How to Bid on Federal Construction Contracts: A Guide for Contractors

Federal construction is one of the largest markets in government contracting, and one of the most rule-heavy. Contractors who do well commercially are often surprised by how much of a federal bid has nothing to do with building: bonding, wage rules, set-aside eligibility, past performance forms, and strict proposal instructions.

We prepare federal construction proposals every month, from single-project bids to multiple-award contracts for the Navy, Army, Air Force and VA. This guide covers how the market works and what it takes to compete.

Where to find federal construction work

Federal opportunities are posted on SAM.gov. Larger contracts are usually announced ahead of time with a presolicitation notice, and above the simplified acquisition threshold, currently $350,000, offerors generally get at least 30 days to respond.

If you pursue Defense Department work, note one 2026 change: starting October 1, 2026, DoD contracting offices must use the PIEE Solicitation Module to publish most unclassified solicitations and receive offers. Get your company's PIEE accounts and roles set up before you need them.

Many agencies also post sources sought notices before a solicitation. Responding to them can influence whether a contract is set aside for small businesses. See How to Respond to a Sources Sought Notice.

How the government buys construction

There are two main methods.

Sealed bidding

With sealed bidding, bids are opened publicly and award goes to the responsible bidder whose conforming bid has the lowest price. There are no discussions. It's used when the requirement is well defined and price is the deciding factor.

Negotiated proposals

Most larger construction contracts, and nearly all multiple-award contracts, are bought through proposals. The government evaluates factors such as:

• Relevant experience and past performance
• Technical approach and management plan
• Key personnel
• Safety record, often including your experience modification rate
• Price

Awards are either best value tradeoff, where the government can pay more for a stronger offer, or lowest price technically acceptable, where the lowest price among acceptable proposals wins.

Design-build

Many agencies buy design and construction together. Larger design-build projects often use a two-phase process: qualifications first, then a shortlist submits technical and price proposals. See Two-Phase Design-Build Proposals Explained.

Multiple-award contracts

Agencies increasingly buy construction through MATOCs and MACCs, multiple-award contracts where a group of prequalified contractors compete for individual task orders. See What Is a MATOC or MACC?.

Set-asides and small business programs

Small businesses have real advantages in federal construction:

• When a contracting officer expects offers from two or more capable small businesses at fair prices, the contract is generally set aside for small business.
• The Defense Department sets aside construction under $3.5 million for small businesses unless the set-aside criteria can't be met.
• Contracts can also be set aside for 8(a), HUBZone, SDVOSB and WOSB firms. The VA gives first priority to service-disabled veteran-owned businesses.

Your size is measured against the size standard for the solicitation's NAICS code, which for general building construction is in the tens of millions in annual receipts. See WOSB vs. 8(a) vs. SDVOSB vs. HUBZone.

The requirements that surprise new bidders

• Bonding. Performance and payment bonds are required on contracts over $150,000, plus a bid guarantee on most bids.
• Davis-Bacon wages. Construction contracts over $2,000 require paying prevailing wages and submitting weekly certified payrolls.
• Limitations on subcontracting. On a small business set-aside, you can't pay more than 85% of the contract amount, excluding materials, to subcontractors that aren't similarly situated (75% for special trade contractors).
• Past performance minimums. Many solicitations require a set number of projects above a dollar value, completed within a recent window.

We cover these in Bonding, Davis-Bacon and Other Federal Construction Requirements and Past Performance for Federal Construction Proposals.

A note on the FAR overhaul

The Federal Acquisition Regulation is in the middle of a major rewrite. Most agencies now follow deviation versions of the rules that renumber familiar sections, and formal rulemaking for the construction-related parts was proposed in September 2026. Some things have changed, such as the removal of the old clause requiring primes to self-perform a set share of the work. Others haven't, like the limitations on subcontracting for set-asides. The safest rule: follow the clauses and instructions in the solicitation you're bidding.

Where to go from here

Federal construction rewards contractors who read solicitations carefully and build compliant, well-documented proposals. If you're preparing a bid, we can help you understand what the solicitation requires and put together a proposal that meets every requirement.
