About the company
Gilbane Japan GK Federal Division, a joint venture between Gilbane, Inc. and Exyte operating as a limited liability company registered in Tokyo, is a design-build and design-bid-build military construction contractor working exclusively on U.S. military installations throughout Japan as a prime contractor (100% of recent awards) under no socioeconomic set-asides. The division competes in full-and-open unrestricted procurements requiring contractors physically located and licensed in Japan, reflecting the Status of Forces Agreement acquisition framework that governs U.S. military construction overseas.
Gilbane Japan GK's capability portfolio centers on commercial and institutional military building construction (NAICS 236220, PSC Y1BZ and related codes) spanning family housing renovation, airfield facilities, specialized military structures, and educational infrastructure. Representative work includes a $130.3 million design-build contract awarded July 2022 by ENDIST Japan to replace Kinnick High School at Commander Fleet Activities Yokosuka (completion October 2026); a $103 million firm-fixed-price contract awarded October 2023 for construction of a C-130J corrosion control hangar at Yokota Air Base (completion February 2027); a $53.1 million design-build roof repair contract awarded December 2025 by Pacific Air Forces for the 353rd Special Operations Wing operations facility at an unspecified Japan location (completion December 2028); and a $36.75 million definitive contract awarded May 2026 by the Army Corps of Engineers Japan District for Yokota Air Base family housing improvements Phase 2 (completion November 2028).
Customer concentration is heavily weighted toward the Department of the Air Force Pacific Air Forces, which anchors the portfolio with five awards totaling $2.04 billion in combined potential value (59% of all dollars), including the $995 million Okinawa Multiple Award Construction Contract IDIQ awarded September 2025. The United States Marine Corps accounts for two awards worth $625 million combined. The Army Corps of Engineers Japan District leads by award count with eleven contracts totaling $552.7 million, while the Navy Installations Command holds two awards worth $250 million. All four customer agencies are military-focused with Japan-region footprints.
Gilbane Japan GK holds position on five named multiple-award construction contracts: the $995 million Okinawa MACC (Pacific Air Forces, September 2025–September 2028), a $250 million Design Build MACC at Atsugi (Navy Installations Command, through June 2027), and three additional regional MACCs carrying nominal minimum-guarantee task orders. Task-order activity against parent vehicles remains minimal; the majority of the pipeline consists of definitive contracts directly awarded rather than delivery orders drawn from IDIQs.
Activity was volatile over the past five years, ranging from six awards in 2021 to one in 2026; the source reflects a recent two-year decline (2023–2024) followed by a return to four awards in 2025 and one award in mid-2026. Five awards with combined potential value of $179.2 million face ultimate completion within the next twenty-four months, creating near-term recompete exposure across family housing, facility repair, and airfield projects at Yokota Air Base and other Japan-area installations. Combined potential value across all twenty awards totals $3.47 billion, against which $506.2 million (15%) has been obligated to date. Gilbane Japan GK operates as a subsidiary of Gilbane Federal, a parent corporate entity based in Concord, California.
