Forrestfield-Airport Link hits new milestone

Forrestfield-Airport Link’s tunnel boring machines (TBM) have now completed 70 per cent of the tunnelling works.

TMB Grace has now tunnelled more than 5.6 km and installed more than 3,300 rings, while TBM Sandy has tunnelled more than 4.8 km and 2,800 rings following relaunch after achieving breakthrough at Redcliffe Station in July.

At the Redcliffe location, temporary tunnel segments that helped guide the TBM into the station are being dismantled in preparation for platform and station works.

The next stage has now begun for the project following the completion of the Forrestfield to Redcliffe tunnelling, with tunnel fit-out beginning.

Almost a kilometre of the first section of the infill base slab has been constructed with an extra long drainage pipe and close to 500 m3 of concrete laid.

TMB Grace will now begin tunnelling underneath the Tonkin Highway road reserve in Ascot.
