How to get government construction contracts
Pick your NAICS codes and confirm you are small, register in SAM.gov for federal work and with your state and local agencies, line up bonding, then find solicitations, start with jobs sized to your capacity (often as a subcontractor), and build a record of clean performance.
To get government construction contracts, first set up the basics: choose the NAICS codes that describe your work, confirm you meet the small business size standard for them, register in SAM.gov (required to bid federal work as a prime), and register with the state, county, and city agencies you want to work for. Then secure bonding, because most public construction requires bid, performance, and payment bonds. After that, it is a numbers game: find solicitations, bid the ones sized to your capacity, team as a subcontractor to learn the paperwork, and use small business set-asides where you qualify.
Government work is open to any qualified contractor, pays on published rules, and does not depend on knowing the owner. It also brings more paperwork, wage rules, and price competition than most private work. Companies that win steadily treat compliance as a core skill, not an afterthought.
Federal, state, and local: where the work is
| Level | Typical buyers | Main registration | Rules that apply |
|---|---|---|---|
| Federal | Army Corps of Engineers, Navy, VA, GSA, National Park Service | SAM.gov | Federal Acquisition Regulation, Davis-Bacon, Miller Act |
| State | State DOT, universities, facilities agencies | State vendor portal, often DOT prequalification | State procurement code, state prevailing wage where it applies |
| Local | Cities, counties, school districts, water and transit authorities | Each agency's vendor list or bid portal | Local purchasing rules and state public works laws |
Many contractors start local, where jobs are smaller and the agency is nearby, then move to state and federal work. See state and local public works bidding basics for the non-federal side.
Seven steps to winning government construction work
1. Choose NAICS codes and check your size
NAICS codes classify your work, and each has a small business size standard. In the U.S. Small Business Administration's table of size standards (effective March 17, 2023, the version posted at the time of writing), most building and heavy civil codes carry a $45 million average annual receipts limit, and most specialty trade codes, such as roofing, electrical, and plumbing and HVAC, carry $19 million. Receipts are generally averaged over the latest five complete fiscal years, and affiliates count. Check the current table before you rely on these numbers.
2. Register in SAM.gov
Any business that wants to bid federal contracts as a prime needs an active SAM.gov registration, which assigns a Unique Entity ID and must be renewed every 365 days. Registration itself is free. Full steps are in how to register in SAM.gov as a contractor.
3. Register with state and local agencies
Each state and many cities run their own vendor systems. State transportation departments often require prequalification before you can bid at all. Keep your contractor license current in every state where you plan to bid.
4. Line up bonding
On federal work, the Miller Act requires performance and payment bonds on construction contracts over $150,000, and FAR 28.102-1 calls for alternative payment protection on contracts over $35,000 up to $150,000. State "Little Miller Acts" set their own thresholds. If a surety will not write you alone, the U.S. Small Business Administration's surety bond guarantee program backs bonds for small businesses on contracts up to $9 million for non-federal work and $14 million for federal work, with a guarantee fee of 0.6 percent of the contract price on performance and payment bonds and no fee on bid bonds. Read how bonding capacity is calculated for contractors before you talk to a surety.
5. Find solicitations
Federal agencies must publicize proposed contract actions expected to exceed $25,000 on the government's point of entry (SAM.gov), under FAR 5.101. Set saved searches by NAICS code and place of performance. For state and local work, sign up for each agency's bid notices. See how to find federal construction bids.
6. Use set-asides and certifications
The federal government aims to award at least 23 percent of contracting dollars to small businesses, and many construction jobs are set aside for small, 8(a), HUBZone, service-disabled veteran-owned, or women-owned firms. Read small business set-asides for construction to see which ones you may qualify for.
7. Start as a subcontractor, then move up
Working under a prime on a federal job teaches you certified payroll, submittals, and federal inspections with less risk. It also gives you past performance to cite in your first prime proposal. See how to subcontract on federal construction projects.
Worked example: a concrete contractor's first year
Say a concrete contractor doing $6 million a year in private work wants public jobs. Under NAICS 238110 (poured concrete foundation and structure), the size standard in the 2023 table is $19 million, so the company is small. Here is how a realistic first year could look in this example:
- Months 1 to 2: registers in SAM.gov, the state vendor portal, and two city portals. Talks to its surety and confirms a single-job bond limit of about $1.5 million.
- Months 2 to 6: bids eight local sidewalk and site concrete jobs between $150,000 and $600,000. Wins two.
- Months 4 to 9: subcontracts on a federal clinic project for a prime GC, handling weekly certified payroll for the first time.
- Months 9 to 12: bids a small business set-aside on SAM.gov for a $900,000 site package, using the clinic work and the city jobs as past performance.
The lesson in the example is pacing. Bonding, paperwork, and past performance grow together, and jumping straight to a large federal prime contract usually fails on one of the three.
What agencies check before they award
Price wins sealed bids, but only among bidders who clear two tests. The first is responsiveness: did the bid follow the solicitation exactly, on the agency's form, with every addendum acknowledged and the bid security attached? The second is responsibility: can this company actually do the job? Agencies look at financial capacity, bonding, licensing, safety record, and past performance. On negotiated federal procurements, past performance and technical approach can count as much as price.
That means your first wins depend on paperwork and a believable track record. Keep a running list of finished jobs with owner contacts, contract values, and photos. A responsible bidder with clean documentation beats a slightly cheaper one that cannot prove it can deliver.
Mistakes to avoid
- Paying a third party to register in SAM.gov when registration is free.
- Letting SAM.gov expire mid-bid. Set a reminder well before the 365-day renewal.
- Bidding jobs bigger than your bond capacity.
- Underpricing prevailing wage labor. See how to price prevailing wage jobs.
- Missing an addendum acknowledgment, which can make a low bid nonresponsive.
- Treating compliance as office work that can wait. Certified payroll and submittals that run late hold up payment.

Frequently asked questions
Can a small contractor really win government construction contracts?
Yes. Many federal construction contracts are set aside for small businesses, and local agencies award plenty of small jobs. Start with jobs inside your bonding capacity and build past performance.
Do I need SAM.gov for state or city contracts?
Usually not for the contract itself, since states and cities run their own vendor systems. Some locally run projects that use federal funds may ask for a Unique Entity ID, so read each solicitation.
How much does it cost to register for government contracts?
SAM.gov registration is free. Your real costs are bonding, the time spent preparing bids, and compliance work such as certified payroll.
Do I need to be bonded for government construction work?
Usually. Federal construction contracts over $150,000 require performance and payment bonds under the Miller Act, and most state and local public works have similar bond laws with their own thresholds.
How long does it take to win a first government contract?
It varies with your trade, location, and how many bids you submit. Registrations and bonding take weeks, and most companies bid several jobs before winning one, so plan on months, not days.
