PERFORMANCE WORK STATEMENT

Upgrade ASCO Switchboard and breakers Building 485

TYNDALL AFB FLORIDA

1.0 SCOPE OF WORK

This is an equipment/technology upgrade to the building back-up generator/power system from an antiquated mechanical contact technology to solid state. The system operates the critical generator back up system in Building 485 within the Air Operations Center compound. This requirement includes:

1) Assembly will be built to match physical parameters of the existing system, allowing reuse of conduit and wiring.

2) Remove existing ASCO switchboard assembly

3) Prep area and install new switchboard assembly.

4) Verify existing generator and transfer switch operations are seamlessly integrated to the new switchboard assembly.

5) Provide updated panel layout control drawings showing wiring schematic details for the new switchboard assembly and associated equipment tie in.

6) Provide owner training and familiarization with the features and capabilities of the new switchboard assembly.
