This Justification Review Document is for a sole-source contract extension with Tetra Tech (TTEK) for Base Operation Services at the Chemical Material Activity - West (CMA-W), a facility undergoing closure. The contract will extend services for an additional six-month period from September 2025, with the total contract covering base and option periods. The extension is critical to support the facility's closure mission, which includes five phases: decontamination, decommissioning, disposition, demolition, and administrative closeout related to the Pueblo Chemical Agent Destruction Pilot Plant.

The U.S. Army Contracting Command - Rock Island (ACC-RI) determined that competing the contract would result in substantial duplication of costs, operational disruptions, and unacceptable delays. Tetra Tech has demonstrated expertise in the facility's unique operational requirements, safety protocols, and hazardous material handling. The contract is a cost-plus-fixed-fee modification, with the government concluding that TTEK's continued support is the most cost-effective approach to ensure a safe, compliant, and timely completion of the facility's closure mission. Market research was conducted, with 16 businesses responding to a sources sought notice, but the government determined that transitioning to a new contractor would be impractical and cost-prohibitive.
