Legacy Way is a 4.6 kilometre long road tunnel joining Brisbane’s western suburbs with the Inner City Bypass. While mega-projects such as this are designed and built by consortiums of international companies, Osborn Consulting Engineers has been able to make several contributions to this project.
In this photograph, precast concrete wall panels are being placed under difficult conditions. Typically for work in tunnels, these difficult conditions are caused by lack of access, and co-ordination with many other services. Osborn Consulting developed an innovative pretensioned concrete design for these panels, which minimised their weight and hence their ease of handling.
Osborn Consulting also contributed to design of the lifting and handling equipment for the panels, design of pretensioned concrete ceiling panels, and noise barrier panels in the Legacy Way project.
