In another exciting project milestone, both TBMs have now left Airport Central Station to tunnel the 2.8km towards Redcliffe Station.
A number of construction sites have been created along the project’s 8.5 km route and each site has potential noise and vibration sources.
Before works begin, property condition surveys will be completed on buildings adjacent to construction sites.
Following TBM Grace’s arrival at Airport Central Station on May 8, TBM Sandy also broke though into the station’s underground box late last month.
The two tunnel boring machines for the Forrestfield-Airport Link have now reached Airport Central Station - about a quarter of the way into their 8km journey to Bayswater.
