Direct Answer
The Tekla model is exported as an IFC file, which Revit can import as a reference link. Alternatively, Trimble's Tekla-to-Revit plugin (or direct IFC link) allows real-time coordination. The structural model appears in Revit as a reference, and the architect can check clearances, elevations, and penetrations without owning a Tekla license.
Full Explanation
IFC (Industry Foundation Classes) is the open BIM exchange format. Tekla exports IFC 2×3 or IFC 4, both of which Revit can link. The IFC file contains geometry, classification, and properties for every structural member. In Revit, it appears as a linked file that can be toggled on/off in views. For real-time coordination, Trimble Connect provides a cloud-based viewer where both Tekla and Revit models coexist and clash detection runs automatically.
What This Means for Your Shop
When the architect modifies the building envelope after steel detailing has begun, the IFC exchange process allows the structural team to quickly assess whether any steel is affected. This is far faster than redlining PDF drawings back and forth.
Common Mistakes
Exporting a preliminary Tekla model to Revit and treating it as the final coordination reference. Models must be clearly versioned so the coordination team knows which Tekla model revision is in their reference file.
Recommended Process
Establish a model exchange schedule at project kickoff: Tekla exports IFC at design milestones (60%, 90%, IFC). Label each export with date and revision. The GC's BIM coordinator loads each into the federated model and runs clash detection. Results are distributed as an RFI list.
