The Department of Energy, through Battelle Energy Alliance, is seeking Expressions of Interest (EOI) from qualified vendors for roof replacement services at the PBF-613 facility located within the Idaho National Laboratory in Idaho Falls, Idaho. The project entails replacing an aging built-up tar and gravel roof across four distinct zones, totaling approximately 6,550 square feet, and includes the removal of existing equipment such as a blower and HEPA housing, along with capping electrical and ducting on Zone 1. This initiative is part of BEA's broader infrastructure maintenance and modernization efforts at the laboratory, which plays a critical role in nuclear energy and clean energy innovation. Interested vendors must submit their EOIs by April 1, 2026, including relevant company information and experience, to Chase Egbert at chase.egbert@inl.gov, as only selected respondents will be invited to participate in the subsequent Request for Proposals (RFP) process.
