About the company
Terracon Consultants Inc., doing business as Terracon Consultants #15, is a subsidiary of Tsvc, Inc. that operates as a subcontractor (75% of recent awards) on federal construction and engineering projects, with occasional prime work. The vendor delivers third-party testing, emissions performance testing, and geotechnical or materials-testing services supporting military construction, Army Corps of Engineers programs, and USDA facilities work.
Terracon is a child entity within the Tsvc, Inc. corporate structure and competes across construction and engineering NAICS categories — Commercial and Institutional Building Construction, Other Building Equipment Contractors, and Engineering Services — without identifiable SBA set-aside designations in the recent award footprint. The vendor's activity is sparse: four total awards spanning from 2008 through November 2025, with a combined potential value of $50 thousand against $334 thousand in obligated dollars — an unusual ratio reflecting small contract values or task orders that have accrued significant spend relative to stated ceiling. The most recent activity shows two awards in 2025, suggesting renewed engagement after a three-year gap (2022 to 2024).
Customer concentration is diffuse across three federal agencies, each representing one award within the recent footprint: the Department of Agriculture's Agricultural Research Service (Plains Area field research), the Department of the Army Corps of Engineers' Sacramento District, and the Department of the Army Corps of Engineers' Little Rock District. The vendor places work under two Corps of Engineers parent vehicles: the Vertical Architectural-Engineering Services for Military Design and Interagency & International Services (South Pacific Division) contract and the Unrestricted Vertical MATOC for the Ft. Worth District (2024–2029).
Representative subcontract work includes third-party testing support for a Gilbane Federal JV design-build renovation of five buildings for the Royal Singapore Air Force at Eielson Air Force Base, Arkansas (awarded November 2025); geotechnical or materials testing for an HDR Engineering MC-130J Hangar and Aircraft Maintenance Unit design-build project at Davis-Monthan Air Force Base, Arizona (awarded October 2025); and emissions performance testing of medical waste incinerators for a Firelake Construction USDA National Bio and Agro-Defense Facility contract (awarded March 2022). SCI-reported activity is minimal — 0.1 FTEs in FY2025 as a named subcontractor on a single federal service contract above the $150,000 threshold, indicating limited visibility in the federal service-contract reporting system and no identifiable prime service delivery in that dataset.
