displayed on the monitors as part of the video presentation and digital database image capture <br />system shall be the date of the survey, number designation of the upstream and downstream <br />manholes of the section being surveyed, and a continuous forward and reverse read-out of <br />the camera distance from the manhole of reference. At a minimum the laterals shall be <br />identified and clear inspection captured from the sewer main. <br />13. 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 />14. A primary goal of this inspection program is to accurately determine the quantity and location <br />of the building laterals or side sewers and conditions that appear unusual or uncommon to a <br />good sound sewer. The operating technician shall provide a verbal description and have <br />control of the movement of the television camera at all times. This may be accomplished by <br />means of remote control winches or by telephone or other suitable means of communication <br />between the winches at either end of the manhole section being surveyed. The travel speed <br />of the camera shall be uniform and shall not exceed 30 feet per minute or as would result in <br />video that could be comfortably viewed. Any means of propelling the camera through the <br />sewer that would exceed this rate of speed or produce non-uniform or jerky movements will <br />not be acceptable. The operating technician shall at all times be able to move the camera <br />through the line in either direction without loss of quality in the video presentation on the <br />monitor. The picture at all times shall be free of electrical interference and provide a clear, <br />stable image of the resolutions specified. <br />15. If during the inspection operation, the television camera cannot pass through the entire sewer <br />section due to an obstruction other than roots or grease, CONSULTANT shall set up his <br />equipment so that the inspection can be performed from the opposite manhole (reverse run). <br />If, again, the camera fails to pass through the entire pipeline section, the inspection shall be <br />considered complete and no additional inspection work will be required. The CONSULTANT <br />will be paid only the amount of lineal footage that was satisfactorily inspected, <br />recorded and submitted to the City. <br />16. The CONSULTANT shall provide digital database TV inspection reports, printed TV inspection <br />reports and MPEG -4 format color video of all work completed. The CONSULTANT shall <br />use the custom digital database TV inspection software WinCan Database System, version <br />7 or latest version. The Contractor shall be proficient in using WinCan software. Additionally, <br />the image capture system will include provisions for capturing both motion video and audio. <br />In other words, the complete interface system will allow the operator to record and store short <br />video movies of the sewer defects and include verbal audio when necessary. The operator(s) <br />shall be Pipeline Assessment Certification Program (PACP) certified. NASSCO PACP <br />format shall be used to assess the pipeline conditions. The inspections shall document <br />the following conditions and any other pertinent observations: <br />a. Cracks - radial and longitudinal, hairline or open; <br />b. Laterals (identify active or inactive, if possible) - quadrant location, protruding, <br />cracks, roots; <br />c. Corrosion - iron stains, roughened aggregate, exposed aggregate, exposed rebar, or <br />exposed soil; <br />d. Offsets/sags - 1 -inch, 2 -inch, 4 -inch, etc.; <br />e. Roots - light, moderate, heavy, or matted roots; <br />f. Grease - light, moderate, or heavy; <br />g. Infiltration - water stains, dripping water, or stream of water; <br />h. Other - holes in pipe, missing tile; <br />REV: 05-18-2021 VR <br />ATTY/AGR.2021.111/National Plant Services Inc. (Page 13 of 17) <br />
