On January 2017, Trevi Australia started working for the Forrestfield Airport Link project in Perth, Western Australia.

The project consists of an 8.5 km rail extension that runs through two underground tunnels beneath the Swan River and Perth Airport, providing a much-needed public transport link to the airport and a 20-minute rail journey from Perth’s eastern suburbs to the city.

The works Trevi Australia performed were related to the soil consolidation for the construction of the cross passages for the new underground rail link.

For three cross passages located under the Perth Airport, where restricted access makes other technologies impractical, Artificial Ground Freezing was adopted for the soil consolidation.

Works are currently ongoing and the completion of ground freezing works is expected in the first quarter of the year.
