Woods Construction Inc. of San Francisco, California for their responsive and responsible low base bid of $928,800.00; authorize the City Manager to execute the contract and increase the contract amount, if necessary, up to 10% of the amount awarded, not to exceed $1,021,680.00 and confirm determination that the project is exempt and meets California Environmental Quality Act (CEQA) exemption criteria as set forth in Section 15301 (Existing Facilities) and Section 15302 (Replacement or Reconstruction) of the CEQA Regulations. BACKGROUND The City systematically replaces sections of aging sewer infrastructure to ensure the continued reliability of the system. Each year, staff identifies pipelines that require excessive maintenance or experience repeated service disruptions and targets those pipelines for improvement. CCTV inspection review of Sanitary Sewer Basin Nos. 5B, 5F and 5H were completed in 2014. Staff's review of the inspection videos revealed numerous defects in these sewer basins. A number of construction options for repair/rehabilitation have been evaluated by Staff to determine the most cost-effective method of mitigation. For this project, a "cured in place" lining method has been chosen in order to replace the identified pipe defects. The proposed sanitary sewer rehabilitation project will improve the condition of, and minimize infiltration and inflow into the sewer collection system. This project will rehabilitate approximately 6,457 linear feet of existing 6-inch and 8-inch sanitary sewer main, rehabilitate 42 existing sanitary sewer manholes and replace 161 existing sanitary sewer laterals. Some pipe defects, particularly those resulting in pronounced misalignment will be excavated and repaired. In order to complete this work, an outside contractor must be hired. The following report details the result the bids recently received to complete this work, as well as the recommended contractor.
