GeoBIM – a tool for optimal use of geotechnical data
1 like905 views
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.

- 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 2015-06-11 www.tyrens.se 8

- 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 2015-06-11 www.tyrens.se 23
