This document is Addendum 2 for an HVAC replacement solicitation issued by the West Virginia General Services Division (GSD) for Building 27 Surplus Annex located at 2700 Charles Avenue in Dunbar, West Virginia. The project involves removing and replacing one 2.5 Ton 60,000 BTU Natural Gas, 96% Furnace with a matching Cased Evaporator Coil 2.5 Ton Condensing Unit. The installation requires a new 30-foot copper line set, filter rack, non-programmable thermostat, electrical disconnect, duct connections, duct wrap, condensate drainage system, and placement of the new condenser on a new concrete pad. The furnace must be horizontal and include a concentric vent kit. The contractor will be responsible for all debris removal and disposal of the existing unit.
The solicitation is structured as a lump-sum bid with no alternate pricing options. The contract includes a one-year warranty on labor and requires the manufacturer's warranty on materials. The vendor must provide a full construction schedule within 72 hours of contract award, indicating materials lead times, onsite construction start date, milestones, and completion date. Work is to be performed during standard hours (7:00am to 5:00pm, Monday through Friday), with potential for work outside these hours as approved by the agency.
