SCOPE OF WORK

ANJO PMIS # 350859A

Replace Underground Electric Andrew Johnson National Historic Site

PROJECT LOCATION

Andrew Johnson National Historic Site, Andrew Johnson Homestead, 209 S Main St, Greeneville, TN 37743

SUMMARY OF WORK

The existing power feed from the aboveground electrical box to the basement of the building is past its service life and must be replaced. Install, using directional drilling, approximately 210 lineal feet of 2.5” HDPE SDR 11 electrical conduit with new conductors (see below for details) from the existing electrical box to the existing main disconnect in the basement. Conduit and conductor installation must meet the requirements of Greeneville Energy Authority (GEA) and the National Electric Code. Also install, using directional drilling, an additional 2” SDR 11 HDPE telecom conduit suitable for running fiber optic cable.

Both conduits will be chased into the basement of the building. Contractor will also be responsible for coordination with electric utility to install a new aboveground electrical box, and to connect and energize the new electric connection (Note that GEA will provide a new above ground electrical box at no cost).

The contractor will be responsible for acquiring any permits from the utility or county for the electrical connection, if required. The contractor will also be responsible for payment of any fees to Greeneville Energy Authority for their services for the electrical connection, and any permit fees, if required.

DEFINITION OF CONTRACT LINE ITEMS

Item No. 1 – Install Electrical Conduit & Conductor and Telecommunications Conduit

This item consists of:

1. All labor, materials and equipment to install electrical conduit and conductor from transformer to main disconnect in basement, including any labor, materials and equipment required for the installation to meet the requirements of Greeneville Energy Authority and the National Electric Code.

2. All labor, materials and equipment to install telecommunications conduit from new pull box adjacent to transformer to inside basement of building.

3. Coordination of electrical connection by the electric utility provider and payment of any fees to electric utility provider. This also includes any permitting required by the utility provider or county to provide the electrical connection.

Measurement for payment will be on a lump sum basis as a single item of work. Payment will be made at the contract lump sum price.

WORK AND PRODUCT REQUIREMENTS

1. GENERAL: All work must meet the requirements of the most recent edition of the National Electric Code and also must meet the requirements of the utility provider, Greeneville Energy Authority (www.mygea.net, Engineering Office: 423-636-6240, Contact: Bronson Dean).

Also included in the attachments are Electrical As Builts of the basement and the One-Line Diagram, as well as a site map showing approximate locations of the transformer and the location where the conduits will need to be chased into the basement of the building. Contractor will need to use the existing building penetration in the basement for electricity (the existing penetration is under the basement slab). If reuse of existing penetration is not feasible, contractor must provide a submittal to the Contracting Officer including the location of the new penetration and the reasons why the existing penetration cannot be reused. This submittal will need to be approved by the Contracting Officer before any work is performed to ensure the new penetration does not affect the historic fabric of the building. A submittal will also need to be provided detailing the proposed location of the penetration for the telecommunications conduit.

For the excavations to chase the conduits into the basement, the Contractor must comply with all applicable federal, state, and local safety regulations, including the Occupational Safety and Health Administration (OSHA) standards set forth in 29 CFR Part 1926, Subpart P – Excavations.

This includes providing the required appropriate protective system, such as shoring.
