63 Ann Street, Surry Hills

QEG was engaged by Abacus Property Group to deliver a full mechanical services upgrade at 63 Ann Street, a three-level commercial office building in Surry Hills whose 25-year-old R22 air-cooled DX plant had reached end of life. We carried out a condition assessment, prepared the design-and-construct tender documentation, ran the tender and recommended CBR Mechanical, then provided project management and superintendency through construction. The works replaced all four floor-level fan coil units and rooftop condensers with new Temperzone reverse-cycle units, relocated the kitchen condenser to the roof, removed redundant refrigerant pipework from the toilet exhaust duct and introduced a new steel structure to lift the condensers clear of the perimeter wall for proper airflow. Works were staged on a floor-by-floor basis over weekends so that tenants were not displaced.
