EXHIBIT A PROPOSED SCOPE OF SERVICES — TELEVISION INSPECTION OF SANITARY SEWERS The purpose of this proposal is to obtain a qualified firm to provide sewer video taping services. This project continues the video inventory of the city's sewer infrastructure. The majority of the work will consist of videotaping and cleaning individual sewer mains on an as needed basis. However, some of the work will also include the videotaping and cleaning of blocks of sewer mains (approximately 3,000 to 7,000 linear feet. The sizes of the lines to be videotaped vary from 4" up to 24" in diameter. The majority of the work will be performed on mains in the 6" through 12" range with more than 50% of the total work being 6". A. SEWER CLEANING: All sewers shall be cleaned within 24 hours prior to videotaping except as directed otherwise by the Engineer. Cleaning shall include removal of grease, roots, debris and other obstructions to facilitate the T.V. inspection. Consultant shall use the appropriate nozzle or cutter head, (e.g. high velocity, water jet, root cutter, etc.), to accomplish the cleaning as required for that particular reach of sewer. Cleaning methods shall be employed to sufficiently clean the pipe so the camera can pass and can fully ascertain and document the structural and operational condition of the pipe. Any costs associated with videotape work that is necessitated by the consultant's failure to sufficiently clean the main shall be borne entirely by the consultant. The consultant shall use a maintenance report form supplied by the City to record the location of the cleaning operation, the number of feet cleaned and the conditions encountered for each section of sewer main that is cleaned. The maintenance reports shall be delivered along with the video, logs and other materials when a designated area of work has been completed. B. TELEVISION INSPECTION: The consultant shall visually inspect, videotape (VHS format) and/or digitally encode (in WMV format), and provide both written and computerized logs of all inspected sewers. The log and video formats shall be approved by the City prior to commencement of work. 2. The consultant shall use equipment specially designed and constructed for sewer inspection and televising. The camera must have light sources of suitable illumination output to provide a clear picture of the entire periphery of pipe. The camera must be able to be rotated to a position that will assure that the total periphery s
