Metro Tunnel hits tunnelling milestone

The Metro Tunnel tunnelling team at Domain Precinct, Melbourne said it has “hit the ground running” in 2021.

Metro Tunnel said major construction is continuing in Domain at the site of the future Anzac Station in its most recent tunnelling update report.

In a key milestone for the project, tunnel boring machine (TBM) Alice has now joined TBM Millie on the drive to the CBD after launching from the Anzac Station site in late January,

Metro Tunnel said TBM Alice has already completed 50 m of permanent tunnel, while TBM Millie has completed a total of 650 m.

“Excavation to the concourse level of the station is continuing under the roof slab, whilst on the St Kilda Road side of the acoustic shed, site crews continue digging to base slab level for the tram interchange station entrance,” the update said.

“On the other side of the shed, works have started to build the Shrine of Remembrance entrance back up from the newly constructed base slab level, with columns and internal walls being installed in preparation for roof construction.”

Metro Tunnel also outlined works that will extend beyond February to provide a long-term lookahead, including the ongoing tunnelling of TBM Millie and TBM Alice, excavated soil removal at the tunnelling support site, south box construction, and the construction of Anzac Station entrances at the Shrine of Remembrance and the tram interchange.
