Lighting and camera quality shall be suitable to allow a clear in -focus picture for a minimum of six lineal feet of the entire inside periphery of the sewer and/or storm pipeline. To ensure peak picture quality throughout all conditions encountered during the survey, a variable intensity control of the camera lights and remote control adjustments for focus and iris shall be located at the monitoring station. Focal distance shall be adjustable through a range of from six inches to infinity. Continuously displayed on the monitors as part of the video presentation and digital database image capture system shall be the date of the survey, number designation of the upstream and downstream manholes of the section being surveyed, and a continuous forward and reverse read-out of the camera distance from the manhole of reference. At the beginning of each manhole the footage counter shall be set at zero to accurately document the distance within the sewer and/or storm pipelines. A primary goal of this inspection program is to accurately determine the quantity and location of the building laterals or side sewers and/or storm pipelines and the existing pipe conditions that appear unusual or uncommon to a good sound sewer and/or storm pipelines. The operating technician shall provide a verbal description and have control of the movement of the television camera at all rimes. This may be accomplished by means of remote control winches or by telephone or other suitable means of communication between the winches at either end of the manhole section being surveyed. The travel speed of the camera shall be uniform and shall not exceed 30 feet per minute or as would result in video that could be comfortably viewed. Any means of propelling the camera through the sewer and/or storm pipelines that would exceed this rate of speed or produce non-uniform or jerky movements will not be acceptable. The operating technician shall at all times be able to move the camera through the fine in either direction without loss of quality in the video presentation on the monitor. The picture at all times shall be free of electrical interference and provide a clear, stable image of the resolutions specified. If during the inspection operation the television camera cannot pass through the entire sewer and/or storm pipelines section due to an obstruction other than roots or grease, Contractor shall set up his equipment so that the inspection can be performed from the opposite manhole (reverse run). If, again, the camera fails to pass through the entire pipeline section, the inspection shall be considered complete and no additional inspection work will be required. The Contractor will be paid only the amount of lineal footage that was inspected. PACP pipe ratings shall be included for each pipe segment inspected. All videos shall be of good quality MP4 video format and shall clearly show the above stated conditions. The date, identification of sewer section by upstream and downstream manhole locations, and footage shall be displayed on the video data view at all times. Manhole assessment shall be included for each manhole inspected. All videos shall be of good quality MP4 video format and shall clearly show the manhole conditions (i.e. infiltration, root intrusion, structural defects, etc, of the manhole's frame/cover, cone and channenase). Contractor shall provide an approved manhole inspection log for each manhole inspected. The inspection will be recorded digitally to an external hard drive and shall become property of the City. At the beginning of each inspection, the information of the inspection shall be displayed Page 9 of 14 REV: 06-29-18 PR ATTY/AGR.2018.148/National Plant Services, Inc.
