Statement of Work

For Providing and Installing a Complete Generator and Automatic Transfer Switch

System at the Montana Plant Materials Center, Bridger, Montana

BACKGROUND: The United States Department of Agriculture Natural Resources Conservation Service (NRCS) Bridger Plant Materials Center (BPMC), located at 98 South River Road in Bridger, Carbon County, Montana, is a 150-acre research facility and farm located in rural south-central Montana. Weather events and electricity delivery system failures sometimes result in power interruptions at the center. These failures could result in unsafe conditions for employees, possible loss of or damage to public property, and possible loss of important germplasm (plants and seeds). In order to protect these valuable assets, a whole facility generator with self-starting capability is needed.

SCOPE: The BPMC has a requirement for a whole facility generator and automatic transfer switch. The work primarily consists of installing a new generator and automatic transfer switch to fully power a seed cleaning facility, office, greenhouse/headhouse/laboratory, coldframe, well and lawn pumps, and shop during power outages at the BPMC.
