Airport Central Community Zone
The construction site for the Airport Central Station has been established directly south of the Perth Airport control tower.
Both TBMs, which underwent a month-long maintenance program after breaking through into the station box in May, have left Airport Central Station to make room for development of site infrastructure.
In-ground services such as fire, water, sewer and storm water have been installed, tested and backfilled around the station.
Columns to support the different levels within the station box are almost finished with the final one now under construction. Construction of the elevator pit has commenced, as has construction of the elevated walkway which will be part of the main station entry portal.
A milestone was reached in early October with the completion of the first staircase for the station.
In progress is work on the ring beams for the eastern end of the station box. These are circular concrete structures connecting the tunnel segments and diaphragm walls, providing a waterproof seal at the tunnel entry and exit. The first concrete pour is currently curing.
