This sources sought notice is market research to support including sole-source brand-name specifications for a generator control system in a larger construction project at Fort Greely, Alaska, and is not a request for proposal. The government intends to specify replacement of existing Genius Bus Controllers with Profibus Controllers (IC695PBS300) in two switchgear ENIU racks, and replacement of Genius Blocks with RSTi-EP blocks using Profibus scanners (EPXPBS001) and 16-point digital input/output modules (EP-125F/EP-225F). These sole-source items would be incorporated into a FY26 solicitation for the Fort Greely construction project, and no separate solicitation will be available. Vendors that can meet the functional criteria are invited to respond with the manufacturer’s name, address, country of manufacture, detailed specification sheets, and a narrative showing how their product meets the listed features.
