Base Bid Item: Subject requirement is a design-build construction project to perform repairs to the transformer and electrical equipment in Bldg. No. 339, Dudley Knox Library, at Naval Support Activity Monterey (NSAM). The transformer and electrical equipment which service the library have reached their end of life and are in need of replacement.

The work includes demolition and removal of the existing equipment. The new stepdown transformer, sectionalizing switchgear, and low voltage load center service entrance equipment must be installed outdoors above grade. The contractor shall also provide temporary generator support to Bldg. No. 339 while its existing electrical equipment is being replaced.
