The Department of Energy's National Renewable Energy Laboratory (NREL) is seeking qualified subcontractors for the installation of a new Tempress Diffusion Furnace in the Science and Technology Facility (S&TF) cleanroom at its Golden, Colorado campus. The project requires contractors to have experience in cleanroom environments and the ability to manage modifications to ductwork, mechanical and electrical systems, and gas detection, while ensuring minimal disruption to ongoing research operations. This initiative is crucial for enhancing NREL's capabilities in renewable energy research and development, with a project duration anticipated to exceed six months. Interested parties should submit a Capabilities Statement to Evan Buzbee at evan.buzbee@nrel.gov, as the opportunity emphasizes small business participation and timely completion is essential for operational milestones.
