INTRODUCTION

Fermi National Accelerator Laboratory (FermiLab) is seeking a subcontractor to provide preventative and corrective maintenance services for heating boiler systems at the facility. The Fermilab site is 6,800 acres and is owned by the Department of Energy (DOE) and operated by the Fermi Forward Discovery Group (FFDG).

This Statement of Work defines the scope, terms, and conditions for providing preventative and corrective maintenance services for heating boiler systems to ensure continued safe, reliable, and efficient operation.

The subcontractor shall provide all labor, materials, equipment, and supervision necessary to perform the work indicated in the scope of work below. A Service Coordinator will be assigned to provide oversight of the project.

SCOPE OF WORK

Preventative Maintenance (PM)

The Subcontractor shall provide scheduled preventative maintenance inspections and services for all covered heating boilers.

Please note that boilers in the New Muon Lab (NML) and Central Utility Building (CUB) facilities will require boilermakers to disassemble, clean, and reassemble two boilers at each location. Once cleaning is complete, a service technician will be needed to tune the boilers and return them to service.

PM services shall include, but are not limited to (detailed PM requirements are listed in Attachments 1-4):

• Visual inspection of boiler systems, components, and controls

• Inspection for leaks, corrosion, and wear
