Transfield Services awarded Duratec a contract to provide a technical condition survey on a jetty at Port Denison.


Port Denison, a popular mid-west holiday and fishing destination, is 360kms north of Perth and close to the town of Dongara. The boat harbour was originally constructed in 1979 and is used for commercial and recreational boating.

An additional boat mooring jetty, constructed in 2000, comprised of reinforced concrete that is demonstrating some tell-tale signs of corrosion of the reinforcement by visible cracking and spalling.

Duratec conducted an investigative survey of the jetty providing a comprehensive technical report detailing remediation strategies that are fit-for-purpose and cost effective.


  • Most of the technical survey was completed from a boat by one of Duratec’s Civil Engineers.
  • Prevailing wind and weather provided challenging conditions.
  • The client received a formal report which clearly explained the issues on the jetty and how they may be addressed to extend its life.
