Abstract: For BIM design of complex engineering projects, collision inspection is one of the important links, and its execution effect directly affects the overall progress of the project. For large consulting and design enterprises, the management of multi-professional, cross-platform collision inspection has been a hot spot of research. This paper presents a collision check management method based on Navisworks+MySQL. Users select three methods to check the three-dimensional design model based on Navisworks platform, including collision check, incremental collision and collision synthesis, according to their work responsibilities and different application scenarios. MySQL database is used to record collision reports and user operation process. This method can effectively improve the efficiency of collision detection for multi-professional, multi-platform and multi-stage 3D models.
