§3309 Design-build selection procedures

Title 41 › Subtitle Subtitle I— - Federal Procurement Policy › Chapter CHAPTER 33— - PLANNING AND SOLICITATION › § 3309

Last updated Apr 6, 2026|Official source

Summary

Federal agencies must use a two-step selection process for hiring teams to both design and build a public building or facility unless they use the usual design-bid-build way or another allowed method. A contracting officer must decide this process is right when they expect 3 or more bids, when design work is needed before a bidder can give a price, when bidders will spend a lot to prepare offers, and after they check things like how well the project is defined, the delivery timetable, potential contractors’ experience, whether the project fits the two-step method, the agency’s ability to run the two-step process, and any other agency rules. In the first step the agency provides a clear scope of work (which can include preliminary design, budget limits, and schedule) and asks for proposals that show a team’s technical approach and qualifications but not detailed designs or prices. The agency rates teams on experience, technical skill, ability to perform, past work, and other stated factors (but not price). The agency then names the top teams (the solicitation says how many; normally no more than 5 unless more is justified) and asks them for full technical designs and cost proposals in step two. Technical and price parts are scored separately, and the contract is awarded under the government’s award rules. The Federal Acquisition Regulation must give guidance to agencies on when to use this method, how to pick contractors, and a consistent government-wide approach.

Public Contracts — Source: USLM XML via OLRC

(a)Unless the traditional acquisition approach of design-bid-build established under sections 1101 to 1104 of title 40 or another acquisition procedure authorized by law is used, the head of an executive agency shall use the two-phase selection procedures authorized in this section for entering into a contract for the design and construction of a public building, facility, or work when a determination is made under subsection (b) that the procedures are appropriate for use.
(b)A contracting officer shall make a determination whether two-phase selection procedures are appropriate for use for entering into a contract for the design and construction of a public building, facility, or work when—
(1)the contracting officer anticipates that 3 or more offers will be received for the contract;
(2)design work must be performed before an offeror can develop a price or cost proposal for the contract;
(3)the offeror will incur a substantial amount of expense in preparing the offer; and
(4)the contracting officer has considered information such as the following:
(A)The extent to which the project requirements have been adequately defined.
(B)The time constraints for delivery of the project.
(C)The capability and experience of potential contractors.
(D)The suitability of the project for use of the two-phase selection procedures.
(E)The capability of the agency to manage the two-phase selection process.
(F)Other criteria established by the agency.
(c)Two-phase selection procedures consist of the following:
(1)The agency develops, either in-house or by contract, a scope of work statement for inclusion in the solicitation that defines the project and provides prospective offerors with sufficient information regarding the Federal Government’s requirements (which may include criteria and preliminary design, budget parameters, and schedule or delivery requirements) to enable the offerors to submit proposals that meet the Federal Government’s needs. If the agency contracts for development of the scope of work statement, the agency shall contract for architectural and engineering services as defined by and in accordance with sections 1101 to 1104 of title 40.
(2)The contracting officer solicits phase-one proposals that—
(A)include information on the offeror’s—
(i)technical approach; and
(ii)technical qualifications; and
(B)do not include—
(i)detailed design information; or
(ii)cost or price information.
(3)The evaluation factors to be used in evaluating phase-one proposals are stated in the solicitation and include specialized experience and technical competence, capability to perform, past performance of the offeror’s team (including the architect-engineer and construction members of the team), and other appropriate factors, except that cost-related or price-related evaluation factors are not permitted. Each solicitation establishes the relative importance assigned to the evaluation factors and subfactors that must be considered in the evaluation of phase-one proposals. The agency evaluates phase-one proposals on the basis of the phase-one evaluation factors set forth in the solicitation.
(4)(A)The contracting officer selects as the most highly qualified the number of offerors specified in the solicitation to provide the property or services under the contract and requests the selected offerors to submit phase-two competitive proposals that include technical proposals and cost or price information. Each solicitation establishes with respect to phase two—
(i)the technical submission for the proposal, including design concepts or proposed solutions to requirements addressed within the scope of work, or both; and
(ii)the evaluation factors and subfactors, including cost or price, that must be considered in the evaluations of proposals in accordance with subsections (b) to (d) of section 3306 of this title.
(B)The contracting officer separately evaluates the submissions described in clauses (i) and (ii) of subparagraph (A).
(5)The agency awards the contract in accordance with chapter 37 of this title.
(d)A solicitation issued pursuant to the procedures described in subsection (c) shall state the maximum number of offerors that are to be selected to submit competitive proposals pursuant to subsection (c)(4). The maximum number specified in the solicitation shall not exceed 5 unless the agency determines with respect to an individual solicitation that a specified number greater than 5 is in the Federal Government’s interest and is consistent with the purposes and objectives of the two-phase selection process.
(e)The Federal Acquisition Regulation shall include guidance—
(1)regarding the factors that may be considered in determining whether the two-phase contracting procedures authorized by subsection (a) are appropriate for use in individual contracting situations;
(2)regarding the factors that may be used in selecting contractors; and
(3)providing for a uniform approach to be used Government-wide.
