Danish firm Per Aarslef has won a €21.8M (£18.1M) soil investigation contract for the proposed Fehmarnbelt crossing.
The results from the investigation will help will help determine whether a tunnel or bridge is selected for the Fehmarnbelt crossing between Germany and Denmark.
Per Aarslef will be excavating a test area measuring 40m by 70m at a depth of about 10m, about 1km off the coast of Germany.
The company will install piles and instruments in and near the excavation zone. These will measure and monitor earth movements under various loads which will be created if the tunnel or bridge fixed link is built. The resultant soil behaviour will help Femern determine which type of crossing is most suitable.
Marine engineering firm Fugro is carrying out similar tests on land. Femern is expected to make its selection by the end of the year.
