FV 505 Skaeveland - Foss Eikeland / Brunnholen Bridge

Sandnes, Norway

By spanning 250 metres, the Brunnholen Bridge is a key feature of the Sandnes bypass south of Stavanger. Since its completion, it has been the four-lane motorway link between Highway 44 Skjaeveland and the E39 Brastein. Incremental launching was the method of choice for construction of this viaduct. Sections up to 34 metres long were constructed in the casting yard and launched incrementally over the bridge piers after the concrete had hardened. Time savings are a big advantage of this method of bridge-building. On this project work proceeded on both bridge structures at the same time.

Herausforderung:
• safe and economical formwork solution for incrementally launched bridge-building
• very tight 300-metre radius of the bridge's curvature

Lösung:
Complete solution from Doka and experienced bridge-building partners, including cantilever carriage, casting yard, formwork for piers, foundations, platforms and outer parapets
