BIM workflows give facilities managers, architects, and engineers key information for better-informed infrastructure planning and management. But how do you migrate to a BIM system when your current data is stored in CAD? Through a real-world international airport example, find out how CAD and engineering data can be centralized in a Document Management System (Autodesk Vault) and GIS database (SQL Server Spatial) using FME, and learn how to create BIM workflows from CAD data.

6. Why use BIM?
➔ Digital representation of infrastructure:
both building information and 3D
➔ Includes descriptive info (dimensions,
materials, manufacturers, etc.)
➔ Aids in proper design, construction,
operation, maintenance & updates
➔ Drawback: files size and complexity
make data difficult to repurpose

7. 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. Why extract from BIM?
➔ Visualization
planning, site suitability
➔ 2D floor plans
routing, maintenance
➔ Analysis
space management: scheduling /
leasing, energy / HVAC
➔ Construction management
as built vs design
➔ Facilities management
maintain and replace components,
work plans, reporting
➔ Updates
keep BIM current, add reference links

9. BIM Challenges
➔ BIM is too complex for most
GIS applications
➔ Data model differences and
gaps object vs relational
➔ Limited geo-referencing
➔ File size / instanced
geometries
➔ Schema mapping
which source feature types
match GIS ones
➔ External references

10. 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

• Manage real-estate
• Large CAD inventory, all 2D
• Sharepoint document management system
• Difficulties managing CAD specifics such as reference drawings

27. An Airport is like a City
• Difficult to share plans across business lines
• Maintenance
• Operations
• Security
• Etc.

projects and in internal management
ü Long-term: Integrate with asset
and facilities management solution (SAP)

34. Role of FME in CAD to GIS
Analysis Conversion Validation
FME was used at multiple steps

35. Analysis
• FME inventoried each drawing
• Layer names
• Object Types (lines, text, blocks…)
• Object Counts

36. Conversion
Example conversion (lines)
1. Read DWG
2. Angle Checking and Text
matching by proximity 5. Write to Database
4. Prepare
Attributes
6. Reporting
b) Extra validationa) Layers to do manually

37. Conversion Challenges
• Attribute mining based on proximity
• Matching text values to a domain value
• Keeping the Data Freeze short

38. Angle Calculation
• Match

39. Angle Calculation

40. Domain Challenge

41. Quality Control
• Validated counts of features that arrived in database
against number expected.
• Validated attribute matches, and texts that were
unmatched

42. Benefits of using FME
• Restructuring (parsing layers names, text matching)
• Validation and Reporting
• Simulation

43. What’s Next?
Infrastructure
data Imagery
Terrain 3D Models

44. DOCUMENT MANAGEMENT PROJECT
VAULT MIGRATION

45. Vault Implementation
Migration from Sharepoint to Autodesk Vault

46. Pre-migration conditions
• Situation before Vault implementation
• Number of data editors: ~ 10
• Number who consult plans: 150-200
• Number who will comment plans: 50
• Number of plans that need to be migrated from Sharepoint:~
40 000

47. Analysis
• Sharepoint Database
• Files are in blobs
• Metadata in different columns
• No plan history maintained
• Vault Database
• The first database conversion simulated in our office
• Files are stored as DWG in a file directory structure
§ Client wanted to maintain same file structure

48. Solution
• Used FME to extract the data from Sharepoint and load the
metadata into Vault
Files
Metadata FFS

49. Extraction from Sharepoint
1. to FFS
Read content ID
Read XML Field
Build data extraction
Generate
report
Fields process

Write metadata
to FFS
Domains
process
validation

50. Load into Vault
Read metadata FFS File
Read attribute definition from Vault
Generate specific insertion query
Generate importation report
Read related info
from Vault

51. Challenges
• The attribute definitions in Sharepoint are embedded in XML
stored in the database
• Colonne de type sql_variant pour la valeur des attributs dans
Vault (générer le code d’insertion plutôt qu’utiliser un simple
feature writer)

52. Benefits of FME
• TurnKey solution
• Avoided manual loading,
minimizing risk
• The translation could be
simulated

53. WHAT’S NEXT WITH BIM?

54. BIM Continuation
• There are several ways that FME
can help going forward
• Interoperability between different
BIM tools

55. BIM for Infrastructure Potential
• There are several ways that FME
can help with future potential BIM
for Infrastructure Workflows
• Prepping data for InfraWorks
§ Gathering different terrain data
§ Integrating different 3D data
• Extracting Infrastructure data to do
Civil Design
• Automate Civil 3D to GIS

56. Moving to BIM for Buildings
• Compare Revit files

57. Moving to BIM for Buildings
• Create lighter Building models for Integration into
InfraWorks

59. BIM / GIS / CAD integration
workflows in FME
Tip
Download FME 2016 for
the latest support in
formats and protocols.
Plus the new FME
Workbench functionality
helps you output the
data whenever and
however you need it.

60. GIS <-> BIM:
Transformation
Attributes
● Schema mapping
● Resolving relationships
Geometry
● Geo-referencing
● Conversion / Extrusion
(2D to 3D)
● Instances
● Appearances
● Validation

61. BIM Formats
Reading:
● Autodesk Revit, FBX
● IFC
● CityGML, IndoorGML (BIM-lite)
Writing:
● IFC
● CityGML (ADE’s), IndoorGML

62. BIM: Key Techniques
A starting point BIM model can be quickly created from GIS
FME can extract IFC to Excel. Edits can be merged back into IFC.
Revit Data Views in FME produce 3D data ready for use.
Removing detail is necessary for efficient viewing.
Hierarchies are complex but can be tamed. Understanding geometry
hierarchy informs workflow design.
GQuery (Geometry XQuery) empowers transformers for BIM

63. Problem: Create Slim-Bim from CAD & GIS

64. Solution

65. IFC Result: Create Slim-Bim from CAD & GIS

66. 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

67. Problem: Reduce BIM Data Volumes

68. Solution

69. I-35 Bridge Workflow: Revit to linked CityGML
1. Bridge BIM created in Revit by DBI Architects
2. Revit Extension - FME Exporter - creates .rvz file
3. FME Workspace: Revit .rvz to CityGML conversion with embedded
component uri’s
4. VirtualCitySystems imports CityGML into their 3D City Database
5. RevMac – uses linked data tools / rdf to analyze embedded component
data

70. I-35 Bridge in Revit

71. Revit to CityGML Workspace

72. I35 Bridge CityGML: Data Inspector

73. Virtual City Map Viewer

74. GeometryValidator for 3D
• Checks for solids with
inverted faces, dangling
surfaces, unsealed solids, etc
• Flag errors with descriptions
and locations
• Chain multiple validators to
isolate problems of interest
(e.g 2d before 3d)
• Repair option

75. FME Server:
Publish BIM / 3D to the Web
Adobe 3D PDF
COLLADA / KML
ThreeJS
X3D / WebGL
Cesium / CZML
Amazon S3*

76. Customer Success Stories

77. Summary
BIM is about information management through the building life cycle from planning
through maintenance, not just design
Leveraging BIM’s value requires integration with CAD and GIS systems
This presents challenges that FME helps address with BIM - CAD - GIS workflows:
● Load from / export to any CAD, GIS or 3D format
● Transform / Validate schema, geometry and semantics
● Extract and filter from BIM – just what you need
● Automate enterprise services and updates
● Publish BIM data to client and mobile friendly formats
