Girish Hedge – Project Engineer
Airey Taylor Consulting evaluated the existing 23 year old board-walk sub-structure (also known as the Majestic Board walk) and found it had a 40% mass loss. A design decision was made to replace the existing structure of concrete columns with Glass Fibre Reinforced Polymer (GFRP) to achieve a cost effective, low lifetime maintenance design.
The remaining steel superstructure was replaced with a new easily maintainable ultra high build epoxy paint coated steel structure with GFRP holding down bolts and EPDM gaskets throughout reducing bi-metallic corrosion effects.
This project was the first in Western Australia to utilise GFRP bars in compression members. For more information on the use of GFRP please refer to our ‘Innovations’ page.
