About this opportunity
The Department of Defense Washington Headquarters Service awarded contract HQ003426PE099 to Geophysical Survey Systems, Inc. (GSSI) on a sole-source basis for purchase, shipment, and support of a GSSI SIR 400 HyperStacking 350 MHz ground penetrating radar system and accessories, with an estimated contract value of $38,729.64.
The Defense Prisoner of War/Missing in Action Accounting Agency (DPAA) justified the sole-source procurement under FAR Part 12 simplified procedures for commercial items based on DPAA's established validation and accreditation of GSSI equipment under American National Standards Institute guidelines. GSSI is the exclusive system validated under DPAA's ANAB accreditation and is recognized as the industry leader in high-resolution geophysical remote sensing for archaeological applications. The equipment must be compatible and interoperable with existing GSSI equipment already owned by DPAA and has been field-tested for locating archaeological features including mass graves and aircraft impact craters to guide excavation operations. Market research conducted March 9–11, 2026, identified no alternative vendors meeting DPAA's technical, regulatory, and ANAB accreditation requirements. Procuring from alternative contractors would require DPAA to halt operations, conduct lengthy validation processes, and establish new data comparability standards, introducing unacceptable operational delays. The justification was approved July 6, 2026. Funding is provided through Operations and Maintenance appropriation. Work is performed on behalf of DPAA, with place of performance not specified in the source.
