Did you know?
Safe Software and Consortech have been partners for over 10 years.
We are SAFE SOFTWARE - data lovers and the makers of
FME. What’s FME?
A powerful integration engine that can be deployed by Desktop, Server, or Cloud. Check out www.safe.com for a 2 minute demo.
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
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
Why extract from BIM?➔ Visualization
planning, site suitability
➔ 2D floor plansrouting, maintenance
➔ Analysisspace management: scheduling / leasing, energy / HVAC
➔ Construction managementas built vs design
➔ Facilities management maintain and replace components, work plans, reporting
➔ Updates keep BIM current, add reference links
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
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

Agenda
§ What is BIM?
§ Client Context
§ First Steps towards BIM § CAD to GIS for BIM with FME § Sharepoint to Vault with FME
§ Role of FME in BIM § BIM for Infrastructure § BIM for Buildings
BIM LifeCycle
Three Categories
Revit Civil 3D
Navisworks InfraWorks 360
Vault AutoCAD Map
Design Tools Integrators Information Management
An Airport is like a City
• Manage real-estate
• Large CAD inventory, all 2D
• Sharepoint document management system • Difficulties managing CAD specifics such as reference drawings
An Airport is like a City
• Difficult to share plans across business lines • Maintenance • Operations • Security • Etc.

Objectives for BIM
ü Use BIM in both their construction projects and in internal management ü Long-term: Integrate with asset and facilities management solution (SAP)
Challenges
• The main challenge is moving data into different systems

Role of FME in CAD to GIS
Analysis Conversion Validation
FME was used at multiple steps
Analysis
• FME inventoried each drawing • Layer names • Object Types (lines, text, blocks…) • Object Counts
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 validation a) Layers to do manually
Conversion Challenges
• Attribute mining based on proximity
• Matching text values to a domain value
• Keeping the Data Freeze short
Angle Calculation
• Match
Angle Calculation
Domain Challenge
Quality Control
• Validated counts of features that arrived in database against number expected.
• Validated attribute matches, and texts that were unmatched
Benefits of using FME
• Restructuring (parsing layers names, text matching)
• Validation and Reporting
• Simulation

VAULT MIGRATION
Vault Implementation
Migration from Sharepoint to Autodesk Vault
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
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
Solution
• Used FME to extract the data from Sharepoint and load the metadata into Vault
Files
Metadata FFS
Extraction from Sharepoint
1. to FFS Read content ID
Read XML Field
Build data extraction
Generate report
Fields process validation
Write file content
9
Write metadata to FFS
Domains process validation
Load into Vault
Read metadata FFS File
Read attribute definition from Vault
Generate specific insertion query
Generate importation report
Read related info from Vault
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)
Benefits of FME
• TurnKey solution
• Avoided manual loading, minimizing risk
• The translation could be simulated
WHAT’S NEXT WITH BIM?
BIM Continuation
• There are several ways that FME can help going forward
• Interoperability between different BIM tools
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
Moving to BIM for Buildings
• Compare Revit files
Moving to BIM for Buildings
• Create lighter Building models for Integration into InfraWorks
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.
GIS <-> BIM: Transformation
Attributes● Schema mapping● Resolving relationships
Geometry● Geo-referencing● Conversion / Extrusion
(2D to 3D)● Instances● Appearances● Validation
BIM Formats
Reading:● Autodesk Revit, FBX● IFC● CityGML, IndoorGML (BIM-lite)
Writing:● IFC● CityGML (ADE’s), IndoorGML
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
Problem: Create Slim-Bim from CAD & GIS
Solution
IFC Result: Create Slim-Bim from CAD & GIS
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
Problem: Reduce BIM Data Volumes
Solution
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

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

SummaryBIM 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
