About this vehicle

The Naval Facilities Engineering Command (NAVFAC) awarded this multiple-award master IDIQ on January 6, 2021, for firm-fixed-price design-bid-build and design-build construction services in Guam and other Pacific areas. The ordering period closed on January 5, 2026, so this vehicle is no longer accepting new task orders.

The vehicle funded projects primarily through Government of Japan (GOJ) contributions, with GOJ officials participating as observers in the contracting and design-construction process. NAVFAC Pacific served as the Department of Defense's Executive Agent for Construction on Guam. The shared ceiling was $990 million across all awarded primes.

Over its five-year active life, 21 task orders were awarded with combined potential value of $898.3 million and $834.8 million obligated (93% of potential value). Activity was front-loaded: nine orders in 2021, then three in 2022, four in 2023, four in 2024, and one in 2025. Core Tech-Hdcc-Kajima LLC led in dollar value with $379.5 million across five orders, followed by Hensel Phelps-Shimizu JV at $208.2 million across four orders and Black Construction-Tutor Perini JV at $156.4 million across five orders. These three firms captured roughly 70% of combined potential value; Caddell-Nan A Joint Venture, Aptim-Tokyu Construction JV, and two smaller primes shared the remainder. Task orders were unrestricted—no set-aside designations applied.

All orders funded NAVFAC priorities. Recent task orders (awards in 2023–2025) ranged from $25.6 million to $116.5 million and targeted facilities including barracks, education centers, corrosion control infrastructure, utilities, motor pools, and embarkation facilities at Naval Support Activity Guam and Marine Corps Base Guam. Typical durations extended 18–24 months from award. The most recent award, December 15, 2025, to Core Tech-Hdcc-Kajima LLC, was for outdoor playing fields and potable waterline interconnect work with a ceiling of $36.4 million and completion deadline of October 9, 2028.
