For capital projects, bidders need to follow bidding instructions carefully and be sure make all submissions prior to the project's submission deadline.
The County opens all Bids (envelopes or electronic) promptly following the submission deadline and initially evaluates them for responsiveness, and to determine an Apparent Low Bidder. The Sonoma County Director of Transportation & Public Works then reviews the bids and refer them to the Board of Supervisors to consider awarding the project. The review process is complete within 60 days of the bid opening.
Bidders can obtain Bidding Documents at no charge by registering at Sonoma County's Supplier Portal, the County's online procurement system:
