5 General Notes. See H sheets for scope of work details on finned tube radiation valves, hot and chilled water system components, unit heaters and heat pumps.. Abbreviations: T.C.C. = Temperature Controls Contractor, M.C. = Mechanical Contractor. All work to be in electrical metallic tubing (EMT) in mechanical rooms, plenum rated cable above accessible ceilings for Class II circuits per all applicable state, local and federal codes including but not limited to NEC.. M.C.C. shall be the prime contractor and shall assume the responsibility to prevent service outages during construction through coordination with subcontractors and the Owner. 5. Blank plates shall be installed to cover variance in opening left by existing thermostat as comparted to the new thermostat.. Test and Balance scope X. Test and balance required at each air flow at each VAV, use original air flow schedule, adjust flow as required to satisfy load. Grilles and diffusers not included in test and balance work. Re-sheaving is not part of this scope of work. Intent of this project is to have a neutral to slightly positive building at the conclusion of the project KEYED NOTES:. T.C.C. to replace existing pneumatic VAV unit controls with new DDC VAV controller with integral actuator and discharge air temp sensor. Connect tubing to air flow sensor from controller. Extend bus communications and power to each DDC controller. M.C. to replace existing pneumatic reheat control valve actuator with electric control valve actuator and cut and cap pneumatic air lines at each VAV.. M.C. to cut and cap pneumatic air lines as required and remove existing thermostat. T.C.C. to provide new DDC thermostat in same location and wire to controller specified in V. (if unspecified wire to nearest DDC controller).. T.C.C to provide DDC start/stop relay and current switch for exhaust fan and wire to controller specified in V.. M.C. to cut and cap pneumatic air lines as required.. T.C.C. to replace existing pneumatic fan powered box controls with new DDC VAV controller with integral actuator, discharge air temp sensor, and relays as required. Connect tubing to air flow sensor from controller. Extend bus communications and power to each DDC controller. M.C. to replace existing pneumatic reheat control valve actuator with electric control valve actuator and cut and cap pneumatic air lines at each VAV. 5. Provide ceiling mounted occupancy sensor as required. Wire to controller specified in V.. Install relays as required. 6. M.C. to cut and cap pneumatic air lines as required and remove existing thermostat and humidistat. T.C.C. to provide a DDC thermostat in the same location and a wall mounted CO sensor. Wire both devices to controllers specified in V
