How to Create GIS and BIM Interoperability
12 likes19,679 views
The document outlines strategies for achieving interoperability between Building Information Modeling (BIM) and Geographic Information Systems (GIS) using FME software. It highlights the benefits of using BIM for detailed infrastructure information and GIS for geographic analysis, while addressing challenges like data complexity and file sizes. A case study involves the restoration of Mount Vernon's historical site, showcasing practical applications of combining BIM data with GIS for improved stakeholder access and data utilization.

- 5. Why use BIM? ➔ 3D digital representations of infrastructure ➔ Includes descriptive info (dimensions, materials, manufacturers, etc.) ➔ Aids in proper design, construction, operation, and maintenance ➔ Drawback: files size and complexity make data difficult to repurpose
- 6. Why use GIS? ➔ Map and analyze geographic features ➔ Uses location and imagery ➔ Conveys data on a large scale ➔ Data models, attributes, simple geometries, and domains

- 8. How can FME Help? BIM data is very complex. BIM Software Exports - Overly complex (IFC) - Overly simplified (DWG) With FME - Keep info you need - Discard info you don’t
- 9. BIM to GIS at Mount Vernon VIRGINIA, USA Patrick Gahagan, Esri Quinn Evans Architects Mount Vernon Ladies’ Association CASE STUDY
- 10. Mount Vernon • George Washington’s home, constructed between 1758 and 1778 • Mount Vernon Ladies’ Association tasked with restoration, interpretation, and preservation of grounds and structures • Mansion laser scanned to create architectural-quality HBIM in Revit by Quinn Evans Architects
- 11. BIM to GIS via FME (Data Interop) • Revit: Add coordinates and rotation from project north to true north • Export to Revit Archive(.rvz) with FME Revit Exporter, attributes to spreadsheet • Import to ArcGIS with Data Interoperability Extension (FME) • Reconnect attribution
- 12. A Blended World
- 14. Stakeholder Access to Information • Browser delivery provides data to everyone, even fire suppressant system designer • Historical data identifies plaster from 1950 vs. 1787 • Framing details assist with optimal routing
- 15. A navigable, queriable world provides minute detail and the big picture to all stakeholders – BIM/GIS pros or not.
- 16. How it’s done...
- 17. FME Revit Reader Plugin Data Views
- 18. Problem: Exporting from Revit to Sketchup and PDF
- 19. Solution:
- 20. Key Takeaways: Revit Data Views in FME produce 3D data ready for use.
- 21. Problem: Extract floorplans from BIM into GIS for routing
- 22. Solution:
- 23. Key Takeaways: No transformers, data views do the work.
- 24. Problem: Where in the world? Extracting or using the georeferencing methods in Revit Official flag of Null Island nullisland.com
- 25. Solution:
- 26. Override the coordinate system when using survey point. Key Takeaways:

- 28. IFC
- 29. FME IFC Reader/Writer ● Data Model ○ Hierarchical ○ Relative ● Representations ○ Body ○ Annotations ● Property Sets ○ Geometries ○ Features
- 31. Solution:
- 32. Key Takeaways: Hierarchies are complex but can be tamed.
- 33. Problem: Reduce BIM Data Volumes
- 34. Solution:
- 35. Key Takeaways: Removing detail is necessary for efficient viewing. Understanding geometry hierarchy is useful when working with BIM. GQuery (Geometry XQuery) can increase the utility of many transformers.
- 36. Problem: Create Slim-BIM from CAD/GIS
- 37. Solution.
- 38. Key Takeaways: ● A starting point BIM model can be quickly created from GIS ● IFCProperty Set Definitions are created in the workspace using transformers ● IFC Property Sets are stored as part of the geometries in IFC and are populated from GIS attributes
- 39. Problem: Update BIM from Excel Tables
- 40. Solution:
- 41. Key Takeaways: IFC data can be extracted to Excel and edited. FME can merge changes back into IFC. Change your BIM data without using your BIM tools!
