The Department of Defense, through the 55th Contracting Squadron at Offutt Air Force Base, Nebraska, is seeking potential sources for the replacement of obsolete Excel 5000 series controllers at Facility B583. The objective of this procurement is to install new Honeywell Tridium N4 controllers, ensuring the migration of existing data and the updating of systems to maintain operational consistency, while adhering to strict cybersecurity and quality assurance standards. This project is critical for Airfield Control operations, as the current controllers have reached their end of service life, leading to significant delays in repairs. Interested parties are invited to submit their capabilities by 12:00 PM (CST) on November 14, 2024, to the primary contacts, Elizabeth Shearns and Austin D. Palrang, via the provided email addresses. Note that this is a sources sought notice for planning purposes only, and no funds are currently available for this effort.
