Geotechnics Day 2019

The Future of Geo-Engineering, 5 November 2019

Retrospective

The Geotechnical Engineering Day was held on 5 November 2019 under the theme "The Future of Geo-Engineering". It was a day that focused on the rapid changes within the geo-engineering profession, in which new technologies such as cloud computing, sensors, and AR/VR are playing an increasingly prominent role.

Technological advances were the central theme. For example, it discussed how more powerful software and cloud computing are paving the way for dynamic models that can calculate real-time design adjustments. This makes it possible to analyse alternatives faster and more efficiently, significantly changing the way design and decision-making processes work.

Innovations such as 3D printing of free-form concrete and circular design were also discussed. These developments require a new approach to geotechnical design, with reuse of materials and sustainability becoming more prominent.

The growing availability of data through low-cost sensors, drones, satellite measurements and public data sources was another important theme. Geotechnicians need to find ways to use all this information efficiently. In this regard, AR and VR technologies are playing an increasing role, especially in combination with Building Information Modelling (BIM), which will dramatically change the working methods of both consultants and implementers in the coming years.

Is the geotechnical consultant of the future more of a 'software developer' than a traditional engineer? With the emergence of project-specific software and building-block models, the role of the consultant might change dramatically. Nevertheless, subject-specific knowledge of ground behaviour remains crucial. Advanced software can do a lot, but it is the engineer who needs to understand where the limitations lie.

A key conclusion of the day was that, despite digital developments, the importance of engineering judgement remains unchanged. The key message was clear: "Garbage in = garbage out." The quality of input remains essential for reliable results, regardless of the power of technology.

The Geotechnical Engineering Day 2019 offered an inspiring and forward-looking look at developments in the field, focusing on both the opportunities and challenges of digitisation for geotechnical engineers.
