The Government Accountability Office has ordered the Army to reopen a $50 billion professional-services contract after finding the service unlawfully blocked small businesses from teaming up as informal subcontractors, according to a decision published by GAO sustaining a protest from Intelligence Consulting Enterprise Solutions, Inc.
Background
The Army built its Marketplace for the Acquisition of Professional Services, known as MAPS, by consolidating two existing professional-services indefinite-delivery, indefinite-quantity vehicles into a single contract with a $50 billion ceiling. Combining two vehicles into one competition of that size gives the terms governing who can bid outsized weight for the professional-services industry. The solicitation, No. W15P7T26RA006, drew a protest from Intelligence Consulting Enterprise Solutions, Inc., a small business that challenged multiple terms of the competition, including how the Army structured eligibility for small firms that wanted to combine forces on a proposal.
GAO decided the case, docketed as B-424433.3 and B-424433.7, in a decision dated Aug. 11, 2026, and published Aug. 12. The office sustained one of ICES's grounds and denied the rest, ordering corrective action on the winning issue while leaving the balance of the solicitation intact. Because GAO is the forum Congress designated to resolve bid protests, its decision is binding on the Army's next steps for the procurement.
Key Details
The sustained protest ground centered on how small businesses could structure their bids. The Army's solicitation required small businesses to form joint ventures if they wanted to combine forces on a proposal, and did not allow them to submit as informal small-business teams of subcontractors instead. GAO found that restriction unlawful under the Small Business Act, specifically 15 U.S.C. §§ 644(e)(4)(A), 644(e)(1) and 644(q)(1)(A).
GAO wrote that the statute "creates a positive right for 'a small business concern' ... to 'submit an offer' using either a small business team of subcontractors or a joint venture," and held that the choice between those two structures belongs to the small business, not the contracting agency. The decision states that the Army's restriction "thwarts the underlying purpose of the relevant statutory framework" because it reduces, rather than expands, small-business participation in the competition.
ICES raised several other challenges that GAO denied. The protester argued the Army mishandled how it numbered and posted solicitation amendments, but GAO found ICES had actual notice of the changes regardless of any procedural irregularity. ICES also objected to a solicitation term barring offerors from citing classified contracts as past performance references; GAO found the Army offered a rational justification tied to security and administrative burden. A third denied ground involved ICES's complaints about the adequacy of the Army's responses to offeror questions.
On the sustained ground, GAO recommended that the Army amend the solicitation to permit small-business teams to compete alongside small-business joint ventures, then reopen the competition and give offerors a reasonable period to submit new or revised proposals. GAO also recommended that the Army reimburse ICES for the costs of pursuing the protest, including reasonable attorneys' fees. Notably, GAO's remedy does not scrap the MAPS solicitation or restart the procurement from scratch; it targets the single defective term and leaves the rest of the competition, including the amendment-numbering process and the classified-past-performance restriction GAO upheld, in place.
What It Means for Contractors
The decision reopens one of the largest professional-services vehicles the Army has assembled in recent years, and it does so on terms that directly expand who can compete and how. Small businesses that sat out the original MAPS solicitation because they lacked a joint-venture partner, or because forming one on short notice was impractical, now have a path back in as an informal teaming arrangement once the Army issues its amendment.
Firms that already submitted proposals under the original rules should watch for the amendment closely. A reopened competition with a new proposal deadline gives every offeror, not just ICES, a chance to reconsider teaming strategy, adjust pricing, or bring in new subcontractors now that the joint-venture requirement is gone. Prime contractors that had structured joint ventures specifically to satisfy the original restriction may want to evaluate whether an informal teaming arrangement now serves their proposal better, since joint ventures carry formation costs and shared liability that a subcontracting team does not.
The ruling also has weight beyond MAPS. Other agencies drafting large IDIQ solicitations that funnel work to small businesses now have a clear signal that restricting offerors to joint ventures alone, when the underlying set-aside or reserve authority derives from the cited Small Business Act provisions, invites a sustained protest. Agencies structuring similarly large consolidated vehicles should expect contracting officers to revisit teaming clauses before solicitations go out, rather than risk a corrective-action order after award activity is already underway.
For small businesses generally, the decision reinforces that agencies cannot use solicitation drafting to narrow the statutory options Congress gave them for combining forces on a bid. Firms weighing whether to protest a solicitation term that forces a particular teaming structure now have a recent, on-point precedent to cite. The denied grounds are instructive too: GAO continues to defer to agencies on past-performance restrictions tied to classified work when the agency articulates a rational basis, and actual notice of an amendment can defeat a procedural challenge over how that amendment was numbered or posted, regardless of whether the agency's process was tidy.
With the recommendation for cost reimbursement, the Army also absorbs the expense of ICES's protest on top of the delay to a $50 billion vehicle, a reminder that solicitation terms restricting statutory teaming rights carry real cost even when most of a protest's other grounds fail. The Army has not yet said when it will issue the amendment or set a new proposal deadline, but firms that plan to compete for MAPS work should prepare both joint-venture and informal-team proposal structures so they can move quickly once the reopened solicitation is issued.
Contracting officers assembling large multiple-award or IDIQ vehicles elsewhere in the Army, and across the Department of Defense more broadly, now have a concrete example of what GAO will not accept: a solicitation clause that forces small businesses into one specific teaming structure when the statute leaves the choice to the small business. Legal and capture teams reviewing draft solicitations for similar consolidated vehicles should flag any clause that mandates joint ventures as the sole path for teaming small businesses, since this decision gives protesters a ready template for challenging it before proposals are even due, not just after an award.
