Tenders are invited for HVAC Energy Saving Measures and Controls Replacement

HVAC Energy Saving Measures and Controls Replacement project is to provide a complete replacement of the existing JCI Metasys Building Automation System with a system that meets the NCNG Building Automation System standards. It will not be acceptable to reuse the existing JCI controllers for this renovation in any way. It is the intent of the renovation that the currently selected CSI (Controls Systems Integrator) will be contracted as indicated in the standard BAS specifications for the CSI scope of work. The currently installed JCI Building Automation System consists of a UL864 smoke control rated system serving all AHU’s, Fans, and VAV boxes, and a non-smoke rated system serving HW and CHW plants and all integrations. Due to the nature of the mechanical design, the BAS renovation will have to conform to this implementation method. The existing smoke control and/or Fireman’s Control panel is intended to remain as installed unless found inoperable, should it be found inoperable its repair or replacement will be performed outside of the base scope of this contract. Existing wiring is BACnet MSTP between controllers and may be re-used in areas where it is found to be intact
