TerraCon Consultants Inc. provides specialized environmental and engineering consulting services focused on site assessment, remediation planning, and regulatory compliance for federally funded infrastructure and land management projects. Their core capabilities include Phase I and II Environmental Site Assessments, RCRA and CERCLA compliance support, groundwater modeling, and hazardous material management. The firm applies technical expertise in soil and sediment analysis, contaminant fate and transport modeling, and EPA regulatory frameworks to deliver science-driven solutions for complex environmental challenges. Their differentiation lies in integrating field data with geospatial analysis and risk-based decision tools to support defensible, audit-ready documentation for federal and state regulators. Award history is not available to confirm specific agency relationships or recent contract performance. As a result, no definitive patterns of engagement with federal departments can be inferred from the provided data. The company operates under NAICS 541330, which classifies it as an environmental consulting services provider. In practice, this means they deliver technical services related to environmental impact assessments, regulatory permitting support, and cleanup strategy development—primarily serving sectors requiring compliance with federal environmental statutes such as NEPA, CERCLA, and the Clean Water Act. Their market positioning centers on niche, compliance-intensive environmental engineering work rather than broad-scale construction or remediation implementation. TerraCon Consultants Inc. is a small, privately held business structured as a 2L entity, indicating it is owned and operated by individuals rather than a corporation or consortium. The firm is headquartered in Boise, Idaho, and maintains a regional footprint in the Western United States. While no government certifications are currently listed, their operational model aligns with the standards expected of professional environmental consultants serving federal clients, including adherence to ASTM and EPA protocols.

Sources Sought / Market Intelligence: Multi-Projects for Army Reserve Program – Construction Management at Risk (CM@Risk) utilizing Other Transaction Authority (OTA)
Solicitation # W912QR-CMAR-ArmyReserveDevensSheridanPatton
The U.S. Army Corps of Engineers, Louisville District, is conducting a Request for Information to gather market intelligence for three separate military construction and sustainment projects for the Army Reserve program. The government is evaluating a Construction Management at Risk (CM@Risk) delivery strategy executed under Other Transaction Authority (OTA) pursuant to 10 U.S.C. section 2808a. This approach aims to utilize commercial best practices and streamlined delivery models to accelerate schedules and improve cost transparency. The three projects under consideration include a 46,000 square foot Collective Training Enlisted Barracks at Devens Reserve Forces Training Area in Massachusetts with an estimated value of 35 to 45 million dollars, a 19,000 square foot Area Maintenance Support Activity facility at Fort Sheridan in Illinois estimated between 30 and 40 million dollars, and a 1,500 square foot Parachute Drying Tower at Patton USARC in California estimated between 5 and 15 million dollars. The planned acquisition strategy involves a two-phase execution. Phase 1 focuses on preconstruction services, including constructability reviews and value engineering, compensated by a firm-fixed-price fee. Phase 2 transitions the contractor to an at-risk general constructor under a negotiated Guaranteed Maximum Price (GMP) for construction execution. The government is seeking detailed information from industry regarding OTA experience, CMAR capabilities, bonding capacity, and technical expertise in specialized military facilities. Interested firms must submit their responses exclusively via the designated online survey form by October 5, 2026, at 11:00 AM Eastern Time. This RFI is for planning purposes only and does not constitute a formal solicitation or a commitment to award a contract.
