Amentum Design And Facility Management

Amentum Design And Facility Management, a division of Pacific Architects & Engineers (PAE), a subsidiary of Amentum Services, Inc., delivers facilities maintenance, construction, janitorial services, and architect-engineer design support to federal military and diplomatic installations in Japan as a prime contractor (93% of recent awards) competing under full-and-open procurement without set-aside designations. Headquartered in Tokyo, Japan, the firm operates as a for-profit entity registered in SAM.gov since 2009, executing a high-volume, geographically concentrated portfolio focused on overseas installations where it holds established relationships across Navy, State Department, Army Corps of Engineers, Air Force, and Marine Corps customer bases.

Customer concentration is pronounced and regionally locked. The top five funding agencies account for 80% of recent awards by count but the rankings shift materially by dollar value. Navy Installations Command dominates both volume (82 awards, $51.3 million combined potential value) and is matched in dollar terms by the Army Corps of Engineers Japan District (11 awards, $51.8 million), reflecting a high-value architect-engineer portfolio for host-nation construction program support. The State Department's Bureau of East Asian and Pacific Affairs (63 awards, $19.9 million) and Bureau of Overseas Building Operations (79 awards, $15.7 million) round out the top tier, with the Marine Corps (12 awards, $30.7 million) appearing only in the dollar ranking, indicating fewer but larger contracts. All customers are civilian or defense agencies operating in Japan; the vendor has no domestic U.S. footprint visible in recent awards.

Amentum Design and Facility Management's capabilities center on on-site facilities maintenance, janitorial services, building systems repair, vertical transportation (elevator and escalator) preventive maintenance, window and railing replacement, HVAC work, and architect-engineer criteria package development for military construction projects. Representative prime work includes a $1.285 million Navy delivery order for recurring facility maintenance and operations support (March 2026, ultimate completion March 2027), a $1,021,370.91 Navy delivery order for preventive maintenance of vertical transportation equipment at Commander Fleet Activities Kanto Plain (March 2025–March 2026), a $577,319.20 State Department roofing replacement contract for Marine Security Guard residences at the U.S. Embassy Tokyo (September 2024–July 2025), a $5 million single-award IDIQ from the Bureau of East Asian and Pacific Affairs for janitorial services at the U.S. Embassy Tokyo (September 2025–September 2027), and a $49 million Army Corps of Engineers IDIQ for architect-engineer services supporting host-nation construction programs across Japan (September 2022–September 2027). Secondary work includes electrical and drop-ceiling installation in diplomatic housing units, ground-floor scaffolding and railing safety upgrades at the Mitsui Housing Compound in Tokyo, and specialized equipment repairs (fuel pumps, inverter units, control boards, suspension ropes for vertical transportation systems).

Activity has grown year over year from 26 awards in 2022 to a peak of 43 awards in 2024, with 31 awards in 2025 and 15 awards in the first nine months of 2026 (through September 30). Fourteen awards with combined potential value of $4.1 million face ultimate completion inside the next twenty-four months and thus represent recompete exposure. The vendor operates primarily as a prime contractor, holding nine active IDIQs: a $16.4 million Navy Installations Command single-award indefinite delivery contract for fire protection and intrusion detection system maintenance at Commander Fleet Activities Yokosuka (March 2026–March 2031); a $10.1 million Navy single-award IDIQ for vertical transportation equipment preventive maintenance and service orders at the Kanto Plain facility (March 2025–March 2032); a $5 million Bureau of East Asian and Pacific Affairs single-award IDIQ for janitorial services at the Tokyo Embassy (September 2025–September 2027); a $4.5 million State Department Bureau of Overseas Building Operations single-award IDIQ for window sash and balcony fall protection replacement at the Mitsui Housing Compound (September 2022–September 2027); a $2.2 million Navy single-award IDIQ for jet engine test cell and aircraft maintenance facility support at Naval Air Facility Atsugi (March 2024–February 2029); a $702 thousand Bureau of East Asian and Pacific Affairs single-award IDIQ for building maintenance services in Japan (July 2023–June 2027); a $716 thousand Bureau of East Asian and Pacific Affairs single-award IDIQ for building maintenance services in Sapporo (June 2022–May 2027); a $700 thousand Pacific Region Defense Department single-award IDIQ for inspection, maintenance, and repair of underground storage tanks at three Japan facilities (July 2025–June 2030); and a $49 million Army Corps of Engineers multiple-award IDIQ for architect-engineer services supporting host-nation construction programs across Japan (September 2022–September 2027).

Subcontractor footprint reveals a sub-heavy posture relative to the vendor's prime-contract dominance. Named subcontractors include KBR Services, LLC (recurring across 2023–2025 for Base Operations Support – Japan local national labor and ad-hoc services); Johnson Controls Building Automation Systems, LLC (fire damper replacements, April 2025); and RLF And Sherlock Smith And Adams JV (architect-engineer design task order support, October 2024). SCI-reportable invoiced revenue totaled $666 thousand across FY2022–FY2025 (a three-year window with FY2023 and FY2024 mostly absent from reporting), delivered by 7.1 FTEs in FY2022 and 0.4 FTEs in FY2025, at a median government-paid hourly rate of $26.78/hr. This SCI subset represents only facilities-support and custodial labor on specific service contracts above the $150,000 threshold and excludes goods, construction definitive contracts, and the bulk of the vendor's overseas facilities footprint.

The vendor's facility maintenance and janitorial service work dominates by category count (81 facilities support services awards, 36 janitorial services awards, 26 remediation awards, 22 finish carpentry awards, 21 HVAC awards), with facilities operations support (54 awards), ship construction and repair facility maintenance (33 awards), and family housing facility maintenance (32 awards) comprising the bulk of PSC coding. All work is performed in Japan, with primary administrative and operational oversight centered at the Tokyo headquarters. The near-total absence of domestic U.S. awards, combined with the firm's legal establishment and personnel presence in Japan and its history of SOFA-program compliance, positions it as the dominant facilities contractor for U.S. government installations throughout the Japanese archipelago.
