About this opportunity
The Department of the Army Materiel Command Contracting Command Rock Island Arsenal awarded a sole-source contract modification worth $8,338,855.71 to TETRA TECH, INC. for base operation services at Chemical Material Agency - West on September 17, 2025. The contract modification exercises an unevaluated option year two under the existing cost-plus-fixed-fee contract W519TC23C2031, extending services for an additional six-month period from September 2025. These base operation services support the facility's closure mission, which involves a five-phase process including decontamination, decommissioning, disposition, demolition, and administrative closeout related to the Pueblo Chemical Agent Destruction Pilot Plant. The Army determined that competing this contract would result in substantial duplication of costs and operational disruptions, making Tetra Tech's continued support the most cost-effective approach for the facility's safe and compliant closure.
