About the company
GSI Hawaii Inc., a Native Hawaiian organization-owned, minority-owned small business certified in the SBA 8(a) Business Development Program through June 2032, delivers construction quality management, medical facilities support, infrastructure repair, and environmental staffing services to federal agencies as a prime contractor (83% of recent awards) based in Honolulu, Hawaii. The vendor competes predominantly under 8(a) sole-source set-asides, with recent awards split between sole-source and full-and-open designations. GSI Hawaii is a subsidiary of Native Hawaiian Community Development Corporation, a not-for-profit Native Hawaiian organization that serves as the parent entity and carries parallel 8(a) and federal contracting authority; the parent structure includes ten joint-venture subsidiaries across facility management, engineering, and program-support disciplines.
GSI Hawaii's customer base concentrates on military construction and facility support at Pacific installations. The Department of the Army Corps of Engineers accounts for 100% of the combined potential value across recent awards through two distinct offices: the Engineering and Support Center (two awards, $9 million combined potential value) and Engineering District Honolulu (two awards, $7.6 million). The Department of Transportation's Pipeline and Hazardous Material Safety Administration holds one $3.8 million award for environmental staffing support. The Department of the Navy's Naval Facilities Engineering Command rounds out the set. Representative work includes a $5.6 million firm fixed-price definitive contract from the Army Corps of Engineers Engineering and Support Center (awarded September 2025, ultimate completion March 2030) for TAMC-FTDTL-NHC medical facilities support services in Honolulu, a $3.358 million definitive contract from the same office (awarded July 2026, ultimate completion December 2030) for construction quality management at Triple Army Medical Center and Naval Health Clinic Joint Base Pearl Harbor, a $5.1 million definitive contract from the Army Corps of Engineers Engineering District Honolulu (awarded October 2023, modified January 2025) for window replacement at Fort Shafter Building 503A, and a $3.78 million definitive contract from PHMSA (awarded September 2025, ultimate completion September 2030) for Environmental Division staffing support in Washington, DC.
Activity is limited to six prime and sub awards across the past three years — one in 2023, three in 2025, and two in 2026 — with combined potential value of $20.3 million and $9.4 million obligated (46% of potential value). The recompete horizon carries significant exposure: four awards with ultimate completion dates in the next twenty-four months total $16.7 million in potential value, representing recompete opportunity for competitors and execution risk for the vendor. In its single identified sub-award role, GSI Hawaii delivers services to the University of Hawaii on a Marine Corps Base Hawaii water resiliency study sub-task (awarded January 2026). The vendor's capability mix spans facilities support services, commercial and institutional building construction, engineering services, and environmental consulting, with primary PSC concentration in professional support and program management. No parent vehicle (GWAC, IDIQ, or BPA) appears in the source; the vendor operates on definitive contracts and purchase orders issued directly by customer agencies.
