Developed to meet and exceed ‘F34’ Structural Hardwood Standards for marine infrastructure (AS4997) and timber structures (AS5100.9), BAC has engineered an advanced composite fibre replacement brace, that meets or exceeds the integrity of the hardwood it will replace. The RSS profile was developed to retrofit where existing timber braces had been. The UAS and EAS profiles eliminate the need for crush tubes or additional hardware required in the RSS

profile, for certain applications.

 

RHS braces are sized to retrofit to the existing spaces that had been machined into the piers. All profiles are installed, usually by two to three men, from a floating work platform under the bridge or wharf structures, whilst they are still in use.

 

Installation:

 

Requiring no heavy lifting, winching or additional tooling beyond common hand tools, rehabilitation can be carried out without any interruption to vehicular or pedestrian traffic... even under active crane wharf applications. RHS braces are sized to retrofit to the existing checks in the piers. All profiles are installed, from a floating work platform under the bridge or wharf structures, whilst they are still in use.

​

A New Zealand company, Divepro Ltd, approached BAC Technologies for a lighter & stronger/stiffer bracing to replace hard to source hardwood. The key driver for Divepro was to minimise the need for heavy lifting equipment & tools. This obviously makes the workplace much safer & reduces physical work for our diving & labour teams.

​

“We install to AS 1720 (Timber Structures) and AS 5100.9 (Bridge Design) and the retrofit of the FutureBraceTM required less manpower using just basic hand tools, working from our floating work platform, and all without taking the wharf out of service”.
