Tetra TECH DLZ JV

Tetra TECH DLZ JV, a joint venture doing business as Tetra TECH, provides architectural and engineering (A-E) services and professional engineering support for federal civil works and infrastructure projects as a prime contractor under full-and-open competition, with no SBA set-aside designations across its recent federal footprint. The joint venture is a subsidiary of Tetra Tech, Inc., a global consulting and engineering firm based in Pasadena, California with an established track record across multiple federal agencies. Tetra TECH DLZ JV is headquartered in Bellevue, Washington and competes on a cash basis without minority or disadvantaged-business designations.

The joint venture's recent award activity reflects a narrow, specialized capability set centered on A-E services for U.S. Army Corps of Engineers civil works projects. Five prime awards totaling $8.8 million in combined potential value span two core service lines: architectural-engineering design and rehabilitation work on Corps water-resource infrastructure (dams, locks, gantry cranes, gate systems), and professional engineering support during construction for the Federal Highway Administration. Representative work includes a $582,191 delivery order from the Corps of Engineers for dam gate maintenance and bulkhead work at Montgomery Locks and Dam in Monaca, Pennsylvania (completed March 31, 2025), a $522,050 delivery order for gantry crane rehabilitation engineering in Saltsburg, Pennsylvania (June 2022), and a $14,997 purchase order from the Federal Highway Administration for professional engineering support during storm-damage repair at Mora Road in Olympic National Park, Washington (awarded July 2026, completion December 2027). The joint venture operates exclusively as a prime contractor—no subcontract activity appears in the source.

Customer concentration centers on the U.S. Army Corps of Engineers. The Corps' Pittsburgh District accounts for two awards totaling $7.7 million in combined potential value, the Corps' broader footprint accounts for two awards totaling $1.1 million, and the Federal Highway Administration accounts for $15 thousand. Tetra TECH DLZ JV holds a multiple-award indefinite-delivery contract with the Corps (ceiling $7.5 million, March 2022 through February 2027) under which three task orders have been placed, generating $1.3 million in combined obligated value. Award activity shows minimal recent volume—two awards in 2022, one in 2023, and two in 2026—with only one award ($15 thousand to the Federal Highway Administration) facing completion inside the next twenty-four months.
