The fix
How to fix MEP/structural clash in your authoring tool
Concrete, tool-specific steps. The check itself is schema-agnostic and works for IFC2x3, IFC4, IFC4x1 and IFC4x3.
| Authoring tool | How to fix |
|---|---|
| Revit | Run Interference Check between the MEP and structural categories, then reroute services or add coordinated openings/sleeves. |
| ArchiCAD | Use Collision Detection between MEP and structural elements, then reroute or add openings. |
| Tekla | Run a clash check against the linked MEP reference model and add penetrations/openings where needed. |
| Allplan | Use collision check between MEP and structure and reroute or add openings. |
How it works
Find and fix it in the browser
The whole flow runs client-side — your IFC file never leaves your machine.
01
Open your IFC file
Open IFC Viewer Online and drag & drop your IFC file. It is parsed locally in your browser via WebAssembly — nothing is uploaded.
02
Run the Health Score validation
Run validation. The "MEP/structural clash" check (RULE_CLASH_MEP_STRUCTURAL) flags every affected element and pinpoints it in the model tree.
03
Re-validate
Re-export from your authoring tool and re-run validation to confirm the issue is resolved and your Health Score improved.
