Barangaroo South Development, Sydney

Frances Badelow

At Barangaroo South on Sydney’s Central Business District waterfront, Lend Lease is working with the New South Wales Government on the $6 billion transformation of a former container port into a thriving business, residential and leisure precinct. The vision is that Barangaroo South will enhance Sydney’s position as an internationally appealing, globally competitive, environmentally sustainable city. The development will be Australia’s first large‐scale carbon neutral precinct.

Barangaroo South will feature three commercial towers ranging in height from 39 to 49 storeys, with large, highly flexible floor‐plates and sharing a common, two level basement to be retained around it’s perimeter by an approximately 770 m long diaphragm wall, socketed into Sydney sandstone.
This presentation outlines some of the geotechnical challenges facing the project and the solutions adopted, including basement retention and foundation construction in reclaimed land, difficulties associated with old seawalls and buried wharf structures, groundwater control and design of foundations and retention systems, which in some locations are over the proposed future Sydney Metro tunnels.
