GOC372667-CT - Replace Damaged Fresh Air Dampers Level B1

Replace existing dampers at the B1 Level wood working shop associated with the two air handling units located within the Library & Archives Wood Working Shop. Install new actuators and controls as required and ensure the entire system is calibrated and communicating correctly with the building’s existing BAS system.
In addition to the new damper, the existing AHUs would be replaced with two new AHUs.
In the new AHUs the cooling coil would be located downstream of the heating coil, eliminating the need to manually isolate and drain the cooling coils in the winter as the air passing the cooling coil will never be below freezing. The control valves for the cooling would be replaced, as the existing valves appear to be at the end of their lifecycle. In addition, control valves would be added the heating coil to eliminate the need for human intervention during seasonal changeover.
To properly control the space temperature, all of the control devices would be added to the BAS. With the system on the BAS the temperature control will be fully automated, and heating or cooling will be provided based on the space temperature trends.
There are many pieces of equipment within the space that have a dedicated exhaust system for dust extraction. With the installation of a new AHU, the entire area can be analyzed to ensure that an appropriate amount of outdoor/make-up air is being provided to the space to replace the exhausted air. The new AHUs will be sized to be able to handle the additional outdoor air drawn into the space to replace the exhausted air.
