Right now we continue our work on preparing the tender document and technical support for the Environmental Impact Assessment (EIA) in Denmark and in Germany. This time though, I will follow up on the four main contracts of the Fehmarn belt tunnel project and elaborate on the competitive dialogue described in the prequalification documents. The
