EXHIBIT A "Sewer&Storm Flushing&CCTV Services" Bid#OSD 2021-603 defects to be viewed directly.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. 12. At the beginning of each manhole the footage counter shall be set at zero to accurately document the distance within the sewer/storm line. 13. A primary goal of this inspection program is to accurately determine the quantity and location of the building laterals or side sewers and conditions that appear unusual or uncommon to a good sound sewer. The operating technician shall provide a verbal description and have control of the movement of the television camera at all times. 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/storm that would exceed this rate of speed or produce non-uniform or jerky movements will not be acceptable.At all times,the operating technician shall be able to move the camera through the line in either direction without loss of quality in the video presentation on the monitor. At all times, the picture shall be free of electrical interference and provide a clear,stable image of the resolutions specified. 14. If during the inspection operation the television camera cannot pass through the entire sewer/storm section due to an obstruction other than roots or grease, CONTRACTOR shall set up their 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. 15. The CONTRACTOR shall provide digital database TV inspection reports, printed TV inspection reports and MPEG-4 format color video of all work completed. Inspection data must be geo-coded and referenced so the City can tie back to its GIS system.The City will provide the system mapping data.The Contractor shall use TV inspection software and data storage system, which is directly compatible with WinCan Database System, version 8 or, latest version or, equivalent. Additionally, the image capture system will include provisions for capturing both motion video and audio. In other words, the complete interface system will allow the operator to record and store short video movies of the sewer/storm defects and include verbal audio when necessary. The operator(s) shall be Pipeline Assessment Certification Program (PACP/MACP)certified.NASSCO PACP/MACP format shall be used to assess the pipeline conditions. The inspections shall document the following conditions and any other pertinent observations: a. Cracks- radial and longitudinal, hairline or open. b. Laterals (identify active or inactive, if possible) - quadrant location, protruding, cracks, roots. c. Corrosion- iron stains, roughened aggregate, exposed aggregate, exposed rebar, or exposed soil. d. Offsets/sags - 1-inch, 2-inch, 4-inch, etc. e. Roots- light, moderate, heavy, or matted roots.
