Sankyo Denki Ohna Denken JV

Sankyo Denki Ohna Denken JV, a for-profit corporate entity based in Okinawa, Japan, delivers design-build and construction services to the Department of Defense as a prime contractor on full-and-open (no set-aside) delivery orders and indefinite-delivery contracts focused on military facility repair, renovation, and infrastructure modernization at U.S. installations in Japan.

The vendor operates exclusively as a prime contractor — all 54 awards in the source are prime positions with zero subcontract work. Sankyo Denki Ohna Denken JV holds a $995 million ceiling on the Okinawa Multiple Award Construction Contract 2025-2028, a multiple-award IDIQ awarded by Pacific Air Forces in September 2025 running through September 2028. Under this vehicle, the vendor has received three delivery orders to date, including a $7.3 million ceiling order in June 2026 for repair and renovation of Wakaba CDC at Kadena Air Base, Okinawa, and a $1.955 million order in May 2026 for facility updates to Building 3537 at Kadena to accommodate the Joint Air Operation Command within the 353rd Special Operations Wing. Both orders are priced on a firm fixed-price basis with completion dates in 2027–2028. The vendor's capability portfolio centers on electrical systems, HVAC systems, lighting systems, and general building repair and alteration across NAICS codes for specialty trade contracting (33 awards) and commercial and institutional building construction (19 awards).

Customer concentration is heavily skewed to Pacific Air Forces. The Department of the Air Force Pacific Air Forces anchors the portfolio with 12 awards carrying $1.01 billion in combined potential value, while the United States Marine Corps follows with 37 awards totaling $252 million. Together, these two customers represent 100% of awards in the source. The Marine Corps volume reflects prior-year work under expired NAVFAC Okinawa construction vehicles (14 task orders, $15.7 million combined under the 2011–2014 NAVFAC Okinawa Japan Construction IDIQ, and 14 task orders, $30.5 million under the 2016–2021 NAVFAC Okinawa Construction IDIQ). Activity volume has been low in recent years — one or two awards annually in 2018–2020, two awards in 2025, and two in 2026 — with most of the historical volume concentrated between 2011 and 2017. Only two awards (combined potential value $9.3 million) reach completion within the next twenty-four months, creating minimal recompete pressure in the near term. However, the new $995 million MACC vehicle with Pacific Air Forces represents a significant runway for task-order volume through 2028, provided the government places orders against it.
