Retaining Structures –

The underpass incorporated a large extent of retaining walls thus a significant effort was inputted to design the structures to achieve optimum design conditions.

 

Design –

Improvements to the design was cost effective and time efficient. Where a shorter temporary freight rail diversion was incorporated instead of permanently raising the rail alignment.  

​

Existing Structures –

Earthworks were conducted past Goodwood station platform that wasn’t equated within the design and a section of the retaining wall collapsed. To prevent this happening again a thorough investigation was launch prior to excavation.

 

Slab Track-

The slab on the track had void issues. To eliminate the issue, further projects will utilise a standardised construction methodology such as the Outer Harbour Rail Bridge.
