Practical Geo Scan guidance on Reality Capture Design Coordination Clash Detection for architects, developers and project teams.
Clash detection involves checking where two building elements occupy the same space—e.g., a new HVAC duct hitting an existing structural beam. Reality capture ensures the 'existing' part of this equation is accurate to millimetres.
Risk mitigation. It gives the design team confidence that their proposed layouts will actually fit. This is critical in complex plant rooms or tight ceiling voids where tolerance is minimal.
