In 1999 a development was planned for the historically significant Wales House building in Sydney. An extra floor was required which meant the 915T cupola needed to be raised 3.9m. Since dismantling the cupola was nut possible the decision was made to raise the cupola via the use of hydraulics. The cupola was raised and supported 1.3m a night over three nights.
McMillan Engineering Group designed and manufactured 12 hydraulic cylinders, a hydraulic power unit and a control panel to achieve this engineering feat.
