About Ohishi Construction CO. LTD
Ohishi Construction CO. LTD, a for-profit Japanese construction company headquartered in Sasebo, Nagasaki, delivers facility maintenance, dredging, pier and harbor repairs, asbestos abatement, building renovation, and general contracting services to the U.S. Navy at installations throughout Japan as a prime contractor under multiple indefinite delivery contracts and delivery orders, with no subcontracting footprint.
The vendor operates exclusively on full-and-open federal contracts carrying no set-aside designations. Ohishi has registered in SAM.gov since 2005 and competes for work across a portfolio of Navy IDIQs and a multiple-award construction contract, placing 162 prime awards with a combined potential value of $553.3 million since the early 2000s. The company's customer concentration is extreme and singular: the Department of the Navy Installations Command anchors 68 awards worth $492.7 million (89% of all combined potential value), followed distantly by Naval Facilities Engineering Command (23 awards, $32.6 million), Department of the Navy (47 awards, $9.8 million), Bureau of Medicine and Surgery (2 awards, $9.7 million), and United States Pacific Fleet Forces (15 awards, $7.4 million). These five Navy components together account for 96% of all awards and 100% of combined potential value.
Ohishi's work sits on five primary vehicles. The largest is Indefinite Delivery Contract N6283601D6525 (57 task orders, $9.8 million combined potential value), followed by IDC N4008409D6508 (27 task orders, $33.1 million), IDC N4008405D6563 (12 task orders, $2.1 million), IDC N4008417D6504 (7 task orders, $20.5 million), and the Commander Fleet Activities Sasebo MACC 2020-2025 (6 task orders, $9.1 million). Recent headline awards include a $21.4 million definitive contract for maintenance dredging at U.S. Fleet Activities Sasebo (Navy Installations Command, awarded July 29, 2025, performance through May 31, 2027), a $5.4 million delivery order for battery maintenance facility access ladders under the Sasebo MACC (US Pacific Fleet Forces, awarded January 21, 2025), a $1.9 million delivery order for dog kennel refurbishment and isolation kennel construction at Sasebo Ammo Supply Point (Navy Installations Command, awarded March 9, 2026, ultimate completion February 24, 2027), and a $1.9 million delivery order for launch and recovery apron work at Yokose (US Pacific Fleet Forces, awarded August 14, 2025).
Award activity is sparse and episodic: two awards in 2021, two in 2023, three in 2024, three in 2025, and one in 2026. Recompete exposure in the next twenty-four months is concentrated: two awards (combined potential value $23.4 million) face ultimate completion dates within that window. Ohishi's capability footprint is construction-heavy, with top NAICS classifications under Other Foundation, Structure, and Building Exterior Contractors (41 awards), Commercial and Institutional Building Construction (15 awards), and Structural Steel and Precast Concrete Contractors (13 awards). Primary PSC categories align with building and facility maintenance — Miscellaneous Prefabricated Structures and Maintenance-Repair-Alteration of Miscellaneous Buildings (34 awards each), Maintenance-Repair-Alteration of Maintenance Buildings (12 awards), and Repair or Alteration of Office Buildings (7 awards). Work is performed entirely in Japan at U.S. Navy installations with administrative oversight by Navy Installations Command.
