RRX Rhine-Ruhr Express

One Project. Many Companies. One Model.

© Kompetenzcenter Marketing NRW (KCM)

The RRX is currently the largest rail infrastructure project in the state of North Rhine-Westphalia. The project is the response to the mobility requirements in the Rhine-Ruhr region and creates a new rail connection for passengers between Cologne and Dortmund with a frequency of every 15 minutes. The design of the RRX is intended as a pilot project for the use of BIM in large infrastructure projects and prepares its widespread application.

Schüßler-Plan is commissioned to carry out the building construction and structural design for over 100 civil engineering structures and four stations on a section approximately 26 km long. Schüssler-Plan is lead manager of the RRX working group and supports DB Netz AG in introducing BIM as an industry-wide standard.

The special challenge is to include the new structures in the existing network. Schüssler-Plan uses BIM to accurately record the existing infrastructures and design all aspects of the planned construction project in a model that meets the exact requirements of our client.

In addition to generating as-built models and 3D models for the design, BIM allows the accurate derivation of 2D designs as well as quantity and cost calculations. In addition, the successive construction phase sequence is simulated in BIM and individual elements of a structure can be visualised. The various trades are combined in an overall model and can then be coordinated and checked for spatial collisions.

In response to delays and cost increases in major construction projects, Schüßler-Plan is also evaluating BIM with regard to the improved planning of workflows by testing the following BIM applications:

  • Generation of a cross-trade 3D coordination model.
  • Centralised planning coordination incl. 3D and 4D collision checks.
  • Process optimisation by applying object-based quantity surveying and linking the 3D model to schedules and cost plans.
  • Support for the contract awarding process by the semi-automated generation of service specifications.
  • Model-based land acquisition register, ramp-up cost curve, etc.
  • Drafting LOI content for DB Netz AG and generating a parts library.

Testing tomorrow’s standards today

The vision of establishing BIM as the future standard in transport infrastructure construction is supported by the step-by-step plan for the introduction of the BIM methodology in rail construction by the Federal Ministry of Transport and Digital Infrastructure (Bundesministerium für Verkehr und digitale Infrastruktur). Starting in 2020, this plan envisages the award of infrastructure projects across the board to companies that use BIM. As a pilot project, the RRX acts as a test of BIM and provides DB Netz AG and Schüssler-Plan with valuable insights for future practices. The aim is to develop standards and procedures to ensure collegial and productive collaboration between the stakeholders involved. Schüssler-Plan is already working on the basic principles that will shape this future.
