How federal agencies buy construction

Federal construction comes as sealed bids or negotiated RFPs on the SF 1442 form, usually with a site visit and a magnitude range for the price. Contracts over $2,000 pay Davis-Bacon prevailing wages, and larger ones need performance and payment bonds under the Miller Act. Agencies weigh past performance on similar projects and also use design-build. Common NAICS codes: 236220 for buildings, 237310 for roads and bridges, 237990, and specialty trades such as 238220 and 238210.

Contracting officers set a purchase aside for small businesses when they expect offers from at least two capable small firms at fair prices (the rule of two). Whether a firm counts as small depends on the SBA size standard for the notice's NAICS code, in annual receipts or employees, and offerors need an active SAM.gov registration with a Unique Entity ID.
