Whyalla Jetty Project
We are undertaking a design for a new fishing jetty at Whyalla, after the existing jetty was closed last year due to damage and degradation. Part of our scope of works is to present three options for the new jetty construction, which will be:
- Steel piles and superstructure, as Whyalla is a steel producing town. These are to be protected with a marine grade paint system.
- Concrete piles and superstructure, but using high strength marine grade concrete and glass fibre reinforced plastic (GFRP) reinforcement in lieu of normal steel reinforcement. This GFRP is stronger than steel and will not rust, negating the “concrete cancer” problem common in concrete structures in the marine environment. This GFRP is now manufactured in Australia to world-class standard and offers a leading edge of technology.
- Steel piles with composite fibre beams and decking. These are beams and decking manufactured from fibreglass and will not rust. This provides a solution that largely avoids rusting of steel or concrete cancer and should have a much greater maintenance free lifespan. Again, these products are Australian manufactured.
This work is currently in the site investigation and preliminary design phase.
