Contra Costa County in California is using this solicitation to procure paving work. Public buyers typically advertise this kind of work as an Invitation for Bids (IFB), Request for Proposals (RFP), or Request for Qualifications (RFQ), depending on whether the selection is price-driven, qualifications-driven, or both. Bidders responding to a paving solicitation in California are generally expected to provide proof of liability insurance and workers' compensation coverage, hold any state license or trade certification required for the scope of work, and post performance and payment bonds for contracts above the agency's threshold.
Federal-aid funding flowing through programs such as the Federal Highway Administration, FEMA, or the Infrastructure Investment and Jobs Act brings additional compliance requirements on solicitations like this one, including Davis-Bacon prevailing wage, Buy America provisions where applicable, and Disadvantaged Business Enterprise (DBE) participation goals set by the issuing agency. PublicBidSearch indexes this solicitation alongside other open bids in California so contractors and vendors can compare active opportunities by category, agency, or location without monitoring each procurement portal individually.
To submit a bid for this solicitation, review the full solicitation documents for Contra Costa County's exact scope of work, submission format, and any mandatory pre-bid meeting or site visit. Confirm how the agency accepts responses — through an electronic procurement portal, as a sealed hard-copy bid, or by email — because the required method varies by agency and a non-conforming submission can be disqualified. Direct questions about scope or specifications to purchasing@contracosta.ca.gov before the agency's question cut-off date. Vendors that have not previously contracted with Contra Costa County should confirm whether registration on the agency's vendor system is required to be eligible for award.
