Construction Government Contracts in Illinois
Government construction contracts cover new builds, renovations, and repairs for federal buildings, military facilities, schools, and infrastructure. Under NAICS 236220 (Commercial and Institutional Building Construction), they carry construction-specific rules: Davis-Bacon prevailing wages, bid/performance/payment bonds, and often a sealed-bid (IFB) process where the lowest responsive, responsible bidder wins. Bonding capacity is the gate that determines what size projects you can pursue.

Frequently asked questions
How much does the federal government spend on construction in Illinois?
Since Oct 2024, agencies obligated $321.3M across 442 construction contracts performed in Illinois (NAICS 236220), an average of $727K per award. The Department of Veterans Affairs is the largest buyer.
Where are construction bids posted in Illinois?
Federal opportunities performed in Illinois are posted on SAM.gov (filter by place of performance). State-level work is posted on BidBuy, and counties, cities, and school districts run their own portals — register with the largest ones in your service area.
Do I need to register with the state of Illinois to bid?
For Illinois state agency contracts, yes — register as a vendor on BidBuy. Federal contracts performed in Illinois only require SAM.gov registration, though state small-business certifications can still help with subcontracting.
How much bonding do I need to bid federal construction?
The Miller Act requires performance and payment bonds on federal construction over $150,000. Your surety's single-project limit effectively caps the size you can bid. The SBA Surety Bond Guarantee program helps small contractors get bonded.
What is Davis-Bacon and how does it affect my bid?
Davis-Bacon requires paying locally prevailing wages and fringes (published in the solicitation's wage determination) on federal construction over $2,000, with certified weekly payrolls. Underpricing labor against the determination is a common fatal bid error.
