CONTRACTOR shall call the Community Development Department Engineering and ` <br /> Transportation Division at(650)780-7380 to notify of the situation. i <br /> Lighting and camera quality shall be suitable to allow a clear n-focus picture for a minimum ; <br /> of sa lineal feet of the entire nside periphery of the sewer pipe. To ensure peak"picture <br /> qual�y throughout all conditions encountered during the survey, a variable intensity control <br /> of the camera lights and remote control adjustments for focus and iis shall be located at the ', <br /> monitoring station. Focal distance shall be adjustable through a range of from soc inches to i <br /> nfinity. Continuously displayed on the monitors as part ; <br /> of the video presentation and digital database inage capture system shall be the date of ` <br /> the survey, �umber designation of the upstream and downstream manholes of the <br /> section being surveyed, and a continuous forvvard and reverse read-out of the camera �. <br /> distance from the manhole of reference. � <br /> At the beginning of each manhole the footage counter shall be set at zero to accurately ' <br /> document the distance within the sewer line. ' <br /> A primary goal of this nspection program is to accurately dete�mine the quantity and ' <br /> location of the building laterals or side sewers and the existing pipe conditions that appear <br /> unusual or uncommon to a good sound sewer. The operating technician shail provide a <br /> verbal description and have cantrol of the movement of the television camera at all times. <br /> This may be accomplished by means of remote control winches or by telephone or other ; <br /> suitable means of communication between the winches at either end of the manhole <br /> section being sunreyed. The travel speed of the camera shall be uniform and shall not <br /> exceed 30 feet per minute or as would result n video that couid be comfortably viewed. <br /> Any means of propelling the camera through the sewer that would exceed this rate of <br /> speed or produce �on-uniform or jerky movements will not be acceptable. The operating <br /> technician shall at ali times be able to move the camera through the ine n either direction <br /> without bss of qual�y n the video presentation on the monRor. The picture at all times <br /> shall be free of electrical interference and provide a clear, stable inage of the : <br /> resolutions specified. <br /> Zf during the hspection operation the television camera cannot pass through the entire <br /> sewer section due to an obstruction other than roots or grease, CONTRACTOR shall set <br /> up his equipment so that the inspection can be performed from the opposite manhole <br /> (reverse run). If, again, the camera fails to pass through the entire pipeline section, the <br /> nspection shali be considered complete and no additional inspection work will be <br /> required. The CONTRACTOR will be paid only the amount of lineal footage that was <br /> nspected. <br /> PACP pipe ratings shall be included for each pipe segment nspected. All videos shall be <br /> of good qual�y MPEG-4 format and shall clea�ly show the above stated conditions. <br /> The date, identification of sewer section by upstream and downst�eam manhole <br /> locations,and footage shall be displayed on the video data view at all times. <br /> The hspection will be recorded digitally to an extemal hard drive and shall become <br /> property of the C�y. At the beginning of each inspection,the information of the inspection <br /> shall be displayed'n the following PACP format: <br /> A. Surveyed By <br /> B. Street <br /> C. Locations Code <br /> D. D�ection of nspection <br /> E. Pipe material <br /> F. Pipe diameter <br /> G. Length of reach to be televised <br /> H. Manhole numberfrom which the camera istraveling <br /> I.
