Project Summary This project is to replace nine (9) evaporative coolers, eleven (11) exhaust fans, and wiring/conduit for air intake shutters throughout three greenhouses and a headhouse. The evaporative coolers have developed extensive leaks and have lost cooling capacity. Water has entered the conduit serving the air intake louver motors and has damaged the wire within. The exhaust fans in one greenhouse and the headhouse are old and do not meet current efficiency standards. This turnkey project consists of the following elements: 1. Remove existing evaporative cooling systems in three greenhouses, (9 total) and replace with new equipment per the specifications in this document. 2. Remove existing exhaust fan assemblies in Greenhouse #2 (7 total) and replace with new equipment per the specifications in this document. 3. Remove existing conduit and wiring between disconnect switch and intake actuator motors in three greenhouses and replace with new conduit and wiring. Statement of Work USDA, Agricultural Research Service Page 5 of 15 4. Remove existing exhaust fan assemblies in the headhouse breezeway (4 total) and replace with new equipment per the specifications in this document. 5. Perform electrical and mechanical checkout of the new system to ensure all steps have been completed according to the manufacturer’s documentation. 6. Provide start-up services by the manufacturer’s field service representative to commission the new system. 7. Provide training for the new system by the manufacturer’s field service representative. The facility will be occupied during construction activities. Power outtages to accommodate electrical tie-ins are to be scheduled in advance and coordinated with the facility representative to minimize the disruption to daily operations and research programs.
