SCOPE OF WORK A. Reference 2.02A. B. The extent of ground heat exchanger work is indicated on the drawings and schedules, and by requirements of this section. The closed-loop ground heat exchanger consists of heat fusion joined high density polyethylene piping, to couple to the extended range water-source heat pump units to provide an ISO/ARI/ASHRAE 13256-1 (water/air) and ISO/ARI/ASHRAE 13256-2 (water/water) ground source closed-loop heat pump system. Extended range for the ISO/ARI/ASHRAE 13256-1/2 is defined for testing purposes as 32_F EWT for heating and 77_F EWT for cooling. Any extended range heat pump considered for this application have performance tables detailing total cooling and heating capacity, heat rejection (cooling), heat absorption (heating), kw consumed and EER/COP in 10_F EWT increments, from 20_F to 110/120_F source water temperature. For each 10_F EWT increment, performance values shall be provided at three supply water flow rates with corresponding pressure drop data through the coaxial heat exchanger of the heat pump. Water source heat pumps intended for open loop and boiler/chiller systems, which are rated at narrower EWT ranges on the ISO/ARI 13256-1/2 specification, are unacceptable. INTENT These Specifications are intended to define the contractor's Scope of Work, establish the quality and safety requirements, and set general precautions to protect further construction of the project. Incidental items not specified therein or not shown on the drawings but which are and necessary to complete the work shall be furnished by the contractor in the best available quality. WORK COMPLETED BY OTHERS Any and all work not directly relating to the installation of the Closed-Loop Ground Heat Exchanger, as described in these Specifications and Drawings, shall be provided. The location of the Closed-Loop Ground Heat Exchanger connection to the building heat pump system and the Terminal Point of Piping is shown on the drawing, or as defined by Mechanical Engineer. Refer to drawings.
