Valuation of the 12 year old Concrete in the Ulkebugt Bridge, Sisimiut, Greenland
The Ulkebugt bridge is a vital connection for the town Sisimiut, as it is the only link between the airport and the town. The bridge is a box girder bridge with one central pillar. Most of the pillar’s concrete surface is exposed to seawater, with a tide variation around 4 meters. In addition to the...
