400 Courthouse Square, Alexandria, LLC

400 Courthouse Square, Alexandria, LLC (doing business as Westin Alexandria) is a for-profit hospitality and event services provider offering temporary lodging, conference facilities, meeting space rentals, and audiovisual equipment to federal agencies as a prime contractor (97% of recent awards), competing in full-and-open procurements with no set-aside designations across its portfolio.

The Westin Alexandria's capability portfolio is concentrated in hotel accommodations, event venue provisioning, and conference support. The vendor operates the Westin Alexandria hotel at its headquarters location in Alexandria, Virginia, and delivers lodging, meeting rooms, and AV services on-demand through blanket purchase agreements and individual purchase orders. Representative work includes a $10 million single-award BPA with the National Institutes of Health Office of Logistics and Acquisition Operations (awarded October 2023, running through December 2025 for ordering, with calls issued through 2028) for hotel rooms, conference space, and AV equipment rentals nationwide; a $1.5 million single-award BPA with the Defense Health Agency (awarded December 2025, running through December 2028) for meeting space, audiovisual equipment, and support services; a $148.5 thousand purchase order from the Defense Health Agency in April 2024 for lodging and conference facilities supporting the Defense Medical Human Resources System-Internet training conference; and a $52.3 thousand purchase order from the National Science Foundation in November 2024 for the Alan T. Waterman Awards Event ceremony and location.

Customer concentration is heavily anchored by the NIH BPA. The top five customer agencies by potential value account for 98% of recent awards, dominated by the National Institutes of Health Office of Logistics and Acquisition Operations ($10 million combined potential value from one award, the single-award BPA), followed by the Defense Health Agency ($1.9 million across six awards), the U.S. Patent and Trademark Office ($209 thousand across six awards), the Department of the Treasury ($119 thousand across six awards), and the U.S. Coast Guard ($79 thousand). By award count, the USPTO, Treasury, and Defense Health Agency each account for six awards, while NIH's Center for Scientific Review holds three. The disconnect between rankings reflects the NIH BPA's outsized dollar value anchoring the potential-value rankings despite NIH appearing in only four award records.

The vendor holds a single active parent vehicle: the NIH BPA (75N98024A00003), from which three task orders have been placed totaling $78 thousand in combined potential value. The Defense Health Agency and USPTO BPAs are vehicle holders as well but appear in the source's vehicle holdings with no task-order data. Activity has grown episodically, with five awards in 2023, seven in 2024, five in 2025, and two in 2026 to date. Eleven awards representing $1.1 million in combined potential value reach ultimate completion within the next twenty-four months, exposing the vendor to recompete timing primarily on smaller purchase orders and potential renewal calls under the NIH and Defense Health Agency BPAs. Combined obligated dollars across all awards total $1.2 million (9% of the $12.6 million combined potential value), reflecting the BPA's large ceiling relative to drawdown. The vendor subcontracts minimally; one grant sub-award appears in the source, a conference services sub-award to Sri International in September 2024. Primary NAICS concentration is 445100 (Hotels except Casino Hotels and Motels) across 29 of 31 awards; PSC concentration aligns with lodging and facility rentals (15 awards under Transportation/Travel/Relocation—Lodging, Hotel/Motel; 12 under Lease/Rental of Conference Space and Facilities).
