Arup has announced that offshore geotechnical investigations for the development of the Roskilde Fjord Link in Denmark have been successfully completed.
Under the scheme, for which Arup is the main consultant, the Danish Road Authority will build a 9km road link with a 1.4km long bridge over Roskilde Fjord.
According to Arup, the lack of civil works projects of comparable size in the area meant that the ground conditions at the future bridge location were largely unknown so the large scale investigation was vital to the scheme. The company also said that there was a particular lack of information regarding the limestone formation which is expected to be encountered at a variable depth and may represent the competent founding layer for the bridge’s piled foundations.
The site activities include a blend of traditional and innovative investigation methods such as seismic dilatometer tests which enhance the site characterisation and result in a cost-effective geotechnical investigation.
