Renovation of the "Rütihof" level crossing

Application of BIM methods in civil engineering
Renovation of the "Rütihof" level crossing

In this project, no BIM methods were required by the employer, but the planner nevertheless created the BIM 3D construction model without additional effort in order to be able to provide digital data to the contractor. The planner was able to take advantage of the 3D model and deepen his BIM experience. 

This project was also very interesting for us at cadwork, because in this renovation of the "Rütihof" level crossing, the road, work lines, earth movements and track all came together. So we were able to incorporate a lot of practical knowledge into the programme. 

Due to the complexity of the project, we were also able to determine the current situation and show that cadwork is ready for the future of BIM in civil engineering. 

Exciting features of the project:

  • Level crossing (track and road variant)
  • Relocation of the access road "Bipperstrasse" (several connections)
  • Earthmoving for track laying railway (approx. 15'000m3)

Rehabilitation of level crossing "Rütihof" (km 6.561) Section km 6.341 - 6.790 
More detailed information on the application methods

In "2DR strasse" ", all axes (track, road, utilities) were routed and sent to the responsible surveyor via XTR Toporail interface. From this basis and the own routing of the bordering roads, the planner worked out the 3D-construction.

By laying the track, the earth movements were recorded in the cross sections as BIM elements. These were then integrated into the BIM 3D model and digitally forwarded to the contractor for the machines on site (BIM to Field).

The 3D model was exported from "lexocad" via the OBJ interface in order to subsequently create a rendering of the 3D model in Twinmotion. With just a few clicks, anyone can create a professional rendered image in Twinmotion, as well as videos with moving objects.

During the site visit, the extent of the earth movement was particularly visible. The 3D model can show many details, but the spatial perception for the size of the project, only becomes really apparent on the construction site.
