From wasteland to world-class centre: Barangaroo South, Sydney, Australia

Barangaroo South is a A$6 billion (£4 billion) transformation of a former container port in Sydney, Australia, into a business, residential and leisure precinct. Due for completion in 2020, it features three commercial towers up to 49 storeys providing more than 490 000 m2 of gross floor area. It is set to become one of Australia's first large carbon dioxide-neutral developments. This paper provides an overview of the civil engineering challenges facing the project and the innovative solutions adopted, including remediation of past contamination, basement retention and foundation construction in reclaimed land, groundwater control, design of foundations and transfer structures over the proposed rail tunnels, and superstructure design.
