The Existing equipment had reached and of life and required a solution to upgrade the equipment to ensure reliable tenant comfort, the project challenges were significant due to the rooftop plant and existing Air Handling units location which had made replacements unable to be completed via craneage as the reach was simply too far due to a shopping centre extension that had been carried out many years prior.

It was determined the only feasible way forward was to remove and replace the current equipment with a new air-cooled chiller, associated pumps, controls and ancillaries and replace the current refrigerated Air Handling Unit with a new Chilled Water air handling unit, The Existing AHU was to be dismantled and removed by hand with the new AHU to be built on site.
The removal of the rooftop mounted chillers required part dismantling to ensure the maximum weight loading were not exceeded and the design focused on sourcing a suitable air-cooled chiller that did not exceed the weight loading requirements to enable the Heli-Lift to be achieved.
Significant forward planning with stakeholders, local council and the Civil Aviation Safety Authority was required to ensure this project as able to be completed prior to ensuing summer period, works were staged to replace the AHU in the first instance and prepare for the removal and replacement of existing and new chillers with all lifting work completed on a Sunday morning with the building empty and full traffic and public management in place to cordon off the work area and surrounding road.
All works were complete on time and a quality outcome has been achieved which will provide years of trouble-free operation for our client.
