Project Location:

This project is located at the Lake Mead National Recreation Area.

A. The requirement is to replace existing Variable Frequency Drives (VFDs) at Katherine

Landing, Callville Bay, Echo Bay, and Cottonwood Cove. Additionally, two spare VFDs for each location will be supplied for shelf stock. Sixteen (16) VFDs total in this package to be installed and sixteen (16) VFDs supplied for shelf stock. A total of thirty-two (32) VFDs in all. The sixteen units for shelf stock will consist of a spare per unit that is installed. Submittals must include VFDs that match or exceed the performance level needed to safely operate the motors listed below. If supplier chooses to submit non-identical or alternative VFDs that they believe meets or exceeds the spec they must provide documentation showing that their submittal will be compatible with existing motors and controls. All installations must be NFPA 70 compliant. The COR may opt to review the submittal prior to order but this is just for quality assurance and in no way absolves the contractor from conforming to the specification on this contract. Work will take place at the following location:

Katherine Landing, AZ developed area.

Callville Bay, NV developed area.

Echo Bay, NV developed area.

Cottonwood Cove, NV developed area

B. General work consists of the following at each site:

1. The new VFDs must be installed one at a time and given a 24-hour test run before installing the second VFD to ensure proper operation and to eliminate any chance of down time for the lift station.
