A one-of-a-kind maintenance unit built by Farra Engineering Ltd is on its way to the top ofka new commercial building in Sydney.
The steel unit, which took a year to design and construct, will allow contractors to put the finishing touches to the 34-storey building in George St and will be used for cleaning the windows of the block.
Farra Engineering chief executive John Whitaker said the company had supplied maintenance units to the burgeoning Sydney construction market for several years, but the latest model was unique.
Designed to be hidden from sight when not in use, the unit was able to climb up an incline and move along its 500m track around the perimeter of the roof, and was also able to navigate its cage over glass structures.
The company's design and construction expertise meant it was able to supply most of the units for new buildings in Sydney. It charged more than $A1 million for this maintenance unit.
The maintenance unit is expected to arrive in Sydney next week.
