About Tetra TECH Inc.

Written by GovTribe AI ·

Tetra TECH Inc. is a large, global consulting and engineering firm headquartered in Pasadena, California, with an Atlanta division that serves as a prime contractor to the federal government. The company specializes in providing architect-engineer (A-E) services, environmental compliance and assessment support, infrastructure planning, and technical consulting to federal agencies. Tetra TECH brings substantial expertise in environmental remediation, facility design, regulatory support, and complex infrastructure projects, with an established track record of managing sophisticated technical and environmental initiatives for the Department of Defense, U.S. Army Corps of Engineers, EPA, and other federal agencies.

Through its recent prime federal contract awards, Tetra TECH's Atlanta division has delivered specialized services centered on environmental regulatory support and mission sustainment for the Department of Defense. Most notably, the company received a $13.8 million firm fixed-price delivery order from the Air Force (ENDIST Mobile) on September 25, 2025, for regulatory mitigation and monitoring services supporting the Sentinel Test Program at Vandenberg Space Force Base, with performance extending through September 24, 2029 and work conducted at Hill Air Force Base in Utah. Additionally, Tetra TECH secured a $7.15 million delivery order from the Air Force Civil Engineer Center (ENDIST Mobile) on September 24, 2025, for Community Partnership and Mission Sustainment Encroachment Management Support services in Mobile, Alabama, with completion scheduled for September 24, 2026. Both delivery orders were issued under the Architect and Engineering Services to Support the USACE South Atlantic Division master Indefinite Delivery/Indefinite Quantity contract vehicle, carried no small business set-aside designations, and reflect the company's capability to address complex environmental assessment, compliance monitoring, land-use planning analysis, and strategic consulting requirements for military installations. A third delivery order issued on January 3, 2025, relates to a minimum guarantee provision under the same IDIQ master contract.

Tetra TECH holds a significant prime federal contract IDV—a $249 million multiple award Indefinite Delivery Contract awarded by the U.S. Army Corps of Engineers (USACE), Mobile District, with a period of performance through December 30, 2029. This master IDIQ vehicle supports the USACE Mobile District's Planning & Environmental Division and encompasses architect-engineer services across a broad geographic area including the southeastern United States, Central and South America, and other global locations. The contract scope includes environmental compliance, planning, conservation, NEPA documentation, and supporting studies for both military and civil works projects, requiring expertise across multiple disciplines such as program and project management, environmental engineering, biology and ecology, water resource planning, cultural resources assessment, socioeconomics, geotechnical engineering, and coastal engineering. The delivery orders that Tetra TECH has received to date—including those for the Sentinel Test Program and encroachment management support—are issued directly under this master IDIQ vehicle, positioning the company as a key provider of integrated planning and environmental services for the USACE South Atlantic Division region.
