About the company
HR Wallingford LIMITED, a United Kingdom-based international nonprofit organization, provides hydraulic modeling, ship navigation simulation, coastal engineering research, and specialized maritime equipment to the U.S. Army Corps of Engineers and the Department of the Navy as a prime contractor (95% of recent awards), competing without set-aside designation on full-and-open procurements. The vendor has maintained a federal presence since at least 2001 and is registered in SAM.gov as a non-profit entity.
HR Wallingford LIMITED's federal footprint concentrates entirely within the Department of the Army and the Department of the Navy, with 84% of awards funding Army programs. The top customer by both volume and potential value is the Army Corps of Engineers' Engineer Research and Development Center (ERDC), which accounts for 10 awards worth $8 million combined potential value. The Corps of Engineers overall (including ERDC and Civil Works divisions) controls 17 of the 43 tracked awards and $10.2 million of the $10.8 million combined potential value. The Office of Naval Research accounts for 3 awards worth $453 thousand. Obligated value across all awards stands at $7.9 million (73% of combined potential value), signaling consistent delivery and invoicing across the portfolio.
The vendor's primary vehicle is the Army Corps of Engineers' single-award Indefinite Delivery Contract W912HZ25D0001, valued at $7.37 million through November 2025, which provides transitional support for the ERDC Ship/Tow Simulator program. Six delivery orders totaling $539 thousand have been issued under this IDC for ship and tow pilot professional services, vessel model and database validation, and simulation trials, with completion dates extending through April 2028. Representative recent prime work includes a $184.5 thousand delivery order (April 2025) for simulation trials under the IDC, a $152.2 thousand delivery order (February 2026) for ship and tow pilot services supporting the Elizabeth River in Virginia, a $125.2 thousand delivery order (November 2025) for vessel model validation performed in Great Britain, and a $1.19 million definitive contract (August 2021) for purchase and delivery of a directional spectra wave generator with active absorption to replace equipment at ERDC's Vicksburg, Mississippi facility. The vendor also holds federal grant positions as prime recipient under Army Corps of Engineers cooperative agreements: a current award (September 2024) for numerical modeling of fluid sediments and vessel navigation simulation extending through June 2027, and a prior cooperative agreement (September 2022–September 2023) on similar modeling work.
Activity has remained modest and flat—one award in 2022, two in 2023, five in 2024, five in 2025, and two through February 2026—with six awards (combined potential value $539 thousand) completing within the next twenty-four months and therefore facing recompete exposure. The vendor maintains a minimal subcontract footprint, performing 2D and 3D physical modeling services as a subcontractor to Mdpac JV on two naval facility engineering and design orders (Tinian Wharf Improvements and Apra Harbor Waterfront Repairs, awarded March 2024 and January 2024 respectively). HR Wallingford LIMITED's capability portfolio centers on vessel simulation, hydraulic modeling, coastal and maritime engineering research, and specialized wave-generation and propeller-dynamometer equipment for federal laboratory and research infrastructure, with work performed across U.S. sites (Vicksburg, Mississippi; Boston, Massachusetts; Grand Rivers, Kentucky; Washington, DC; and Virginia) and the United Kingdom.
