Anzac Station construction update

Major construction is continuing on St Kilda Rd at the site of the new Anzac Station. Construction of the roof slab is nearly complete at the northern box where, over the past few months, more than 1600 tonnes of steel and 4200 cubic metres of concrete has been used. Excavation of the station box continues through the void (or hole) in the station roof. This technique minimises noise and dust impacts for the surrounding community. Underneath the roof, support beam installation is under way to support the site during excavation under St Kilda Rd. Excavation of the northern box will continue until the depth reaches approximately 22 metres deep, then a one-metre base slab will be poured. This concrete slab will support the assembly of the tunnel boring machines. In the southern section of the station, roof slab construction is well underway with steel reinforcement and concrete pours taking place.

While works are underway on St Kilda Rd to build the new station, construction of the tunnelling support site at Edmund Herring Oval is ramping up with civil works nearing completion. Tunnelling in the Domain Precinct will commence following excavation of the station box and the construction of a concrete base slab to support TBM assembly. An acoustic shed will also be built over the site to minimise disruption during 24-7 tunnelling operations. During this time, a bentonite mix (or slurry) from the Edmund Herring Oval site will be transported through fully enclosed pipes to the TBM excavating the twin tunnels, and then sent back through another set of fully enclosed pipes to the support site for treatment. The treatment plant will then separate the spoil (excavated material) from the bentonite where, after separation, the treated bentonite is sent back to the TBM for re-use. Two TBMs, Alice and Millie, will be launched from Anzac Station where they will work their way towards the eastern tunnel entrance in South Yarra. They will then be lifted out of the TBM retrieval shaft and returned to Anzac Station to continue their journey towards the CBD.
