Efficient multidisciplinary coordination is essential to avoid conflicts between building components. While Building Information Modeling (BIM) is widely used for automated clash detection, clash resolution remains largely manual and time-consuming, limiting the effectiveness of current BIM-based coordination workflows.

This research presents a method that makes clash management more effective by using both BIM data and graph theory. The process turns clash data into a network of components and their relationships, allowing clashes to be reviewed as groups instead of individually. With this approach, building elements are ranked by how easily they can be moved, related clashes are grouped, and repetitive conflict patterns are found. This results in a list of elements that can be moved to resolve clashes in each group.

This method can help coordinators focus on the most critical clash groups and reduces redundant design modifications by addressing related clashes collectively. The application of the method in real-world case studies demonstrates its potential to support a more structured and informed BIM-based coordination process. The results show that representing clash relationships using graph models improves the understanding of interdependencies between building systems and supports a more systematic approach to clash resolution.
