Clash Detection and Model Coordination: Best Practices
Why Clash Detection Matters
Spatial conflicts between building systems are among the most expensive problems in construction. A duct running through a structural beam or a pipe intersecting a wall cavity can cause costly rework, schedule delays, and safety hazards. Clash detection identifies these conflicts digitally before they become physical problems.
Cloud-Based Coordination
Modern coordination workflows leverage cloud platforms for model collaboration, document control, model federation, and automated clash detection. These platforms enable multiple disciplines to work on federated models simultaneously, with automated clash reports generated on a regular cadence.
Model Verification and Audit
Effective coordination requires verified models. This includes integrating survey scans in Revit to validate existing conditions, auditing models for compliance with project standards, and verifying that model elements contain the data required for downstream processes like quantity takeoff and fabrication.
Construction Visualisation and Sequencing
Beyond clash detection, coordinated models enable construction visualisation that creates dynamic, detailed representations for stakeholder communication. Construction sequencing models automate the generation of views based on the construction programme, showing exactly what gets built, when, and in what order.
Site Logistics Modelling
Site logistics modelling uses BIM to demonstrate and coordinate construction methodologies. This includes crane placement, material staging, temporary works, and access routes. By modelling logistics digitally, teams can identify conflicts and optimise construction methods before mobilising to site.
