Spantech worked with Engineers SASTTI to deliver an innovative design using the Pinkenba 370 panel.
Spantech used the Pinkenba 370 panels’ straight profile for the project. Panels were rolled in continuous lengths, then lifted to the roof in packs and sprung curved as they were laid over the structural supports. To achieve the rounded shape, panels were simply trimmed to follow the existing line of the reservoir.
This solution dramatically reduced the amount of internal structural supports, saving construction time and construction costs. It also significantly improved the ventilation in the reservoir.
Spantech also helped reduce ongoing maintenance costs by rolling the panels from aluminium. This will extend the effective life of the new Campbelltown Reservoir roof from the 50 years required by Sydney Water, to about 80 years.
