Williams Scotsman Inc.

Williams Scotsman Inc., doing business as Willscot, operates as a prime contractor providing modular space solutions — mobile offices, storage containers, prefabricated structures, and specialized equipment rentals — to federal agencies across full-and-open competition, with no SBA set-aside designations. The company is a for-profit corporate entity headquartered in Phoenix, Arizona, and competes as a large business on its own merits rather than through socioeconomic set-asides.

The vendor's federal footprint reflects a highly fragmented customer base across 250 distinct agencies. The top-five customers by award count account for only 27 percent of recent awards and include the Department of the Navy Naval Sea Systems Command (216 awards, $2.1 million combined potential value), the Department of the Army (124 awards, $267 thousand), the Coast Guard (62 awards, $1.9 million), the Department of the Navy (63 awards, $7 thousand), and the Air Force (54 awards, $448 thousand). The potential-value ranking diverges sharply: the Department of Veterans Affairs Veterans Integrated Service Network 21 anchors the dollar stack (28 awards, $4.5 million), followed by VISN 1 (40 awards, $3.1 million), Naval Air Warfare Center (22 awards, $3 million), Naval Facilities Engineering Command (21 awards, $2.9 million), and Navy Installations Command (18 awards, $2.8 million). This spread reflects the vendor's core model: high volume of small, short-term rentals at individual agencies alongside lower-volume, longer-duration multi-million-dollar leases at medical centers and major installations.

Willscot holds two primary vehicle positions. The General Services Administration Multiple Award Schedule (established June 2023, ceiling $750 thousand through June 2028) carries 994 task orders valued at $164.5 million in combined potential value and serves as the operating backbone for federal procurement. Representative MAS-based awards include $816.7 million delivery order from Army Test and Evaluation Command (October 2025) for trailers at Dugway, Utah; $523.8 million delivery order from Naval Facilities Engineering Command for Red Hill trailers (January 2025); $448.4 million delivery order from Naval Air Warfare Center for B149T relocatable lease in Phoenix (November 2024); and $915.1 million delivery order from Air Force Special Operations Command for 12,500-square-foot modular facility at Cannon AFB, New Mexico (April 2026). A single-award Indefinite Delivery Contract with the Department of Agriculture's Cotton and Tobacco Program (ceiling $82.85 thousand, expiring September 2026) supports storage container rentals for cotton samples. The vendor also holds a Blanket Purchase Agreement with Fish and Wildlife Service Region 3 for mobile office rental at Swan Lake National Wildlife Refuge, Missouri (ceiling $46.8 thousand, running through December 2030).

Recent prime activity totals 1,892 awards with combined potential value of $221.4 million, of which $129.3 million (58 percent) has been obligated. The award trajectory shows growth from 50 awards in 2022 to a peak of 124 in 2024, declining to 73 in 2025 and 23 year-to-date in 2026 (partial-year data as of July 8, 2026). The prime-versus-sub split favors prime work: 86 percent of awards are prime contracts or IDVs; 14 percent are sub-awards. Recompete exposure within the next twenty-four months stands at 27 awards valued at $2.8 million in combined potential value.

NAICS coding shows Willscot's commodity focus: Manufactured Home (Mobile Home) Manufacturing anchors 995 awards, followed by Ship Building and Repairing (148), Lessors of Nonresidential Buildings (113), Truck Utility Trailer and RV Rental and Leasing (84), and Other Commercial and Industrial Machinery Rental (48). PSC concentration centers on Prefabricated and Portable Buildings (387 awards), Lease or Rental of Equipment–Prefabricated Structures and Scaffolding (161), Lease or Rental of Equipment–Ground Effect Vehicles, Motor Vehicles, Trailers (151), Trailers (148), and Lease/Rental of Office Buildings (57).

In its subcontractor role, Willscot supplies modular and office trailers, storage containers, and specialized equipment rentals to major defense primes and environmental remediation contractors. Recent subs include work under Huntington Ingalls for USS Boise Engineered Overhaul (office trailer leases, multiple modifications through June 2024), BAE Systems Maritime Solutions Norfolk for USS Kearsarge and USS Nitze equipment rental (direct equipment support for docking selected restricted availabilities), Weston Solutions for fire fuel farm repair and cooling water supply projects at Buckley AFB (rental services), Turner Construction for construction trailer rental on Arnold AFB DRAGONFIRE facility and FARM II projects, and Vigor Marine for USS John S. McCain and USS New York ship repair availabilities (office and CONEX rentals with furniture and support).

The vendor's federal contracting track record extends since 2002, demonstrated by documented awards spanning VA medical centers, Coast Guard facilities, Army installations, Naval shipyards, Air Force bases, and civilian agencies including NIH, Interior, Agriculture, and Defense Health Agency. The company operates an approximately 100,000-unit modular fleet across North America and delivers lease, rental, sale, and installation services without set-aside restrictions, positioning it as a commercial-scale vendor competing head-to-head with other large providers in the modular infrastructure space.
