Diamond Project Co., LTD.

Diamond Project Co., LTD., a for-profit limited liability company headquartered in Yokohama, Japan, provides facilities maintenance, repair, and preventive maintenance services to U.S. Department of Defense installations in the Asia-Pacific region as a prime contractor on an unrestricted (full-and-open) competitive basis, with no SBA set-aside certifications. The company operates 100% as a prime (57 awards) with no subcontract footprint.

Diamond Project's federal customer base concentrates heavily within the Department of the Navy. The top five customer agencies account for 95% of awards, dominated by Navy Installations Command (29 awards, $10.5 million combined potential value), Naval Sea Systems Command (11 awards, $1.8 million), Naval Facilities Engineering Command (8 awards, $374 thousand), Bureau of Medicine and Surgery (3 awards, $1.4 million), and Department of the Air Force Pacific Air Forces (3 awards, $35.2 million). However, potential-value concentration diverges sharply from award count: Pacific Air Forces anchors the portfolio with a single $35.04 million blanket purchase agreement for kitchen hood and exhaust system inspections at Yokota Air Base and Tama Service Annex, while Navy Installations Command's higher volume translates to lower per-award values. Navy work clusters in two-to-three-month delivery orders under single-award indefinite-delivery contracts, whereas the PAF vehicle represents a five-year, multiple-award BPA.

Diamond Project holds four active single-award IDIQs with Navy agencies. Navy Installations Command awarded a $2.898 million IDIQ on February 26, 2026, for preventive maintenance and repair of water facilities circulation systems at Commander Fleet Activities Yokosuka through April 2031 (ceiling potential value $2,898,136.50), a $500 thousand IDIQ on August 1, 2025, for kitchen equipment maintenance and repair at Department of Defense Education Activity schools through July 2030, and a $315,754.97 IDIQ on December 1, 2024, for petroleum oil and lubricants tank and car-washing-system maintenance at Yokosuka through November 2029. Naval Facilities Engineering Command awarded a $315,754.97 single-award IDIQ for underground storage tank and car-washing-system maintenance. Diamond Project also holds a $35.04 million multiple-award blanket purchase agreement with Pacific Air Forces (award date February 29, 2024, completion September 2024 on initial period, extended task orders into 2025).

Recent concrete work typifies the portfolio: a $199,413.06 delivery order from Navy Installations Command (April 2026) for preventive maintenance of water circulation systems at Yokosuka through April 2027; a $122,022.84 firm fixed-price purchase order from Navy Installations Command (June 2025) for replacement of a fuel tank truck engine and parts at Yokosuka; a $120,117.50 firm fixed-price BPA call from Pacific Air Forces (July 2024) for kitchen hood and exhaust system inspections and cleaning at Yokota Air Base and Tama Service Annex through September 2025; a $105,631.54 delivery order from Naval Sea Systems Command (January 2026) for port security barrier repair and float-unit replacement at Truman Bay, Yokosuka; and a $106,804.09 delivery order from Naval Sea Systems Command (February 2024) for preventive maintenance and inspection of a pump test bench system through March 2025. Work scope includes kitchen equipment and hood maintenance, port security barrier systems, pump test benches, water and fuel systems, refrigeration units, medical gas systems, and janitorial/cleaning services.

Activity has remained modest and relatively stable—four to ten awards per year from 2022 through 2025—with only four awards (combined potential value $387 thousand) reaching ultimate completion within the next twenty-four months, suggesting limited near-term recompete exposure. The portfolio concentrates in NAICS 338399 (Commercial and Industrial Machinery and Equipment Repair and Maintenance) and Facilities Support Services, with PSC codes emphasizing maintenance of schools, industrial buildings, testing facilities, and non-building structures. All work is performed in Japan, primarily at Navy installations in Yokosuka and Air Force installations in the Tokyo area. Diamond Project has no federal vehicles of its own and competes exclusively as a task-order recipient under customer-held single-award or multiple-award IDIQs and BPAs, with no GSA Schedule or government-wide GWAC presence. The company entered the federal market in 2019 and has maintained continuous activity since, with total combined potential value of $49.4 million across the 57-award footprint; only $3.5 million (7%) has been obligated to date, indicating a substantial pipeline of option periods and task-order ceiling authority.
