Kanto Japan Plains Operation MACC

The Department of the Navy Installations Command awarded this Master IDIQ for design-build and design-bid-build construction services in the Kanto Plains operational area of Japan on June 30, 2023, with a combined ceiling of $250 million and ordering authority extending through June 29, 2028. Approximately 22 months of ordering authority remain. The solicitation contemplated approximately eight awards; eight distinct primes have been awarded to date.

All 24 task orders are unrestricted, competitive procurements. Work encompasses office renovation, building demolition, equipment repair and replacement, piping systems, electrical and mechanical work, road pavement, fencing, roofing, painting, site work, and removal and disposal of lead-based paint and asbestos-containing material across U.S. military facilities including U.S. Fleet Activities Yokosuka, U.S. Naval Air Facility Atsugi, and Marine Corps Combined Arms Training Center Camp Fuji, with task-order scope and location specified individually. Recent task orders include pump house repairs at Yokosuka, replacement of air handling and chiller units, caisson dry dock overhaul, slope stabilization, and housing area storage shed replacement.

Combined task-order potential value stands at $108.6 million, with $108.2 million obligated (100% of combined potential). Five primes dominate: American Engineering Corporation leads by potential value at $33.4 million across two orders; Nikkai Corporation holds $24.4 million across five orders; Sumiju Yokosuka Kogyo Co., LTD. holds $24.2 million across six orders; Nippo Corporation holds $9.7 million across two orders; and Nihon Meccs Co., Ltd. holds $8.6 million across four orders. These five firms capture 92% of combined potential value. All orders fund Navy Installations Command programs. Task orders range from demonstration and minimum-guarantee orders at nominal value to substantial projects: the largest, "RM18-2232 REPAIR UH BLDG 1530," obligated $33.4 million. Ordering velocity averaged 8 orders in 2023, 10 in 2024, and 6 through August 2025, suggesting moderating activity in 2025.

The proposed scope of work for this IDIQ MACC may include, but is not limited to office renovation, building demolition, built-in equipment repair/replacement, piping repair/replacement, pipe lagging, electrical work, mechanical work, road pavement, fencing, roofing, painting, site work, removal, and disposal of lead-based paint and asbestos containing material, welding, and masonry in the Kanto Plains operational area.
