Sydney Metro West
2024
As part of its expansion, the City of Sydney is extending its metro train system with underground tunnels and stations. VSL Australia and Keller, as a joint venture, were hired to construct two diaphragm wall shafts that will serve as station boxes. The two companies together designed the associated production plant for steel cages and concrete panel fabrication, as well as equipment for the works onsite.
KVJV developed a custom concrete mix to reduce carbon emissions by minimising cement use and optimised the cage design for the second shaft, halving the number of delivery trips to 288 because more of the smaller, lighter units could be carried on each truck.
