Bridging the gap between BIM and GIS
3 likes724 views
This document discusses bridging the gap between geographic information systems (GIS) and building information modeling (BIM) to build a sustainable railway network using consistent digital information. It proposes collecting data once at the source and sharing it throughout the asset lifecycle. Current GIS and BIM standards like InfraGML, IFC, and LandXML are examined for integrating railway design data with 3D reality models from lidar scans. The document demonstrates a proof of concept for extracting rail information from point clouds, reading 3D LandXML designs, and comparing plans to reality. It concludes that BIM-GIS integration is relevant for infrastructure and that software like FME can help fill interoperability gaps.

- 3. Build a sustainable, safe and reliable railway network based on the same digital information.
- 5. BUILDING INFORMATION MODEL Existing Conditions Data Engineering Data As Built Data Maintenance Data … … Monitoring Data PIM(CAPEX)AIM(OPEX) Information Graphical Non- Graphical Documents
- 7. BIM for Infrastructure Complete Up-to- date LinkedOpen Accurate Collect data only once at the source, multiple use throughout the lifecycle BUILDING INFORMATION MANAGEMENT
- 9. FLUENT ● To anyone who needs it ● Desired structure/format ● Flexible WE WANT OUR DATA INTEGRATED ● Linked across disciplines ● Troughout entire lifecycle ● Less duplicates/loss
- 10. GIS • Small scale • Geospatial CRS • Surfacic (2D) • Topological network • Surveying as source • Standards: GML (OGC) BIM • High schale • Engineering CRS • Volumetric (3D) • Element composition • Standards: RailML, IFC, LandXML (BuildingSMART)
- 11. FROM GIS TO BIMODEL
- 12. GIS $$$ EAM
- 14. IFC ● BuildingSMART ● Support for vertical infrastructure ● Latest: IFC4 + 2 extensions ● STEP or xml format ● Use with FME already well established and documented ● No alignments
- 15. IFC Alignment ● Terrain features ● Train, road, bridge, etc. ● IFC Alignment standard published 2015 ● IFC5 supported in future versions of FME?
- 16. ENRICH LandXML WITH GIS
- 17. LiDAR Constant monitoring of railway network. LandXML Design data of new rail infrastructure. Compare Analyze 3D data Map & Notify Provide asset management with relevant information BIM & GIS INTEGRATION A realistic proof of concept

- 19. READ 3D LandXML 2D FME 3D FME • Read 2D PVI points • ArcPropertySetter for arcs • Create profile curve • Combine profile and plan to create 3D line
- 20. Compare Plan - Reality LiDAR LandXML
