After spending five weeks at Redcliffe Station, where she underwent scheduled maintenance and had her screw conveyor replaced, TBM Sands is now on her way to Bayswater Junction. This last leg of her tunnelling journey is approximately 2.6km long and the TBM will be installing more than 1600 rings before resurfacing.

Our project recently received the 2019 Concrete Institute of Australia (WA) Award for Excellence in the Technology and Innovation Category. Award judges said the team had gone “well and truly above and beyond what is the norm” in the production of tunnel segments for the Forrestfield-Airport Link. More than 54,000 segments were produced at a custom warehouse in Forrestfield, and our two TBMs have already installed more than 30,000 of the segments to form our two tunnels.
