Comparison of software applications for the construction of the special model subsoil In the context of Building Information Modeling (BIM), the subsurface is receiving increasing attention. The so‐called special model subsoil, which has to be constructed by a geotechnical ex‐pert, must contain not only the geometrical representation of the relevant soil layers, but also the associated data of the accompanying geotechnical report. In addition to the difficulty of more often than not insufficient specifications regarding information depth and structure by the client, limitations can arise from the software application used for modelling. This work provides a comparison of the construction process of the special model subsoil for a fictional test project using four different and well‐established software applications. The differences found regarding the effort required to obtain a working model, the modelling functionalities and the usefulness of the final special model subsoil as part of the parent BIM‐model are presented. Furthermore, more general aspects such as the level of software support, training materials and integration with other software applications are described and compared. The key differences in the geometrical modelling results are compared using cross‐sections. Based on the experienced gained by this comparison, areas are identified where current software applications are lacking and further development is required. [ABSTRACT FROM AUTHOR]
