Suburban Rail Loop East Project TBMs arrive

Two CREG TBMs, a little over 7m in diameter, have arrived in Melbourne ahead of the start of tunnelling on the city’s Suburban Rail Loop (SRL) East later this year. The machines are currently being assembled by the section contractor, the Terra Verde Joint Venture, at the Burwood site, where they will be lowered in sections into the launch shaft. As works progress, the site is being upgraded, including the construction of two acoustic sheds to minimise impacts on nearby residents. Supporting infrastructure is also taking shape. This includes a conveyor system to remove excavated material from the tunnels, as well as power connections installed between the Sinnott Street network support facility and the main construction site. Work is advancing on a second TBM launch site, from which machines will later bore towards Box Hill. Crews are also developing the underground station box, with concrete support walls under construction and bulk excavation scheduled to begin in mid-2026. Webuild is leading the joint venture with a 33.5% stake in the €1bn contract. Its partners include GS E&C of South Korea and Bouygues Construction Australia of France’s Bouygues. Commissioned by Suburban Rail Loop Authority, the joint venture’s contract entails the excavation of two parallel tunnels for nearly 10km between the future stations of Box Hill and Glen Waverley, the creation of 39 cross passages between them; two station boxes, two TBM launch sites, and one intervention and ventilation shaft. Construction activity is ramping up across SRL East, employing more than 3,000 people. The line is scheduled to open to passengers in 2035.
