The plans are ready and the contracts are signed to connect Germany and Denmark via an 18 kilometre long immersed tunnel. The so called Fehmarnbelt tunnel will be the world's longest of its type for both road and rail. Good preparation and use of the BIM/CAD software of thinkproject should lead to the opening of the tunnel in 2028.
The Fehmarnbelt tunnel is an important part of the European transport network. It provides a much faster connection between Hamburg and Copenhagen. Along with the Øresund fixed link between Copenhagen and Malmö, the Fehmarnbelt link will bring Scandinavia and Central Europe closer together via the so-called North-South corridor. Important for economic and touristic activities. And good to know that the Fehmarnbelt project will be undertaken with the greatest possible respect for nature and the environment. Around 150 internationally renowned biologists, geographers, landscape planners and engineers are involved in the project.
An ambitious construction
The Fehmarnbelt tunnel will comprise a four-lane motorway and two electrified rail tracks. It will replace the ferry link between the German city of Puttgarden and the Danish city of Rødbyhavn. It will take ten minutes to travel from Denmark to Germany by car and seven minutes by train, thereby cutting two hours from the 4h 40m needed to travel by rail between Copenhagen and Hamburg and one hour from the 5h 40m required by road.
Ambitious plans, ambitious software platform
The budget for the total construction of this ambitious tunnel plan DKK 52bn or EUR 6.9 bn. The EU Commission has designated the Fehmarn link as a priority project and has therefore provisionally allocated DKK 1.7bn in support of design costs and DKK 5.3bn for construction costs to the project.
The ambition regarding the plans for the tunnel were the same regarding the BIM software platform they wanted to work with. After an elaborated pitch, Femern A/S awarded thinkproject with this contract. First, due to the completeness of the solution, comprising the following elements:
BIM - Building Information Management
One of the advantages for Femern A/S is that the System architecture is designed as modules to handle different aspects of data management in a Common Data Environment. There are specific modules to keep track of the delivery of design packages (Delivery Management) and to keep track of interdependencies using methods for classification, versioning, data container, packaging and linking (Design Management).
Data management and organisation
The platform is built up out of 'containers' containing three elemental data building blocks: metadata, data files, and logging. The tracking can be done either by being captured as metadata, as an attachment, a reference to another container or a link to an external repository.
BIM and CAD Management
Open design data in IFC or other open formats (e.g. PDF, LandXML) can be managed in parallel with the proprietary files in one container. Viewing of point clouds and support of other types of data like pictures and spatial scannings is included. All BIM/CAD models and respective 2D drawings can be combined in coordination models for review, analyses, and archiving. The interdependencies of the design and controlling data are managed using methods for classification, versioning, data container, packaging, and linking.
The thinkproject environment can support the defined workflows. The user is guided through several steps making it easy to overview the process. Based on the defined metadata for a data file the thinkproject environment can automatically select the applicable reviewers, approvers etc. After initiation of a workflow the first user will get notified.
The System supports a double layered approach for logging and traceability. All actions, workflow progress, actions related to files, i.e. models and documents, are available for the end-user with the right credentials, in an accessible way.
Towards a successful cooperation
We are honoured to be able to contribute to a proper and successful construction of the Fehmarnbelt tunnel in order to let cars and trains drive through the tunnel in 2028. thinkproject your partner in construction intelligence.
