Federal Registration & Set-Asides
SAM.gov registration, UEI and CAGE, representations and certifications, and the socioeconomic set-asides (SDVOSB, 8(a), HUBZone, WOSB) that put your firm in front of work it can actually win.
Overview
Get eligible to compete.
Every federal dollar starts with registration. Before your AEC firm can bid on or receive a single federal contract, it has to be active in SAM.gov, which issues your 12-character Unique Entity Identifier (the UEI that replaced the DUNS number on April 4, 2022) and triggers an automatic CAGE code from the Defense Logistics Agency. Layered on top of that registration are the SBA socioeconomic certifications that open set-aside and sole-source lanes you can't otherwise see: SDVOSB/VOSB, 8(a), HUBZone, and WOSB/EDWOSB. The rules shifted hard in 2025 and 2026, and filing on stale guidance is exactly where firms trip. This is the part of federal work that has nothing to do with engineering, and it's where a quarterback earns the engagement: get the sequence right, pick the correct lane, and hold the renewal and recertification cadence so you stay eligible instead of self-certifying into a gap.
What you need to know
The rules, stated plainly.
SAM.gov, the UEI, and the CAGE code
SAM.gov registration is free, mandatory before award, and not optional for any path. It assigns the 12-character alphanumeric UEI automatically and, for domestic entities, triggers the CAGE code from the Defense Logistics Agency during the same process. You'll need your legal business name exactly as it appears on IRS/EIN records, a physical address, your EIN/TIN, banking information for the federal payment profile, and completed Reps and Certs (the FAR/DFARS representations). The number most firms miss: registration expires after 365 days, with no auto-renewal and no grace period. A lapsed registration the week a solicitation drops means you can't be awarded. We treat the renewal date as a hard calendar event, not an afterthought. And no, you don't need a DUNS number anymore. The federal government retired it in 2022.
What 'small' actually means for an AEC firm
Whether you even see set-aside lanes turns on your primary NAICS code and the SBA size standard attached to it. For AEC firms that's usually Engineering Services (541330) at $25.5M average receipts or Architectural Services (541310) at $12.5M. Critically for DoD work, 541330 carries a separate $47M exception ceiling for military and aerospace engineering, which means a firm too large to be 'small' for civilian engineering can still be small for defense engineering, depending on how the contracting officer codes the solicitation. Size is measured by average annual receipts over your most recent five completed fiscal years, and the primary NAICS on each individual solicitation governs. One note on the horizon: in August 2025 SBA proposed raising these standards (541310 to $16.0M, 541330 to roughly $29.0M, keeping the $47M military exception). As of mid-2026 that remains a proposed rule, so the current $12.5M and $25.5M figures still apply. We track this so you certify against the rule that's actually in force.
The veteran lane: SDVOSB and VOSB through SBA VetCert
For veteran-owned engineering firms, this is the most live lane in federal AEC, and the rules just changed in a way that punishes the unprepared. SDVOSB/VOSB certification moved from the VA to the SBA's VetCert program on January 1, 2023. More importantly, self-certification is dead: the June 2024 SBA rule ended self-certification credit effective August 5, 2024, with a transition grace period that closed December 22, 2024. Firms that didn't have a certification (or a timely pending application) through VetCert by then can no longer count toward SDVOSB goals or win SDVOSB set-aside and sole-source awards. An uncertified veteran-owned firm is now invisible to set-asides it could have won a year earlier. Eligibility requires at least 51% direct, unconditional ownership and control by one or more veterans (service-disabled veterans for SDVOSB), small under your primary NAICS, and active in SAM.gov. The federal SDVOSB goal rose from 3% to 5%, so there's more set-aside volume chasing certified firms than ever. The good news on timing: SBA cleared its VetCert backlog to zero by November 2025 and average processing dropped to about 12 days.
8(a), HUBZone, and WOSB/EDWOSB
The 8(a) Business Development program is a one-time, nine-year term for disadvantaged-owned firms, and it got materially narrower: only 65 firms were admitted in 2025, down from 250 to 300 per year in the prior decade. The race-based presumption of social disadvantage has been suspended in practice since 2025, and on June 11, 2026 SBA issued a proposed rule (not yet final) to codify a race-neutral, fact-based standard. The practical effect already in force is that individually-owned applicants must prove social disadvantage with verifiable evidence rather than rely on a presumption; entity-owned firms (tribes, ANCs, NHOs) are unchanged. Economic-disadvantage thresholds are personal net worth under $850,000, three-year average AGI under $400,000, and total assets under $6.5M. HUBZone (rules effective January 2025) requires a principal office in a designated HUBZone and at least 35% of employees residing in one, and carries a 10% price-evaluation preference in full-and-open competition. WOSB/EDWOSB requires the firm to be small and at least 51% owned and controlled by women who are U.S. citizens, certified free through MySBA Certifications.
You can hold more than one lane
A firm can qualify for and hold multiple certifications at once: a veteran-owned, woman-owned engineering firm in a HUBZone could carry SDVOSB, WOSB, and HUBZone status simultaneously, each opening a different set of solicitations. Every one of them sits on top of an active SAM.gov registration with a current UEI. The certifications build on SAM, they don't replace it. The quarterback value is sequencing this correctly, SAM first, then the right lane or lanes, then the renewal and recertification cadence, so nothing lapses and you're eligible the day the right solicitation posts.
The roadmap
What we do, in order.
Scott owns each step and pulls in accredited specialists only where the rules require them.
Request an AssessmentConfirm your primary NAICS code (typically 541330 Engineering or 541310 Architectural) and verify you qualify as small against the current SBA size standard, averaging receipts over your last five fiscal years.
Gather core identity data: legal business name exactly as on IRS/EIN records, physical address, EIN/TIN, and banking information for the federal payment profile.
Register in SAM.gov: create the entity record, receive the auto-assigned 12-character UEI, and let SAM trigger the automatic DLA CAGE code.
Complete the SAM.gov Reps and Certs, select all applicable NAICS codes, activate the registration, and calendar the 365-day renewal as a hard deadline.
Determine which socioeconomic lane or lanes you qualify for, based on ownership, control, location, and the owner’s veteran or disadvantage status.
Apply through the correct portal: SDVOSB/VOSB via SBA VetCert (13 CFR Part 128); 8(a) and WOSB/EDWOSB via MySBA Certifications.
Maintain compliance: renew SAM annually, recertify each program on its cycle, and report material changes within the required windows.
Pursue set-aside and sole-source opportunities matched to your certifications, with Rule of Two awareness and the per-program sole-source ceilings.
Questions
Straight answers.
Do we still need a DUNS number to bid on federal work?
No. The DUNS number was retired on April 4, 2022 and replaced by the 12-character Unique Entity Identifier (UEI), which is assigned automatically and free when you register in SAM.gov. If anyone tells you to go get a DUNS number first, they're working from outdated guidance.
What's the difference between SAM.gov registration and an SBA certification, and which comes first?
SAM.gov registration comes first, always. It's the free, mandatory federal registration that issues your UEI and CAGE code and makes you eligible to receive a contract at all. SBA certifications (SDVOSB, 8(a), HUBZone, WOSB/EDWOSB) sit on top of that registration and open specific set-aside and sole-source lanes. They build on SAM, they don't replace it.
We are a veteran-owned engineering firm. Can we still self-certify as SDVOSB?
No, self-certification is over. The June 2024 SBA rule ended SDVOSB self-certification credit effective August 5, 2024, with a grace period that closed December 22, 2024. Only firms certified (or with a timely pending application) through SBA’s VetCert program now count toward SDVOSB goals or are eligible for set-aside and sole-source awards. The upside: SBA cleared its VetCert backlog by November 2025, processing now averages about 12 days, and the federal SDVOSB goal rose from 3% to 5%.
Does the 2026 change to the 8(a) program mean our firm cannot qualify anymore?
Not necessarily, but the path changed. The race-based presumption of social disadvantage has been suspended in practice since 2025, and on June 11, 2026 SBA issued a proposed rule (not yet final) to codify a race-neutral, fact-based standard. The practical effect already in force is that individually-owned applicants must prove social disadvantage with verifiable evidence. Entity-owned firms (tribes, ANCs, NHOs) are unchanged. The program is also much narrower now, with only 65 firms admitted in 2025, so it warrants a careful, evidence-driven application.
How do we know if our firm counts as 'small' for federal AEC work?
It depends on your primary NAICS code. For AEC that's usually Engineering Services (541330) at $25.5M in average annual receipts or Architectural Services (541310) at $12.5M, measured over your most recent five completed fiscal years. There's a key DoD wrinkle: 541330 carries a separate $47M exception for military and aerospace engineering, so a firm too large for civilian engineering can still be small for defense work. SBA has proposed raising these standards, but as of mid-2026 that's still proposed, so the current figures apply.
Can our firm hold more than one certification at the same time?
Yes. A firm can hold multiple certifications at once if it qualifies for each. A veteran-owned, woman-owned firm located in a HUBZone could carry SDVOSB, WOSB, and HUBZone status simultaneously, each opening a different set of solicitations. Every one of them sits on top of an active SAM.gov registration. The value of a quarterback is sequencing and maintaining all of them so nothing lapses and you’re eligible the day the right opportunity posts.
