CONTRACTOR shall take at least one picture of all mid-to-major defects in pipe that will be in JPEG
<br /> format. Each JPEG file will be named in accordance with the line and footage. One photograph shall also
<br /> be taken of each lateral connection looking up into the lateral.
<br /> CONTRACTOR shall setup at the upstream manhole whenever possible to video inspect with the flow.
<br /> The camera will move at a uniform rate at a speed no greater than 30 feet per minute. Distance of the line
<br /> will be measured and recorded from the center of manhole to the center of the next manhole. The
<br /> distance will be accurate within 2 feet of every 1000 linear feet inspected. If more than one manhole
<br /> reach is inspected in a single run, the footage counter shall be reset to zero at the center of all
<br /> intermediate manholes. The camera shall pause for a sufficient amount of time to adequately document
<br /> and provide accurate distance measurements of all defects in pipe and the connections observed in the
<br /> line. The camera shall rotate and look directly at each defect and look into each connection to thoroughly
<br /> document the conditions and determine if the lateral is in service. CONTRACTOR shall capture photos of
<br /> any moderate and above damages or abnormal conditions.
<br /> The recording shall include an audio portion describing the condition of the lines with the video image.
<br /> The audio portion will be sufficiently free of background noise to produce an oral report that clear and
<br /> easily discernible. At the beginning of each inspection run, the audio shall identify CONTRACTOR'S
<br /> name, the crew member, date, time, street location, name of line, pipe size, pipe material, direction of
<br /> inspection, and the pipe numbers at the beginning and end of the reach. The audio shall note during the
<br /> inspection the location and condition of the pipe defects, including all cracks, breaks, cracked or
<br /> misaligned joints, root intrusion, infiltration, missing pieces of pipe, corrosion, deposits, obstructions, and
<br /> any other items which reflect the condition of the sewer line. The audio shall also note the location of the
<br /> connections, and whether the connection is in service. All observations shall be included on the
<br /> inspection report.
<br /> Continuous digital recordings of the inspection view as it appears on the monitor shall be stored. A digital
<br /> recording will be made of the entire inspection. The video will be recorded in MPEG 4 unless prior
<br /> arrangements are made between the City and CONTRACTOR.
<br /> In case the camera cannot pass from upstream to downstream,a reverse setup will be attempted. In case
<br /> of this type of setup, a separate MPEG file will be stored. Inspection data shall be obtained using WinCan
<br /> software. This shall include data tables, observations, pictures, and video. CONTRACTOR shall use
<br /> standard observation codes consistent with PACP coding. Once all inspections are complete,
<br /> CONTRACTOR shall give the City of Redwood City a hard drive that details all of the captured
<br /> information, and WinCan reader program that has full rights for viewing all videos, pictures, and
<br /> observations.
<br /> The CONTRACTOR shall provide digital database TV inspection reports, printed TV inspection reports
<br /> and MPEG-4 format color video of all work completed. The Contractor shall use the custom digital
<br /> database TV inspection software WinCan Database System, version 8.30.0.2090 The Contractor shall be
<br /> proficient in using WinCan software. Additionally, the image capture system will include provisions for
<br /> capturing both motion video and audio. In other words, the complete interface system will allow the
<br /> operator to record and store short video movies of the sewer defects and include verbal audio when
<br /> necessary. The operator(s) shall be Pipeline Assessment Certification Program (PACP) certified.
<br /> NASSCO PACP 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
<br /> rebar, or 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;
