Piling to start at Melbourne Metro Tunnel station

Melbourne Metro Town Hall Square station

Piling has started for the new Town Hall Station for Melbourne’s AUS$11bn (£6.21bn) Metro Tunnel project.

Piling up to 35m beneath will take place in the shaft created by the demolition of the three-storey car park beneath the site for the new station, with the subsequent removal of around 5,000t of debris from the site.

An acoustic shed will be erected over the City Square site early next year, before 24-hour excavation and tunnelling works starts.

Over the coming months, visitors will be able to watch from the viewing windows as workers and construction equipment, bore huge piles 35m into the ground.

When completed, the new Town Hall Station will be located under Swanston Street, between Flinders Street and Collins Street. The station will include an underground passenger connection to the platforms at Flinders Street Station.

Keller with Intrafor (KIJV), part of Bouygues Construction, was awarded a AUS$200M (£113M) contract for work on the project. The contract includes the construction of the substructure retention walls and foundation piling for five new stations on the proposed twin 9km tunnels. 

Crossrail 2 managing director Michele Dix is currently visiting the AUS$11bn (£6.21bn) Metro Tunnel project to share her experience on complex public transport infrastructure projects.

In May, archaeological digs started on the Town Hall Station site, and in April work started on the diaphragm walls to form the station box for Arden Station, the northern most station on the project.

The entire project is on track to be complete by the end of 2025.
