A System with Chiller Plant Manager to manage the operation of Chillers, Cooling Towers, Pumps, Valves etc., is already specified as part of the larger HVAC work and is under implementation. (Niagara based Software and JACE with Honeywell DDC Controllers).
319It is planned to integrate the other devices such as AHU, FCU, CSU, etc., into the existing system as part of this tender. Hence it is preferable that the tenderer uses the same software and DDC\"s with additional licenses as necessary. However, in case the vendor wishes to quote for a different brand/version of software, they may do so by offering their own Servers, Software and integrate the existing BMS system into the new system so that the entire system can operate as one seamless system from the new BMS system.
320All components of the BMS System shall be designed to ensure that events and data are reflected on the BMS Server with minimum delay time.
