Page 2 of 3 agreement with Pakpour Consulting Group to design the Bernal Avenue 18-Inch Water Main (F-4 Line) Project, CIP No. 24172. This project was combined with city staff-designed Turnout No. 1 improvements into a single construction package and competitively bid in November 2023. On January 16, 2024, the City Council awarded a construction contract to Golden State Construction & Utility, Inc. In the amount of $1,644,000 and authorized the director of Public Works to approve contract change orders up to the project contingency amount of $247,000. Construction began in February 2024 and was successfully completed in January 2025. DISCUSSION Due to the restricted water service from Wells 5 and 6 due to PFAS, additional water is being purchased from Zone 7 through existing turnouts to meet system demands. Following the completion of the Water Supply Alternatives Study, the City Council selected a project to construct two new groundwater wells on the west side of the City. To meet the City’s future and short-term water demands until the new wells are in service and to rebalance the water system, improvements to turnouts and water distribution piping are necessary. The Bernal Avenue 18-Inch Water Main (F-4 Line) & Turnout No. 1 Improvements Project, CIP No. 24172, is the first of three capital improvement projects required to maintain balanced water system pressure in response to the limited availability of water from city-owned wells, to meet future demands, and to improve reliability of the system. Improvements to Turnout No. 1 included replacing the internal piping, flow meter and control valve, and installing a pressure-regulating valve to protect the turnout and update the facility to current standards. Vault repairs to address corroded rebar and the installation of a flushing and sampling hydrant were also included in the project. The City pre-purchased the flow meter and valves due to the long lead time for the materials. These improvements are necessary to ensure the reliable and long-term operation of the turnout. In addition, a Zone 7 valve used to isolate Turnout No. 1 to perform the project work failed and was replaced under the contract and reimbursed by Zone 7. On-call contractors were used to replace traffic loops, perform material testing for the project and provide structural review and recommendations for repairs to the vault walls. All work performed by Golden State Construction & Utility, Inc. has been reviewed and verified by the City Engineer to meet the City’s approved plans and specifications and has been completed to the satisfaction of the Director of Public Works. Staff recommends the City Council accept the work, authorize the City Clerk to file a Notice of Completion, and authorize the release of the retention 30 days after recordation. EQUITY AND SUSTAINABILITY The City’s Procurement Policy for purchasing procedures was followed. OUTREACH Notices were sent to adjacent residences and businesses prior to the start of construction and posted on the City’s website. Page 154 of 249
