What is a set-aside contract in construction?

A set-aside contract is a government contract that only a defined group of businesses may compete for, most often small businesses or firms in an SBA socioeconomic program, instead of being open to everyone.

A contractor and plan reviewer discuss drawings and permit paperwork across an office desk.

A set-aside contract limits who can bid. FAR 19.501 defines a set-aside as limiting an acquisition exclusively for participation by small business concerns. If a federal construction job is advertised as a set-aside, a large contractor cannot be the prime, no matter how good its price. Set-asides are the main tool the federal government uses to steer work to small firms, and many states and cities run their own versions.

Types of federal set-asides

FAR 19.203 names four socioeconomic programs alongside the general small business set-aside:

  • Small business set-aside: open to any firm that is small under the size standard for the job's NAICS code. See small business set-aside.
  • 8(a): for firms in the U.S. Small Business Administration's 8(a) Business Development program, which can include sole-source awards.
  • HUBZone: for firms certified in the Historically Underutilized Business Zone program.
  • SDVOSB: for service-disabled veteran-owned small businesses.
  • WOSB: for women-owned small businesses under the U.S. Small Business Administration's program.

At or below the simplified acquisition threshold there is no order of precedence among those four programs. Above it, FAR 19.203(c) says contracting officers shall first consider the socioeconomic programs before a general small business set-aside. A requirement accepted into the 8(a) program stays there unless SBA agrees to release it.

State and local set-asides

Outside federal work, set-aside rules come from state law and city ordinances. Some states reserve certain contracts for certified small or minority-owned firms. Others use participation goals instead, such as a disadvantaged business enterprise goal on a highway job, where anyone can bid but the prime must subcontract a share to certified firms. A goal is not a set-aside, though both show up in the same bid packages.

A worked example

A small electrical contractor with a HUBZone certification watches SAM.gov for work at a nearby Army installation. A lighting retrofit for a set of warehouses is posted as a HUBZone set-aside. Only eight firms can bid instead of thirty. The contractor wins at a price that is competitive but not a race to the bottom.

Then the rules kick in. The contract includes the limitations on subcontracting clause, so the firm cannot hand most of the work to non-certified subs. It must stay small under the size standard when it certifies for the bid, keep its certification current, and comply with Davis-Bacon wage rules on the construction work.

Common mistakes

  1. Bidding a set-aside without checking size under the solicitation's specific NAICS code.
  2. Planning to pass most of the work to a large sub. That breaks the limitations on subcontracting and can bring serious penalties.
  3. Letting a certification lapse or SAM registration expire between bid and award.
  4. Treating a DBE goal as a set-aside, or the other way around.

Frequently asked questions

Who can bid on a set-aside contract?

Only businesses that meet the set-aside's eligibility rules, such as being small under the contract's NAICS size standard or holding the required U.S. Small Business Administration certification (8(a), HUBZone, SDVOSB, or WOSB).

Are set-aside contracts only federal?

No. Many states and local governments run their own set-aside or preference programs. Their rules come from state law and local ordinances, not the FAR.

Can a large company work on a set-aside contract?

Usually as a subcontractor only, and within the limits of the limitations on subcontracting clause. Some mentor-protege joint ventures can also qualify under SBA rules.

What is the difference between a set-aside and a DBE goal?

A set-aside restricts who may bid as prime. A DBE goal lets anyone bid but requires the prime to use certified disadvantaged firms for a share of the work or show good faith efforts.
