This is a market research request for HVAC control systems that must be fully compatible with existing Johnson Controls infrastructure for two construction projects at Minot Air Force Base, North Dakota. The total estimated product cost for the required systems is approximately $330,000, with individual project estimates of $130,000 and $200,000. The government is specifically seeking information on potential alternate brands that could meet the requirement for interoperability with the Johnson Controls systems already in place. Responses to this sources sought notice are due by 2:00 p.m. Central Time on 22 April 2026. This is not a solicitation, but information gathered will help determine if the eventual procurement will be full and open or will include a brand-name justification.
