AECOM + Tetra TECH Joint Venture

AECOM + Tetra TECH Joint Venture, a strategic partnership between two major global engineering and infrastructure consulting firms operating as a child entity under parent company AECOM, serves as a prime contractor delivering architectural, engineering design, and program management services exclusively for the U.S. Department of Defense's ballistic missile defense infrastructure initiatives. The joint venture competes on full-and-open federal contracts with no set-aside designations across a focused customer base anchored by the Army Corps of Engineers and the Missile Defense Agency.

The joint venture's capability footprint centers on design, engineering, and program management for missile defense facilities — including missile control buildings, power plants, communications facilities, industrial workshops, administration buildings, and associated infrastructure systems such as roads and utilities. Recent representative work includes a $28.4 million design-build request for proposal development for a utility corridor at Francis E. Warren Air Force Base, Wyoming (awarded July 2025 by the Army Corps of Engineers Engineering District Omaha under the primary $48 million Ballistic Missile Defense Program Architectural & Engineering Services IDIQ); an $8.6 million Terminal High Altitude Area Defense (THAAD) design-during-construction delivery order for the Army Corps of Engineers (awarded December 2025); and a $9.2 million architectural and engineering design task order for Site 7 in Saudi Arabia (awarded January 2024 by the Army Corps of Engineers Engineering District Middle East).

Customer concentration is extremely narrow and heavily weighted toward Army Corps of Engineers organizational units. The top five customers account for 87% of recent awards, led by the Army Corps of Engineers Engineering Support Center Huntsville (15 awards, $808.1 million combined potential value), the Army Corps of Engineers Engineering District Middle East (19 awards, $161.9 million), the Army Corps of Engineers Engineering District Alaska (19 awards, $16.4 million), the Army European Command (13 awards, $113 million), and the DOD Missile Defense Agency (5 awards, $3.4 million). The divergence between volume and dollar rankings reflects a strategic concentration: Engineering Support Center Huntsville dominates on potential value while the two regional engineering districts (Middle East and Alaska) anchor the award count through numerous smaller task orders under the same master IDIQ vehicles.

The joint venture holds two primary IDIQ vehicles. A $400 million multiple-award Indefinite Delivery Contract was awarded on January 20, 2026, by the Army Corps of Engineers Engineering Support Center Huntsville, running through January 19, 2033, procuring the full spectrum of facility engineering and architectural services for the Ballistic Missile Defense System Mandatory Center of Expertise. A $48 million multiple-award IDIQ awarded April 17, 2025 (also by Engineering Support Center Huntsville, with completion October 17, 2030) serves as the primary vehicle for current task orders; 14 task orders totaling $67 million in combined potential value have been issued against it. Additional parent vehicles include Indefinite Delivery Contract W912ER20D0001 (18 task orders, $71.9 million) and W912GB10D0027 (18 task orders, $38.9 million), both supporting regional engineering district work across Alaska and overseas locations.

Place of performance spans multiple domestic military installations and worldwide locations — administrative oversight at the Engineering Support Center Huntsville with operational work at Fort Greely and Francis E. Warren Air Force Base (Alaska and Wyoming), domestic locations in Massachusetts and Hawaii, and sustained overseas presence in Saudi Arabia. The $1.21 billion combined potential value across 82 prime awards reflects a backlog concentrated in design and engineering services (79 awards under Engineering Services NAICS), with approximately $207.2 million obligated to date. Four awards totaling $20 million in combined potential value face ultimate completion within the next twenty-four months, presenting modest recompete exposure. The joint venture operates exclusively as a prime contractor — zero sub-awards are recorded in the source data — positioning it as a direct competitor on Army Corps of Engineers and Missile Defense Agency engineering work rather than as a teaming sub.
