Construction work on the $4.8bn Airport Link project in Brisbane commenced in December 2007. This major piece of infrastructure involved the construction of a 6.7km long road to Brisbane airport, extension of the existing Northern Busway to Kedron and the upgrading of the existing Airport Roundabout. The 11kms of tunnels require the use of two Tunnel Boring Machines (TBM). All three sections of work were completed by the middle of 2012.

To form the complex intersections along the route, secant pile walls were installed so that cut-and-cover tunnels could be excavated. Bauer also constructed foundation piles for a large number of bridges at the intersections.


Six Bauer BG piling rigs were used to install the piles over the period from May 2009 to June 2010.
