Merit were contracted to undertake the replacement of the roof mounted chiller plant, air-handling units and associated electrical infrastructure & control systems. The work was undertaken in a number of phases to minimise disruption.
During the works to ensure there was no disruption to the store all services remained live which required Merit to develop temporary bypass distribution systems. Any works which presented a risk of service loss or impacted on traffic in Knightsbridge were undertaken during the night. To reduce the number of crane lifts and hence reduce the time the crane was situated in Knightsbridge, Merit prefabricated the plant into mountable skids creating a limited number of units.
The project also included construction works to refurbish elements of the roof and provide plant screening in keeping with the building and the surrounding area.
