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 now under construction and stair shafts spanning between the elevated walkway and concourse levels are almost completed following the installation of precast stair flights.
Up next on the schedule are 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.
