W.G. (Bill) Hefner Department of Veterans Affairs Medical Center 1601 Brenner Avenue Salisbury, North Carolina 28144 Subject: Statement of Work: Install Campus Energy Management System Location: Campus Project #: 659-22-100 Date:

12 December 2025 STATEMENT OF WORK Mechanical General: The project involves the upgrade and consolidation of the Energy Management Systems (DDC) providers serving Buildings 2 on the Salisbury VAMC Campus. The new system will follow Native BACnet protocol and be able to replace existing JCI and Schneider components with a single front-end user interface compatible with Siemens. This project is to convert systems from both pneumatic controls and obsolete DDC controls to the Siemens Desigo Native BACnet central system, where applicable, for Buildings 2. This project should be completed in 365 days and include a 1 year warranty on all items.

SCOPE OF WORK: The

Scope of work associated with the project includes the following: Network & User Interface Appropriate modifications to the existing network and cabling layout (Ethernet & MSTP) for the purpose of integration, including the installation of new Desigo panels. Terminal Unit Controls

• 1) Modifications required to replace the Tridium/Niagara controls with BACnet, Siemens Desigo compatible controllers and sensors (where required). Include in the recommendation, devices that can remain (relays, switches, valves, damper motors, sensors, etc.) To include the following:
• (i) New Siemens server to replace the existing Siemens server.
• (ii) Front-End Graphical User Interface modifications, including new floor plans for every level of Buildings 2.
• (iii) Main equipment panel and controller installations.
• (iv) Panel installations.
• (v) Panel modifications and replacement, and controller replacements, required on the main systems.
• (vi) Ethernet-level networking modifications.
• (vii) BACnet MSTP networking modifications.
• (viii) Pneumatic terminal-unit controller replacements.
• (ix) Removal of the compressed air system serving control components and devices. to include all hardware, software, installation, wiring, cabling, programming of systems, graphics, and setup of alarms, schedules and trending; as well as networking

requirements required to into a new Siemens server in accordance with the VA standards.
