Major works on Suburban Rail Loop are another step closer, with international construction companies shortlisted for the tunnelling contracts on SRL East.

SRL East will deliver 26 kilometres of twin tunnels and six brand new underground stations between Cheltenham and Box Hill. Trains will run by 2035, with an end-to-end trip of just 22 minutes.

Initial works on SRL East are already underway in Clayton, and major works have been given the green light following a rigorous Environment Effects Statement (EES) planning process.

Tunnelling begins in 2026, with up to ten tunnel boring machines (TBMs) to be used to carve out the twin tunnels. The tunnelling task will be split into two separate contracts to ensure the work is done as efficiently as possible, minimising disruption to the community. These will be awarded from the shortlist announced.

SRL East has drawn extraordinary interest from the international construction market, with five outstanding bids for the tunnelling work. Three have now been invited to submit a detailed Request for Proposal.

  • CPB Contractors Pty Limited, Ghella Pty Ltd and Acciona Construction Australia Pty Ltd – companies involved in Brisbane’s Cross River Rail, Sydney Metro, Vancouvers’ Broadway Millenium Subway and the Caulfield to Dandenong Level Crossing Removal.
  • John Holland Pty Ltd and Gamuda Berhad trading as Gamuda (Australia) Branch – these companies have experience building Melbourne’s Metro Tunnel, Sydney Metro Northwest Tunnel, Malaysia’s Klang Valley Mass Rapid Transit, and Melbourne’s City Loop
  • Webuild S.p.A and GS Engineering and Construction Australia Pty Ltd – companies with experience in projects including the North East Link tunnels, Copenhagen’s Cityringen and the Middle East and Asia projects.

“This competitive process has been a massive vote of confidence in Suburban Rail Loop – with construction giants from around the world vying to partner with us to deliver this city-shaping project,” says Suburban Rail Loop CEO Frankie Carroll.

The first contract will be awarded next year for twin tunnels between Cheltenham and Glen Waverley. The second is to construct tunnels between Glen Waverley and Box Hill.

Contractors will be required to deliver at least 92 per cent local content (excluding TBMs) – a massive boost for Victoria’s steel and concrete industry.
