WATCH: Second TBM breaks through in Perth

On 6 July, Forrestfield Airport-Link’s second tunnel boring machine (TBM), known as Sandy, broke through at the Redcliffe site.

Sandy’s 7 m diameter cutter head excavated into Redcliffe Station, the second time the 130 m long machine had surfaced since leaving Forrestfield.

On its journey, the TBM has tunnelled 4.5 km and installed more than 2,750 rings to form Tunnel Two.

Maintenance works began shortly after the machine’s arrival, including the testing of mechanical and electrical equipment, replacing worn cutterhead tools and installing a brand-new screw conveyer.

To celebrate the arrival of Sandy, the project will host a Redcliffe Station Community Information Day on Sunday 28 July, incorporating both an open drop-in information session at the Redcliffe Primary School and a series of bus tours.
