City-Scale BIM, Digital Twins & Geospatial Visualization.
Supporting smart city teams, urban planners and platform developers with Cesium-based 3D city visualization, BIM-to-3D Tiles workflows and large-scale point cloud streaming — from individual buildings to full city districts.
Common Challenges in This Sector
What firms in this sector typically struggle with when it comes to drafting and documentation.
Multi-Scale Data Complexity
Smart city platforms need to combine building-scale BIM data with city-scale GIS and terrain — most teams lack the pipeline to make this seamless.
Point Cloud Volume
City-scale lidar and reality capture generates massive datasets. Processing, tiling and streaming these efficiently requires specialist workflows.
BIM-to-Geospatial Integration
Getting Revit or IFC building models properly georeferenced and integrated with city-scale Cesium scenes requires careful coordinate transformation.
Realtime Streaming Performance
3D city visualizations must stream efficiently in browsers and Unreal Engine scenes — unoptimized assets cause lag and poor user experience.
How Draftitecture Helps
Specific ways our team supports firms in this sector.
3D Tiles Generation
We convert BIM models, point clouds and photogrammetry into Cesium 3D Tiles (tileset.json) for efficient city-scale streaming in CesiumJS or Cesium for Unreal.
BIM-to-Cesium Pipelines
Georeferenced Revit and IFC exports prepared and converted for Cesium ion or self-hosted 3D tile delivery — buildings embedded in city-wide scenes.
Point Cloud Streaming
City-scale .PLY and .E57 point clouds tiled, optimized and packaged for real-time streaming via Cesium or Potree-based platforms.
Urban Documentation Support
Site plans, block models, massing documentation and existing conditions drawings to support planning and stakeholder communication.
Typical Deliverables
- tileset.json (Cesium 3D Tiles — buildings & terrain)
- Georeferenced BIM/IFC models
- Tiled point cloud packages
- City-block massing models (.FBX, .GLB)
- Urban site plans in AutoCAD DWG
- Cesium scene configuration files
