About this file
This document is a Sources Sought notice for a federal contract opportunity related to upgrading the electrical system at the USDA ARS Northwest Irrigation & Soils Research Laboratory in Kimberly, ID. The project, referred to as "PROJECT II - Internal Building Transformers and Disconnects", involves replacing transformers and disconnect switches in various buildings on the site. The USDA is seeking information from qualified small businesses, HUBZone firms, service-disabled veteran-owned small businesses, 8(a) firms, veteran-owned small businesses, woman-owned small businesses, and small disadvantaged businesses to determine their capability to perform the work. Responses should include details on similar past projects, company size, and other relevant qualifications. This is not a solicitation for proposals, and the government is not obligated to make an award based on the responses received. The agency may issue a combined synopsis/solicitation on SAM.gov depending on the responses received by the deadline.
