Finding primes to sub for on federal jobs
Most specialty shops enter federal work as subcontractors first — the prime carries the bonds and the past-performance burden while you build a federal track record. The primes winning work near you are a matter of public record; here's how to find them and get on their bid lists.
Why subbing first is the standard on-ramp
Winning prime work takes past performance, bonding capacity, and administrative muscle that a shop new to federal contracting hasn't built yet. Subbing sidesteps all three: the prime holds the Miller Act bonds (whose payment bond protects you — see bonding explained), and every completed sub scope becomes the past-performance story you'll cite when you do bid prime.
The award trail is public
Every federal contract award is public record. USAspending.gov lets you search awards by NAICS code, place of performance, and agency — filter to construction codes in your state and you have a list of the GCs winning work within your radius, with contract values and award dates. The big building awards cluster under NAICS 236220; that page is effectively a directory of who your future primes are competing under.
Recently awarded is exactly the right time to call: the prime is buying out the job, and a sub who shows up with the right scope before buyout closes is solving their problem, not asking a favor.
Get visible where primes look for subs
Primes assemble bid lists from a few standard places:
- Sources-sought and presolicitation responses — large primes monitor these too, and agencies sometimes share interested-vendor lists; being visible early gets you calls during pricing.
- SBA SubNet — where primes with subcontracting plans post opportunities for small-business subs.
- Agency small-business offices and OSDBU events — their job is literally connecting firms like yours to primes that carry small-business subcontracting goals.
- Industry days and pre-bid site visits — the sign-in sheet at a site visit is a list of every prime pricing the job; work it.
- Large primes' own supplier-registration portals — fifteen minutes each for the GCs that dominate your region's federal work.
The pitch that gets returned
Estimators buying out a job respond to specificity and speed: name the project, the scope you'd carry (in spec-division terms), and the facts they'd otherwise have to ask for — bonding, certifications and size status (a prime with small-business subcontracting goals needs your set-aside status on file), insurance, and crew availability. Attach your capability statement and quote the bid date back to them.
Then be systematic about which jobs trigger the outreach. Watching the solicitations near you — not just the awards — tells you which primes are about to need your trade weeks earlier; the daily digest is built to be that trigger.
Put this on autopilot.
