Specifications include, but are not limited to: a. Replace the existing old JC80 BAS system according to this SOW. b. Integrate the new BAS controllers with either the campus Andover Continuum or Siemens Apogee front end system that meets the latest published UT DDC Controls specification. c. Design the new BAS to be robust. This typically means a separate controller for each major group of HVAC equipment providing reliable building control even if network communication or other building controller(s) fail. Discuss with the UT PM. d. Pre-build and test BAS front end screens, field panels, control devices, and wiring such that point transfer time between old and new controllers is minimal. e. UT will provide a FACNET drop to the BAS network controller panel, and will supply IT support, if needed, for the FACNET interface. FACNET is a UT protected, secure, malware free, limited access facilities network. To protect it, only FACNET dedicated and new or guaranteed malware free computers may connect to it. f. Building access is expected to be during normal working hours. Schedules and work areas will be depend on building use and are subject to change. Coordinate and communicate the work schedule with the building contact. g. Notify UT of any discrepancies, omissions, additions or conflicts in completion of the project as described in a timely manner. h. Notify UT Facilities Monitoring (471-3935) each day before working on any operating BAS system. a. Replace the existing old JC80 BAS controllers with 1 new BAS system with 1 network controller and 1 FACNET drop. See the attached existing point list. Return the old working hardware to the Zone 3 maintenance shop for spares. b. Furnish and install new panels, equipment controller(s), expansion modules, and other devices required for transfer of all existing and new BAS points into new controllers. Provide spare I/O and panel space in each mechanical room per the BAS specification. c. The new BAS may reuse existing conduit, wiring, panels, or field devices that are compatible with the new system and are in good working condition. d. If available, use the existing 120V power circuit for new the control panels. If not available, UT will install a new 120V circuit from the most convenient circuit breaker panel. Inform the UT PM where new control panel 120V circuits are needed. e. Use terminal strips to connect old and new wiring, not wire nuts. f. Install new sensors and devices as shown on the P&ID drawings (dark font). g. Install EPTs to drive existing pneumatic actuators. Match each EPT output air signal range to each actuator. h. Remove the existing pneumatic speed command signal to each VFD. Replace with an electronic speed command signal. i. If needed, provide UPS power for the network controller and the other controllers in the same mechanical room according to the latest BAS Specification Section 3.7. Do not provide UPS for the other mechanical rooms. j. If they exist, replace each motor starter Momentary Start/Stop button and associated relays with an HOA switch and a new S/S relay. Both the H and A positions must be wired in series with the existing equipment safety switches. Cover the resulting blank holes in the starter panel.
