1.             Provide new temperature controls.

2.             Replacing exhaust and supply air flow sensors in all labs.

3.             All new control valves, damper actuators, temperature and pressure sensor for all 6 AHUs.

4.             Replace all supply and exhaust VAV boxes including actuators and controls.

5.             Re-balancing of room air flows and all coil water flows.

6.             Remove all Pneumatic controls and pneumatic air system.

7.             Replace the 6 existing Air handling units (AHUs) with new AHUs.

10.         Replace 6 lab exhaust fans on roof with 2 new coil to coil heat recovery exhaust systems.

11.         Rebalance the supply and exhaust air systems to establish 10 air changes per hour in the lab spaces and a pressure differential of -0.05" in the laboratory to keep the laboratory negative relative to the corridor.

12.         Provide two new hot water preheat coil systems including dual pumps and converters and all controls.

13.         Provide two new glycol heat recovery coil systems including dual pumps and converters and all controls.
