Williams Scotsman Inc.

Williams Scotsman Inc., doing business as Willscot, is a for-profit corporation based in Phoenix, Arizona that leases, rents, and sells modular buildings, office trailers, portable classrooms, storage containers, and related temporary infrastructure solutions to federal agencies as a prime contractor (85% of recent awards) and occasional subcontractor. The company operates a fleet of approximately 100,000 modular units across North America and competes on a full-and-open basis with no SBA set-aside designations across its federal footprint.

Williams Scotsman's customer base is broad and distributed across 253 federal agencies, with concentration split between volume and dollar value. By award count, the top customer segment includes the Department of the Navy Naval Sea Systems Command (217 awards, $2.1 million combined potential value), the Department of the Army (124 awards, $267 thousand), and the Department of Homeland Security U.S. Coast Guard (63 awards, $1.8 million), accounting for 27% of all awards. By potential dollar value, the Department of Veterans Affairs Veterans Integrated Service Network 21 leads (28 awards, $4.5 million), followed by Veterans Integrated Service Network 1 (40 awards, $3.1 million) and the Naval Air Systems Command Naval Air Warfare Center (22 awards, $3 million). The divergence signals that Navy SYSCOM generates high-frequency small orders while VA healthcare systems anchor larger multi-year leases. Recent representative work includes a $915 thousand modular facility lease at Cannon Air Force Base, New Mexico under the GSA Multiple Award Schedule through Air Force Special Operations Command; a $523 thousand base-year trailer lease for Red Hill at Naval Facilities Engineering Command through January 2027; and a $816 thousand lease for single-wide and double-wide portable trailers at Dugway, Utah supporting the Army Test and Evaluation Command through September 2030.

Williams Scotsman's primary vehicle is the GSA Multiple Award Schedule (MAS), against which 995 task orders have been placed for a combined $164.4 million potential value. This vehicle, established June 2023 with a $750 thousand ceiling through June 2028, is the operating backbone of Willscot's federal modular space rental portfolio and serves as the contracting mechanism for task orders across Defense, VA, Coast Guard, and civilian agencies. The vendor also holds a single-award Indefinite Delivery Contract with the Department of Agriculture Cotton and Tobacco Program for storage container rental valued at $82,850 through September 2026, and a Blanket Purchase Agreement with the Department of Interior Fish and Wildlife Service Region 3 for mobile office rental at Swan Lake National Wildlife Refuge, Missouri through December 2030. The company's NAICS concentration reflects its core business: Manufactured Home (Mobile Home) Manufacturing (996 awards), Lessors of Nonresidential Buildings (113 awards), and Truck, Utility Trailer, and RV Rental and Leasing (85 awards).

Activity has grown from 50 awards in 2022 to 125 in 2024, with a moderation to 74 awards in 2025 and 30 through early October 2026. Nineteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $2.1 million, representing moderate recompete exposure. In its subcontractor role, Williams Scotsman delivers equipment rentals to major defense primes including BAE Systems Maritime Solutions Norfolk and Jacksonville, Huntington Ingalls, Vigor Marine, and others on naval ship availability and modernization work, as well as to environmental and construction primes including Weston Solutions, AECOM Technical Services, and Turner Construction. The company's sub-award footprint is dominated by equipment rental for Navy ship maintenance availabilities (docking selected restricted availabilities, post-shakedown availabilities, and overhaul work), as well as office trailers and CONEX containers for environmental remediation, construction, and facility modernization projects.

SCI-reported invoiced revenue on federal service contracts above the $150,000 threshold totaled only $379 in FY2025, reflecting Williams Scotsman's business model: the vast majority of federal revenue flows through goods procurement (equipment lease and rental) and delivery orders under IDVs rather than through billable labor-hour service contracts. The company carries minimal subcontractor engagement on primes (0% average sub-hours share across SCI-reportable contracts), indicating it builds its own delivery and logistics teams for equipment placement, maintenance, and removal. Williams Scotsman's federal footprint is characterized by high frequency, modest-dollar transactional work—short-term emergency rentals, routine lease renewals, and specialized equipment provisioning—distributed across the federal government, with concentration anchored by long-term VA healthcare system lease agreements and recurring Navy ship maintenance support.
