing,
marking, barricading, and lighting of airside construction areas is to delineate hazardous areas and prevent
unauthorized incursions into the areas by personnel, vehicles, equipment, and aircraft during construction;
and to positively separate construction activity from aircraft operations.
A Pre-Bid Conference will be scheduled during the bidding process to allow prospective bidders an
opportunity to understand the safety aspects of this project. A key topic of this meeting will include a
detailed review of this CSPP, with emphasis on Contractor responsibilities for safety, as well as access and
work areas in each phase.
A Pre-Construction Conference will be scheduled prior to the issuance of the Notice to Proceed. Invitees
and attendees will include City and Airport staff; the Engineer-of-Record; the RPR; the Contractor’s Project
Manager/Superintendent; and representatives from the Air Traffic Control Tower (ATCT). Relevant safety-
related issues will be discussed in detail at this meeting.
Topics of discussion will include the FAA Advisory Circular (AC) 150/5370-2G: Operational Safety on
Airports During Construction; project scope; the RPR’s responsibility; identifying the Contractor’s
Superintendent; NOTAM responsibility; phasing and scheduling of work; Notice to Proceed date; safety
during construction; security, badging and escorting requirements; quality control and testing; test reports;
maintenance of record drawings; and other contract and Federal requirements.
The Contractor is required to submit an overall project schedule at the Pre-Construction Conference which
will allow Airport staff, the Engineer and the Contractor to identify affected areas during construction.

•
Provide a sweeper truck and/or vacuum truck and clean the taxiway pavement in the vicinity of the
work areas;
•
Temporarily safe-up the graded/infield areas such that there are no humps, ruts, depressions,
equipment, tools, or other materials within the TSA;
•
Ensure that any excavation within the TSA is filled and compacted;
•
Perform a FOD/safety walk of the taxiway pavement and the adjacent graded/infield areas with
construction inspection and Airport staff to ensure compliance with these procedures;
•
Remove the low-profile barricades from the applicable taxiways;
•
Perform any additional necessary actions as a result of the FOD/safety walk as required by the
construction inspection and/or Airport staff.
•
Remove any barricades used for the temporary nightly closure.
17.4.2 Appropriate Covering of Excavations Within TSA’s
Any excavation within any TSA shall be filled and compacted prior to reopening a taxiway.
17.4.3 Marking of Excavations and Open Trenches
Hazards, such as open trenches, major excavations, manholes, and steep embankments shall be barricaded,
lighted, and outlined with appropriate caution tape or orange fabric construction fencing to prohibit
accidental falls. The Contractor’s site-specific and company safety plan/guidelines shall address the
protection of these areas and the protection of the employees against these hazards. See Section 16 Hazard
Marking & Lighting for further information.
17.4.4 Maintenance of TSA’s
The Contractor will be required to maintain the TSA while work is being performed in the area. Upon
completion of work within the TSA, the Contractor will be required to leave the area in accordance with TSA
standards, or as identified in the plans.
17.5
Taxiway Object Free Area (TOFA)
Any taxiway having construction within its Object Free Area will be closed during construction
duration/hours. No equipment or tools will be left unattended within the TOFA as the Contractor will be
required to move these items to the staging and storage area when not in use. See Section 17.4 Taxiway
Safety Area (TSA) for further information.
17.6
Runway Approach & Departure Surfaces
It is not anticipated that any construction of this project will impact a Runway Approach or Departure
Surface or Clearway.

CHD Hangar Area Pavement Reconstruction
Final Construction Safety & Phasing Plan
18.1.2 Use of Electrical Blasting Caps
The use of electrical blasting caps is not permitted within 1,000-ft of the Airport property.
18.2
Restrictions
18.2.1 Tall Equipment
The use of tall equipment is not permitted unless a 7460-1 determination letter is issued.
18.2.2 Open Flame Welding and Torches
Open flame welding and the use of torches shall be approved by the Airport prior to the project
commencing. If this type of work is required on this project, the Contractor shall notify the Airport at least
48 hours in advance of the work.
18.2.3 Airfield Lighting Vault Lock-Out/Tag-Out Policy
Prior to opening any electrical pull box or light cans, the appropriate circuits will be tagged and locked out
at the vault room in accordance with OSHA requirements. A pre-event meeting shall be held on site at least
48 hours in advance of the work with the Contractor, the Airport, and the RPR to review the work
undertaken, to familiarize all parties with the existing system and controls that will shut down and re-
started, and to confirm lock-out/tag-out procedures used. The Contractor shall provide multi-position hasp
and both the Contractor and the Airport will attach their own separate locks. No system shall be energized
until such time that both parties have removed their locks, indicating a safe situation to energize. The
system will be checked for functionality by the Contractor in the presence of a CHD staff member before
leaving the project site.
The purpose of this procedure is to standardize the lock-out/tag-out procedures between Electrical
Contractors, Airport Electricians, Operations, and the Air Traffic Control Tower. This procedural checklist
must be followed to the letter:
•
The Airport electricians responding to a lock-out/tag-out request will coordinate with the ATCT
through Operations.
•
After Operations notifies electricians of closures, the Airport electricians will turn off the closed
runways/taxiways using the airfield computer system.
•
The Contractor will supply an approved breaker-locking device and lock, then lock off the individual
breakers for the circuits to be locked out. These items will remain in the vault in a lock box provided
by Airport.
•
The load break elbows and/or S-1 switches will be pulled, locked on the corresponding regulator by
the Electrical Contractor, and the S-1 cabinet will be locked by the Contractor.
•
The Electrical Contractor and the Airport electricians must fill out lock-out/tag-out forms before
leaving the Vault.
•
Upon completion of the lock-out, the Contractor will remove all locks and install the load breaks
and/or S-1 switches. All circuits must be verified operational in the manual mode on the regulator.
Operations will perform a complete check of the lights in the field to verify actual operation.
•
When that has been completed, the Airport electricians will notify the Airport Operations when
lock-in is complete and regulators are in active control; Operations will notify the ATCT that they
have control of the airfield lighting.
•
Complete lock-out/lock-in forms.

Action Required (Describe)
No Action
Required
(Check)
Excavation adjacent to runways, taxiways,
and aprons improperly backfilled.
Mounds of earth, construction materials,
temporary structures, and other obstacles
near any open runway, taxiway, or taxi lane;
in the related Object Free area and aircraft
approach or departure areas/zones; or
obstructing any sign or marking.
Heavy equipment (stationary or mobile)
operating or idle near AOA, in runway
approaches and departures areas, or in OFZ.
Equipment or material near NAVAIDs that
may degrade or impair radiated signals
and/or the monitoring of navigation and
visual aids. Unauthorized or improper vehicle
operations in localizer or glide slope critical
areas, resulting in electronic interference
and/or facility shutdown.
Tall and especially relatively low visibility
units (that is, equipment with slim profiles) —
cranes, drills, and similar objects — located
in critical areas, such as OFZ and approach
zones.
Improperly positioned or malfunctioning
lights or unlighted airport hazards, such as
holes or excavations, on any apron, open
taxiway, or open taxi lane or in a related
safety, approach, or departure area.
Obstacles, loose pavement, trash, and other
debris on or near AOA. Construction debris
(gravel, sand, mud, paving materials) on
airport pavements may result in aircraft
propeller, turbine engine, or tire damage.
Also, loose materials may blow about,
potentially causing personal injury or
equipment damage.
Inappropriate or poorly maintained fencing
during construction intended to deter human
and animal intrusions into the AOA. Fencing
and other markings that are inadequate to
separate construction areas from open AOA
create aviation hazards.

Item
Action Required (Describe)
No Action
Required
(Check)
Improper or inadequate marking or lighting
of runways (especially thresholds that have
been displaced or runways that have been
closed) and taxiways that could cause pilot
confusion and provide a potential for a
runway incursion. Inadequate or improper
methods of marking, barricading, and lighting
of temporarily closed portions of AOA create
aviation hazards.
Wildlife attractants — such as trash (food
scraps not collected from construction
personnel activity), grass seeds, tall grass, or
standing water — on or near airports.
Misleading or malfunctioning obstruction
lights. Unlighted or unmarked obstructions in
the approach to any open runway pose
aviation hazards.
Failure to issue, update, or cancel NOTAMs
about airport or runway closures or other
construction related airport conditions.
Failure to mark and identify utilities or power
cables. Damage to utilities and power cables
during construction activity can result in the
loss of runway / taxiway lighting; loss of
navigation, visual, or approach aids;
disruption of weather reporting services;
and/or loss of communications.
Lack of radio communications with
construction vehicles in airport movement
areas.
Objects, regardless of whether they are
marked or flagged, or activities anywhere on
or near an airport that could be distracting,
confusing, or alarming to pilots during
aircraft operations.
Water, snow, dirt, debris, or other
contaminants that temporarily obscure or
derogate the visibility of runway/taxiway
marking, lighting, and pavement edges. Any
condition or factor that obscures or
diminishes the visibility of areas under
construction.
Spillage from vehicles (gasoline, diesel fuel,
oil) on active pavement areas, such as
runways, taxiways, aprons, and airport
roadways.

Action Required (Describe)
No Action
Required
(Check)
Failure to maintain drainage system integrity
during construction (for example, no
temporary drainage provided when working
on a drainage system).
Failure to provide for proper electrical lockout
and tagout procedures. At larger airports with
multiple maintenance shifts/workers,
construction contractors should make
provisions for coordinating work on circuits.
Failure to control dust. Consider limiting the
amount of area from which the contractor is
allowed to strip turf.
Exposed wiring that creates an electrocution
or fire ignition hazard. Identify and secure
wiring and place it in conduit or bury it.
Site burning, which can cause possible
obscuration.
