NOAA intends to award a sole-source purchase order to Johnson Controls for an upgrade and replacement of its Metasys commercial HVAC building automation system. The work will be performed at 31-35 East Quay Rd, Key West, FL 33040. Delivery is required within 180 days from date of award. The sole-source justification is based on the need for brand-name Metasys components to integrate with NOAA's existing enterprise system, as non-Metasys parts are incompatible. This notice is not a request for competitive proposals, but interested firms may submit substantiating documentation for consideration.
