The Department of Defense, specifically the U.S. Army Corps of Engineers, Detroit District, is conducting a Sources Sought notice to identify potential contractors for oil filtration and maintenance services for the ABB transformer located at the St. Marys Falls Canal in Michigan. The contractor will be responsible for filtering oil, providing high-quality FR3 fluid, installing government-supplied valves and sample ports, and implementing infrared windows for thermal imaging of transformer components, along with providing training for maintenance. This opportunity is crucial for ensuring the operational efficiency and safety of electrical equipment, and responses are encouraged from both small and large businesses, with a deadline for submissions set for 2:00 PM (Eastern) on December 29, 2025. Interested parties should contact Noah Bruck at noah.r.bruck@usace.army.mil or Michelle Barr at michelle.barr@usace.army.mil for further details.
