Federal construction is one of the best markets a small contractor can enter. Projects are steady, payment is backed by the U.S. Treasury, and a large share of the work is set aside for small businesses. It is also one of the easiest markets to lose money in, because federal construction runs on its own rules: bonds, prevailing wages, certified payroll, subcontracting limits, and size standards that may change in 2027.

This guide is for small construction firms, general and specialty trades alike, that want to win federal projects in fiscal years 2026 and 2027. It covers where the projects come from, the dollar triggers on every federal job, how to qualify, and the changes coming over the next 12 months.

The essentials: Federal construction projects over $2,000 require Davis-Bacon prevailing wages. Over $150,000, you need Miller Act performance and payment bonds. On a small business set-aside, a general contractor may pay non-similarly-situated subcontractors no more than 85% of the contract amount, excluding materials (75% for special trades). SBA's surety bond guarantee can back bonds on federal contracts up to $14 million.

The Rules That Decide Whether You Make Money

Davis-Bacon prevailing wages (over $2,000)

Every federal construction contract over $2,000 requires you and your subcontractors to pay at least the locally prevailing wages and fringe benefits in the wage determination attached to the contract. You must submit certified payroll weekly. The $2,000 threshold is statutory and was not changed by the 2025 inflation adjustment.

Cost trap: Bid with the wage determination in the solicitation, by classification, and include fringe benefits. Underpricing labor is the most common reason small firms lose money on their first federal job.

Miller Act bonds (over $150,000)

Under the Miller Act, the prime contractor on a federal construction contract over $150,000 must furnish a performance bond and a payment bond, usually each for 100% of the contract price. Bond thresholds were excluded from the October 2025 inflation adjustment, so $150,000 still applies in 2026-2027. Smaller contracts may require alternative payment protections under FAR 28.102-1.

Many solicitations also require a bid guarantee, typically 20% of the bid price, up to $3 million. Missing or defective bid bonds make a bid nonresponsive.

Limitations on subcontracting

On a small business set-aside, the prime must keep enough of the work in-house. Under 13 CFR 125.6:

Contract typeMax paid to non-similarly-situated subsExcludes
General construction85% of the amount paidCost of materials
Special trade construction75% of the amount paidCost of materials

Subcontractors that hold the same small business status as you, called similarly situated entities, count as your own work. A HUBZone general contractor that uses HUBZone subs, or an SDVOSB that uses SDVOSB subs, has much more flexibility.

Subcontracting plans (large primes over $2 million)

Large business primes on construction contracts over $2 million (up from $1.5 million) must have small business subcontracting plans. That is your opening as a specialty trade sub: primes need to meet those goals. Get on their bidder lists before the prime contract is awarded.

Bonding: The Real Barrier, and How to Get Past It

For most small contractors, bonding capacity, not skill, is what limits project size. Sureties look at your working capital, net worth, credit, backlog, and track record.

Use the SBA Surety Bond Guarantee program

SBA guarantees bonds issued by participating sureties, which makes them more willing to bond small and growing contractors.

FeatureLimit
Non-federal contractsUp to $9 million
Federal contractsUp to $14 million, if a federal contracting officer certifies the guarantee is necessary
Guarantee rate90% for contracts of $100,000 or less, or for socially and economically disadvantaged, HUBZone, veteran-owned, and service-disabled veteran-owned businesses; 80% otherwise

Build capacity step by step

  1. Start with Z-coded repair and alteration jobs under $150,000, where Miller Act bonds are not required.
  2. Keep CPA-reviewed financial statements. Sureties want them, and they speed up bond decisions.
  3. Build a relationship with a surety bond producer who works federal construction.
  4. Grow bond size gradually with clean completions. Each successful project raises your single-job and aggregate limits.
  5. Consider an SBA mentor-protégé joint venture with a larger contractor for projects beyond your bonding.

Size Standards: The Big Change Coming in 2027

Today, most construction size standards are based on average annual receipts. On August 20, 2026, SBA proposed converting the entire construction sector to employee-based standards as part of a sweeping overhaul.

Comparison of current and proposed SBA construction size standards: 236220 commercial building from $45 million receipts to 600 employees, 237310 highway and bridge from $45 million to 700 employees, 237990 other heavy civil from $45 million to 900 employees
SBA's August 20, 2026 proposal would move construction size standards from receipts to employees. Not final.
NAICSIndustryCurrent standardProposed (Aug 2026)

237310Highway, street, and bridge$45 million receipts700 employees

Certifications That Win Federal Construction Work

2026-2027 Market Outlook

A 90-Day Plan to Win Your First Federal Construction Contract

  1. Days 1-15: Register in SAM.gov with accurate NAICS codes, get your UEI, and confirm your size status. Apply for any certification you qualify for (VetCert, HUBZone, 8(a), WOSB).
  2. Days 1-30: Meet a surety bond producer. Get prequalified and learn your single-job and aggregate limits.
  3. Days 15-45: Build a one-page construction capability statement: trades, bonding capacity, safety record (EMR), licenses, and three best projects with photos.
  4. Days 15-60: Save SAM.gov searches by NAICS, PSC Y and Z, and set-aside. Register with USACE district and NAVFAC small business offices near you.
  5. Days 30-90: Bid two or three small repair and alteration jobs under $350,000. Price labor from the wage determination. Win, perform cleanly, and use it as past performance.

How to Price a Federal Construction Bid Without Losing Money

Federal construction pricing has a few line items commercial estimators often miss. Build them into your estimate template so they are never forgotten.

Cost itemWhat to include
LaborWage rate plus fringe from the Davis-Bacon wage determination for each classification, not your normal rates. Apply it to subcontractor labor too.
BondsBid, performance, and payment bond premiums. Ask your surety producer for your rate before you bid.
Payroll administrationTime to prepare weekly certified payrolls and collect them from every subcontractor.
Site and security requirementsBase access, badging, escort time, background checks, and restricted work hours on military installations.
Submittals and quality controlMany federal projects require a dedicated quality control manager, submittal registers, and specific testing.
Safety programFederal safety requirements such as the USACE safety manual (EM 385-1-1) on Corps projects, with a written safety plan and site safety staff.
Cash flowMonthly progress payments, possible retainage, and the time it takes to get paid. Price your financing cost.

Read the whole solicitation, not just the drawings

Federal construction solicitations often run hundreds of pages. Special contract requirements, liquidated damages, phasing, and working hours sit in Sections C, H, and the specifications. Liquidated damages for late completion can wipe out the profit on a small job. Read them before you price, and ask questions during the question period if anything is unclear.

Five Reasons Small Contractors Lose Money on Their First Federal Job

  1. Pricing labor at commercial rates instead of the wage determination.
  2. Underestimating submittals and QC. Federal projects require more paperwork before and during work than most private jobs.
  3. Ignoring base access delays. Gate processing, escorts, and restricted hours slow crews down.
  4. Subcontracting too much. On a set-aside, paying non-similarly-situated subs more than the limit is a compliance problem, not just a margin problem.
  5. Running out of cash. Bonds, payroll, and materials go out before the first progress payment comes in. Line up working capital first.

Breaking In as a Subcontractor First

Many successful federal general contractors started as specialty subs on federal projects. It is a good way to learn the system with less risk.

Bottom line: In federal construction, the firms that win are the ones that understand bonds, wages, and subcontracting limits before they bid. Start small, build bonding, and get certified.
