1. PROJECT INFORMATION:

A. PROJECT NUMBER: 1067228

B. PROJECT TITLE: Repair Replace Live Front and Unfused Transformer

FY20

C. PROJECT LOCATION: Cannon Air Force Base (CAFB), New Mexico

2. DESCRIPTION OF PROJECT:

A. PROJECT BACKGROUND: The live front transformers and unfused transformers range between 30 and 50 years old and pose serious safety concerns. The requirements for electrical safety have become more stringent and the UFC 3-560- 01, Electrical Safety, O&M, requirements for arc-flash protection make live-front transformers even more difficult to work around. The replacement of the live-front and unfused transformers is needed for the safety of electricians as well as the function of the electrical systems.

CAFB is seeking proposals to replace 10 live-front and unfused transformers with the option to bid on 6 additional transformers (See Appendix). The live-front and unfused transformers will be replaced with modern dead front transformers.

These outdated transformers experience regular failures due to their age and exposure to the elements. The transformers also pose a serious safety issue to personnel on base. Open conductors with no shielding at 7200 volts per phase in an accessible box could potentially cause serious harm to anyone doing maintenance on the transformers. In order to prevent injury, the transformers must be shut down before work can be performed which shuts down power of up to 1/10th of the base.

The Contractor shall execute the project as shown in this SOW. The transformer list and location map can be found in Appendices.

3. GENERAL PROVISIONS:

A. The Contractor shall supply all labor, materials, transportation, equipment, and supervision to provide a complete, finished, functional product meeting CAFB Specifications. The Contractor shall include information on each type of equipment
