Transformation from Classical 2D to Digital 3D Thinking Process in the Design of Geotechnical Structures: Perspective of a Geotechnical ConsultantÂ-Video

Video Transcription

Video Summary

The speaker describes adopting a 3D digital workflow for geotechnical design, using the foundation design of three large LNG tanks as an example. With many boreholes, complex geology, and tight deadlines, engineers struggled to form a reliable mental picture from numerous 2D sections. They built 3D subsoil models and extracted representative sections to support design decisions, communication, and planning of pile installation.<br /><br />The models also helped interpret pile-load tests and compare predicted rock depths with conditions recorded during construction. Discrepancies revealed limitations in the original site investigation and the effects of human error, underscoring that models are only as reliable as their input data and should not imply certainty beyond the evidence.<br /><br />Python automation streamlined design, software interfaces, and reporting, reducing repetitive work and errors while improving responsiveness. Although a fully digital process remains challenging, the speaker urges engineers to start small: 3D visualization makes subsurface conditions easier to understand, and automation lets engineers focus on higher-value work.
