As one of the largest port projects in Australia, the Port Botany Expansion includes a 1.8-km wharf, five berths, 60 hectares of reclaimed land, expanded road access and other elements.


The physical components of the project were of extraordinary scale. They included 22 metre long precast concrete counterfort units that weigh 650 tonnes each. The counterfort units have a base, wall, and buttress to form a composite section. More than 200 counterforts make up the outer retaining wall of the new container terminal and provide a vertical wharf face for ships to berth against.


Delivering Independent Advice

Although the delivery consortium was responsible for its own quality control and systems, the owner engaged WSP to check that the work meets technical, functional, environmental, and durability requirements.


Using our marine engineering and environmental knowledge, we acted independently to verify that the work was carried out according to the owner's requirements.


Adding Value

As project verifier, we worked with the owner and the design and construction consortium that developed the expanded facilities. This project doubled Port Botany’s container capacity. It is now Australia’s largest container port and specialises in trade in manufactured products and bulk liquid imports including petroleum and natural gas.
