About this award

Written by GovTribe AI ·

Leidos, Inc., operating through its Leidos Services Operating Segment (doing business as SAIC), was awarded a definitive cost-plus-fixed-fee contract by the U.S. Army Corps of Engineers on August 31, 2023, with a ceiling value of $16.3 million and an ultimate completion date of March 3, 2025. This modification 9 partial deobligation represents continued support for the St. Louis North County Sites project located in Hazelwood, Missouri. The contract supports the Formerly Utilized Sites Remedial Action Program and encompasses hazardous, toxic, and radioactive waste verification, laboratory, and environmental services, including low-level radioactive contaminated material investigation, extent of contamination surveys, environmental assessments, and on-site laboratory analysis. The scope addresses radiological contaminants including thorium, radium, and uranium, as well as co-located chemical contamination such as selenium, cadmium, and arsenic across multiple sites in the St. Louis metropolitan area and the Iowa Army Ammunition Plant in Burlington, Iowa.

The contract includes provisions for radiological and health physics technical support, with the on-site laboratory required to maintain accreditation through the American Association for Laboratory Accreditation. No small business set-aside designation was applied to this award, reflecting Leidos' competitive capabilities. As a child entity of Leidos Holdings, Inc., the contractor operates within a broader portfolio that includes significant indefinite delivery contracts with the Army Corps of Engineers and other federal agencies, positioning the company to deliver comprehensive technical and environmental remediation solutions across complex government missions. The Army Corps of Engineers St. Louis District manages this project under the broader environmental remediation initiatives supporting formerly contaminated military and government sites.
