Executive Summary:
This item requests approval of a contract with Myers & Sons Construction for construction of the Wilfred Booster Station Resiliency project (Project). The project will replace existing outdated electrical and mechanical systems, add pumping redundancy, and upgrade instrumentation, process, and control systems at the booster station.
Discussion:
Wilfred Booster Station is part of the Sonoma County Water Agency’s (Sonoma Water) water transmission system that supplies drinking water to residents and businesses in Sonoma and Marin Counties. The station is located at 4980 Commerce Boulevard in Rohnert Park, California along the Petaluma Aqueduct and was originally constructed in 1974. Over its useful life, the station has helped maintain adequate pressure in the Petaluma Aqueduct and has the unique capability of being able to pump north or south along the aqueduct providing much needed resiliency within the transmission system during periods of construction or emergencies when other portions of the system may be temporarily out of service. The existing booster station has reached the end of its useful life and needs to be replaced.
The Wilfred Booster Station Resiliency project consists of demolition of the existing medium voltage switchgear and installation of owner-furnished medium voltage switchgear; demolition and replacement of the existing booster pump with a new booster pump; installation of a secondary booster pump and associated valves and piping to provide redundancy; and upgrades to the control system for operating the facility. Work shall be completed within 610 days of contract commencement.
The engineer’s estimate was $6,651,000.00. The Project was advertised for bids on August 14, 2025.
On October 7, 2025, seven responsive bids were received per the attached Bid Summary. The lowest responsive and responsible bid is from Myers & Sons Construction and is $158,340 above the Engineer’s Estimate. Myers & Sons Construction is experienced in this type of construction and meets the experience requirements.
A contractor must execute a release of claims (Section 00 65 23) before final payment but may except any unresolved claims from the release. The requested action authorizes the General Manager to approve the release unless the contractor lists unresolved claims. In that case, County Counsel must review Section 00 65 23 prior to General Manager approval.
Construction on the Project is scheduled to begin approximately January 2026, with an estimated completion date of September 2027.
California Environmental Quality Act
The General Manager has determined that the project is exempt from the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Sections 15301, Existing Facilities, 15302, Replacement or Reconstruction, and 15304, Minor Alterations to Land, 15301. The project is exempt because the replacement and upgrade of existing facilities would involve no expansion of use, and would not remove healthy, mature, or scenic trees.
