Public Works Bidding: A Guide for Commercial Contractors
Public works projects (federal, state, municipal, school district) are a huge slice of commercial construction — and they have their own rules. Get the compliance right and you'll have a steady pipeline; get it wrong and you'll be locked out of the market.
Prequalification and DBE requirements
Most public agencies require contractor prequalification before you can bid. Many also require DBE/MBE/WBE subcontractor goals. Build relationships with certified subs before you need them.
Prevailing wage compliance
Davis-Bacon (federal) and state prevailing wage laws set minimum wages by trade and county. Certified payroll reporting is mandatory and audited. Get a payroll service that handles it.
Bonding and insurance
Public works typically require 100% performance and payment bonds. Your bonding capacity is the ceiling on the size of public work you can pursue.
Bid day and award
Public bids are opened publicly and read aloud. Award goes to the lowest responsive, responsible bidder. Errors in bid forms (missing signatures, unacknowledged addenda) get bids thrown out — proofread everything.
Bid protests
If you lose a public bid you believe was awarded improperly, you have a narrow window (often 5–10 days) to protest. Know the procurement code in your jurisdiction.
