About the company
Nippon Koei Co., LTD., a foreign-owned Japanese construction consulting firm, delivers architect-engineer and civil-structural engineering services to the U.S. Navy and Marine Corps as a prime contractor exclusively, with no subcontract footprint across 144 federal awards totaling $44 million in combined potential value. The firm operates on a full-and-open posture — no set-aside awards — and specializes in design, geotechnical investigation, facilities assessment, and infrastructure repair at U.S. military installations throughout Japan.
Nippon Koei is a subsidiary of Integrated Design & Engineering Holdings Co., LTD., also based in Tokyo. The company is registered with the System for Award Management since November 2015 and has held a $10 million single-award architect-engineer IDIQ with Naval Facilities Engineering Command since November 1, 2020, running through October 31, 2025. Recent representative work includes a $591,042 delivery order from Naval Facilities Engineering Command for a four-slip wet berth upgrade at Commander Fleet Activities Sasebo (October 2025, ultimate completion November 2027); a $1,052,088 delivery order from the Marine Corps for civil structural engineering and geotechnical investigation at Marine Corps Air Station Iwakuni (September 2023, completed August 2025); a $645,596 delivery order from Navy Installations Command for ground study services at Commander Fleet Activities Yokosuka (July 2023, completed January 2025); and a $638,628 delivery order for pump house repair and post-construction award services at Destroyer Squadrons 4 and 5 in Japan (September 2023, ultimate completion August 2027). Work is performed in Japan at Navy and Marine Corps locations, including Sasebo, Yokosuka, Okinawa, Iwakuni, and Kadena Air Base.
Customer concentration is heavily weighted to the Navy. Naval Facilities Engineering Command dominates by both award count and dollars — 78 awards carrying $34.7 million combined potential value (79% of the portfolio) — followed at significant distance by Navy Installations Command (25 awards, $5.4 million) and the Marine Corps (18 awards, $3.6 million). The top three customers account for 97% of awards and the full combined potential value. Across five Navy-related IDIQs, Nippon Koei places between 15 and 37 task orders per vehicle; the largest by task-order volume is Indefinite Delivery Contract N4008408D0053 (37 task orders, $3.8 million), followed by N6283602D0001 (25 task orders) and N4008415D0022 (19 task orders, $5.6 million). The portfolio shows substantial historical depth — the firm's first award in source data dates to 1989 — but recent activity is sparse; awards per year averaged only 2.8 over the past five years (2020–2025), with two awards placed in 2025. Only four awards face completion in the next twenty-four months, carrying combined potential value of $2.3 million, limiting near-term recompete exposure. The capability portfolio clusters tightly: 80 awards fall under Architectural Services NAICS, 53 under Engineering Services, with industrial buildings and architect-engineer general services dominating the PSC breakdown, including 8 marine engineering line items reflecting the firm's berth and dock specialization.
