York Campus Construction Requirements Project 6264A-18-204 Upgrade Energy Management System GENERAL INFORMATION Introduction: The VA s existing Building Automation System (BAS) Direct Digital Controls (DDC) systems are manufactured by Siemens and Alerton. The Engineering Control Center (ECC) is in the chiller plant and the Boiler Plant Operator Room. These systems currently operate via V-LAN (Virtual Local Area Network) and fiber RS-485. These control systems, along with many of their outdated control panels, manage various Air Handling Units, Chiller, and Boiler plant operations. Present DDC systems are a mix of proprietary and non-backwards compatible frameworks that are incapable of functioning as a system to allow control as required across the facility. This requirement will upgrade the existing Energy Management System and Building Automation System and remove existing system(s) in Buildings at TVHS Alvin C. York VA Medical Center. This solicitation will result in one award for the project. Scope of Work: Provide construction services to upgrade existing Energy Management System to Desigo CC or equivalent and Building Automation System for Project 6264A-18-204 at the Tennessee Valley Healthcare System Alvin C.
