This section covers furnishing all labor, supervision, materials, and equipment and performing all operations necessary to furnish and install the piping and fittings. All pipe and fittings, and accessories furnished by the Contractor shall be new material free from rust or corrosion. All piping and fittings shall be cleaned on the inside when installed and the Contractor shall take all necessary precautions to ensure that the lines are kept free of any foreign matter and dirt until the work is completed. All pipes shall be carefully placed and supported at the proper lines and grades as shown on the drawings. Piping runs shown on the drawings shall be followed as closely as possible except for minor adjustments to avoid other piping or structural features. If major relocations are required, they shall be approved by the Construction Manager/Resident Engineer. The bedding shall be defined as that material supporting, surrounding, and extending to one foot above the top of the pipe. If soft, spongy, unstable, or similar other material is encountered upon which the bedding material or pipe is to be placed, this unsuitable material shall be removed to a depth ordered by the City Engineer and replaced with bedding material suitably densified. Bedding material shall first be placed so that the pipe is supported for the full length of the barrel with full bearing on the bottom segment of the pipe. Hunching of the pipe shall not be allowed. Pipe will be carefully inspected in the field before and after laying. If any cause for rejection is discovered in a pipe after it has been laid, it shall be subject to rejection. Any corrective work shall be approved by the Construction Manager/Resident Engineer.

Pipe shall be laid true to line and grade with uniform bearing under the full length of the barrel of the pipe. Suitable excavation shall be made to receive the bell or collar which shall not bear upon the subgrade or bedding. Any pipe which is not in true alignment or shows any undue settlement after laying shall be taken up and relaid at the Contractor's expense.

18.a
Packet Pg. 568 Attachment: PHASE II VOLUME 1 (5475 : Approval of Plans and Specs - Imperial Avenue Extension Phase II) 94 Pipe shall be laid upgrade with the socket ends of the pipe upgrade unless otherwise authorized by the Construction Manager/Resident Engineer. Pipe sections shall be laid and joined in such a manner that the offset of the inside of the pipe at any joint will be held to a minimum at the invert. The maximum horizontal offset at the invert of the pipe shall be 1% of the inside diameter of the pipe or 0.02 feet, whichever is smaller. The vertical grade shall be +/- 0.02 feet of the design invert. In joining socket pipe, the spigot of each pipe shall be so seated in the socket of the adjacent pipe as to give a uniform annular space all around the pipe in the socket. Unavoidable offsets shall be distributed around the circumference of the pipe in such a manner that the minimum offset occurs at the invert. At the close of work each day, or whenever the work ceases for any reason, the end of the pipe shall be securely closed.

The width of the trench depends on the pipe diameter, backfill material, and the method of compaction.

Trenches that are too narrow will not allow for proper pipe installation, whereas trenches that are overly wide are unnecessarily costly. As a practical matter, standard bucket sizes may also factor into the decision.

Minimum trench widths shall conform to the below table.

MINIMUM TRENCH WIDTHS
Pipe Diameter, in. (mm) Minimum Trench, in.
(m)
4-8 (100-200) *
10 (250) 24 (0.6)
12 (300) 28 (0.7)
15 (375) 35 (0.9)
18 (450) 43 (1.1)
24 (600) 56 (1.4)
30 (750) 60 (1.5)
36 (900) 65 (1.7)
42 (1050) 84 (2.1)
48 (1200) 91 (2.3)
54 (1350) 97 (2.5)
60 (1500) 103 (2.6)
*Usually dependent on the smallest bucket size
available
These minimum trench widths are necessary for suitable in situ soils. These widths generally allow for backfill material to flow on either side of the pipe and permit many types of compaction equipment. If the width is not sufficiently wide for the materials and methods proposed, a wider trench allowing for proper installation should be constructed.

B. SHORING AND SHEETING
The Contractor shall do such trench bracing, sheathing, or shoring necessary to perform and protect the excavation as required for safety and conformance to governing laws. The bracing, sheathing, or shoring shall not be removed in one operation but shall be done in successive stages to prevent overloading of the pipe during backfilling operations. All shoring and sheeting deemed necessary to protect the excavation and to safeguard employees, shall be installed.

C. OPEN TRENCH
Except where otherwise noted in the special provisions, or approved in writing by the Construction Manager/Resident Engineer, the maximum length of open trench, where the construction is in any stage of completion (excavation, pipe laying or backfilling), shall not exceed 1,320 feet in the aggregate area of

18.a
Packet Pg. 569 Attachment: PHASE II VOLUME 1 (5475 : Approval of Plans and Specs - Imperial Avenue Extension Phase II) 95 a street at any one location.

Any excavated area shall be considered open trench until the trench backfill has been placed to subbase level, the level of the bottom of the class 2 base. With the approval of the Construction Manager/Resident Engineer, pipe laying may be carried on at more than one separate location, the restrictions on open trench applying to each location. Trenches across streets shall be completely backfilled as soon as possible after pipe laying.

Substantial steel plates with adequate trench bracing shall be used to bridge across trenches at street crossings where trench backfill and temporary patches have not been completed during regular work hours. Safe and convenient passage for pedestrians shall be provided. The Construction Manager/Resident Engineer may designate a passage to be provided at any point deemed necessary.

Access to hospitals, fire stations, schools, post offices, public facilities and fire hydrants shall be maintained at all times.

D. PROTECTION OF EXISTING UTILITIES
1) UTILITIES: Unless otherwise illustrated on the plans or stated in the specifications, all utilities, both underground and overhead, shall be maintained in continuous service throughout the entire contract period. the Contractor shall be responsible and liable for any damages to or interruption of service caused by the construction.

If the Contractor desires to simplify his operation by temporarily or permanently relocating or shutting down any utility or appurtenance, the Contractor shall make the necessary arrangements and agreements with the Utility Purveyor and shall be completely responsible for all costs concerned with the relocation or shutdown and reconstruction. All property shall be reconstructed in its original or new location as soon as possible and to a condition at least as good as its previous condition. This period of relocation or shutdown and reconstruction shall be subject to inspection and approval by both the Construction Manager/Resident Engineer and the Utility Purveyor.

The Contractor shall be entirely responsible for safeguarding and maintaining all conflicting utilities that are illustrated on the plans. This includes overhead wires and cables and their supporting poles whether they are inside or outside of the open trench. If, in the course of work, a conflicting utility line that was not illustrated on the plans is discovered, the Contractor shall either negotiate with the Utility Purveyor for relocation, relocate the utility or change the alignment and grade of the trench.
2) BUILDING, FOUNDATIONS AND STRUCTURES: where trenches are located adjacent to buildings, foundations, and structures, the Contractor shall take all necessary precautions against damage to them. The Contractor shall be liable for any damage caused by the construction.

Except where authorized in the special provisions or in writing by the City Engineer, water settling of backfill material in trenches adjacent to structures will not be permitted. 3) ELECTRONIC, TELEPHONIC, TELEGRAPHIC, ELECTRICAL, OIL, AND GAS LINES: These underground facilities shall be adequately supported by the Contractor. Support for plastic pipe shall be continuous along the bottom of the pipe. Support for metal pipe and electrical conduit may be continuous or nylon webbing may be used for suspension at no greater than ten-foot (10’) intervals.

The Contractor shall avoid damaging the plastic pipe, pipe ways, or conduits during trench backfilling and during foundation and bedding placement.

E. COMPACTION METHODS
Backfill material shall be compacted with hand and/or mechanical work methods using equipment such as

18.a
Packet Pg. 570 Attachment: PHASE II VOLUME 1 (5475 : Approval of Plans and Specs - Imperial Avenue Extension Phase II) 96 roller, pneumatic tamps, hydro-hammers, or other approved devices which secure uniform and required density without injury to the pipe or related structures.

Water consolidation by jetting or flooding is not acceptable as a soil consolidation method unless authorized in the technical specification or approved by the Construction Manager/Resident Engineer.

F. RIGHTS-OF-WAY BELONGING TO OTHERS
Where the permit of a governing agency sets forth requirements for compaction more stringent than those stated herein, the Contractor shall adhere to the more stringent requirements.

G. LEAK TESTING FOR STORMWATER MANHOLES/VAULTS
The Contractor shall leak test 100% of the stormwater manholes/vaults installed for this project.

The Contractor shall test all manholes/vaults using the following test procedure:

The Contractor shall fill the manholes/vaults with water and allow the interior surfaces of the manholes/vaults to soak for four (4) hours. The leak test shall then commence. Water tightness testing shall consist of filling the manholes/vaults with water to an established level. The Contractor shall ensure that the drop in water level does not exceed 0.001 of the total manhole/vault volume in one (1) hour.

H. ADDITIONAL TESTING

The Contractor shall perform deflection testing for 100% of stormwater lines to ensure that the installation meets or exceeds the manufacturer’s recommendations.

The Contractor shall perform deflection testing on the system as directed by the Construction Manager/Resident Engineer. The deflection testing shall be accomplished by mandreling the pipeline.

Any part of the installation, which shows deflection in excess of 5% of the average inside diameter per ASTM D3034 for PVC pipe, shall be corrected.

After acceptance but prior to the termination of the warranty period, the City of El Centro may test the long-term deflection of the stormwater pipeline. If the City of El Centro determines that the deflection has exceeded 7 ½% of the average inside diameter, that portion of the installation shall be corrected by the Contractor at no cost to the City of El Centro.

The Contractor shall perform a watertight field performance test on 100 % of the stormwater pipeline installed. The watertight field performance test shall be accomplished after the deflection testing of the stormwater pipeline is accomplished.

Stormwater lines shall be subject to acceptance testing after backfilling has been completed but prior to the placement of the finished surface material, (Class 2 base, A.C. Pavement, and P.C.C. Concrete).

The cost of repairs or corrections necessary to conform to the testing requirements will be borne by the Contractor at no cost to the City of El Centro.

A watertight field performance test shall be accomplished according to ASTM F1417 or ASTM C969 as determined by the Construction Manager/Resident Engineer. The costs to complete the watertight field performance test shall be borne by the Contractor
I. CONCRETE
The portland concrete cement for the manhole bases, manhole grade rings, and all other concrete infrastructure shall be Type “V” and contain a minimum of 7 sacks of cement per cubic yard and attain

18.a
Packet Pg. 571 Attachment: PHASE II VOLUME 1 (5475 : Approval of Plans and Specs - Imperial Avenue Extension Phase II) 97 5,000 psi compressive strength after 28 days of curing. The concrete slump shall not exceed 4.5 inches.

The City Engineer shall be provided with a copy of the concrete vendor’s delivery slip. One (1) slip shall be provided for each concrete delivery truck. One (1) set of concrete cylinders shall be obtained for every six (6) manhole bases constructed at a project site. It shall not be required to obtain and test concrete cylinders on projects with less than six (6) manhole bases. A set of cylinders shall be defined as three (3) cylinders. One (1) cylinder shall be tested 7 days after concrete placement. The second cylinder shall be tested 28 days after concrete placement. The third cylinder shall be held in reserve and tested at the direction of the City Engineer.

J. DUCTILE IRON FITTINGS
Fittings for the stormwater pipeline shall be composed of ductile iron. The ductile iron mechanical joint fittings shall conform to AWWA C153. The ductile iron-flanged fittings shall conform to AWWA C110.

The fittings shall be cement mortar lined in accordance with ANSI/AWWA C104/A21.4, standard for cement mortar lining for ductile iron, and gray iron pipe fittings for water, latest revision. The pressure rating for 3 inch – 24-inch diameter sizes shall be 350 psi. The pressure rating for 30 inch – 48-inch diameter sizes shall be 250 psi.

K. EXCAVATIONS FOR STORMWATER PIPELINE
Shallow, temporary excavations, less than four feet deep, in native clay soils should stand nearly vertical for short duration. All temporary excavations over four feet in depth will require shoring or slope inclinations in conformance to CAL OSHA Standards for Type C soils. These temporary deep excavations will require slope inclinations no steeper than 1:1 vertical height to horizontal length unless trench shoring is used.

Stable excavation slopes assumes minimal equipment vibration and adequate setback of excavated material and construction equipment from the top of the excavation. It is recommended that the minimum setback distance be equal to the depth of excavation and at least 5 feet from the crown of the slope. If excavated materials are stockpiled adjacent to the excavation, the weight of the material should be considered as a surcharge load for slope stability.

All excavations shall be constructed in conformance to the CALOSHA requirements. The Contractor shall be solely responsible for the safety of his personnel.

15. CEMENT SLURRY BACKFILL
If cement slurry backfill is required, cement slurry must be a fluid workable mixture of aggregate, cement, and water. The aggregate must be one of the following:

Waiver of subrogation. All insurance coverage maintained or procured pursuant to this agreement shall be endorsed to waive subrogation against CITY, its elected or appointed officers, agents, officials, employees and volunteers or shall specifically allow CONTRACTOR or others providing insurance evidence in compliance with these specifications to waive their right of recovery prior to a loss.

CONTRACTOR hereby waives its own right of recovery against CITY, and shall require similar written express waivers and insurance clauses from each of its sub consultants.

Enforcement of contract provisions (non estoppel). CONTRACTOR acknowledges and agrees that any actual or alleged failure on the part of the CITY to inform CONTRACTOR of non-compliance with any requirement imposes no additional obligations on the CITY nor does it waive any rights hereunder.

Requirements not limiting. Requirements of specific coverage features or limits contained in this Section are not intended as a limitation on coverage, limits or other requirements, or a waiver of any coverage normally provided by any insurance. Specific reference to a given coverage feature is for purposes of clarification only as it pertains to a given issue and is not intended by any party or insured to be all inclusive, or to the exclusion of other coverage, or a waiver of any type. If the CONTRACTOR maintains higher limits than the minimums shown above, the CITY requires and shall be entitled to coverage for the higher limits maintained by the CONTRACTOR. Any available insurance proceeds in excess of the specified minimum limits of insurance and coverage shall be available to the CITY.

City’s right to revise requirements.

The CONTRACTOR shall retain any and all rights provided either by Agreement or by law which pertain to the resolution of disputes and protests between the contracting parties.

ARTICLE 20. LIQUIDATED DAMAGES
Pursuant to Government Code Section 53069.85, if work is not completed within the contract time or in strict accordance with the Project Schedule, it is understood, acknowledged and agreed that the CITY will suffer damage.

If the CITY accepts work or makes any payment under this Agreement after a default by reason of delays, the acceptance of such work and/or payment(s) shall in no respect constitute a waiver or modification of any provisions regarding Contract Time, a completion schedule, the Project Schedule or the accrual of liquidated damages. In the event the same is not paid, the CONTRACTOR further agrees that the CITY may deduct the amount thereof from any money due or that may become due the CONTRACTOR under the Agreement. This Article does not exclude recovery of damages under provisions of the Contract Documents, and is expressly in addition to the CITY’s ability to seek other damages.

CONTRACTOR is to refer to Section Project Construction Schedule for duration of individual activities. Liquidated damages may be assessed if any individual activity duration exceeds the time indicated for that activity on the Project Construction Schedule.
