REQUEST FOR PROPOSAL TELEVISION INSPECTION OF SANITARY SEWERS The City of Santa Ana is soliciting proposals from qualified firms for the cleaning, television inspection and video recording, by means of a closed circuit color television camera, of approximately 300,000 linear feet of sanitary sewer mains. This work shall include cleaning of sewer mains prior to videotaping. PROPOSED SCOPE OF SERVICES — TELEVISION INSPECTION OF SANITARY SEWERS The purpose of this proposal is to obtain a qualified firm to provide sewer video recording services. This project continues the video inventory of the city's sewer infrastructure. The majority of the work will consist of videoing individual sewer mains on an as needed basis. However, some of the work will also include the videoing and cleaning of blocks of sewer mains (approximately 3,000 to 10,000 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 videoing 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 video 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. The City reserves the right to use both the comprehensiveness and completeness of the cleaning reports along with the cleanliness of the pipe as evidenced by the supplied video to ascertain whether to pipe was cleaned sufficiently. Any costs required 8
