What is a method of checking for physical conflicts between building components within a building model?

• A. Cost estimation
• B. Schedule risk analysis
• C. Clash Detection
• D. Safety observation

Answer: (C)

Clash detection is the process of identifying physical conflicts where components occupy the same space or interfere with one another in a digital building model. In BIM workflows, teams run clash detection with software tools to automatically flag interferences between architectural, structural, and MEP systems. This lets designers and contractors resolve issues before construction starts, reducing costly rework and on-site changes. For example, it can reveal a duct runs through a structural beam or a pipe clashes with a wall cavity, so adjustments can be made in the model before fabrication or installation. Cost estimation focuses on quantities and costs, not geometry. Schedule risk analysis looks at timing and probability of delays, not physical interferences. Safety observation checks on-site safety practices, not model geometry.
