Mechanical Work/HVAC Job Order Contracts (JOC 2707-2709) - Class C20 License

San Mateo County's Department of Public Works is requesting proposals for Mechanical Work/HVAC Job Order Contracts (JOC 2707-2709) under a Class C20 license, with a mandatory pre-proposal meeting on November 18, 2026 and electronic proposals due December 10, 2026 at 2:00 p.m. Bidders must maintain a staffed office within San Mateo County or within 55 miles of the County Center, and contractors not represented at the pre-proposal meeting will be deemed non-responsive.

The County will contract with up to three contractors to provide all labor, materials, tools, equipment, and related items for mechanical and HVAC work within a designated County area. If the need arises, the Owner may require work at any location under County jurisdiction. Work is issued through separate job orders with notices to proceed, and all work is subject to California prevailing wage requirements. Compensation is set by seven base adjustment factors applied to preset unit prices in the Construction Task Catalog, covering normal and other-than-normal hours for general, detention, and HCAI facilities, plus a PLA Compliance Adjustment Factor. A 1 percent JOC System License Fee applies to all job orders.

Bidders must hold an active Class C-20 license, show five years of continuous experience as prime on comparable municipal projects valued between $100,000 and $1.0 million, and have completed three similar projects. A $25,000 bid bond is required with submission. Upon award, contractors must furnish $1.0 million performance and payment bonds, increasing to 100 percent of the $5.0 million maximum contract value if job orders exceed $1.0 million. Workers' compensation, comprehensive general liability, and motor vehicle liability insurance must be maintained throughout the term.

Each agreement carries an aggregate fiscal obligation not to exceed $5.0 million for a maximum individual term of one year. The contract is indefinite quantity with no guaranteed minimum volume, and the target start date and term are subject to negotiation of a final agreement.

The apparent lowest, responsive, and responsible bidder is selected for each contract and excluded from consideration for each successive contract. Question deadline is November 30, 2026, with responses due December 4, 2026, and anticipated award is January 26, 2027.
