ABSTRACT
The topic of BIM is also gaining enormous importance due to public requirements for current and future tenders for infrastructure projects. So far, the specifications, requirements and software programs are mainly based on the subject of structural engineering and infrastructure. But also in the field of geotechnics it is necessary to keep up with the progress and to transfer the ground structure from 2D sections into a 3D ground model.
For this purpose, the borehole profiles have to be implemented and the subsoil layers have to be connected to form a spatial 3D layer model. A multitude of attributes can be assigned to these solids (geotechnical parameters, homogeneous areas, etc.). In the article, several software programs available on the market were tested and the advantages and disadvantages of each were compiled. The 3D ground model can be integrated into the overall BIM model via the open data exchange format IFC, so that 4D or even 5D planning of large projects is possible.
Finally, the opportunities and challenges of BIM in geotechnics are explained and discussed using project examples from practice.
