The National Oceanic and Atmospheric Administration (NOAA) intends to award a sole-source, firm-fixed-price contract to Siemens Industry Inc. for comprehensive maintenance of the Siemens Desigo CC HVAC and Energy Management Control System at the NOAA Mississippi Laboratory. The scope includes onsite maintenance, remote diagnostics, software subscriptions, and cloud-based monitoring via the Building X platform. This action is justified due to Siemens' proprietary expertise in the legacy TEC P2 communications system, which is not available on the open market. The anticipated award date is July 2026, and the performance location is the NOAA Mississippi Laboratory. No budget amount is specified in the description.
