Overview:  

​

   Airportlink M7 is a $5 billion toll road tunnel infrastructure project that was recently completed in Brisbane. The project was one of the most complex tunnel construction projects in the world. The project was brought to a halt when the jacking box encountered unexpected concrete structures. 

 

Services provided: 

​

Perfect Shafts International was engaged to remove the concrete structures that had halted the progress of the critical jacked box tunnel, located six metres beneath Queensland Rail’s northbound railway system.

​

The project was in a very sensitive area, in the heart of Brisbane. The concrete which required removal was 17 metres in length. Our experienced team, along with our specialised rock breaking techniques, completed the project on time and under budget.
