In any construction project, clashes can lead to costly delays and rework. Understanding the three main types of clashes—Hard Clash, Soft Clash, and Work-Flow Clash—can
help avoid these issues early on. A hard clash occurs when two components physically intersect, such as a pipe passing through a beam. A soft clash doesn't involve direct contact but breaks spacing or safety guidelines, creating future risks. Work-flow clashes arise from scheduling mismatches between teams, causing coordination problems. Using BIM (Building Information Modeling) is the best way to identify and resolve these clashes before they affect the site. BIM tools, like 3D modeling and BIM 4D, help teams detect and fix issues in the planning phase—saving time, cost, and effort.
