CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: 25-6030 TRAFFIC SIGNAL INSTALLATION AT SEGERSTROM AVENUE AND ROSEWOOD AVENUE 13. Schedule for installation of and maintenance of bypass pumping piping. 14. Submit a sewer overflow emergency response plan. The plan will dictate backup pumping plans, spill containment procedures, spill recovery procedures and emergency call out phone numbers. Provision shall be made by the Contractor for the collection of sewage from cutoff lateral sewers. Lateral sewers shall be reconnected to the main before the termination of every working day. The text of Subsection 306-1.6 of the Standard Specifications is hereby deleted and replaced with the following: Pipe shall be measured along the longitudinal axis between the ends as laid and shall include the actual pipe in place. Following placement and compaction of backfill and prior to the placement of permanent pavement, all newly constructed PVC sewer mains shall be cleaned and tested for deflection and ovality by either using: a rigid mandrel for smaller diameter pipe; or laser profile technology and/or with an electronic deflect-o-meter for larger diameter piping. The deflection and or ovality shall not exceed (5%) of the inside diameter of the pipe. If the pipe exceeds this tolerance, it is the responsibility of the contractor to replace and re- test the newly constructed pipe for deflection and ovality. If the pipe is to be tested by mandrel, the rigid mandrel shall have a circular cross section having a diameter of at least 95 percent of the specified inside pipe diameter and shall be pulled through the pipe by hand. The minimum length of the circular portion of the mandrel shall be equal to the nominal diameter of the pipe. A 1/4-inch diameter nylon line shall be pulled from manhole to manhole and shall be left for use in conducting the CCTV inspection. Obstructions encountered by the mandrel shall be repaired and the pipeline section shall be retested. All labor and equipment necessary to conduct these tests shall be furnished by the contractor. The contractor shall submit all laser profile documents to the Engineer for review and approval no later than(10) days after the test. 6.11 NEW MANHOLE STRUCTURES Construction of new concrete manhole structures shall be done in accordance with City of Santa Ana Standard No. 1201, details as shown on the plans, the applicable provisions of Sections 201, 303, and 306 of the Standard Specifications and these Special Provisions.
