Specifications include, but are not limited to: This project will assess the condition of the entire length of the SRO which is approximately 23 miles in length with pipe ranging in diameter from 54 to 90 inches. The project will also assess the condition of approximately 190 sanitary sewer manholes and structures. The scope of work will include, but not be limited to the following: • Review of past assessments of the SRO, past CCTV, as-builts of completed rehabilitation, and other pertinent documents and records. • Inspect the pipe interior, utilizing, but not limited to, video remote inspection equipment. The City prefers that the interior of the pipe be digitally scanned, but high flows and high velocities may prevent this method of inspection. • Inspect all manholes/structures on the interceptor. Standard manholes shall be inspected using digital technology that can scan the complete interior of the manholes. Manned entry may be necessary for structures/manholes in which digital technology does not provide satisfactory examination. Manned entry inspection will be required for at least 10% of the manholes/structures. • Assess pipe condition using NASSCO PACP and manhole condition using NASSCO MACP (Level 2). • Perform cleaning as necessary to inspect pipe. • Prepare detailed report of observations including recommendations for cost effective resolution of discovered defects. • Develop budgetary costs for high priority defects found in the pipeline and manholes/structures. • Hold progress meetings and workshops as needed to complete the work. • Update and input data for the WAM system. • Prepare a draft report for review. • Present the recommendations made in the draft report. • Prepare a final report. • Present a final executive summary.
