CORDEK'S STATE-of-the-art CADCAM technology was put through its paces on the double curvature formwork concrete roof of the new visitor centre at the Cliffs of Moher on the west coast of Ireland recently.
The structure was designed by Arup and is being built by contractor Rohcon. The centre sits in the hillside and will be landscaped to help minimise the visual impact of the building.
The internal concrete nish is textured to replicate the local Liscannor rock. This effect has been achieved using rubber mats with the imprint of the rock.
Cordek created a full threedimensional digital model of the roof and then broke it down into a series of building blocks, which were accurately machined out of expanded polystyrene, using CADCAM technology. This provided the formwork on site.
All formwork units remained fully intact following the striking of the 750mm thick domed roof slab, which will allow the polystyrene to be reused as void formers, saving weight on backll.
