CITY OF SANTA ANA RFP NO.: 24-003 CLOSED CIRCUIT TELEVISION (CCTV) INSPECTION OF SANITARY SEWERS through the infraMAPO software, will designate the locations that are to be inspected. Use of the infraMAPO software by the Contractor is required. The City shall train the Contractor in the use of infraMAPO as it relates to the documentation of sewer cleaning and inspection activities. 8. If the Contractor encounters conditions in the field that do not correspond to those indicated on the maps, the Contractor shall promptly inform the City of the discrepancy. If manholes or terminating cleanouts are encountered that are not shown on the maps, the Contractor shall use the next available manhole number as shown on the maps for the video assessment and indicate the location where the manhole was found. The City will incorporate those changes into the maps. The use of non-standard or incorrectly numbered manholes by the Contractor in either the database or on the video overlay as shown on the digital video is cause for rejection of both the digital video and the database in which it is referenced and any costs associated with re-videoing of the main, modifications to the video overlay or rectification of the database that are necessitated by the consultant's failure to use designated naming conventions will be borne entirely by the Contractor. 9. At all points within the sewer showing defects, laterals and sewer appurtenances, the consultant shall stop the camera, rotate (up to 360 degrees) and/or tilt the camera lens to ensure adequate video coverage. All defects shall be rated/scored and logged in accordance with NASSCO guidelines. 10. The camera shall be stopped and/or backed up to view and analyze conditions that appear unusual or uncommon to a sewer main in good condition. There shall be no loss of video quality at any time. 11. As the video is produced, the technician shall provide an audio narration of the inspection to include identification of the sewer main location, by street intersection location or street address as well as by City manhole number, inspection direction (upstream/downstream) and complete descriptions of the line conditions as they are encountered. The audio portion of the video recording shall be free from electrical interference, feedback, hum, and background noise. 12. If the camera cannot pass the entire sewer reach from its point of insertion, the reach shall be inspected from both directions. The inspection logs for the reach shall include an identification of the nature and location of the blockage. The Contractor shall notify the City immediately of any such obstruction so that it may be repaired or mitigated by the City and/or the Contractor so that work may proceed. 13. Video runs showing condensation or submersion of the lens, poor or out -of -focus images, poor audio, or otherwise poor image quality shall be cause for rejection and may necessitate re -inspecting at the Contractor's expense if the City determines the video run is not of acceptable quality. 14. In special cases, when directed by the City, the Contractor shall be responsible for plugging manhole outlets during CCTV inspection. The sewer lines will be in service at City of Santa Ana RFP 24-003 Closed Circuit Television (CCTV) Inspection of Sanitary Sewers Page 17
