This is a design-build project specification document for the installation of a 180 kW DC electric vehicle charging station at Grand Vista Hotel, located at 11597 Scott Highway, Helenwood, Tennessee 37755. The project involves the installation of two ABB Terra 184 dual-port CCS DC fast chargers, providing a total of 360 kW capacity with all four ports capable of charging simultaneously. The scope of work encompasses a complete design-build delivery model requiring the contractor to perform site surveys, geotechnical investigations, and provide a full professional engineer-sealed design package from a Tennessee-licensed engineer. The project includes utility coordination with Plateau Electric Cooperative for service application and capacity verification of the existing 500 kVA pole-mounted transformer, along with installation of a new utility pole, metering infrastructure, and all associated electrical distribution components. Civil work comprises four EV parking stalls (three standard and one ADA-accessible with designated access aisle), concrete charger slab foundations, steel bollards, site trenching, asphalt work, and accessible routes. The anticipated construction period is March 1 through April 30, 2027. All permits, inspections, local authority approvals, and Tennessee 811 locates are the contractor's responsibility. The project requires phased construction to maintain active hotel operations, guest access, fire lane availability, and coordination of work hours with the site host.

The contract is structured as a fixed-price lump sum arrangement with 10% retainage. Contractor qualifications must include a Tennessee State Electrical License and EVITP certification. The deliverables include commissioning and testing of every charging port, connection to the owner's network and OCPP 2.0.1 services, comprehensive EV signage and site finishing, electrical labeling, and emergency disconnect capability. The contractor must provide a five-year warranty, a five-year operations and maintenance plan including quarterly preventive maintenance and 24/7 remote monitoring, and a five-year service level agreement guaranteeing 97% uptime per port with 24/7 driver support available in English and Spanish. All utility fees and make-ready costs are included within the lump sum price. The charging stations must support CCS1 minimum with NACS-capable equipment welcome, operate on open access protocols, and accept contactless card/RFID and QR code payments.
