Mcgrath Rentcorp

McGrath Rentcorp, doing business as Mobile Modular, manufactures and leases prefabricated modular office trailers, temporary facilities, storage containers, and specialized building structures to federal agencies as a prime contractor (89% of recent awards) competing full-and-open with no set-aside designation across its portfolio. The company is a for-profit corporation headquartered in Livermore, California, with subsidiary operations through Adler Tank Rentals LLC and Vesta Housing Solutions LLC that extend its modular infrastructure capability across rental and housing verticals.

McGrath Rentcorp's federal footprint centers on temporary and modular facility leasing. Recent prime contract work spans the Department of Interior ($4.9 million across five Bureau of Reclamation awards for temporary infrastructure), the Department of the Air Force Materiel Command ($1.9 million across six awards for modular trailer leases including ALIS trailer renewal for JSF program support), the Air National Guard ($1.7 million across eleven awards for temporary facilities at Moffett Federal Airfield and other bases), and the Army Corps of Engineers ($627 thousand across eight awards for construction office trailers at Pajaro Reach and Ice Harbor Dam). Representative awards include a $276,405 delivery order for office trailer rental in Burbank, Washington (Army Corps of Engineers, September 2024), a $253,085 option year three delivery order for modular office building rental in Flagstaff, Arizona (Interior Southwestern Region, August 2023), and a $185,976 firm fixed-price delivery order for temporary facilities supporting Building 650 at Moffett Federal Airfield (Air National Guard, August 2025). All work operates under full-and-open competition; the source notes one small-business set-aside designation (a $125,454 custom bunk house to DoD Southwest Region, June 2024) but McGrath competes predominantly unrestricted.

Customer concentration is fragmented. The top five customer agencies by award count account for 33% of awards, led by the Department of the Navy (49 awards) and the Army Acquisition Support Center PEO Missiles and Space (27 awards), followed by Forest Service Region 5–Pacific Southwest, Navy Office of Naval Research, and the Army. The top five by dollar value account for 29% of combined potential value, anchored by Interior Bureau of Reclamation (five awards, $4.9 million). This spread across 95 distinct customer agencies reflects McGrath's role as a broad-based infrastructure supplier to civilian and defense agencies at multiple operational levels, with no single customer dominating either count or dollars.

McGrath holds seat on the GSA Multiple Award Schedule (MAS) as its primary parent vehicle, with 72 task orders carrying $14.8 million in combined potential value. The company also participates in the Advanced Technology Support Program IV (27 task orders, scope unclear from sub-award descriptions) and holds indefinite delivery contracts with the Navy (N0022886L3168 with four task orders, N6247021D0007 with three). The MAS position is the backbone of McGrath's federal footprint, allowing it to place delivery orders across Interior, Agriculture, Labor, Commerce, and Defense agencies without repeated competitive solicitation.

Activity has grown modestly, from fifteen awards in 2022 to thirty-one in 2025, with only two awards recorded in the 2026 partial year (award data through June 19, 2026). Seven awards totaling $872 thousand in combined potential value face ultimate completion inside the next twenty-four months, representing modest recompete exposure for McGrath and limited near-term revenue cliff.

McGrath subcontracts to major primes on specialized projects. Northrop Grumman Systems Corporation receives McGrath fabrication and leasing support across the Advanced Technology Support Program (ATSP) for prefabricated metal building and component manufacturing supporting microelectronics-based aircraft systems (multiple sub-awards September 2025 onward). Bechtel National receives modular trailer support for NASA Space Launch System Mobile Launcher 2 construction (sub-awards February 2025, June 2024, November 2023). Ch2M Hill engages McGrath for office trailer rentals supporting environmental remediation and program management (sub-awards July 2025, February 2025, August 2024). Additional subs include Hanford Tank Waste Operations & Closure LLC, GE Renewables US LLC, and Astrion Group LLC across modular build, renovation, and temporary facility placements.

The primary NAICS and PSC framing underscores McGrath's core market: Lessors of Nonresidential Buildings (except Miniwarehouses) account for 106 awards; Prefabricated Metal Building and Component Manufacturing and Engineering Services each hold 31 awards. Top PSCs include Lease or Rental of Equipment–Prefabricated Structures and Scaffolding (60 awards) and Prefabricated and Portable Buildings (54 awards). This concentration signals McGrath competes in a narrow, specialized procurement space where federal agencies require temporary or modular facility solutions rather than permanent construction, with revenue driven by lease terms rather than one-time builds. The company's federal market is stable and recurring across civilian agencies (Forest Service firefighting operations, Interior visitor centers, Agriculture field stations) and defense installations (Air Force, Navy, Army bases) rather than concentrated in single large programs, making it a reliable but non-critical supplier in the federal infrastructure logistics ecosystem.
