CITY OF SANTA ANA <br /> SPECIFICATIONS <br /> PROJECT NO.: 25-6030 <br /> TRAFFIC SIGNAL INSTALLATION AT SEGERSTROM AVENUE AND ROSEWOOD <br /> AVENUE <br /> Individual pipe sections shall not be stacked in piles higher than five feet. The pipe shall <br /> not be stored next to heat sources or engine exhausts. All gaskets should be protected from <br /> heat, oil and grease. <br /> Field cutting of PVC pipe shall be square cut and bevel the end with a beveling tool. <br /> Remove all burrs and raised edges prior to assembly. <br /> Potholing shall be considered as part of the excavation necessary for the work. The <br /> Engineer shall be given the opportunity to inspect the existing improvement when it is <br /> exposed. <br /> Any adjustments in line or grade which will be necessary to accomplish the intent of the <br /> plans shall be made. In the event obstructions are encountered during the progress of the <br /> work which will require alterations to the plans, the Engineer shall have the authority to <br /> change the plans and order the necessary deviation from the line or grade. Contractor shall <br /> not make any deviation from the specified line or grade without approval by the Engineer. <br /> Pipe sections shall not be deflected at any joint, either vertically or horizontally, beyond <br /> the limits specified by the manufacturer. <br /> The pipe and fittings shall be lowered into the trench. Do not throw the pipe or fittings into <br /> the trench. <br /> If it is determined that bypassing of sewer flow will be required, the bypass pumping <br /> system shall have sufficient capacity to pump the peak flow. Sewer bypassing shall <br /> conform to Section 6-21 of these Special Provisions. The Contractor shall provide bypass <br /> piping for the effluent during the construction of the sewer main between manholes. The <br /> inlet of the downstream manhole and the outlet of the upstream manhole shall be plugged. <br /> A portable pump shall be installed in the upstream manhole to discharge the effluent from <br /> the upstream manhole to the downstream manhole through the bypass piping. Pump and <br /> bypass piping shall be of adequate size and capacity to handle the flow without sewage <br /> backup occurring to facilities connected to the sewer. <br /> For sewers 12-inches in diameter and larger, or where deemed necessary by the City, the <br /> following shall apply: <br /> All pumps used shall be fully automatic self-priming units. All pumps used must be <br /> constructed to allow dry running for long periods of time to accommodate the cyclical <br /> nature of effluent flows. The Contractor shall provide the necessary stop/start controls for <br /> each pump. The Contractor shall have adequate standby equipment available and ready <br /> for immediate operation and use in the event of an emergency or breakdown. One standby <br /> pump for each size pump utilized shall be installed at the mainline flow bypassing <br /> locations, ready for use in the event of primary pump failure. The Contractor shall <br /> continually monitor all pumping equipment. <br /> 95 <br />
