General description

In Australia, in northern Sydney, Bouygues Construction Australia is constructing a 9-kilometre, dual three-lane motorway tunnel that will link the M1 and M2 motorways. Taking advantage of the predominately sandstone geology, 17 roadheader machines brought in from the mining industry are used for the excavation. The topographical surveys are performed using a scanner and data is transmitted to the surface via Wi-Fi. The drill holes for the permanent tunnel equipment support anchors in the ceiling are machine-drilled using the in‑house designed Roby 850 robot.
