Artificial ground freezing was used to enable the construction of three tunnel to tunnel cross passages for the Forrestfield-Airport Link project beneath Perth Airport Airside Land, in permeable soft ground. The technology had never been used before in Australia to such a scale. The combination of ground freezing and cross passage construction within local Ascot and Osborne Formations beneath taxiways and adjacent to runways presented challenges that were overcome by the project team. Some of these challenges were unique to Perth geology while others related to the interaction between cross passage construction and frozen soil.
