[WEBINAR REPLAY] Exchange of ground model and interpreted data – Introducing AGSi

This webinar took place on 25th Nov 2020 11:00
Duration: 1hr 30mins



This webinar replay from the Association of Geotechnical and Geoenvironmental Specialists sees the official launch of AGSi; a new transfer format for ground information, in particular ground models and interpreted data.

Developed by the AGS Data Management Working Group, this new format has been created for anyone involved in the construction or sharing of ground models, whether they be geological, geotechnical, hydrogeological or geo-environmental, or as a solution for anyone who has found themselves looking for:

• An industry standard non-proprietary method for transferring a ground model and/or interpreted geotechnical parameters to another organisation.
• A way of importing your ground model into a BIM model that does not involve lots of reprocessing or data loss.
• A common data format for ground information that your analysis software can understand, making automation of design workflows much easier.
AGSi will complement the existing AGS Data Format, (which is used for the transfer of factual data from ground investigation and monitoring). No prior knowledge of the AGS format is required for AGSi.

This webinar covers the following:

• Background to AGSi
• Use cases and potential benefits
• Overview of the schema, diving into detail in some areas
• Introduction to JSON encoding
• Practical examples
• Tips on how you could use AGSi today
• Where to find the (online) documentation
• Relationship to the existing AGS format
• How AGSi fits in with other model formats (e.g. IFC Geotechnical)
• Future plans




At Jacobs, we’re challenging today to reinvent tomorrow by solving the world’s most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.



Jérôme Chamfray (BEng)
Chief Geo-Digital Engineer, Jacobs

Jérôme is member of the AGS Data Management Working Group. He has contributed to the development of industry approaches to BIM and Digital Engineering on Ground Engineering and Tunnelling projects. His expertise is centred on ground modelling, design automation, data management and BIM using AGS geotechnical data combined with 3D spatial information. Jerome also has significant experience in the development of design automation approaches for geotechnical assets which provide significant time and cost savings.

His wide range of expertise and valuable knowledge have led him to be identified as a technical expert on large multidisciplinary projects in South Africa, Middle East and the UK.

Neil Chadwick
Independent Consultant & Digital Geotechnical Specialist

Neil is a geotechnical engineer with special expertise in geotechnical data management and the application of BIM and digital workflows in geotechnics. He is a member of the AGS Data Management Working Group and is the lead author of AGSi. He is also part of a worldwide initiative on geotechnical data standardisation jointly organised by buildingSMART and the Open Geospatial Consortium.

Until recently, Neil was an Associate at Arup where he spent over 20 years working on major projects in the building and infrastructure sectors, including Crossrail, Westfield Stratford City and the London 2012 Athletes Village.


David Farmer
Geotechnical Engineer, Arup

Dave is a geotechnical engineer at Arup and a member of the AGS data management working group. He specialises in geotechnical data management and ground modelling with a keen interest in digital design and automation.  Dave has a broad knowledge of BIM, CAD and GIS applications for geotechnical and geo-environmental use.

Osvaldas Tylenis
Senior Software Engineer, Bentley Systems

Osvaldas Tylenis is a Senior Software Engineer at Bentley Systems and a member of the AGSi subcommittee.  He has designed and developed geotechnical data management solutions since 2008 with a specialisation on 3D modelling and AGS data. Over the last two years he has worked on OpenGround Cloud and proof of concept systems for the AGSi format inside of Bentley and other systems.
