Architect-Engineer Services to Support Military Engineering Design and Planning Services Various Locations - Japan

The Department of the Army Corps of Engineers Engineering District Japan (ENDIST Japan) established a Master IDIQ on September 6, 2019, supporting US Military Construction, Sustainment, Restoration, and Modernization (SRM), and Host Nation Construction programs at military installations across Japan, with ordering authority expiring September 5, 2026—approximately one month remaining. The vehicle carries a combined potential value of $150.9 million and is unrestricted, open to all contractors.

The IDIQ has obligated $140.3 million of its ceiling (93%), signaling mature execution and limited remaining capacity for new work. Ordering activity has declined sharply: 31 orders in 2022 represented peak annual volume, but only 18 orders were placed in 2024 and 2 through January 2025, indicating the vehicle is approaching the end of its productive ordering window. Of 118 task orders awarded since March 2020, the most recent was issued January 24, 2025.

Task orders span design, construction phase support, and engineering services across base-wide infrastructure modernization: housing renovation (Kishaba and Courtney Towers at Camp Foster and Kadena, family housing at Yokota and Camp Zama), airfield and aircraft maintenance facilities (hangar renovations, corrosion control centers, aircraft rescue operations), utility upgrades (electrical, water, sewer, telecommunications), fuel storage and distribution systems, and mission-critical facilities including secure working areas and command centers. Typical order values range from under $200 thousand for surveys and studies to $3–9 million for multi-phase design-build packages. The single largest obligation on record is $12.4 million for F-35 simulator and aircraft maintenance hangar work.

Competition is moderately concentrated among five firms capturing 41 percent of orders by count: Ahl-Gae JV LLC, AECOM Technical Services Inc., Design Partners Incorporated, Insynergy Engineering Inc., and Stanley-Setiadi Joint Venture hold the most task orders. By potential value, the top five (Ssfm International Inc., AECOM, Louis Berger Kyowa JV, Jacobs Government Services Co, and Design Partners) account for 51 percent of combined value, with no single prime dominating. Sixteen distinct primes have received awards, suggesting a competitive market with room for new entrants willing to support Japan-based operations. All 118 orders are designated No Set-Aside Used, reflecting open competition.

Customer concentration is absolute: all task orders fund ENDIST Japan programs. Work is performed throughout Japan, concentrated at Kadena Air Base and Okinawa installations (Camp Foster, Camp Courtney, Camp Hansen, Torii Station, Camp Kinser, MCAS Futenma, MCAS Iwakuni), plus Yokota Air Base and other Honshu locations (Yokohama, Atsugi, Sagami General Depot, Camp Zama, Misawa, Kure). Pursuit of this vehicle requires Japan operational capability and experience with DOD military construction scope in a host-nation environment.

This IDIQ supports US Military Construction (MILCON), Sustainment, Restoration, & Modernization (SRM), Host Nation (HN) Construction, and Foreign Military Sales (FMS) programs for Department of Defense service components and support agencies within Japan. Projects contemplated under this IDIQ include those that would typically support the operations and functions of US military installations in Japan, including, but not limited to: administrative; training support; mission and operations; lodging; unaccompanied housing; family housing; educational; religious; sports; health and wellness; dining; storage; telecommunications; secure data operations; medical and dental; aircraft operations and maintenance; airfield runways and pavements; roadways; fuel storage and distribution; ship and waterfront operations; piers and wharfs, dredging; munitions storage; base wide utility infrastructure to include communication, power, water, gas, and sewer; and environmental mitigation.
