About this IDV
The U.S. Department of Energy's Office of Environmental Management awarded an indefinite-delivery contract to Hanford Mission Integration Solutions, LLC on December 5, 2019, with a $5.68 billion ceiling. It is a single-award vehicle with no set-aside. The Hanford Mission Essential Services Contract (HMESC) supports mission essential services at the Hanford Site in Richland, Washington, and its ultimate completion date is September 30, 2028. Hanford Mission Integration Solutions is a subsidiary of Leidos Holdings, Inc.
The originating pre-solicitation was posted October 19, 2017, with proposals due November 19, 2018. It anticipated NAICS 541611 and PSC R499 and stated the performance period would run as long as needed to complete all mission essential services at the Hanford Site. The source notes the incumbent was expected to propose and that the contracting officer's preliminary organizational conflict of interest analysis could affect teaming arrangements.
The most recent order under this IDIQ is a $34.9 million cost-plus award fee delivery order, awarded August 15, 2025, for Reliability Task Order-012 (RPTO-012), Project L-888, Eastern Plateau Fire Station. It runs through August 31, 2028, and carries no set-aside. A modification incorporated the RPTO-012 Performance Evaluation and Measurement Plan as Attachment J-4. A separate modification provides incremental funding for CLINs 1004 and 1006 for contract work scope.
