Mats Svensson presents GeoBIM, a tool for optimal use of geotechnical data. GeoBIM aims to handle all types of geotechnical data in a common format with associated uncertainty values. This would allow data to be accessible, visualized, and integrated for various engineering needs. Currently, different software only handle certain data types, requiring manual work. GeoBIM would establish standards and allow powerful 3D visualization of data, as seen in examples from the Varberg railway tunnel and European Spallation Source project. Defining an uncertainty model for data could also reduce claims and costs by sharing risks. GeoBIM would help address issues of lost data over time on major infrastructure projects.

Today authorities lose data:
 Bypass Stockholm
 Varberg railway tunnel
 Hallandsås 2 x 8 km railway
tunnel

6. This is geo data

7. This is geo data

8. Why complicated?
• Many different data formats
– AGS data format (handle many but not all data types)
– in Sweden approx 10 methods (AutoCAD / GeoSuite)
• Lack of standards
• Specific software handle specific data
• No software can handle all data types
• Still a lot of manual work

15. TRUST 4.1 Developing GeoBIM
• Handling ALL geo related data and methods in Infrastructure process
• All data saved with a value of uncertainty
• Make data accessible for all needs/applications
• Visualizing data crucial

16. Varberg railway tunnel
• Geophysics visualized in
Varberg tunnel
2015-06-11 www.tyrens.se 17

17. Powerful visualization of GeoBIM
• Large projects – a lot of data
• No tools in geotechnical industry
convenient for visualization
• Use cores from computer game industry
for real time visualization in 3D

19. Model of uncertainty
Uncertainty (m)

20. A well defined uncertainty model makes
the bedrock model much more useful
Uncertainty model in tender and contract
With a well defined uncertainty model… …
the risk is defined and could be shared

21. Conclusions
• Many actors – different needs
• Data often lost
• A need for data format standard
• A need for the Geo-BIM concept
• Powerful visualization a fantastic COMMUNCATION
tool
• Uncertainty model – saves a lot of claims and money
