In this research, the automated system for 3D modeling and stability evaluation of caisson was developed. It is possible to build a BIM model while examining the stability of the structures to improve the practical use of BIM technology. This study analyzed industry cases and guidelines for caisson stability evaluation and BIM-based modeling. As a result, the data for calculating the stability evaluation of caisson as well as the modeling parameters were derived. In particular, the automated system for 3D modeling, which reflects more than 30 parameters, allows for BIM models for various types of the caisson, such as open-cell caisson, open-cell caisson with uneven, slit caisson, slit caisson with uneven, and curved caisson. The study tested the proposed system using case studies and found that it helps not only to automate the BIM model with various caisson types as parameters but also to make partial shape changes accessible. The study also confirmed that the stability evaluation can be quickly carried out with shapes changed. Finally, the study results suggest that the proposed method should complete the task seven times as fast as the conventional work method.
