Project Background:
Auckland is growing at an unprecedented pace. 1.7 million people currently live in Auckland, and it is expected that over the next 30 years this could grow rapidly.
With population growth, comes the growing demand for fresh water. To meet the needs of the fast-expanding region, Watercare have invested $5.5 billion in water over the next 10 years.
The 34 million Pukekohe East Reservoir Project is the latest and biggest new reservoir Watercare has built in 25 years. With a diameter of 80m and height of 12m, this is a project of great significance carried out by Watercare and Fulton Hogan.
Moddex were contracted by Fulton Hogan to supply handrails to the perimeter of the reservoir, central valve chamber, external and internal stairs.
Why was Moddex selected?
The Moddex system presented obvious benefits:
- 100% compliance guaranteed with a pre-engineered, pre-configured handrail system, complete with a PS1.
- Cost-effective both in terms of materials and quick installation turnaround times.
- Watercare requirement is for the handrails to be HDG-600+ for corrosion resistance which moddex were able to meet.
- Modular systems reduced the potential for water contamination – being no-weld, they eradicate the need for hot works and associated safety hazards of grinding, welding and creating sparks in a highly-flammable environment.
Working in collaboration with Fulton Hogan, Moddex scoped the requirements and put forward a recommendation as to what type of handrail system best suited the application. Having worked on other Watercare projects in the past like the Pukekohe Wastewater Treatment Plant, Moddex were familiar with the Watercare requirements. The Moddex configurations used to complete the design were:
From here Moddex modelled our handrail off the structural steel drawings, which included detailing in the hole positional for the structural steel suppliers to drill. These were then checked off against site dimension to ensure a perfect fit on site. Our client received everything perfectly cut to length, in kit-form, ready for a quick and easy installation.
