Detailed design to rehabilitate eroded blast wall embankments at the Mount Stuart Training Area, improving long-term stability and maintaining Defence infrastructure.

Project Overview

Civil IQ was engaged to prepare the detailed rehabilitation design for three existing blast wall embankments at the Mount Stuart Training Area in Townsville. Ongoing erosion within the backfill zones had reduced long-term stability, requiring practical engineering solutions that satisfied Defence standards while extending the service life of the structures.

The project included site assessment, detailed earthworks design, preparation of bill of quantities and RPEQ certification. Rehabilitation measures incorporated engineered embankment profiles, erosion protection and geogrid reinforcement to improve stability while also addressing the impacts of burrowing animals within the embankments.
