Kopenhagen, Denemark

Project description

Construction of the world’s longest immersed tunnel has begun. The 18 km-long combined road and rail tunnel between Germany and Denmark will be 9 metres high and 43 metres wide and will promote trade and tourism in northern Europe. A factory is being built on the Danish side for the 200-metre-long precast concrete tunnel elements, which will be immersed to form the permanent link between Denmark’s Lolland Falster region and the German state of Schleswig-Holstein. The project will employ 2,000 workers at the peak of operations. This new infrastructure facility, one of the most important projects under construction in Europe, will reduce the travel time between the German and Danish coasts to just seven minutes by train and 10 minutes by car, instead of the current travel time of an hour by ferry or a 160-km diversions by car. the project is expected to be completed in mid-2029.

Our approach

Infranea was involved during the tender phase of the project, focusing on BIM, Systems Engineering and Visualisations on behalf of the Fehmarn Link Contractors (FLC) contractor consortium, consisting of VINCI Construction Grands Projets, Per Aarsleff Holding A/S, Soletanche Bachy International, CFE, Dredging International NV, Wayss & Freytag Ingenieurbau, Max Bögl Stiftung & Co, BAM Infra and BAM International. Consultant: COWI.

Integral project management (IPB) is a means of controlling risks and demonstrating that what has been asked for is made. From the perspective of integral responsibility, applying Systems Engineering is therefore a must. Supporting these processes, an information and configuration management process was worked out, which laid the foundation for the data or information model of the information system that would be implemented after award to support the project processes (think Configuration Management Database, Document Management, Relatics, etc.). This entire information system was designed in such a way that we were going to work from the ‘single source of truth’ (SSOT) principle.

Through the centralised management of all data and information, the system was also going to be the central point of quality control within the project. Through user-friendly approval procedures, products such as 3D discipline models and the BIM would be reviewed and released.

To support the project approach and anticipated innovations, 3 animation films were also made during the tender. One concerning the logistics of the construction site, one around the robust production and logistics process of the tunnel elements and finally an animation concerning the immersion process of the elements. A compilation of these films is shown below.

Project Budget


Besides the risk-driven BIM approach, the animations we produced received high praise. During the tender, they visually supported the elaboration of a number of optimisations in the construction process but also in the implementation of innovations. The animations proved very valuable during the tender phase of the project and were distinctive in the communication
