Construction Government Contracts: Bonding, Davis-Bacon, and How to Win

Federal construction is not a niche — it is one of the largest and most durable segments of government spending. The federal government is the single largest owner of real property in the United States, managing hundreds of millions of square feet of building space, thousands of miles of infrastructure, and military installations that function as small cities. All of it requires construction, renovation, and maintenance on an ongoing basis.

Commercial construction work for federal agencies accounted for approximately $14.7 billion in federal spending based on recent contract data, and that figure covers only the direct construction contracts — not facility operations, design services, or construction management layered on top. DoD alone runs a dedicated Military Construction (MILCON) program, typically funding several billion dollars in new construction projects annually across Army, Navy, Air Force, and Marine Corps installations worldwide.

Small businesses capture a significant share of this market. Federal law requires at least 23% of all prime contract dollars to go to small businesses, and construction is one of the categories where agencies have historically met or exceeded that target. The small business set-aside requirement under FAR 19.502-2 applies whenever the Rule of Two is satisfied — and for local construction work, two qualified small businesses are almost always available to compete.

Unlike many professional services categories, construction work is inherently local. A contractor building a VA clinic in Raleigh is not competing against a firm based in Los Angeles. Your competition comes from your region — contractors who know the local labor market, material suppliers, and permit environment. That locality advantage is real and favors established regional businesses over national firms that do not have a local workforce and subcontractor network already in place.

The best place to track live construction solicitations is SAM.gov. Filter by NAICS 236, 237, or 238, set your geography, and subscribe to alerts. For tips on getting the most out of SAM.gov's search filters, see our guide on SAM.gov search strategies.

Construction businesses fall into three major NAICS subsectors. The code on a solicitation determines your size standard eligibility — whether you qualify as a small business and which set-aside programs you can access. Register all codes that apply to your work on SAM.gov.

For most small construction companies, the most accessible entry point is specialty trade work under NAICS 238. The size standards are lower (meaning more competitors qualify as small), competition at the subcontract level is less formal, and you can build federal past performance without taking on the full prime contractor risk of a large building project.

SBA increased most size standards by 13.65% in 2024, so if you were previously just over the limit for a particular code, recheck your eligibility now. Size standards are measured against your average annual receipts over the preceding five fiscal years — a single high-revenue year does not automatically disqualify you.

One critical performance requirement specific to construction: under FAR 52.219-14 (Limitations on Subcontracting), general construction contractors must perform at least 15% of the contract cost with their own employees, excluding materials. Specialty trade contractors face a higher bar — at least 25% of the contract cost must be performed by their own employees. These rules prevent shell companies from winning set-aside contracts and passing all the work to non-small businesses.

The Miller Act (40 U.S.C. Chapter 31, Subchapter III) is the law that governs bonding on federal construction contracts. It creates a three-tier system based on contract value, and understanding it before you bid is not optional — bonding capacity must be in place before you receive an award, not after.

Bonding is one of the biggest barriers for small construction firms entering the federal market. Surety companies evaluate your bonding capacity based on financial statements, credit, work-in-hand, and completed project history. A company with limited financial reserves may find it difficult to obtain bonds on large contracts regardless of technical qualifications.

Budget bond premiums into every bid. Performance and payment bond premiums typically run 0.5%–3% of the contract value depending on project size, your company's financial strength, and your surety relationship. On a $500,000 contract, that is $2,500–$15,000 — a cost that cannot be absorbed into labor or materials without shrinking your margin. Many first-time federal construction bidders forget to include bonding in their price and then face a surprise hit to profitability.

One additional note: contracting officers will review your bonding before issuing a Notice to Proceed (NTP). If you cannot produce the required bond within the period specified in the contract (typically 10–15 business days after award), the government can rescind the award and offer it to the next bidder. Establish your surety relationship and pre-qualify for bonding capacity before you submit your first bid over $150,000.

The Davis-Bacon Act has applied to federal construction since 1931. If your contract exceeds $2,000 and involves construction, alteration, or repair of federal buildings or works, Davis-Bacon applies. There is almost no federal construction work below that threshold in practice — meaning Davis-Bacon applies to essentially every federal construction job you will encounter.

The law requires contractors and subcontractors to pay all laborers and mechanics no less than the locally prevailing wage for their specific trade classification in the county where work is performed. The Department of Labor publishes wage determinations for each county and trade — and these numbers vary dramatically by location. An electrician's prevailing wage in Manhattan and in rural Mississippi are nowhere close to each other. Check the specific wage determination for every county where your work takes place before you price a single hour.

The Department of Labor finalized the first major overhaul of Davis-Bacon regulations in nearly 40 years in 2023, with the updated rules taking full effect in 2024. Key changes: the definition of "prevailing wage" was broadened, the WH-347 certified payroll form was updated in January 2025 with enhanced fringe benefit reporting fields, and civil penalties for violations increased to $13,508 per violation. The old form is accepted through September 30, 2026, after which only the updated WH-347 will be accepted.

Davis-Bacon also flows down to every subcontractor on your project. As prime contractor, you are legally responsible for ensuring your subs are paying prevailing wages and submitting certified payrolls. Subs who cut corners on wages create liability for you — the DOL can hold the prime responsible for sub non-compliance, and violations can result in contract debarment in addition to the per-violation penalty.

Track certified payroll submissions systematically. A missed week of certified payroll — even for a crew of two workers — is a contract violation. Build a calendar reminder system into your project management before work starts, and collect certified payrolls from every sub weekly, not quarterly.

Set-aside programs are your biggest competitive lever as a small construction company. When a solicitation is restricted to certified businesses, you are not competing against large national contractors — you are competing against a small pool of similarly sized regional firms. In construction, set-asides appear at every value level, from minor repair work under $150,000 to multi-million-dollar renovation projects.

One important construction-specific rule: for contracts over $1.5 million, prime contractors must submit a small business subcontracting plan committing to percentages of subcontract dollars flowing to small businesses, SDVOSBs, WOSBs, HUBZone firms, and 8(a) businesses. If you are a large construction prime, this creates a mandatory sourcing requirement. If you are a small construction company, these plans are your pathway into large prime contracts as a subcontractor — primes actively seek qualified small subs to meet their contractual commitments.

Military Construction (MILCON) is a distinct federal budget category — Congress appropriates MILCON funding separately from operation and maintenance budgets, and it flows through specialized acquisition commands within the Army, Navy, Air Force, and Marine Corps. For construction companies, this means MILCON projects have their own procurement offices, their own contracting officers, and their own relationships to cultivate.

The two primary MILCON acquisition commands are the U.S. Army Corps of Engineers (USACE) and Naval Facilities Engineering Systems Command (NAVFAC). USACE handles construction for Army installations and also executes a large Civil Works program (flood control, navigation, water resources). NAVFAC covers Navy and Marine Corps installations. The Air Force Civil Engineer Center manages Air Force and Space Force facilities. Each has district offices that procure regionally — finding and engaging the district office nearest your target installation is essential.

Multiple Award Construction Contracts (MACCs) and Indefinite Delivery/Indefinite Quantity (IDIQ) vehicles are increasingly common in MILCON. Rather than competing for a single project, you compete once for a spot on a multi-year vehicle — then receive task order competitions from agencies on the vehicle. Getting on one of these vehicles dramatically increases your MILCON opportunity pipeline without requiring you to bid from scratch on every project.

NAVFAC's MACC vehicles and USACE's Indefinite Delivery contracts frequently include small business set-aside pools or small business task order set-asides within a larger unrestricted vehicle. Being on a USACE or NAVFAC IDIQ is worth the effort of winning the base vehicle even if the first task orders are modest — the volume of opportunities that flow from an active IDIQ typically far exceeds what you can find through open solicitations alone.

For a full explanation of IDIQ mechanics and how to pursue them, see our guide to IDIQ contracts. And if you are looking at DoD opportunities more broadly, our DoD small business guide covers the full DoD acquisition landscape.

Federal construction solicitations use one of two evaluation methods. Which one applies has a major effect on how you should write your proposal — and whether your price alone can win or whether quality factors determine the outcome.

On Best Value construction contracts, agencies typically evaluate these factors:

Your Experience Modification Rate (EMR) is a critical differentiator on Best Value construction bids. The EMR measures your safety performance relative to the industry average — a score below 1.0 means you have fewer injuries than average; above 1.0 means more. Many federal construction solicitations set a maximum EMR threshold (commonly 1.0 or 1.2) as a pass/fail requirement. Companies above the threshold are eliminated before price or technical factors are even reviewed.

Track your EMR and manage your safety program proactively. One serious OSHA recordable incident can push you over threshold and disqualify you from solicitations for up to three years (the EMR is based on a rolling three-year window). Document your safety program, conduct regular toolbox talks, maintain your OSHA 300 log meticulously, and report incidents correctly. A good safety record is worth more in federal construction bidding than a marginal price reduction.

Nine concrete steps. Tackle them in order and you can be submitting competitive federal construction bids within six to eight months.

These patterns show up in post-award debriefs and construction contractor failures, repeatedly, across every agency and every region.
