Dan Engineering, Y.k.

Dan Engineering, Y.k., a Japan-based for-profit construction and facilities maintenance contractor headquartered in Wakabacho, Sasebo, Nagasaki Prefecture, operates exclusively as a prime contractor on Navy Installations Command delivery orders and indefinite-delivery vehicles, competing on an unrestricted basis without small business set-aside designation. The company has held a System for Award Management registration since November 2005 and specializes in architectural, mechanical, electrical, and civil works supporting U.S. Navy shore-based and waterfront facilities throughout Japan.

Dan Engineering's customer base is heavily concentrated with the Department of the Navy. The Department of the Navy Installations Command accounts for 126 awards (67% of the portfolio) with $128.1 million in combined potential value — 98% of the vendor's total potential value across all 187 awards. The Department of the Navy Naval Facilities Engineering Command represents the second-largest customer with 30 awards and $1.4 million, while the Department of Defense Education Activity, Department of the Navy Naval Sea Systems Command, and Defense Logistics Agency Land and Maritime collectively account for less than 1% of dollars. This extreme concentration reflects Dan Engineering's role as a specialized regional contractor for Navy facility projects in Japan.

Dan Engineering places task orders under a portfolio of Navy Installations Command indefinite-delivery vehicles. The company holds a single-award IDC (N4008424D6300) valued at $1.24 million through April 15, 2029, focused on hangar door system maintenance and repair at the Yokose Landing Craft Air Cushion Facility in Sasebo. The company also holds a $30 million multiple-award Mini-MACC (N4008424D6502) through March 6, 2029, covering architectural, mechanical, electrical, and civil works across Navy installations in Japan, with task order values ranging from approximately $20,000 to $2 million. Recent representative work includes a $478,591 delivery order (March 2026) for paving and painting of Building 5121, a $535,228 order (August 2025) for CO2 fire extinguishing system repair at Akasaki POL Depot, and a $860,937 delivery order (October 2023) for mezzanine deck demolition in Buildings 304 and 305. The company's scope spans facility repair, construction, maintenance, equipment installation, restoration, modernization, and demolition.

Activity has been variable in recent years — one award in 2022, two in 2023, five in 2024, three in 2025, and two in 2026 — with only two awards (combined potential value $612 thousand) maturing within the next twenty-four months. The primary NAICS categories are All Other Specialty Trade Contractors (60 awards), Electric Bulk Power Transmission and Control (34 awards), and Other Foundation, Structure, and Building Exterior Contractors (33 awards), with PSC codes concentrated in facility maintenance and repair (Maint-Rep-Alt/Misc Bldgs: 31 awards). All work is performed in Japan under firm fixed-price terms, and orders exceeding $150,000 require performance bonds. Combined dollars obligated stand at $13.1 million against $130.7 million in combined potential value — a 10% obligation rate reflecting the early-stage nature of many task orders on the multi-year IDVs.
