Bring BIM into the Semantic Web
BIM
Example: „Intelligent‟ Virtual Environments
See video on: http://www.graphisoft.com/ftp/marketing/vbe/int/01/01.html
„Intelligent‟ Virtual Environments
1. The quest for extra information
2. What virtual environment to use?
3. Bringing the information into a virtual environment

1. The quest for extra information
2. What virtual environment to use?
3. Bringing the information into a virtual environment
What Virtual Environment to use?
- Investigation of existing virtual environments
- Decision to build a new virtual environment relying on
existing game engine technology
- Investigation of existing game engine technology typically
used for visualisations in construction industry
An alternative Virtual Environment
1. Esperient Creator
2. 3DVIA Virtools
3. Unity3D
4. Quest3D
5. StoneTrip ShiVa
The best choice?
“None fits, each is possible”:
1. Relatively small differences in functionality
2. Limited level of information exchange with AEC / BIM tools
3. Importance of „side parameters‟: cost, development
support, usage statistics, etc.
=> Unity3D was our choice, BUT a more in-depth study AND
usage is to be considered

Evaluation
Main objectives achieved:
- Bring BIM information into the Linked Data cloud
- Easy visualisation of building models in a virtual environment
- Access BIM information and other information in the LOD cloud from
within a virtual environment
Further research needed:
- Further explore possible connections between building models and
information in the LOD cloud
- Improve the user interface for a more intuitive usage
