Work includes removal of all redundant control panels, and wiring. Demolition of the existing controls is part of the control contractor scope of work. 1.3.1.2. Supply and install all the new BAS components (sensors, actuators, valves, operators, wiring, relays, controllers, panels, etc) required to make the new air handling systems operate in accordance with the sequences indicated on the drawings. 1.3.1.3. Remove any redundant timers and associated wiring and devices controlling the demolished equipment. 1.3.1.4. The temporary removal of the Air Sniper sanitizing equipment controls and reinstatement. 1.3.1.5. Update existing programming and user interface as required to match the sequence of operation indicated on the drawings; c/w graphical displays on the Board main server to match the new equipment layout and configuration. 1.3.1.6. Provide all necessary power wiring and hardware to complete the entire project, including but not limited to, wiring, fittings, connectors, conduits, hangers/supports, box covers, BAS control panels, and all other accessories required to ensure complete,safe and fully operationalsystems.

Update software and graphical interface as required. 1.3.1.12. All line and low voltage wiring shall be run in EMT metal conduit. 1.3.1.13. Control wiring installed in exposed areas (common areas, mechanical rooms, outdoors) shall be run in IMC rigid metal conduit 1.3.1.14. Control wiring installed in the ceiling space shall be plenum rated and does not require rigid conduit. Any controls wiring in ceiling spaces is to be run in a cable management tray, and transitions from the tray shall neatly follow the building structure and any wall penetrations must be sleeved in conduit with nylon bushings. 1.3.1.15. Include all wiring, conduit, piping, installation, materials, supervision and labor including calibration, commissioning software programming and data base generation, and additional work necessary to provide a complete and fully operating system to the approval of the Consultant. 1.3.1.16. Controlssub-contractorshall coordinate with the electricalsub-contractor forthe location of breakers and junction boxes from which power to the control's equipment will be provided.
