Self climbing formwork is helping a suspension bridge across Norway’s Hardangerfjord toward becoming the bridge with one of the world’s longest individual spans at 1.3km.
Main contractor Veidekke is using Harsco’s Manto system to form walls, link beams and hoists on the 1.3km bridge. Veidekke said the formwork is helping to overcome a number of challenges on the project including accommodating the changing dimensions of the bridge pylons as they rise, and coping with high winds at the site.
The steeply sloping sides of the 500m deep fjord mean that the bridge towers must be built adjacent to steep 1.2km high mountain sides, which also require the road to enter tunnels as soon as it leaves the bridge.
The bridge opening is scheduled for 2013.
