ISMG TC222 Overview

• **ISMG (International Society for Soil Mechanics and Geotechnical Engineering) Overview: **
  • 90 member societies
  • ~20,000 individual members
  • 37 technical committees: 7 fundamentals, 21 applications, 9 societal impact

TC222: BIM and Digital Twins

• Focus: BIM and digital twins for geotechnics
• Council Members:
  • Chair: Magnus
  • Vice Chair: Mik
  • Secretary: McStor
  • Co-members: Yich and Andu
• Communication: Website, LinkedIn, YouTube
• Content Recording: Available on the YouTube channel post-workshop

Digital Standards for Geotechnics

• Objective: Write guidelines and recommendations, facilitate collaboration and standard development
• Organizations: BuildingSMART, OGC, AGS, DIGGS
• Key Players: AGS, DIGGS, BuildingSMART International (BIM)
• **Issues in Standardization: **
  • Semantics: Different terms for same concepts
  • Sophistication: Balancing human and machine-readable formats
  • Technology dependence: Various formats (CSV, XML, JSON)

Geotech Interoperability Experiments

• GEOTECH-IE: Focus on interoperability between standards
• Goals: Unified semantics, common conceptual model, implementation guide
• Outputs: White paper and detailed technical documentation
• **Classifications and Extensions: **
  • Concepts mapping between various standards
  • Standard extensions to OGC and ISO
  • OGC API for Geotech investigation data

Presentation: AGS Data Transfer Format

• Presenter: Neil Shadwick
• What is AGS: Data transfer format for ground investigation data
  • Scope: Factual geotechnical and geoenvironmental data, not interpreted or design data
• History: Established in 1992, widely adopted in the UK and other countries
• AGS Data Format:
  • Data Structure: Groups (tables) and fields (columns)
  • File Format: CSV-like format, easy to understand and relatively compact
• Usage: Cross-organizational data transfer, common in UK projects
• Future Directions: Next versions, API explorations, potential AGS 5
• Relationships with Other Standards: Participation in OGC interoperability experiments, alignment with IFC

Presentation: DIGGS Data Standards

• Presenter: Dan Ponte
• What is DIGGS: US-based XML schema for geotechnical and geoenvironmental data
• Structure: Extended using GML and OGC standards
• Development: Initiated by US DOT and ASCE, managed by Geo-Institute of ASCE
• Implementation: Emerging vendor support, recognized by AASHTO
• Data Model: Based on object classes and associative structures
• Current and Future Directions: Extensions for geophysical data, monitoring, and construction activities
• Interoperability: Engagement in OGC interoperability experiments

Presentation: IFC for Geotechnics

• Presenter: Jonas
• Why IFC: Integration of ground models into BIM environments
• IFC Tunnel Project: Including geotechnical data in the IFC schema
• Goals: Support factual data, geotechnical and geological interpreted models, ensure semantic and spatial integration with infrastructure projects
• Focus on: Interpreted models, uncertainty representation, linking with external files and property sets
• Implementation Status: Conceptual model completed, in progress

Wrap-Up and Conclusion

• Workshops Recap: Digital standards are crucial for future geotechnics and BIM
• Role of ISMG TC222: Continue fostering collaboration between standards bodies
• Next Workshop: Planned for May 2023
