2.1.3 Electric Conduit: Native soil free from broken concrete, timber, roots or 
other debris; processed granular material (aggregate base or select material); 
ASB or LMB. Backfill within 6 inches (152mm) of conduit shall have no solid 
material with sharp edges greater than 1-½ inches (38mm) in maximum 
dimension and contain more than 50% passing the 3/8-inch (9.53mm) sieve. The 
balance of the trench backfill shall have no solid material with sharp edges 
greater than 4 inches (102mm) in maximum dimension and contain more than 
50% passing the 3/8-inch (9.53mm) sieve. 
 
2.1.4 Direct Burial Cable: Backfill within 6 inches (152mm) of the cable shall be 
processed sand or native material free of angular (sharp) rocks, broken concrete, 
timber, roots or other debris, which contains no particles larger than 3/8-inch 
(9.5mm) in greatest dimension. The balance of the trench backfill shall be native 
soil free from broken concrete, timber, roots or other debris, or processed 
granular material (aggregate base or select material), with no solid material with 
sharp edges greater than 4 inches (102mm) in maximum dimension and contain 
more than 50% passing the 3/8-inch (9.53mm) sieve. 
 
2.1.5 Gas Pipe: Processed granular or sand material free of broken concrete, 
timber, roots or other debris, which contains no particles larger than 1/8-inch

EXECUTION 
 
3.1 
General 
 
3.1.1 Use excavation shoring, bracing, sheeting, barricading and plating 
necessary to perform work and protect excavation and personnel as required for

SRP 02224                                                                                                    Page 4 of 7 
safety and conformance to governing law, including OSHA Construction 
Standards, Subpart P, and Salt River Project Excavation Safety Resource 
Manual. Cost of protection systems shall be included in Contractor bid price. 
 
3.1.2  Sawcutting of the concrete and asphalt shall be required for trenches in 
paved streets, alleys, driveways, sidewalks, etc. Sawcuts shall be to the full 
depth of the material, leaving neat, vertical, true lines in such a manner that 
adjoining surfaces will not be damaged. 
 
3.1.3 Maximum continuous length of open trench shall not exceed the 
requirements of the governing municipality. A trench shall be considered open 
until backfilled to the top of subgrade on unsurfaced areas and the top of base 
course on pavements. 
 
3.1.4  Trenches crossing streets shall be backfilled as soon as possible after 
placement of conduit, pipe or structures. Substantial steel plates with adequate 
trench bracing shall be used to bridge across trenches at street crossings where 
backfill and patching have not been completed during work hours. 
 
3.1.5  Provide safe and convenient passage for pedestrians. Maintain access to 
hospitals, fire stations, fire hydrants at all times. The Engineer retains the option 
to designate a passage to be provided at any point he deems necessary. 
 
3.2 
Excavation 
 
3.2.1 Excavations for utility trenches shall conform to the dimensions, elevations, 
grades and tolerances indicated, with allowances for minimum required bedding 
width, accommodation of compaction equipment and erection of forms. Lines and 
grades shall be established prior to excavating. 
 
3.2.2 If excavation is carried beyond the dimensions, elevations or grades 
indicated on the Drawings without the Engineer's approval (except where 
necessary to meet bedding, compaction or forming requirements), the 
overexcavated area shall be cleaned of all loose material and backfilled at the 
Contractor's expense. Backfill material and compaction requirements shall be 
specified by the Engineer.   
 
3.2.3 The trench bottom shall be level for its full width to provide uniform bearing 
and support. Excessive tooth marks shall be removed or compacted level. In 
rock, bottom of trench may be over-excavated a maximum of 6 inches (152mm) 
and filled with granular material to provide a smooth surface. Granular material 
shall be compacted to meet requirements shown on the Drawings. 
 
3.2.4 Use of explosives is generally not permitted. If explosives are to be used, 
a controlled blasting plan that meets the requirements of Appendix A must be 
submitted and approved by the Engineer prior to such use. Contractor shall

SRP 02224                                                                                                    Page 5 of 7 
comply with applicable ordinances and regulations, and shall state in his proposal 
if bid is based on use of explosives. Contractor shall be responsible for any 
damages occurring due to use of controlled blasting. 
3.2.5  Where non-blast related construction activities have the capability to cause 
vibrations of sufficient intensity to damage structures, Contractor shall meet 
vibration requirements of Appendix A. 
3.2.6 Where soil incapable of supporting the conduit, pipe or structure is 
encountered, Contractor will notify the Engineer and a determination will be 
made as to the depth of over-excavation and the type of granular fill required. 
 
3.2.7  Berm or otherwise protect trenches from surface drainage or runoff. 
 
3.3 
Bedding 
 
3.3.1  Clean trench of loose material, rocks, weld rod, or other debris prior to 
placement of bedding. 
 
3.3.2 Material upon which conduit, pipe or structure is to be placed shall be 
accurately finished and compacted to the grade or dimensions shown on the 
plans. Bedding or trench bottom shall be brought to final grade so conduit, pipe 
or structure will be continuously in contact with material on which it is placed. 
Bedding material shall be within 2% of optimum moisture and compacted to the 
required density by the specified method in 6 inch (0.15m) or smaller 
uncompacted lifts. 
 
3.3.3 Bedding material shall be as noted on the plans or in the specifications. 
 
3.4 
Backfilling 
 
3.4.1 Backfill material shall be uniformly within 2% of optimum moisture content 
prior to placement in the trench. Place backfill in level lifts simultaneously on both 
sides of the conduit, pipe or structure unless otherwise specified. 
 
3.4.2 Backfill trenches in such a manner as to prevent disturbance to the pipe or 
conduit. 
 
3.4.3 Backfill from bedding to a point approximately 6 inches (152mm) above the 
top of pipe or conduit shall be placed as follows (backfill material shall be as 
specified on the plans): 
 
(a) Native material: Place in maximum uncompacted lifts of 8 inches (0.2m) and 
compact to the required density by the specified method. Native material shall 
contain no aggregate or pieces greater than 1/3 the width of the trench on 
each side of the conduit, pipe or structure and in no case exceed 3 inches 
(76mm) in maximum dimension.

SRP 02224                                                                                                    Page 6 of 7 
 
(b) Processed granular and sand material: Place in maximum uncompacted lifts 
of 12 inches (0.3m) and compact to the required density by the specified 
method. 
 
(c) ASB: Discharge directlly into the trench from the mixer, with even distribution 
on each side of conduit or pipe. ASB shall flow freely and uniformly around 
and under conduit or pipe without leaving voids. 
 
3.4.4 Backfill shall be placed from 6 inches (152mm) above top of pipe or conduit 
to finished surface as follows: 
 
(a) Unless otherwise specified, native material containing aggregate or pieces up 
to 6 inches (0.15m) in maximum dimension may be used. Under pavements, 
sidewalks, curbs, etc., pieces larger than 3 inches (0.1m) will not be allowed 
for use in the final 12 inches (305mm) below pavement base. 
 
(b) The Engineer may allow Contractor to exceed specified lift depth limits where 
Contractor demonstrates the ability to meet compaction requirements with 
proposed equipment and methods. Lift thicknesses shall not exceed that 
which can be effectively compacted by type of equipment and method used. 
 
3.4.5 When backfilling with ASB or LMB, place in lift depths that will not allow the 
conduit, pipe or structure to move (float). 
 
3.4.6 Backfill around existing utilities exposed during trench excavation in 
accordance with bedding methods, Section 3.3. 
 
3.5 
Quality Control 
 
3.5.1  Inspection and compaction tests are required on trench beddings and 
backfills unless LMB slurries are used. 
3.5.2  Density and moisture content will be verified during construction by the 
Engineer at no cost to Contractor. Test will be made at the discretion of the 
Engineer. Retesting for non-compliance shall be at Contractor's expense. 
3.5.3  Do not cover lifts before compaction tests are performed. If lifts are 
covered prior to testing, excavate test pits for making density tests on lower 
portions of backfill at instruction of the Engineer. Refill and compact test pits in 
accordance with the specifications. Excavating, refilling and compacting test pits 
shall be at Contractor's expense.
