Civic Tower is Australia’s first building to be fully supported on a central lift core without the use of continuous perimeter columns extending down to footing levels. Constructed above Sydney’s Masonic Centre, the innovative structural design features a space frame using post tensioned tie elements and high strength concrete filled tubular steel struts to transfer the 25 story office building perimeter back onto its core.
