Hays Galleria-Counting House/Air Handling unit replacement

This project involved the de-commissioning and removal of three large AHU’s, two chillers and all associated plant such as pumps, pipework, valves, trace heating and insulation, form the roof plant areas of the east & west wings. The electrical control panels and BMS were all removed and replaced for new.

The AHU’s were positioned externally on a purpose built roof top plant area. Due to the needs of the building the plant required to be operational throughout the works and need to be staged to ensure ventilation was provided to the tenant floors. New DX cooling was installed along with the existing LTHW pipe work being reinstated to new coils in the AHU’s.

Works were successfully carried out over 4 staged weekends including road closers to Tooley street.
