The scope of the work encompassed the maintenance and repairs to approximately 160m of existing limestone retaining wall along the river adjacent to the Kwinana Freeway. This section of wall is adjacent to Judd St, South Perth and supports a Principal Shared Path. The works were broken down into the two following items:

  • Maintenance and repairs to existing limestone block retaining walls and sloped revetments; and
  • Installation of limestone rock toe protection.


Advanteering were able to programme the works around the natural variability of the tides and weather conditions in the marine environment while minimising any environmental issues or impacts associated with works near the Swan River.
