Yamba Sewage Treatment Plant, NSW

Project Background

Moddex were selected by Haslin Constructions to supply WHS compliant handrails with toeboards for stairs, elevated walkways and platforms for the Yamba Sewerage Treatment Plant. While the design brief nominated traditionally fabricated solutions, our proprietary AlyMag® / Aluminium systems were ultimately selected for modular flexibility, no-weld assembly, advanced corrosion resistance and cost efficiencies.

Why was Moddex product selected?

The Yamba Sewerage Treatment Plant handles large flows of water, wastewater and chemical treatments. With corrosion resistance as a key driver for a quality, long-term solution, Moddex presented technical data on the composition of our AlyMag® range to demonstrate compliance with Australian Standard 1657 and corrosion resistance. Our no-weld construction methods made installation safer on-site streamlining the installation process, enhancing corrosion resistance and eliminating costly site shut-downs, firespotters or hot works permits.

Our systems were delivered off-the-shelf direct to site over three stages in line with the project’s construction phases. With installation required at elevated levels, a prefabricated alternative would have resulted in interruptions to construction and the co-ordination of bulky items via cranes to elevated areas. Delivered and installed in-line with construction phases as required, Haslin Constructions eliminated the cost of temporary fencing while protecting workers through each construction phase.

Moddex delivered quality project support, including on-site measurements to establish accurate order numbers, CAD drawings and installation instructions for seamless project delivery.
