A small business shut out of a Navy construction pool lost its protest because it filed too late. GAO never looked at whether the Navy evaluated it fairly. In a decision dated October 19, 2026, the Government Accountability Office dismissed the protest of Encon Desbuild JV4, LLC (EDJV4), which challenged its exclusion from phase one of a Naval Facilities Engineering Systems Command (NAVFAC) design-build procurement worth up to $1.5 billion. The Hyattsville, Maryland joint venture waited for what the contracting officer called a debriefing. GAO held that calling it a debriefing did not extend the filing deadline.
The decision, B-423574.2, appeared on GAO's recent bid protest decisions page on October 23. The lesson for small construction firms is short. In a two-phase design-build competition, the 10-day protest clock runs from when you learn the basis of your protest, such as receiving the agency's assessment of your phase-one proposal, not from the end of a later question-and-answer exchange.
What NAVFAC Is Buying With the $1.5 Billion Pool
NAVFAC issued Request for Proposals No. N69450-25-R-0011 on May 1, 2025, for general construction and design-build construction projects in the southeastern United States. The Navy set the competition aside entirely for small businesses and ran it as a two-phase design-build selection under Federal Acquisition Regulation subpart 36.3.
The solicitation set a total not-to-exceed amount of $1.5 billion across all of the indefinite-delivery, indefinite-quantity contracts it would produce. The Navy planned about eight awards. Each contract would run one base year plus four one-year options.
Under the two-phase method, the agency first reviews offerors' qualifications, such as experience and past performance, and picks a limited group to move on. Only that group submits full technical and price proposals in phase two. EDJV4 did not make it past phase one.
How the Protest Timeline Unfolded
The Navy notified EDJV4 on June 2, 2026, that it had not been selected for phase two. On June 24 the Navy gave the firm a written phase-one debriefing containing its assessment of the firm's phase-one proposal. EDJV4 sent follow-up questions on June 26, and the Navy answered on July 9.
EDJV4 filed its protest with GAO on July 20, 2026, seven weeks after the exclusion notice and nearly four weeks after the June 24 assessment. The firm argued that the Navy unreasonably assessed various significant weaknesses under the past performance factor. It also argued that the Navy never gave it a chance to address adverse past performance information before relying on it.
A protester who raises adverse past performance it never had a chance to rebut can sometimes win on the merits. EDJV4 never got that far.
Why the Debriefing Label Did Not Save EDJV4's Protest
GAO's timeliness rules generally require a protester to file within 10 days of when it knew or should have known the basis for its protest. The main exception covers procurements conducted on the basis of competitive proposals, where the offeror requests a required debriefing. In those cases, a protester may wait for the debriefing and file within 10 days after it.
EDJV4's case depended on that exception. If the June 24 debriefing counted as a required debriefing, the protest could be timely. If it did not, the 10-day period ran from when EDJV4 received the Navy's assessment, and July 20 was too late.
GAO concluded that the two-phase design-build procedures of FAR subpart 36.3 govern phase one, so the phase-one debriefing was not a required debriefing. Without that, the required-debriefing exception did not apply. GAO also addressed the contracting officer's reference to Revolutionary FAR Overhaul (RFO) section 15.206, finding that it did not change this result.
The decision states that "the debriefing exception to our timeliness rules does not apply and therefore EDJV4's protest is untimely." GAO's conclusion followed in one line: "We therefore dismiss the protest as untimely." GAO noted that EDJV4 "was provided with the agency's assessment of the firm's phase one proposal on June 24, but EDJV4 did not file its protest until July 20."
GAO did not rule on whether the Navy's past performance evaluation was reasonable or whether it should have let EDJV4 respond to the adverse information. The dismissal ends the protest on procedure alone.
Why the Phase-One Distinction Matters Beyond This Case
Two-phase design-build is a common way for agencies to buy construction, especially in multiple-award pools like this one, where a large field of small businesses competes for a limited number of phase-two slots. Phase one cuts the field. For most offerors that cut is the decisive moment, because firms excluded there never submit full proposals.
A firm excluded in phase one may reasonably think it can wait for a debriefing before deciding whether to protest. Contracting officers often give such firms a written explanation, and they may use the word "debriefing" or cite FAR part 15. GAO's decision shows that the agency's label does not decide the timeliness question. The nature of the procurement stage does. A post-exclusion explanation under subpart 36.3 does not carry the debriefing exception.
Follow-up questions do not help either. EDJV4 asked questions on June 26 and got answers on July 9. Those exchanges did not move the deadline.
What It Means for Contractors
Small businesses competing in two-phase design-build procurements should treat the phase-one exclusion and assessment as the start of the protest clock. In this case, the protest came nearly four weeks after the June 24 assessment, and seven weeks after the June 2 notice.
Several practical steps follow from the decision:
- Calendar the exclusion notice and assessment. When an agency tells you that you were not selected to advance in a two-phase design-build competition, count 10 days from when you learn the basis of your protest unless you have a clear legal basis to rely on a different trigger.
- Do not rely on the agency's label. A contracting officer who calls a phase-one letter a debriefing, or cites FAR 15.206, does not by doing so create a required debriefing that extends your deadline.
- File with what you have. If the assessment tells you enough to identify a protest ground, such as significant weaknesses you dispute or adverse past performance you never had a chance to address, file on that basis. Supplemental grounds can come later if new information surfaces.
- Keep asking questions, but separately. Questions to the contracting officer can help you understand the evaluation. They do not stop the clock, so run them alongside a timely protest, not in place of one.
- Push on past performance during phase one. If you know of adverse past performance information an agency might use, consider how and when the solicitation lets you address it, because a late protest cannot fix that problem afterward.
For EDJV4, the past performance arguments may have had merit. Because the protest was untimely, no one at GAO decided whether they did.
