About this file
This is an attachments document for a federal contract involving replacement of underground electrical service at the Andrew Johnson National Historic Site located in Greeneville, Tennessee.
The project requires installation of new underground electrical infrastructure to replace existing aboveground service. Key technical requirements include: providing new underground conduits from an existing aboveground electrical box (located in a wooded area near the homestead) to the basement of the historic structure, chasing conduits into the basement at an approximate location to be identified by the Contracting Officer in the field, and installing new disconnect switches, transfer switches, distribution panels, and associated electrical components per the provided electrical drawings. The work must comply with Greenville Electric Authority (GEA) standards for underground electric service, including specific requirements for trench depth (minimum 3 feet), conduit sizing (2-1/2 inch or 3 inch primary conduits with 1 inch communication duct), warning tape installation, coupling support straps, expansion couplings, and elbow specifications. All electrical work must follow the 2002 National Electrical Code. The attachments include site maps with aerial and ground-level photographs marking the electrical box location and conduit chase alignment, detailed electrical as-built drawings showing the basement plan with new work, electrical legend and one-line diagrams, and GEA standard specifications for underground service requirements to structures and trench construction details. All facilities and conduit installation must be completed by GEA or approved contractors, with trench inspections required prior to backfill.
