Falcon Bay Seawall Construction

Falcon Bay Seawall Construction

Project Name: Falcon Bay Seawall Construction

Location: Falcon Bay, Western Australia

Client: City of Mandurah

Project Type: Design and Construct


Leeuwin Civil was engaged by the City of Mandurah to Design and Construct a seawall at Falcon Bay Beach in the Shire of Mandurah.
Design works for the project were undertaken by WML Consultants with structural design analysis performed by marine and ocean experts, BMT JFA Consultants.

The final design included a 65m long sheet-pile-wall, some areas being 6m in depth, with 5m long return flanks. The flanks were topped with concrete ring beams – and a set of stairs, handrails and tactiles installed to provide beach access from the path.
A smaller concrete tie-beam connected the revetment mattress to the wall which was then backfilled and covered with beach sand to provide coastal wall erosion protection.

Construction was mobilised at 100 per cent with all works completed within time and budget constraints.

Scope of Works:

  • design and construction of a 65m long coastal-pile-wall/seawall;
  • installation of a revetment mattress system to protect the wall from erosion and scouring;
  • installation of stairs, handrails and tactiles for beach access.
