The U.S. Department of State, through the American Embassy in Geneva, intends to award a sole-source contract to Honeywell for the upgrade of its Building Automation System (BAS). This procurement aims to enhance the existing BAS server and software, which are critical for managing HVAC and lighting systems within the Chancery building. Given the proprietary nature of Honeywell's technology, including unique controllers and network infrastructure, the company is deemed the only qualified provider for this upgrade, as justified under FAR 6.302-1. The estimated cost for this project is $45,000, and the primary contact for this procurement is Contracting Officer Gavin Eliott. This notice is not a request for competitive proposals, and a Justification for Other than Full and Open Competition (JOFOC) has been prepared in accordance with FAR 6.305.
