SCOPE OF SERVICES - PROJECT SPECIFIC
Project Overview
Project Location
The project will reconstruct Gilbert Road between Thomas Road and SR 87 (Beeline Highway) in
Maricopa County to provide an all-weather roadway over the Salt River and connection to SR 87.
Project Background
This change order accounts for the following scope items:
I. Extending the main Gilbert Road Bridge from 1,445 feet to 3,685 feet.
2. Adding a new 450 foot bridge "Northern Reliever Bridge".
3. Preparing new 60% Plans, Specifications, and Cost Estimate.
4. Additional effort to complete 95%, 100%, and Sealed submittals with new project definition.
5. Providing Post Design services.
Project Purpose
The purpose of the change order is as follows:
1. After completing additional hydraulic analysis, utilizing 2-D modeling (Change Order #3),
11DR developed numerous alternatives which focused on key objectives of not worsening
flooding of properties outside of the ROW, including along Roma Ave during a 100-year storm
event and keeping all proposed improvement within ROW. After considering all of the
information, MCDOT and project stakeholders selected an alternative (Alternative 3A) which
extended the main Gilbert Road Bridge over the Salt River from 1,445 feet to 3,685 feet. This
extension results in the northern abutment moving further to the north. The southern abutment
will remain in the same location as previously identified and the horizontal alignment will
remain the same.
1 As part of Alternative 3A, it was determined that a new bridge structure is needed
approximately 2,000 feet north of the main Gilbert Road Bridge. This new bridge "Northern
Reliever Bridge" allows for the conveyance of various flood water that is "pushed" up towards
Roma Avenue during a 100-year storm event to drain underneath Gilbert Road rather than
perpetuate flooding of the areas along Roma Avenue. Based on the analysis, a proposed bridge
(or equivalent hydraulic structure) with an opening length of 450 feet is needed to provide
adequate relief drainage.
3. With the changes to the main bridge, the addition of a completely new bridge structure, and the
associated changes with the roadway profile to accommodate these changes, a new 60% design
plan submittal is required. The critical path for this project is getting the Conditional Letter of
Map Revision (CLOMR) submitted and approved. The scope changes associated with
Alternative 3A directly impact the evaluation current design package and the CLOMR thus
requiring a completely new 60% submittal.
4. With the additional length of the main Gilbert Road Bridge and the new Northern Reliever
Bridge, additional efforts will be required in developing the 95%, 100%, and Sealed project
submittals as a function of the increase infrastructure and projects over design complexity.

200 Project Management, Meetings, and Coordination
200.1 Project Management
Due to the extension of the project schedule and with providing a revised 60% design plan submittal,
time has been included for the HDR project manager to manage the project, develop and regularly
review and update the design schedule, regularly review the design budget, monitor and control the
project progress, schedule and budget, and to develop invoices.
200.2 Progress/Coordination Meetings
Time has been included to prepare for, write agendas, attend meetings, travel to and from meetings and
document and distribute meeting notes for the project coordination meetings listed included in this task.
Time has been included to participate in additional agency and stakeholder coordination meeting to
share the findings and recommendations of this project. Additional time has been added to support
public outreach and public meetings to obtain community approval for the recommended alternatives.
In conjunction with mcDoT, HDR will hold approximately six (6) additional monthly progress
meetings where all stakeholders will be invited and project progress, issues and direction will be
discussed and documented. Time is also included for a new 60% comment resolution meeting.
300 Revised 60% Design Plans, Specifications, and Cost Estimate
Due to the significant level of change to the scope of the project, primarily more than doubling of the
main Gilbert Road Bridge and the addition of the new Northern Reliever Bridge, located slightly south
of Roma Avenue, a new 60% design plan submittal is required. While certain elements of the previous
60% submittal (submitted July 19, 2017) can be resubmitted without modification, the majority of plans
require re-work. A description of the modifications for each discipline are detail below.
300.1 Civil
This task consists of civil design efforts associated with updating the roadway layout, performing
additional design associated with the change in the bridge layout, performing additional design
associated with the addition of the northern reliever bridge, revising the drawings that were included in
the original 60% submittal, and resubmitting the 60% submittal. Unless noted herein, the scope
provisions for the civil final design and development of plans included in the original contract still
apply. This includes design specifications, design guidelines, construction specifications, and submittal
requirements.
The roadway design will follow the current MCDOT Roadway Design Manual, standards and
guidelines and utilize current MAG and MCDOT standard details as much as practical. Roadway cross
sections will be prepared at appropriate locations to provide accurate earthwork calculations at regular
intervals along the alignment. The design will rely on the topographic surveys, mapping and digital
terrain models (DTM) provided by MCDOT. The roadway will be designed using InRoads software.
Earthwork will be calculated using the average end area method.
The following is assumed for the new civil layout: (1) the roadway profile grade will be changed,
resulting in modifications to geometry; (2) roadway design coordination with other technical disciplines
is required to account for the extend bridge and the new reliever bridge; (3) the location of the south
abutment of the main Gilbert Road Bridge will remain unchanged; (4) the east maintenance road will be
combined with the drainage ditch/channel to reduce impacts to existing right-of-way; (5) maintenance
of traffic and construction sequence plans will need to be revised to account for the extended bridge and
the new reliever bridge.

300.2.1 Hydrologic and Hydraulic Modeling
This task is comprised of the efforts related to the Hydrologic and Hydraulic modeling
associated with the new project configuration. The two-dimensional modeling previously
performed allowed for the recommendation of lengthening the main Gilbert Road bridge and
adding a new northern reliever bridge. With this direction, new one-dimensional modeling is
now required to be performed for submission to FEMA and for developing of the revised
Drainage Report. The majority of work associated with the original 1D modeling was
performed and completed as part of the original 60% submittal. With the new project
configuration, a large portion of the hydrologic and hydraulic modeling will recreated. The
following describes the detail of this work.
Drainage design shall be in accordance with the Drainage Policies and Standards for Maricopa
County, Arizona. Hydrology, hydraulics, and erosion control designs shall be consistent with
the current Drainage Design Manual issued by the Flood Control District of Maricopa County.
Both on and off site drainage design shall be in accordance with the Drainage Policies and
Standards for Maricopa County, Arizona. Hydrology, hydraulics, and erosion control designs
shall be consistent with the current Drainage Design Manual issued by the Flood Control
District of Maricopa County. The bridge and other pertinent apertures conveying the regulatory
floodwaters will be designed to be compliant with 44 CFR 60.3 and local floodplain ordinances
with regards to acceptable impacts to the floodway and floodplain water surface elevations.
Onsite
On site study limits are defined as the area along the Gilbert Road alignment (existing and
proposed) between Thomas Road and SR 87 (Beeline Highway) extending to the edge of right
of way limits.
The on site drainage and storm water pollution prevention plan (SWPPP) design will follow the
current MCDOT standards and guidelines and utilize current MAG and MCDOT standard
details. Where MCDOT and MAG standards do not address specific criteria or issues the
CONSULTANT (.12) will follow additional pertinent standards. Additional pertinent standards
include ADOT, FCDMC, FHWA, and SRPMIC.
Project No.: TT0339 Contract No.: 2015-039

Scope of Services
Project Specific
The Rational Equation shall be utilized for hydrologic analyses. The rainfall intensity shall be
based on the 10-year 10-minute storm utilizing current NOAA Atlas 14 precipitation intensities
and depths. Cross drainage facilities shall be designed for the 50-year storm event. The design
will rely on the topographic surveys, mapping and digital terrain models (DTM) provided by
MCDOT.
See CONSULTANT (J2) Scope for further details on criteria, analysis, and project deliverables.
Offsite
Off site study limits will be defined as extending from approximately 5 miles downstream of the
existing Gilbert Road alignment (Alma School Bridge) to 5 miles upstream of the alignment
near Granite Reef Dam..
Additional offsite analysis will include stormwater discharge determined to be an impact to the
Gilbert Road alignment (existing and proposed) as defined within the project limits of this scope
of work. Roadway Cross drainage facilities shall be designed for the 50- year storm event.
The off site drainage design will follow the current MCDOT standards and guidelines and
utilize current MAG and MCDOT standard details. Where MCDOT and MAG standards do not
address specific criteria or issues the CONSULTANT (J2) will follow additional pertinent
standards as directed by UDR. Additional pertinent standards include ADOT, FCDMC, FHWA,
and SRPMIC.
111)R will verify the assumptions made by the sub consultant in regards to design discharge
values to be utilized for the Salt River crossing. The values shall be based on the Post-
Roosevelt discharges developed by the U.S. Army Corps of Engineers. These values have been
utilized for design of the Salt River improvements through the metropolitan Phoenix area.
See CONSULTANT (12) Scope for further details on criteria, analysis, and project deliverables.
Drainage plans are to be accompanied by a sealed drainage report when submitted to MCDOT
for review. The drainage report will be comprehensive and include applicable: hydrology and
hydraulic calculations, documented computer modeling, maps, and other supporting data and
analyses.
Quality Assurance
HDR shall provide independent Quality Assurance for the all hydrologic and hydraulic analysis,
modeling approaches, computations, and associated work products prepared by the teaming
partner. Hydrology will be reviewed with respect to the Drainage Design Manual for Maricopa
County, as prepared by the Flood Control District of Maricopa County, release date 2013.
Hydraulics will be reviewed with respect to the Drainage Design Manual for Maricopa County,
as prepared by the Flood Control District of Maricopa County, release date 2013 along with

Quality Assurance
HDR shall provide independent Quality Assurance for the scour computations and associated
revetment and scour protection design plans prepared by subconsultant. Detailed review of
scour assumptions, engineering approach, countermeasure design, conveyance features,
identification of potential impacts to right-of-way, and effects on the Salt River hydraulics will
be conducted. Scour and erosion control will be reviewed with respect to Chapter 11 of the —
Hydraulic Drainage Design Manual for Maricopa County, as prepared by the Flood Control
District of Maricopa County, release date 2013.
300.2.3 Drainage Meetings and Project Coordination
HDR shall conduct regular internal drainage coordination meetings to support project status and
action item reviews. HDR shall conduct weekly coordination calls and meetings with both J2
and JE Fuller, facilitate the exchange of information and approach between the drainage team,
identifying any challenges, opportunities, or recommendations with respect to the drainage
evaluation and associated design components. All drainage meetings and team conference calls
shall be documented as formal meetings using HDR standard templates. Standalone discussions
with the subconsultant teams, members of the team, or other will be necessary during this
project. A brief record of the discussion, the parties involved, and key notes will be documented
and added to project tracking with HDR standard templates.
HDR Drainage Lead shall participate in public meeting and stakeholder outreach in support of
communications with MCDOT for proactive messaging of project findings and
recommendations of potential FEMA outcomes.
300.2.4 Drainage Construction Plans (Revised 60%)
HDR shall facilitate the coordination and development of the construction plans, details, and
specification for the design package of the Revised 60% review of the project. The HDR
drainage lead shall be involved in ongoing discussions and review of plan components to
support the early identification of potential conflicts or challenges.
300.2.5 Conditional Letter of Map Revision
Based on the new project configuration, the Conditional Letter of Map Revision (CLOMR) will
require significantly more effort and coordination with Flood Control District of Maricopa
County (FCDMC), FEMA, and MCDOT than was originally scoped for the project.
In order to assist with the FEMA review and approval process, an in-person meeting with the
assigned FEMA reviewer is proposed. The purpose of this meeting is to provide a detailed
explanation of the project, the special conditions associated with the CLOMR, and to answer
questions early to prevent a project review stall out. The location of this meeting will not be
known until FEMA has assigned the case to a specific review. It is anticipated that the meeting

will require travel out of state. This scope provides for travel, including airfare, with per diem.
For two I-LDR staff and one representative from subconsultant J2. Additional representation
from MCDOT and FCDMC will be required as well. This scope and budget does not include
recovery costs for mcDorr and FCDMC, it is understood those services will be funded
separately by others.
300.3 Structural
300.3.1 Bridge Final Design and Plans
The layout of the Main River Bridge will be revised from nine spans to an assumed layout of
twenty-three spans. This task consists of bridge design efforts associated with updating the
bridge layout, performing additional design associated with the change in the bridge layout,
revising the drawings that were included in the original 60% submittal, generating new
drawings required for the new bridge layout, and resubmitting the 60% submittal. Unless noted
herein, the scope provisions for the bridge final design and development of plans included in the
original contract still apply. This includes design specifications, design guidelines, construction
specifications, and submittal requirements. Contrary to the scope of work in the original
contract, but as shown in the original 60% submittal, the bridge will consist of a precast
concrete Bulb Tee girder superstructure supported on 2-column piers founded on drilled shafts.
Due to the possibility that the hydraulic design conditions (i.e. flow, velocity, scour, etc.) for the
north half of the proposed bridge may not be as severe, and that designing to meet these
conditions will reduce cost, it is assumed that a new/separate pier design is included.
The following is assumed for the new twenty-three span bridge layout:
(1) An updated Bridge Selection Report will not be required;
(2) The bridge horizontal alignment and skew of the piers and abutments will match
the original 60% submittal;
(3) The span lengths will match the original 60% submittal;
(4) The profile grade will be changed, resulting in modifications to geometry;
(5) The size and spacing of columns at all piers will not change and will match the
original 60% submittal;
(6) The size and depth of the pier drilled shafts for the spans included with the
original 60% submittal will not change;
(7) A new drilled shaft size and depth will be required for the piers within the
extended limits of the bridge;
(8) The size and spacing of the drilled shafts at Abutment 1(south end) will remain
unchanged;
(9) The size and spacing of the drilled shafts at the new Abutment 2 (north end) will
match Abutment 1;
(10) The wing walls at both abutments will be similar in length as shown on the
original 60% plans, thus wing wall redesign will not be required. However,
during the original 60% design, it was determined that retaining walls will be
necessary beyond each abutment wing wall (not feasible to extend wing walls
past the slope catch point). The layout/design of these retaining walls (1 sheet) is
included with this change order since it was not included in the original scope of
work and fee proposal;
Project No.: TT0339 Contract No.: 2015-039

(11) The new twenty-three span layout will consist of 7 three-span frames and 1 two-
span frame, thus requiring consideration of design and details for a two-span
frame (the original 60% submittal only consisted of three-span frames);
(12) A deck drainage system will not be required.
The following list of bridge drawings identifies the existing drawings included as part of the
original scope of work (for the bridge length included in the original 60% submittal) and new
drawings required for the new bridge layout. For the existing drawings, the list notes which

300.4 Geotechnical
With the length of the main bridge expanding from 1,445 feet to 3,685 feet, a significant amount of
geotechnical investigation will be required to account for the increased number of bridge foundations.
The following descriptions accounts for geotechnical investigation of both the main bridge, the new
northern reliever bridge, and the roadway embankment segment between the two bridges.
300.4.1 Exploration & Access Plan Preparation
Terracon, accompanied by MR, will perform a site visit to evaluate the prospective boring
locations, site and access constraints, traffic control requirements, and other logistics of the field
investigation which require consideration. HDR will prepare a draft Geotechnical Investigation
and Boring Plan which will depict the boring locations and depths, proposed access routes, and
estimated areas of ground surface disturbance, and include a description of the drilling
equipment and methods, and will submit the draft Plan to MCDOT (including to MCDOT
Materials Group), and the HDR Design Team. The Plan will be a modification of the boring
plan developed for the investigation of the original (60 Percent Design Phase) nine-span main
river bridge layout. HDR will revise the draft Plan in response to review comments from
MCDOT Materials Group and the team, and submit a final Plan to MCDOT and the design
team.
300.4.2 Environmental & Encroachment/Access Permits Coordination
Environmental Review & Clearances: The Geotechnical Investigation and Boring Plan prepared
by HDR will be submitted to MCDOT Engineering Division, Environmental Program Branch
planners for their use in obtaining environmental permits for geotechnical field work, including
for the MCDOT environmental clearance and applying for the SRPMIC Environmental Review
and clearance. Communications and coordination with MCDOT Environmental Program
Branch will be required during the permitting process for the geotechnical field investigation.
Further, HDR will coordinate with MCDOT and the SRPMIC to determine if SRPMIC
representative(s) need to be present during the geotechnical field work. It is assumed that
advance notification of SPRMIC by HDR will be required prior to initiation of the field work.
An estimate of the area of disturbance due to the field investigation will be prepared by
Terracon and submitted as part of the environmental clearance package. The area of disturbance
estimate will include the boring locations themselves, access route to each boring location
(travel off of existing roadways), and each boring work zone including drill spoils.
All project field personnel will have completed the required cultural sensitivity training course
administered by SRPMIC.
Encroachment Permits: Terracon will apply for and secure an encroachment permit from
MCDOT for work within the Gilbert Road right-of-way, and an access permit from SRPMIC
for work within the Community's right-of-way, including preparing and submitting a traffic
control plan for proposed borings adjacent to the existing roadway. Traffic lane closures are not
anticipated to be needed for this field investigation. Borings along the existing Gilbert Road will
be located on or adjacent to the existing roadway shoulder and include shoulder closures and
"shoulder work ahead" signage. No borings are anticipated to be located within existing
MCDOT or SRPMIC paved roadways.
ADWR Permits & Boring Backfill/Abandonment: For the 60 Percent Design field
investigation, it was determined by Terracon that ADWR permits for borings which encounter
groundwater were not needed, as ADWR indicated they have no permit jurisdiction on SRPMIC
lands. Regardless, the top 20 feet of all bridge borings will be backfilled with cement-bentonite
