In the increasingly complex world of construction, the integration of Building Information Modeling (BIM) has transformed how projects are approached, especially in mass timber construction. Our latest technical exploration dives into how expert BIM management, along with the precision of timber engineering, revolutionizes the execution of large-scale projects. Featuring a detailed video demonstration, we show the seamless merging of various 3d IFC models—from mass timber to steel, concrete, and mechanical systems—and the critical process of clash detection.
