About the company
Tetra Tech Inc. – EMI Division, a for-profit subsidiary of Tetra Tech, Inc. headquartered in Pasadena, California, operates as a prime contractor delivering facilities maintenance, infrastructure repair, and environmental remediation services to Department of Defense, Army Corps of Engineers, and Defense Logistics Agency Energy installations. The division competes full-and-open without set-aside designations across 133 recent awards worth a combined $503.1 million in potential value.
The EMI Division's customer concentration is heavily military and defense-logistics focused. The top five funding organizations by potential value—Department of the Army Corps of Engineers Engineering and Support Center ($175.7 million across 3 awards), GSA Federal Acquisition Service ($110 million across 14 awards), Defense Logistics Agency Energy ($77.2 million across 2 awards), Department of the Air Force Air National Guard ($30.8 million across 32 awards), and Department of the Navy Naval Facilities Engineering Command ($22.9 million across 7 awards)—account for 83% of combined potential value. The rankings reveal a dollar-concentration story: Army Corps of Engineers anchors most value through three massive facilities maintenance and repair orders, while the Air National Guard drives award volume through smaller individual procurements. Recent representative work includes a $64.9 million delivery order issued December 31, 2024, from Defense Logistics Agency Energy for recurring maintenance and minor repair of petroleum systems and facilities in the North Atlantic Division under GSA Multiple Award Schedule (completion June 30, 2030); a $52.4 million DLA Energy delivery order awarded May 15, 2024, for petroleum systems maintenance in the Northwestern Division (completion August 7, 2029); a $56.4 million Army Corps of Engineers Northwestern Division fuels maintenance delivery order awarded August 12, 2022 (completion February 12, 2028); and a $4.78 million U.S. Coast Guard remediation services task order awarded March 10, 2023, for seven sites in Rhode Island (completion March 9, 2027).
The EMI Division's footprint sits predominantly on the GSA Multiple Award Schedule, where 81 task orders carry a combined $359 million in potential value. It also holds positions on Army Corps of Engineers indefinite delivery contracts (21 task orders, $8.7 million) and facilities maintenance and management vehicles (11 task orders, $3 million). Work spans engineering services (87 awards by NAICS), facilities support services (22 awards), and environmental control systems (10 awards), with PSC coding concentrated in professional engineering and technical support (39 awards), management services (26 awards), and IT and telecommunications (13 awards). The division operates entirely as a prime contractor—100% of recent awards are prime—with no subcontract activity reflected in the source data.
Activity has been thin relative to the potential-value base: only two awards were recorded in 2024, one in 2023, one in 2022, and two in 2021, suggesting that the large dollar values concentrate in a small number of long-duration, multi-year maintenance contracts rather than frequent task-order placement. Two awards totaling $61.2 million in combined potential value face ultimate completion within the next twenty-four months, presenting recompete opportunity. GSA labor-portfolio data shows 74 active schedule categories spanning $59.27/hr laborer rates through $374.60/hr key-principal rates, with engineer, maintenance manager, quality control manager, and project manager roles typical of the division's facilities and engineering work. SCI-reported invoiced revenue on prime service contracts above the $150,000 threshold totaled $1.6 million across FY2023–FY2025 (FY2024 peak at $893 thousand), reflecting roughly 5.3 FTEs in FY2024 and median government-paid rates around $81.22/hr—a tight clustering indicating primarily labor-hour billing rather than tiered rates, and FTE volumes consistent with small-scale SCI reporting relative to the multimillion-dollar contract ceilings.
