The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to award a sole source contract for maintenance and repair services of an SGT-600 gas turbine at the NIH Bethesda Campus Cogen Facility. This procurement, classified under NAICS code 561210 for Facility Support Services, aims to ensure the operational efficiency and reliability of critical energy infrastructure. The contract will be a firm-fixed-price task order with a base period and four option years, and while it is a notice of intent rather than a request for quotes, other interested parties may submit capability statements by December 18, 2025, at 10 AM EST. Submissions should be directed to Anazette Andrews at andrewsa3@mail.nih.gov, and offerors must be registered in SAM.gov to participate.
