SRL bidder

Victoria’s Suburban Rail Loop (SRL) has announced Terra Verde has the preferred bidder for the second SRL East tunnelling contract.

The global consortium of WeBuild S.p.A, GS Engineering and Construction Australia and Bouygues Construction Australia is set to build the 10km of twin tunnels between Glen Waverley and Box Hill.

The consortium has experience across Victoria and overseas, including the Metro Tunnel Project, North East Link, the Forrestfield-Airport Link in Perth and Copenhagen’s Cityringen Metro.

The Tunnels North contract will be awarded later this year, with detailed negotiations now underway.

This significant milestone follows the award of the Tunnels South contract last year, to Suburban Connect – for tunnelling between Cheltenham and Glen Waverley.

Suburban Connect has commenced ground investigations, ahead of the start of tunnelling in 2026.

The Linewide package to build the fleet of SRL trains, fit out the tunnels, install signalling, and operate and maintain the network will be awarded next year.Two contracts to build the six new underground stations will also be awarded from 2026.

The SRL is anticipated to deliver more public transport and housing options, with a long-term vision for 70,000 more homes and 230,000 extra jobs in the areas around the six SRL East stations.
