CITY OF SANTA ANA SPECIFICATIONS PROJECT NO.: 25-6030 TRAFFIC SIGNAL INSTALLATION AT SEGERSTROM AVENUE AND ROSEWOOD AVENUE If a conduit is bored or jacked across existing sewer mains or laterals, the contractor shall conform to the following requirements: 1. Pothole to determine location and depth of the sewer mains and laterals. 2. Visual confirmation by City Inspector shall be done during the boring/jacking of the conduit across the sewer mains or laterals for any damages prior to back filling the pothole. 3. If visual confirmation is not done, the contractor shall perform Video Inspection of Sewer Mains and Laterals per the following specifications. a. Video Inspection of Sewer Mains and Laterals The contractor shall use CCTV equipment to verify that City sanitary sewer mains have not been impacted. This includes all mains that appear on the plan of construction drawings as possible points of interference, regardless of the relative elevation of the sewer and what is believed to be the elevation of the newly constructed facility. The contractor shall use equipment specially designed and constructed for sewer inspection and televising. The camera must have light sources of suitable illumination output to provide a clear picture of the entire periphery of pipe. The camera must be able to be rotated to a position that will assure that the total periphery of the sewer is in focus at all times, regardless of the diameter of the pipe being inspected. The camera, transport system, and other components of the video system shall be capable of producing a picture adequate for the purposes of the inspection as stated herein. Video runs showing condensation or submersion of the lens, poor or out -of -focus images, poor audio, or otherwise poor image quality shall be cause for rejection and may necessitate re -televising at the consultant's expense if the City determines the video run is not of acceptable quality. A cable footage counter, accurate to within one (1) foot in 1000 feet, shall be used and shall be indicated on the monitor and recorded on the video. The date of inspection, continuous forward and reverse readout of camera distance from referenced access hole, the City supplied upstream and downstream manhole identification number with an arrow indicating the direction of flow, the size of the pipe, the name of the street, the time of day and the project or location name as supplied by the City shall be displayed continuously on the monitor and recorded on the video. The use of non-standard or incorrectly numbered manholes by the contractor on the video overlay is cause for rejection of the digital video and any costs associated with re-videoing of the main that are necessitated by the contractor's failure to use designated naming conventions will be borne entirely by the contractor. The footage relative to the center of the manhole at the start of each run shall be set to accurately reflect a center of manhole starting position of 0.00 feet regardless of where along the pipe and at what footage the run begins.
