Which subcontractors or suppliers have been named for the White House Ballroom project?

1. Who the headlines name: the core team identified publicly

When the ballroom project was announced, reporting and a Senate inquiry list three principal participants: McCrery Architects as the original designer, AECOM as the engineering firm, and Clark Construction as the general contractor leading a consortium awarded the job ^{[1] [2]}. Congressional correspondence from Sen. Richard Blumenthal explicitly names those three firms as the architect, engineer and builder tied to the project ^[1]. A contemporary account also says a Clark-led consortium received a roughly $200 million award in August 2025 ^[2].

2. A late-stage design change: Shalom Baranes joins the team

By early December 2025, a cluster of outlets reported that Shalom Baranes Associates — a well-known Washington, D.C., architectural firm — had been brought onto the project to “pick up the design” or lead the next phase, displacing or supplementing McCrery Architects amid reported capacity and scheduling problems ^{[2] [3] [4] [5]}. Coverage ranges from describing Baranes as an added firm to saying McCrery would remain in a consulting role ^{[2] [4] [5]}.

3. What the sources agree on — and where they differ

Sources consistently identify McCrery, Clark and AECOM as early named participants and concur that Shalom Baranes was added or tapped later ^{[1] [2] [3]}. They diverge on the precise status of McCrery — some outlets say McCrery stepped aside but will remain a consultant, while at least one White House official quoted in reporting denied McCrery was fired ^{[4] [5]}. Reported seat counts and square footage have also fluctuated across stories, underscoring shifting project scope alongside contractor changes ^{[2] [6]}.

4. Subcontractors and suppliers: what reporting does — and does not — say

Available reporting names the lead firms and donors but does not publish a roster of subcontractors or trade suppliers engaged on-site. The Senate letter asks for records of subcontractor agreements and terms, implying those details exist but have not been publicly released ^[1]. News stories and the donor list reporting do not enumerate specific plumbing, electrical, glazing, or MEP subcontractors ^{[7] [8]}. In short: public reporting names lead architect, engineer and main contractor — it does not list the subcontractor or supplier firms by name ^{[1] [7] [8]}.

5. Why subcontractor names matter — and why they may be withheld

Sen. Blumenthal’s inquiry requests subcontractor agreements and selection terms, signaling congressional interest in how private firms became part of a high-profile project that required demolition of the East Wing ^[1]. Standard practice in large construction contracts is that subcontractor assignments can be negotiated by the prime contractor and may not be disclosed publicly until contracts are executed; reporting to date shows officials have not publicly released that level of detail ^{[1] [8]}. Available sources do not mention specific subcontractor identities.

6. Donors, procurement concerns and potential conflicts

Reporting has focused on who is funding the privately financed $200–$300 million build and on whether the project followed permitting and selection norms. A donor list was released for fundraising transparency but not tied to procurement of subcontractors and suppliers; outlets note concerns about zoning, permitting and the speed of demolition and construction activity ^{[7] [9] [10]}. The Senate letter frames procurement transparency as a public-interest question ^[1].

7. How to get definitive answers

For named subcontractors and suppliers, the next reliable sources would be: contract documents produced in response to Sen. Blumenthal’s request; filings or submissions to the National Capital Planning Commission or other permitting authorities that list contracted parties; or public disclosures by Clark Construction or the engineering/architect firms. Current reporting does not cite such documents ^{[1] [8]}. Available sources do not mention a public list of subcontractors or suppliers.

8. Bottom line

Public reporting names McCrery Architects, AECOM and Clark Construction as the initial architect, engineer and builder for the White House Ballroom; it documents the addition of Shalom Baranes Associates to lead design work in December 2025 ^{[1] [2] [3] [4]}. However, none of the sources provided list individual subcontractors or suppliers by name — and a Senate inquiry is actively seeking those contractual details ^[1].
