A revolutionary crane solution for Sydney’s iconic ‘sky village’

When internationally renowned architects Rogers Stirk Harbour + Partners teamed up with the Lippmann Partnership to design 8 Chifley by Mirvac, they created the vision for Australia’s first ‘sky village’ concept. The iconic tower design also inadvertently created an engineering challenge that would even test Marr’s unwavering belief that anything is possible.
We work with our clients to find a craneage solution that works – no matter how big or complex the job is.
The architectural design required lifting 12 x 40 tonne steel beams 100 metres above street level onto a construction site within Sydney’s busy CBD – but the real challenge was how to do the heavy lifting when there was nowhere to put the crane.
Mirvac wanted to build a crane that would hug the external face of the building as it climbed but needed an innovative solution to erect the base within the site perimeter. Our answer was a customised offset grillage system that allowed the crane to come out from under the building at the ground-to-fifth storey level and then go up again to a freestanding height of over 60m.
Two years later the job that ‘couldn’t be done’ was completed exactly as Mirvac had imagined it – and Marr had another world first solution to our name.
