Funkturm (Radio Tower) Autobahn Interchange

Big Open BIM

Reconstruction of the Heavily Congested Motorway Interchange

The Funkturm (Radio Tower) autobahn interchange in Berlin links the two autobahns A100 and A115 in the city centre and is one of the busiest autobahn junctions in Germany with an average traffic volume of up to 230,000 vehicles/24 hours. The aim of the reconstruction project is its complete renewal to optimise handling of high traffic volumes by unbundling and reducing the number of junctions to the downstream inner-city network of the A100.

The urban location, involving the connection to the Messe Berlin (Berlin ExpoCenterCity) and neighbouring railway facilities, residential areas and gardens, listed buildings and archaeological monuments, results in a large number of affected areas. During construction work, traffic flow must be maintained as far as possible.


Big Open BIM: Model-based Design Process

Within the scope of this project, Schüssler-Plan aimed at applying an integrated solution throughout. In consultation with the client, it was therefore agreed to use Big open BIM as the sole design and control method. The aim is to merge the planning of different disciplines in a common model.

The use of Big open BIM permits Schüssler-Plan to achieve continuous and open BIM integration. Besides integrating the road and rail transport systems, it is also possible to integrate about 20 other disciplines. These include traffic performance, environmental and acoustic planning approaches and information on air pollution, explosive ordnance surveys and architectural supervision.

Software Strategies

To achieve optimum utilisation, Schüssler-Plan supplemented the IFC format as an interface to create coordination models in the infrastructure sector with other formats. The most important include:

  • LandXML for axes, gradients and cross-sections
  • Orthophotos
  • Point clouds
  • GIS formats, e.g. GeoJSON

Each of the technical models are either created directly as BIM models or, as often the case with technical disciplines, they are transferred to BIM models.

Plan-it CDE Managementsystem 

To optimise the coordination of all existing project data, Schüssler-Plan continued development of the in-house CDE management system Plan-it and introduced the software within the company. Plan-it acts as a common platform between Schüssler-Plan and its clients for model, design and documentation management as well as to coordinate review and approval processes and visualise workflows. The CDE makes a distinction between two organisational areas:

  • Folder structure with free data entry, e.g. for as-built documents, organisational files such as minutes etc.
  • Metadata including naming conventions for models, derived designs and data drops

By systematic further development, Schüssler-Plan implemented the concept of central task management in such a way that all tasks are bundled in one place and clearly displayed.
