EXHIBIT A <br /> SCOPE OF WORK. DEADLINE AND PAYMENT TERMS <br /> PROJECT DESCRIPTION: <br /> Closed circuit television (CCT� inspection and cleaning for that purpose, of selected pipelines in sanitary <br /> sewer basins 4, 5C, and 9. <br /> SCOPE OF WORK: <br /> Cleaning <br /> CONTRACTOR shall use a jet/vacuum combination unit for cleaning all sewer lines. The combination unit <br /> shall operate at 80 gallons per minute at a pressure of 2,500 psi, and be equipped with approximately 800 <br /> linear feet of hose. CONTRACTOR'S operating technicians shall have a minimum of 3 years of <br /> experience cleaning with this piece of equipment. CONTRACTOR shall procure water meter(s) from the <br /> appropriate water district for the appropriate fee. CONTRACTOR shall clean the lines in a downstream <br /> direction, beginning from the most upstream manhole of a particular reach or set of reaches, and begin <br /> cleaning so that the debris will continually be pulled downstream. <br /> In order to jet clean the lines, a high pressure water pump on the combination truck shall deliver water <br /> from attached tanks through a high pressure hose to a cleaning nozzle. The water pumped through the <br /> cleaning nozzle shall propel the nozzle and attached high pressure hose through the sewer. Once the <br /> cleaning nozzle has arrived at an upstream manhole, the nozzle shall be pulled back through the pipe at <br /> a velocity controlled by the operator. During the cleaning process, the cleaning nozzle will not travel faster <br /> than one foot per second in the line. While the cleaning nozzle is pulled back, the vacuum system shall be <br /> used to simultaneously remove debris flushed by the cleaning nozzle. <br /> CONTRACTOR shall use a root cutting nozzle to remove all debris. The root cutting nozzle shall revolve <br /> 360 degrees, be capable of cleaning at 6"-26° lines, and operate at 80 gallons per minute at a pressure of <br /> 3,000 pounds per square inch. Dislodged roots shall be captured and removed from the line either by the <br /> vacuum or a basket. <br /> CCTV Inspection <br /> Within 24 hours of cleaning the line, CONTRACTOR shall thoroughly inspect the sewer lines using CCTV <br /> equipment and WinCan V8 inspection software. The CCTV camera and monitor shall produce a minimum <br /> of 460 horizontal lines of resolution. The CCTV camera shall be a pan-and-tilt with rotating head capable <br /> of providing a 360-degree view of the inside of all pipes, connections, and any pipe defects. Video <br /> recording shall be done digitally in full color in order to provide the utmost quality viewing. Images will be <br /> in focus and done with adequate lighting to provide a clear view of the entire periphery of the line <br /> including any defects while keeping glare to a minimum. The image shall not be obscured by fogging or <br /> misting conditions when in a sewer line. <br /> The inspection will be recorded digitally to an external hard drive and shall become property of the City. <br /> At the beginning of each inspection, the information of the inspection shall be displayed in the following <br /> PACP format: <br /> A. Surveyed By <br /> B. Street <br /> C. Locations Code <br /> D. Direction of inspection <br /> E. Pipe material <br /> F. Pipe diameter <br /> G. Length of reach to be televised <br /> H.
