How to Bid Government Construction Contracts

Government construction work runs 8 to 12% of total US construction spending in 2026, or roughly $180 to $240 billion per year across federal, state, and local agencies. The work is steady, the pay is reliable, and the contracts are long-term enough to plan crew schedules around. The trade-off is process. Government bids require more paperwork than private work. Bonding requirements are higher. Prevailing wage rules apply on most federal and many state jobs.

SAM.gov is the federal portal for contractor registration and opportunity search. Registration is free. You need an Employer Identification Number, a bank account, and your business address. First-time registration takes 7 to 14 days. Renewal is annual. During registration, you select NAICS codes that describe your work. Construction trades typically use NAICS 23xxxx codes.

Set-asides are federal contracting categories that restrict competition to specific small business types. Main categories: Small Business, 8(a) Business Development, HUBZone, Service-Disabled Veteran-Owned Small Business, Women-Owned Small Business. Qualifying for a set-aside opens specific opportunity pools where you compete only against other set-aside firms.

• Small Business: revenue under NAICS size standard.
• 8(a): socially and economically disadvantaged ownership.
• HUBZone: business in a HUBZone with 35% local hires.
• SDVOSB: 51% ownership by service-disabled veterans.
• WOSB: 51% ownership by women.

Federal opportunities live on SAM.gov. State and local opportunities live on state procurement sites and city portals. ContractShield imports a daily feed from SAM.gov, grants.gov, Cook County IL, Boston Buying Plan, and similar sources into the Work Order Marketplace. Filter by NAICS code, location, dollar range, and set-aside type.

A compliant government bid includes the response to the solicitation, the price proposal, the bonding letter or bond, the prevailing wage compliance plan, the Davis-Bacon certification if federal, the past performance documentation, and any specific forms named in the solicitation. Federal contracts over $150,000 typically require a performance bond and a payment bond at 100% of contract value.

Each solicitation names a submission portal. Submit before the deadline with every required attachment. Late bids are rejected. Most awards announce within 30 to 90 days of bid close. The bid protest window is short, often 5 to 10 calendar days.
