Administration Building Boiler Replacement Project (2/25 Revision)

Tuolumne County, through its General Services Agency, is seeking qualified vendors to execute the Administration Building Boiler Replacement Project located at 2 S. Green Street in Sonora, California. The procurement involves removing an existing diesel-powered boiler and replacing it with a new electric AERCO Benchmark E Series boiler, specifically the 216-684 kW model with Edge Controller. Contractors must possess C-4 and C-10 Contractor's Licenses and be registered with the Department of Industrial Relations. The project requires complete boiler removal, disposal, installation of the new electric boiler, and site restoration, with a total contract duration of four months and potential thirty-day extensions. Bidders must submit electronic proposals by 8:00 am on Tuesday, March 25, 2025, through the county's e-Procurement platform, with a mandatory pre-proposal meeting scheduled for March 14, 2025, at 10:00 am. Evaluation will focus on responsiveness, contractor qualifications, and pricing, with the county reserving the right to reject any or all bids. A bidder's bond or security of at least ten percent of the bid amount is required, with payment and performance bonds mandatory for contracts exceeding $25,000.

The contract appears to have no specific set-aside designations for disadvantaged enterprises, but does require strict compliance with prevailing wage rates and various labor regulations. Bidders must submit multiple certifications, including debarment, suspension, and noncollusion declarations, demonstrating a comprehensive vetting process. The existing infrastructure involves the county administration building's current HVAC systems, with technical documentation including historical mechanical drawings from 1979 and recent electrical load calculation spreadsheets. While a specific budget range is not explicitly stated, the project's complexity and requirements suggest a significant capital investment. The electric boiler specifications indicate modern capabilities including zero emissions, peak load management, and compatibility with building automation systems, suggesting the county is investing in energy-efficient and technologically advanced infrastructure upgrades. The county will award the contract to the lowest responsive bidder, subject to fund availability, with the potential for future contract extensions.
