Event overview

The Cross River Rail project is a new 10.2 km rail line in Brisbane comprising 5.9 km of twin running tunnels and four new underground stations at Boggo Road, Woolloongabba, Albert Street and Roma Street. This presentation describes the wide range of ground conditions encountered, and how they required the consideration of geotechnical variability and uncertainty during design, and verification of conditions during construction. It describes the approaches adopted during design and construction to manage some of the more challenging ground conditions
