To identify clashes in a project model, which approach is commonly used?

• A. RFI
• B. Riser diagram review
• C. 3D CAD interference check
• D. Finish schedule

Answer: (C)

Clash detection in a project model is typically done with 3D CAD/BIM interference checks. These tools automatically compare the geometry of elements from different disciplines—like architecture, structure, and MEP—to find where things occupy the same space or are too close to each other. The result is a clash report that pinpoints location, the conflicting components, and how severe the clash is, enabling designers to resolve issues before fabrication or construction. An RFI addresses questions about design intent but doesn’t automatically flag spatial conflicts. A riser diagram review looks at vertical routing and system placement, not broad clash detection. A finish schedule tracks materials and installation timing, not geometry. So the 3D CAD interference check is the best approach for identifying clashes.
