FISCAL IMPACT:
$591,600 (68%) be funded through Measure X Funds, $182,700 (21%) will be funded through the California State Library Building Forward Grant (SB 129), and $95,700 (11%) will be funded through Library Funds.
BACKGROUND:
This project will upgrade the electrical system, upgrade interior lighting and provide accessibility improvements at the Antioch Library located at 501 W. 18th Street, Antioch.
The facility is an 11,225 square foot building constructed in 1967 with what is now an antiquated electrical system. The upgrades include installing a new higher capacity electrical switchboard and additional service outlets on the main library floor to serve library patrons’ needs for powering their personal electronics. Interior lighting upgrades include replacing fluorescent fixtures with more energy-efficient light emitting diode (LED) fixtures to be in line with the County’s Climate Action Plan. The project also includes accessibility upgrades as triggered and required by the 2022 California Building Code.
On March 11, 2025, the Board of Supervisors approved the design and bid documents for the construction of the Project and authorized the solicitation of bids in accordance with Public Contract Code Section 22037. Bids were received and opened by the Public Works Department on June 5, 2025.
On July 22, 2025, This Board approved the rejection of the submitted bids due to unresponsive GFE packages and approved the re-advertisement of this project. Bids were received on September 10, ,2025 and the bid results are as follows:

The Public Works Department staff has thoroughly reviewed the bids and determined that Vantis's bid is responsive and that Vantis has documented an adequate good faith effort to comply with the requirements of the County's Outreach Program, as provided in the Project specifications. Staff recommends that the construction contract for this Project be awarded to Vantis, the lowest, responsible bidder, in the amount of $870,000, as listed in Vantis's bid.
CONSEQUENCE OF NEGATIVE ACTION:
Without the Board of Supervisors approval, the project will not be constructed, the electrical system will remain out of date and insufficient for modern power requirements in libraries, the lighting will not be energy efficient and aligned with the County's Climate Action Plan, and the parking lot will not meet accessibility standards.
