The Alexandria City Hall chilled water plant consists of two 150-ton centrifugal chillers. Both chillers are currently non-operational, with a rental chiller temporarily providing chilled water to the building. The existing cooling tower has reached its expected useful life. Replacement is proposed under this program of improvements. The condenser water piping associated with the cooling tower, located on the roof, is also in poor condition and is proposed to be replaced. The condenser water pumps and building chilled water pumps are outdated and proposed to be replaced. The scope includes demolishing the abandoned cooling tower, chillers, pumps, and piping; installing two new 180-ton air-cooled chillers; replacing the chilled water pumps; extending permanent power; and implementing a new controls package. The selected Consultant must have a comprehensive, professional design knowledge of HVAC systems and state codes, as well as any related building systems.
