BIM 3D Clash detection & Clash resolution helps reduce the risk of human errors during the construction stage.
BIM Clash Detection and Resolution are one of the most important advantages of BIM Coordination. It facilitates the effective identification, inspection, and reporting of interference clash in a typical 3D project model, at the document stage instead of on-site, during construction. This helps reduce design errors and inefficiencies that may cause delays and budget issues. Minimizing the risk of human error during an inspection of models ensures sustainable design, efficient construction planning, and fabrication.
Hard Clash
When two objects pass through each other. Most BIM modeling software eliminates the likelihood for this using clash detection rules based on the embedded object data. (for example, a steel pipe in a concrete wall or a column running through a wall).
Soft or Clearance Clash
Work to detect clashes which occur when objects encroach into geometric tolerances for other objects (for example, a steel rod duct support modeled too close to a plasterboard ceiling).
Workflow or 4D Clash
Clash resolves to schedule clashes and abnormalities as well as delivery clashes (for example, work crews arriving when there is no equipment on-site).
