Terradon Corp

Terradon Corp, a woman-owned small business based in Poca, West Virginia, delivers civil engineering, surveying, geospatial mapping, and infrastructure inspection services to the U.S. Army Corps of Engineers and the Department of the Interior as a prime contractor (100% of recent awards), competing predominantly under Total Small Business set-asides on indefinite delivery contracts and delivery orders. The company is a for-profit Subchapter S corporation with no recorded subcontract footprint.

Terradon's customer base is heavily concentrated with the Army Corps of Engineers. The top five funding sources account for 97% of recent awards, dominated by the Department of the Army Corps of Engineers (36 awards, $68.3 million combined potential value), followed by the Department of the Interior Fish and Wildlife Service Region 9 (one $50 million indefinite delivery contract), the Corps Engineering District Huntington (19 awards, $2.1 million), the GSA Federal Acquisition Service (one $2 million Federal Supply Schedule contract), and the Department of the Army Corps of Engineers Finance (one $1.4 million contract). The potential-value ranking diverges slightly from award count, with the Interior Department's single large MATOC (Multiple Award Task Order Contract) for architectural and engineering services anchoring 40% of total potential value despite representing only one award.

Terradon holds four primary vehicle positions. The company sits on a $35 million multiple-award indefinite delivery contract with the U.S. Army Corps of Engineers Huntington District for geospatial and architectural-engineering services (awarded May 2022, running through May 2027) under Total Small Business set-aside, through which nine task orders totaling $1.55 million have been placed for boundary surveys, topographic surveys, and tract surveys supporting Section 202 civil works projects in Kentucky, Virginia, and West Virginia. The company also holds a single-award $25 million indefinite delivery contract with the Corps for design services in the Great Lakes and Ohio River Division (August 2021 through August 2026), which has funded major projects including a $1.39 million Soo Lock sewer rehabilitation design in Michigan, a $1.11 million Section 219 Delafield Avenue stream inflow project in Pennsylvania, a $401 thousand Clendening Tunnel repair project in Ohio, and a $406 thousand Delaware Spillway Bridge rehabilitation design in Ohio. A $50 million multiple-award MATOC with the Department of Interior Fish and Wildlife Service (September 2022 through September 2027) covers architectural and engineering services across Interior and Forest Service requirements. Additionally, Terradon was awarded a $2 million GSA Federal Supply Schedule contract (May 2025 through May 2030) under Special Item Number 541330ENG for engineering services, with hourly labor rates spanning $59.51 to $276.63 across 27 categories including Engineering Technician, Professional Land Surveyor, Environmental Specialist, and Principal Landscape Architect roles; no security-cleared positions are offered.

Terradon's concrete capability portfolio centers on boundary and topographic surveying, civil engineering design, infrastructure inspection and rehabilitation, geospatial mapping and three-dimensional modeling, hydrographic surveys, and subsurface utility engineering. Representative work includes a $279 thousand FY25 bridge inspection delivery order with the Corps Huntington District (May 2025, completing September 2025), a $212 thousand boundary survey for Yatesville Lake, Kentucky (September 2024, due June 2025), a $198 thousand FY24 bridge inspections delivery order (April 2024, completed September 2024), a $164 thousand ground current investigation in Romeoville, Illinois (May 2024, due May 2025), and an $83 thousand Dickenson County, West Virginia tract survey (July 2022). Work is performed across multiple states with administrative oversight and primary performance in Huntington, West Virginia, Poca, West Virginia, and additional offices in Pennsylvania and Virginia.

Activity has declined from 11 awards in 2022 to one award in 2026, with a slower pace in 2023–2025 (nine, five, and three awards respectively). The 2024–2025 decline from the earlier 2022–2023 pace reflects a narrowing of task order frequency against the established IDVs. The recompete window is minimal: only three awards (combined potential value $2.1 million) complete within the next twenty-four months, presenting limited immediate recompete exposure against current vehicles. Combined potential value across all awards totals $123.8 million, but only $8.1 million has been obligated (7%), indicating the bulk of value remains available under the company's indefinite delivery vehicles rather than in firm task orders.

Terradon competes entirely under Total Small Business set-aside designations for its indefinite delivery contracts, though the majority of individual delivery orders against those vehicles are issued without set-aside restrictions once the underlying IDV is set-aside-protected. The company registered in the System for Award Management in 2001 and does not serve as a subcontractor to other prime contractors within the source data.
