American Engineering Corporation

American Engineering Corporation, a foreign-owned for-profit construction and facilities management company headquartered in Okinawa, Japan, operates as a prime contractor (100% of recent awards) delivering design-build and design-bid-build construction, facility maintenance, HVAC systems installation and repair, roofing and exterior painting, electrical infrastructure upgrades, and comprehensive infrastructure support across U.S. Department of Defense installations throughout Japan and the Pacific region. The company is not a certified small business and competes full-and-open across all federal awards with no set-aside designations.

American Engineering Corporation's customer concentration is extreme and geographic-mission driven. The top five agencies account for 72% of awards by count and 93% of combined potential value. Pacific Air Forces leads by dollar magnitude with 753 awards worth $6.82 billion in combined potential value, followed by the United States Marine Corps with 1,773 awards worth $3.18 billion. Department of the Navy Installations Command (207 awards, $1.01 billion), Naval Facilities Engineering Command (308 awards, $534.3 million), and Department of Defense Education Activity (449 awards, $521.8 million) round out the top five. The overwhelming concentration reflects the vendor's entrenched position as the primary infrastructure support provider for U.S. military installations in Japan—the company has been registered in the System for Award Management since January 2002 and maintains sustained operational presence in Okinawa serving multiple branches and commands.

Capability portfolio centers on concrete military facility operations. Representative work includes a $32.4 million design-build repair of Stearley Heights Elementary (Buildings B2261, 2279, 2285) into office space at Pacific Air Forces installations (April 2026 award), a $21.4 million corrosion repair services contract with the Marine Corps at Camp Kinser handling inspection, disassembly, cleaning, body repair, surface preparation, coating, and reassembly of vehicles and equipment (August 2025 award), and a $17.3 million firm fixed-price delivery order for repair of Building 608 (Project Management Office and Law Center facilities) at Marine Corps Air Station Iwakuni (September 2025 award). Recurring work includes HVAC system replacements, roofing and exterior painting (thousands of smaller delivery orders across installations), fire protection systems maintenance, electrical infrastructure upgrades, elevator and vertical transportation equipment repair, facility refurbishment, and site-level construction management supporting military base operations.

Vehicle position is dominant across legacy and newly awarded IDIQs. American Engineering Corporation holds a $995 million multiple-award Indefinite-Delivery/Indefinite-Quantity contract with Pacific Air Forces for design-build and design-bid-build construction services throughout Japan (awarded September 2025, extending through September 2028); a $250 million multiple-award MACC with the Marine Corps for small-magnitude design-bid-build construction at Marine Corps Air Station Iwakuni (awarded August 2024, extending through August 2029); a $250 million multiple-award MACC for small-magnitude construction at Marine Corps Base Camp Butler and Commander Fleet Activities Okinawa (awarded August 2024, extending through June 2029); a $32.45 million single-award IDIQ for roofing and exterior painting services at Marine Corps Air Station Iwakuni (awarded September 2024, extending through September 2031); a $3.15 million single-award IDIQ for fire protection systems maintenance at Marine Corps Base Camp Butler and U.S. Naval Hospital (awarded July 2024, extending through August 2029); and smaller BPAs and construction vehicles with the Navy and Air Force. Top parent vehicles by task order count are Indefinite Delivery Contract FA527004D0007 (465 task orders, $59.8 million), Indefinite Delivery Contract N4008407D2009 (317 task orders, $52.8 million), and the Kadena Multiple Award Construction Contract (187 task orders, $443.8 million). American Engineering Corporation places work almost exclusively through these IDIQs and MACCs; competitive bidding occurs at the task-order level within each vehicle's indefinite-quantity framework.

Activity has contracted sharply after sustained volume. Awards per year show 198 in 2022, 293 in 2023, 219 in 2024, then declining to 92 in 2025 and only 34 as of May 2026. This decline reflects maturation of the vendor's portfolio under long-standing IDIQs and MACCs and the shift from award-count to task-order-based ordering under existing vehicles. Combined potential value across the entire 5,360-award portfolio is $13.02 billion; combined dollars obligated to date stand at $2.19 billion (17% of potential). Ninety-four awards face ultimate completion within the next twenty-four months with combined potential value of $321.8 million—significant recompete exposure, though most underlying IDIQs and MACCs carry multi-year remaining performance periods that position American Engineering Corporation as the incumbent for continued task order issuance at these vehicles' installations.

Service Contract Inventory data is sparse and uninformative. SCI captures only three records (two prime, one sub) across FY2022–FY2024, with zero invoiced revenue reported in prime records and zero FTE equivalents in FY2022–FY2023. One sub-record shows 6.3 FTEs in FY2024 under an IAP World Services prime. This minimal SCI footprint reflects the nature of American Engineering Corporation's federal work: the vast majority of the vendor's $13 billion portfolio consists of construction contracts and facility maintenance delivery orders (which SCI captures selectively and only above the $150,000 threshold), goods procurements, and site-level labor embedded in larger MACC and IDIQ task orders that may not trigger separate SCI reporting as discrete service contracts. SCI does not represent the vendor's true federal service-labor scale or revenue.

Teaming pattern is minimal. American Engineering Corporation operates almost exclusively as a prime contractor. The sub-award footprint is negligible: 24 sub-awards identified across the entire portfolio (0.4% of total awards), including work as a named subcontractor to Siemens Government Technologies (DISA EWISS III surveillance maintenance at Fussa, Japan, January 2026), IAP World Services (satellite communications sustainment and site prep at Futura and Misawa, November–October 2025), CACI Inc. (Enterprise IT-as-a-Service base infrastructure modernization at Kadena, Misawa, Yokota, Kunsan, and Osan, October 2025), Xator LLC (Kadena intrusion detection system upgrade, September 2025), and Mantech TSG-2 Joint Venture (Marine Corps Force Design and Modernization construction, April 2025). Across SCI, average sub-hours share is 0%, confirming that American Engineering Corporation builds its own delivery teams and does not rely on significant subcontractor labor on its prime contracts. The vendor does not function as a major feeder subcontractor to larger defense primes; subcontracting relationships are episodic and secondary to its core role as the primary infrastructure prime for Pacific military installations.

Background context from the source: American Engineering Corporation is described as a foreign-owned construction and facilities management company bringing extensive experience supporting U.S. military infrastructure across Japan and the Pacific region. The company has been registered in SAM.gov since January 2002 and operates from headquarters in Okinawa, with established local presence, labor resources, and supplier relationships that make it the default incumbent for recurring construction and maintenance work at installations where it has held multiple prior contracts. The contractor's competitive position rests on location, continuity, installed knowledge of facility conditions at multiple bases, and long-standing contractual relationships with Pacific Air Forces, the Marine Corps, and the Navy—not on specialized technical differentiation or scale. American Engineering Corporation does not compete in full-and-open civilian federal construction markets; its entire federal portfolio is military installation support in Japan.
