A joint venture (JV) between Keller Group and Intrafor – a Bouygues company – has been awarded a A$200 million contract to construct the substructure retention walls and foundation piling for the Melbourne Metro Tunnel Projects’ stations.
The 50:50 Keller Intrafor JV’s work will require two diaphragm wall cutters, four diaphragm wall grabs and up to 12 piling rigs.
Keller and Intrafor have already provided a “significant amount” of early technical advice to optimise design.
Work is expected to start immediately with the majority of it being complete by mid-2019.
Keller CEO Alain Michaelis said: “Our global scale and expertise, in combination with a strong track record of successful work in Melbourne, made us ideally placed to win work on this landmark project.”
The Melbourne Metro Tunnel is a new metro line running through the Melbourne Central Business District that will deliver twin 9km tunnels and five new underground stations.
