Fermilab -Replacement of EOL water-cooled HVAC system

This statement of work (SOW) aims to obtain supervision, expertise, labor, materials, and equipment for the work indicated below.

The work will be completed at Proton West 7 (PW7) at the Fermilab facility in Batavia, Illinois. Fermilab is operated by the Fermi Forward Discovery Group (FFDG). FFDG will provide a Task Manager / Construction Coordinator (TM/CC) to oversee the project.

The subcontractor will replace the existing water-cooled HVAC unit at PW7. The subcontractor will purchase and provide the replacement unit. This is an end-of-life replacement of the HVAC system.

The subcontractor will be responsible for all installation, labor, supervision, equipment, measurements, programming, and testing needed to complete this project before turning it over to FFDG.
