Construction, Maintenance and Repair in Okinawa, Japan

The Department of the Army Corps of Engineers Engineering District Japan awarded a multiple-award Master IDIQ for construction, maintenance, and repair work at U.S. Government facilities throughout Okinawa, Japan on April 21, 2021, with ordering authority extending through April 20, 2028—approximately 21 months remaining. The vehicle carries a shared ceiling of $95 million across all awardees and is unrestricted (no set-aside).

Ordering velocity has declined sharply. The vehicle issued 12 task orders each in 2021 and 2022, dropped to 4 orders per year in 2023 and 2024, and has placed only 1 order year-to-date (August 2025). A total of 33 task orders have been awarded to date with combined potential value of $75.7 million, representing 100% obligation of the combined potential value against the $95 million ceiling. The most recent award was issued August 12, 2025 for HVAC installation at Torii Station valued at $5.2 million.

Scope spans design-build and design-bid-build delivery across the full breadth of construction, maintenance, renovation, repair, demolition, and environmental remediation (including asbestos, lead-based paint, mold, PCB, and site contamination). Recent orders exemplify the range: HVAC system replacement, roof design and repair, electrical and lighting infrastructure, retaining-wall and bridge rehabilitation, munitions facility repairs, transformer and chiller replacement, waterfront infrastructure, and environmental remediation. Task order values range from under $1 million to approximately $6.5 million, with durations typically 18 to 24 months from award.

Competition is concentrated among a small field of Japan-based and joint-venture primes. American Engineering Corporation leads with 12 orders valued at $35 million combined potential. Seikitokyu Kogyo-Yabu Doken JV holds 6 orders worth $19.4 million; Witco Industries LTD. 4 orders for $9.9 million; and Sumiju Yokosuka Kogyo Co., LTD. 2 orders totaling $6.5 million. These four firms account for approximately 85% of awarded orders and 99% of combined potential value. The remaining six primes, including Onaka Gumi Co., Ltd., capture a narrow margin.

Funding is concentrated almost entirely within the contracting agency: Department of the Army Corps of Engineers Engineering District Japan placed 32 orders for $74 million combined potential value; Finance placed 1 order for $1.7 million. All work is performed in Okinawa, Japan, primarily at Kadena Air Base, Camp Foster, Camp Kinser, Camp Schwab, and Camp Hansen.

Requirements may include, but are not limited to, providing zero to 100 percent design effort, reproduction, labor, transportation, materials, equipment, and supervision necessary to accomplish various maintenance, repairs, alternations, construction, demolition, and associated incidental environmental work (including but not limited to asbestos, lead-based paint, mold, PCBs, site contamination, etc.) to U.S. Government facilities in Okinawa, Japan.
