Preferred bidder announced for SRL East tunnelling works

The second tunnelling contract for the Suburban Rail Loop East project has been awarded to a global consortium of tunnelling specialists, as works power ahead on the first stage of the Victorian project.

The second tunnelling contract for the Suburban Rail Loop East project has hit a major milestone, with a global consortium of tunnelling specialists being announced as the preferred bidder, as works power ahead on the first stage of the Victorian based project.

The Suburban Rail Loop will transform Victoria – and by 2026, tunnel boring machines will be in the ground and more than 4000 people will be directly working on the project. SRL East will deliver six new underground stations at Cheltenham, Clayton, Monash, Glen Waverley, Burwood and Box Hill.

The successful consortium consists of WeBuild S.p.A, GS Engineering and Construction Australia, and Bouygues Construction Australia – Terra Verde. They will deliver the 10-kilometre northern twin tunnels between Glen Waverley and Box Hill following contract negotiations as part of the second tunnelling package.

The $3.6 billion contract for the first stage of tunnelling was awarded to Suburban Connect in December last year to complete the 16-kilometre southern twin tunnel between Cheltenham and Glen Waverley. Site investigations and preparatory work are currently making way for tunnel boring machines (TBMs) to begin work in 2026.

The Tunnels North contract will be awarded later this year. This stage comprises all tunnelling and station box excavation works on the SRL alignment between Glen Waverley and Box Hill. Two contracts to build the six new underground stations will be awarded from 2026.

The project is backed by an $11.8 billion investment by the Victorian Government and a $2.2 billion investment from the Federal Government.
