About 400 Courthouse Square, Alexandria, LLC
400 Courthouse Square, Alexandria, LLC (doing business as Westin Alexandria) operates the Westin Alexandria hotel in Alexandria, Virginia as a prime contractor delivering lodging, meeting space, audiovisual equipment, and conference services to federal agencies on a full-and-open, non-set-aside basis. The vendor holds three single-award Blanket Purchase Agreements anchoring its federal footprint: a $10 million NIH BPA (Office of Logistics and Acquisition Operations) through December 2025, a $790,000 USPTO BPA through July 2030, and a newly awarded $1.5 million Defense Health Agency BPA through December 2028.
The vendor's customer concentration is sharply anchored by dollar value. The top customer by potential value is NIH's Office of Logistics and Acquisition Operations at $10 million (one award, the master BPA), which represents 79% of the vendor's combined potential value across all awards. By award count, concentration is more distributed: the Defense Health Agency (6 awards, $1.9 million), USPTO (6 awards, $220 thousand), and Treasury Departmental Offices (6 awards, $119 thousand) lead volume, with NIH's Center for Scientific Review trailing at 3 awards ($78 thousand) — reflecting call-order activity under the larger NIH master BPA. Recent work includes a $52,887 purchase order from USPTO for Patents Day meeting space (July 2026), a $15,373 NSF call for workshops and audiovisual support in Stony Brook, New York (January 2026), a $148,519 Defense Health Agency call for DMHRS-I training conference lodging and facilities (April 2024), and multiple $27,000–$35,000 NIH peer review calls under the master BPA.
The vendor's capability portfolio is concentrated in hotels and motels (29 of 31 awards, per NAICS); the remaining two awards reflect professional training. Performance service codes span lodging and hotel/motel procurement (15 awards), conference space and facilities lease/rental (12 awards), and miscellaneous support services (2 awards). All work is performed at the Westin Alexandria property in Alexandria, Virginia or at subordinate federal sites requiring temporary lodging and meeting support — the NSF contract named Stony Brook, New York as a subordinate performance location.
Activity has fluctuated modestly: 1 award in 2022, climbing to 5 in 2023 and 7 in 2024, then declining to 5 in 2025 and 2 in 2026 to date. Only one award (combined potential value $53 thousand) faces ultimate completion within the next twenty-four months, presenting minimal recompete exposure. The vendor's subcontract footprint is negligible (1 of 31 awards, 3% of total): a single conference services sub-award under Sri International on a federal grant (September 2024). Combined obligated dollars total $1.2 million against $12.6 million combined potential value (9% obligation rate), reflecting the vendor's reliance on task-order call activity rather than firm fixed-price delivery orders.
