Government Construction Contracts & Bids
Construction and infrastructure is one of the largest and most geographically distributed categories of government contracting. From federal facility renovations to municipal road resurfacing, public agencies at every level buy construction services through formal solicitations. This guide covers the NAICS codes that matter, set-aside opportunities, the bonding and prevailing-wage rules unique to construction, and how to surface matching opportunities across federal, state, and local portals before bid deadlines pass.

Open the full dossier at normal sizeWhy Construction Is Different From Other Government Contracting
Most government contracting advice assumes you sell products or professional services to federal agencies through SAM.gov. Construction breaks that mold in two important ways. First, the overwhelming majority of public construction spending happens at the state, county, and municipal level — think school districts, water authorities, departments of transportation, parks departments, and city public works offices. Second, construction contracts carry their own legal framework: performance and payment bonds, prevailing-wage requirements, licensing, and design-bid-build versus design-build delivery methods.
That distributed landscape is both the opportunity and the challenge. A general contractor in a single metro area might have a dozen relevant buyers — the city, the county, two or three school districts, a transit authority, a housing authority, and the federal agencies with a regional footprint nearby. Each of those buyers posts solicitations on a different portal, on a different schedule, in a different format. The contractors who win consistently are usually the ones who simply see more relevant bids, earlier.
On the federal side, construction is still a meaningful market. Agencies like the U.S. Army Corps of Engineers, the General Services Administration, the Department of Veterans Affairs, the National Park Service, and military installations award construction work through SAM.gov every day. Many of these are set aside for small businesses, which makes federal construction a realistic entry point even for smaller firms.
Construction NAICS Codes That Matter
Your NAICS code determines which solicitations you match against, your small-business size standard, and how agencies classify your firm. Construction sits primarily in NAICS sector 23, where size standards are measured by average annual revenue rather than employee count. Picking the right primary and secondary codes is one of the highest-leverage decisions you can make. Use our free NAICS Finder to confirm the best codes for your business.
- •236220 — Commercial & Institutional Building Construction. The catch-all for general contractors building or renovating schools, offices, hospitals, warehouses, and government facilities. This is the most common primary code for full-service GCs pursuing public building work.
- •236210 — Industrial Building Construction. Plants, processing facilities, and other industrial structures often procured by utilities, ports, and federal installations.
- •237310 — Highway, Street & Bridge Construction. Roadwork, paving, resurfacing, bridge repair, and related heavy civil work. State departments of transportation are the dominant buyers here, with steady federal-aid highway funding flowing through them.
- •237110 / 237120 / 237130 — Utility System Construction. Water and sewer lines (237110), oil and gas pipelines (237120), and power and communication lines (237130). Municipal water authorities and utilities procure heavily in these codes.
- •238xxx — Specialty Trade Contractors. The 238 subsector covers the specialty trades: electrical (238210), plumbing and HVAC (238220), masonry (238140), painting (238320), roofing (238160), drywall (238310), and many more. Subcontractors and trade specialists pursue public work directly in these codes, and prime contractors use them to find and vet teaming partners.
- •237990 — Other Heavy & Civil Engineering Construction. Dams, marine construction, dredging, land subdivision site work, and flood-control projects. The Army Corps of Engineers and FEMA-funded recovery work frequently fall here.
Set-Asides in Construction Contracting
Federal construction is one of the most set-aside-friendly markets for small businesses, because agencies have strong small-business goals and construction requirements break naturally into manageable project sizes. If you hold a small-business or socioeconomic certification, a large share of federal construction work may be reserved exclusively for firms like yours.
- •Small Business Set-Asides. Construction requirements above the micro-purchase threshold and within small-business size standards are routinely set aside for small businesses under the FAR "rule of two." See our small business contracts guide for the fundamentals.
- •8(a) Business Development. Construction is a major category of 8(a) sole-source and competitive awards. Read our 8(a) set-aside guide to understand eligibility and the application process.
- •HUBZone. Because construction is performed on-site, HUBZone certification can be especially valuable for firms located in and employing residents of historically underutilized business zones near where work is needed.
- •SDVOSB and WOSB. Service-disabled veteran-owned and women-owned small businesses have dedicated set-aside authority in construction trades. See our SDVOSB guide and WOSB guide.
- •State and local DBE / MBE / WBE programs. Outside the federal system, departments of transportation and large municipalities run Disadvantaged, Minority, and Women Business Enterprise programs — often with goals attached to federally funded highway and transit projects. These are separate certifications from federal set-asides but open similar doors.

Bonding, Prevailing Wage & Compliance Rules Unique to Construction
Construction government contracts carry compliance obligations that do not exist in most product or services contracts. Understanding them before you bid is essential, because they directly affect your cost structure and whether you can perform the work at all.
Performance and payment bonds
For federal construction contracts above a statutory threshold, the Miller Act requires a performance bond and a payment bond. Most states have "Little Miller Acts" imposing parallel requirements on public construction. Bonding capacity from a surety is effectively a credit line, so newer contractors should build a relationship with a surety agent early and target project sizes within their bonding limit. Some agencies offer bid bonds on smaller projects in lieu of full performance bonds.
Prevailing wage (Davis-Bacon and state equivalents)
Federal construction contracts above the Davis-Bacon threshold require you to pay laborers and mechanics the locally prevailing wages and fringe benefits determined by the Department of Labor. Many states layer their own prevailing-wage laws on top for state-funded work. These wage determinations must be built into your bid pricing, and certified payroll reporting is required during performance. Underestimating prevailing-wage labor cost is one of the most common reasons construction bids lose money.
Licensing and registration
Most states require a contractor license to perform public work, and the license class often dictates the maximum project value you can bid. Beyond licensing, federal bidders need an active SAM.gov registration and Unique Entity ID, while state and local portals typically have their own vendor registration. Keep these current — an expired registration can disqualify an otherwise winning bid.
Delivery methods and other clauses
Public construction is most often awarded design-bid-build (low responsive, responsible bidder), but design-build, construction manager at risk, and job order contracting (JOC / IDIQ) are common too. Watch for Buy American requirements on materials, EEO and affirmative-action clauses, and liquidated-damages provisions tied to the schedule. Reading these terms before bidding protects your margin.
Where Construction Opportunities Live
The single biggest practical problem in construction government contracting is fragmentation. Unlike a federal-only seller who can live on SAM.gov, a construction firm has to watch many sources at once:
- •SAM.gov (federal). The system of record for federal construction solicitations, including Army Corps, GSA, VA, and military installation work, plus Sources Sought notices that signal upcoming projects.
- •State procurement portals. Every state runs at least one central bid portal, and most departments of transportation run a separate one for road and bridge lettings.
- •County and municipal sites. Cities, counties, school districts, water and sewer authorities, housing authorities, and transit agencies each post their own invitations to bid — frequently on small, inconsistent portals.
- •Disaster and recovery funding. FEMA-related rebuilding work flows through state and local channels after declared disasters, creating bursts of construction demand.
Checking dozens of these portals by hand every day is exactly the kind of work that gets skipped when you are busy running active projects — and a missed posting is a missed bid. This fragmentation is the problem GovSentry was built to solve.
How GovSentry Surfaces Matched Construction RFPs
GovSentry monitors SAM.gov alongside 100+ procurement portals spanning all 50 states plus DC — the state and local coverage that is the core of what we do. Instead of you visiting each site, our AI discovery engine reads new postings continuously and matches them to your profile by NAICS code, work location, and set-aside eligibility. For construction firms, that means a roofing subcontractor in the 238 codes and a heavy civil GC in 237310 each see a very different, highly relevant stream of opportunities.
You choose how you want to be notified: a once-a-day digest of everything that matched, plus real-time alerts the moment a high-value opportunity appears so you never lose lead time on a competitor. From there, you can move bids through a simple Kanban pipeline, track which ones you won or lost to learn what actually closes, and run market research on incumbents and prior awards before you price your bid.
GovSentry has analyzed 40,000+ federal awards and tracks 137,000+ federal opportunities from SAM.gov, drawing on real data sources including SAM.gov, USAspending, Grants.gov, the Federal Register, FEMA, and the SBA — combined with AI web-search across the 100+ state and local portals where most construction work is actually posted. If your SAM.gov registration is approaching expiration, GovSentry reminds you so a lapsed registration never knocks you out of a bid.
Frequently Asked Questions
Do I need to be on SAM.gov to win construction contracts?
You need an active SAM.gov registration to bid on and receive federal construction contracts. For state, county, and municipal construction work, you register on those agencies' own vendor portals instead — SAM.gov is not required for purely state and local bidding, though many local projects funded with federal dollars still carry federal clauses.
What NAICS code should a general contractor use?
Most general contractors pursuing public building work use 236220 (Commercial & Institutional Building Construction) as a primary code, then add secondary codes for the specialty trades and civil work they self-perform. The right mix depends on your size standard and the projects you target — our NAICS Finder can help you decide.
How much bonding capacity do I need to start?
There is no universal number — your surety sets a single-project and aggregate bonding limit based on your financials, experience, and working capital. A practical strategy is to target public projects that sit comfortably within your current bonding capacity, build a clean performance record, and grow your capacity over time. Newer firms sometimes start with smaller local projects that have lower or no bonding requirements.
Does prevailing wage apply to every public construction job?
Not always. Federal Davis-Bacon prevailing wages apply to federal and federally assisted construction above a dollar threshold, and many states apply their own prevailing-wage laws to state-funded work above state-specific thresholds. Always check the solicitation for the applicable wage determination and build those labor rates into your bid before you commit.
Can GovSentry find local construction bids, not just federal ones?
Yes — that is the point. GovSentry's coverage spans 100+ procurement portals across all 50 states plus DC in addition to SAM.gov, so you see city, county, school district, and DOT construction RFPs matched to your trades and your service area, not only federal solicitations.
