Joint venture to deliver first major construction for North West Rail Link

Under the $A1.15 billion Tunnel and Station Civil Works contract, the companies will construct twin 15 km tunnels, which will run between Bella Vista and Epping. These will be the longest rail tunnels ever built in Australia.

Four custom-made Tunnel Boring Machines (TBM) will be used to construct the 6 m diameter tunnels, with the first of the TBMs to be in the ground by the end of next year.

The alliance expects to place orders for the TBMs in August 2013. The team is also gearing up for a proactive community engagement effort to limit disruption and inconvenience while providing information on the long term benefits of the project.

Work will start shortly to prepare the three major tunnelling sites at Bella Vista, Showground and Cherrybrook, with contract completion scheduled for first quarter 2017.
