As-Built BIM & Cesium Documentation for Digital Twin Platforms.
Digital twin development teams need precise, current as-built data — not design intent. We deliver LOD 300–400 Revit models, clean IFC exports and Cesium-ready 3D Tile packages so your platform reflects physical reality from day one.
Common Challenges in This Sector
What firms in this sector typically struggle with when it comes to drafting and documentation.
As-Built Accuracy
Design BIM models don't reflect what was actually built. Scan-to-BIM and field-verified as-built modeling is needed for digital twins to function correctly.
BIM Data Quality
Poor BIM quality — missing parameters, broken geometry, generic families — creates problems downstream in digital twin platforms and IoT integrations.
Format Conversion Pipeline
Digital twin platforms typically require IFC, 3D Tiles, or custom formats — conversion from Revit often requires specialist processing steps.
Ongoing Update Cycles
Physical assets change. Digital twins need regular as-built model updates as facilities are renovated, expanded or reconfigured.
How Draftitecture Helps
Specific ways our team supports firms in this sector.
Scan-to-BIM for Accurate As-Builts
Laser scan point clouds processed into precise as-built Revit models — LOD 300–400 with real dimensions, not design intent.
IFC Export & Validation
Clean IFC 2x3 and IFC4 exports from Revit, validated against common BIM checker rules and ready for digital twin platform ingestion.
Cesium 3D Tiles from BIM
Revit and IFC models converted to georeferenced Cesium 3D Tiles (tileset.json) for spatial digital twin visualization layers.
BIM Model Maintenance
Ongoing as-built model update service — we process revision documentation, field changes and new construction phases to keep the BIM current.

- IFC 2x3 and IFC4 exports
- tileset.json (Cesium 3D Tiles)
