Transwestern Carey Winston, L.L.C.

Transwestern Carey Winston, L.L.C., doing business as Transwestern Commercial Services, is a real estate services vendor that operates as a prime contractor on federal property and facility leasing, consulting, and buyer's representative services — entirely through full-and-open (non-set-aside) delivery orders. The company is structured as a for-profit limited liability partnership and is a subsidiary of Delta Transwestern Associates (as of 2023); it maintains a named subsidiary, Transwestern Delta Associates, L.L.C.

Transwestern's customer base is heavily concentrated in real property management and leasing. The General Services Administration Public Buildings Service accounts for 153 of 185 total awards (82% of recent award volume), substantially outpacing the Department of State Bureau of Overseas Building Operations (11 awards, $978 thousand combined potential value), the Department of Justice (7 awards, $1.5 million), and the Department of Defense Washington Headquarters Service (4 awards). The divergence between award count and potential value rankings reflects GSA PBS's massive volume of small-dollar orders against Transwestern's base, while DOJ and State carry fewer but larger individual actions. Nearly all work flows through GSA's Indefinite Delivery Contract SAQMMA17D0122, which anchors 10 task orders worth $853 thousand in combined potential value.

Transwestern's capability profile centers on real estate brokerage support, site information packages, real estate consulting, buyer's representative services, and lease/rental of office and commercial facilities for international properties. Recent work includes a $69,100 delivery order from State's Bureau of Overseas Building Operations for real estate services in Sweden (awarded June 15, 2026, completing July 20, 2026), a $61,000 order for international real estate consulting and information packages in Germany (awarded March 31, 2026, completing April 6, 2027), and a $123,500 delivery order for real estate consulting services and site information packages in Frankfurt, Germany (awarded April 18, 2022, completing January 30, 2026). Transwestern has served the Bureau of Overseas Building Operations continuously since at least 2001, with prior delivery orders ranging from $56,500 to $161,700.

Award activity remains sparse and episodic — one award in 2020, four in 2021, two in 2022, and two in 2026 — with combined potential value of $2.7 million against obligated dollars of $22.7 million, indicating substantial completion of prior multi-year work. Only two awards (combined potential value $130 thousand) complete within the next twenty-four months. The vendor does not subcontract; all 185 awards are prime work.
