A second TBM has officially begun tunnelling at Forrestfield, as part of the $1.86 billion METRONET Forrestfield-Airport Link project.
Salini Impregilo – NRW Joint Venture will design and build 8km of underground rail tunnels and three new train stations.
Environmental management is a key priority during construction of the Forrestfield-Airport Link. Building the new line underground will reduce the impact to the natural environment, local residents and businesses.
The Forrestfield-Airport Link’s two tunnels will be constructed with 54,000 concrete segments. A Forrestfield warehouse has been transformed into a facility to batch the concrete and create segments to line the two tunnels.
Emergency egress shafts provide safe exit points in the event of an emergency, and access to the Forrestfield Line's twin-bored tunnels for maintenance,
