Suburban Rail Loop has attracted interest from global leaders in tunnelling and construction, with submissions received from 5 world-class bidders to build the twin tunnels for SRL East.

Expressions of Interest (EOIs) have now closed for the 2 tunnelling contracts – the first between Cheltenham and Glen Waverley – the longest tunnelling package in Victoria’s history – and the second between Glen Waverley and Box Hill.

The 5 bidders include companies with track records delivering iconic projects both locally and internationally. They are:

  • Bouygues Construction Australia Pty Ltd
  • CPB Contractors Pty Limited and Ghella Pty Ltd and Acciona Construction Australia Pty Ltd
  • John Holland Pty Ltd and Gamuda Berhad trading as Gamuda (Australia) Branch
  • Samsung C&T Corporation and Hyundai Engineering & Construction Co, Ltd
  • Webuild S.p.A and GS Engineering and Construction Australia Pty Ltd

Three bidders will move through to a Request for Proposal process later this year, and from there, 2 will be awarded tunnelling contracts – the first to be announced next year.

SRL East will deliver twin tunnels from Cheltenham to Box Hill with new underground stations at Cheltenham, Clayton, Monash, Glen Waverley, Burwood and Box Hill. Up to 10 tunnel boring machines (TBMS) will be used in the project, with tunnelling to begin in 2026.

Construction on SRL East kicked off on Thursday 2 June, with the launch of a massive program of initial and early works which will create up to 800 local jobs. As well as utility protections, the Initial and Early works will include road modifications, service relocation and preparation for three sites where the TBMs will be launched.

SRL East will generate up to 8,000 jobs during construction, delivering exciting opportunities and a long pipeline of work for local industry and suppliers.
