GeoBIM – a tool for optimal use of geotechnical data

  1. 1. GeoBIM – a tool for optimal use of geotechnical data Mats Svensson Tyréns AB
  2. 2. Who am I? • Civil engineer Lund University, Sweden,1990 • PhD Geotechnics/Geophysics 2001 • Consultant , Tyréns field geophysics 2002 • Head of Tyréns Geo department 2006 • Enthusiastic about – Combining different data for best geo model – Geophysics – Visualization of geo data – Well organized data 2015-06-11 www.tyrens.se 2
  3. 3. Many different actors • Hydrogeologists • Geotechinical engineers • Contaminated soil specialists • Other engineering disciplines • Society in general • Contractors • Authorities • Clients • Politicans • Media 2015-06-11 www.tyrens.se 3
  4. 4. Different needs…. Different capacity 2015-06-11 www.tyrens.se 4 Sheet pile anchor levels? Pile length? Contaminants? Hydraulic conductivity? Groundwater lowering? Stability? Vibrations? Settlements?
  5. 5. From field to long time administration 2015-06-11 www.tyrens.se 5 Today authorities lose data:  Bypass Stockholm  Varberg railway tunnel  Hallandsås 2 x 8 km railway tunnel
  6. 6. This is geo data 2015-06-11 www.tyrens.se 6 Hildedal 21/3/2003 Undersökning med EM61 (avancerad metalldetektor) V 0 5 10 15 20 25 30 35 40 45 0 5 10 15 20 25 30 35 40 45 0 5 10 15 20 25 30 35 40 45 0 5 10 15 20 25 30 35 40 45 D1 D2
  7. 7. This is geo data 2015-06-11 www.tyrens.se 7
  8. 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
  9. 9. GeoBIM concept needed 2015-06-11 www.tyrens.se 99
  10. 10. GeoBIM concept needed 2015-06-11 www.tyrens.se 1010
  11. 11. It could be like this 2015-06-11 www.tyrens.se 11
  12. 12. … or like this… ESS – European Spallation Source Lund, Sweden 2015-06-11 www.tyrens.se 12
  13. 13. TRUST – Coordination, dissemination & innovation TRUST – Information models, data structures and visualization TRUST – Holistic survey methods 1. Transparent Underground STructure (TRUST) – Management Ask, Dahlin, Kadefors, Larsson, Mahlemir (LTU – LU – Chalmers – KTH – UU) TRUST – Smart underground construction 3.1 Adaptive production methods Schunnesson & Olofsson (LTU) 3.2 Optimization of Reinforcement Johansson & Stille (KTH) 3.3 Real Time Grouting Control Draganovic, Stille, Larsson (KTH) 2.1 Geoelectric site investigations Dahlin, Auken, Rosqvist, Sparrenbom, Bastani (LU – SGU) 2.2 Multicomponent seismics and electromagnetics Malehmir, Juhlin, Pedersen, Bastani (UU – SGU) 2.3 Rock mass characterization Rosberg, Bjelm, Ask, Schunnesson, Stephens (LU – LTU – SGU) 2.4 Development of standards for functional requirements at underground facilities with respect to the chemical environment Ericsson, Mossmark, Dahlström (Chalmers – NCC) 4.1 Development of methodologies for rational and fast evaluation of geotechnical investigations Larsson, Svensson, Jonsson (KTH – Tyréns – LU) 4.2 Integrated use and interpretation of data from geophysical and non-geophysical methods for site investigation for underground construction Dahlin, Rydén, Günter (LU – LIAG)
  14. 14. 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 2015-06-11 www.tyrens.se 16
  15. 15. Varberg railway tunnel • Geophysics visualized in Varberg tunnel 2015-06-11 www.tyrens.se 17
  16. 16. 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 2015-06-11 www.tyrens.se 18
  17. 17. Example European Spallation Source (ESS) 2015-06-11 www.tyrens.se 19
  18. 18. Model of uncertainty Uncertainty (m)
  19. 19. 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
  20. 20. 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
