The architecture, engineering, and construction (AEC) industry is undergoing a major digital transformation through the widespread adoption of Building Information Modelling (BIM). However, the geotechnical and underground engineering sectors have struggled to keep pace. This delay is largely due to the highly irregular and complex nature of subsurface soil and rock layers, which are difficult to map and represent in standard BIM environments. Consequently, geotechnical data and structural designs often remain disconnected in "information islands." A primary hurdle is software interoperability—the inability to transfer complex 3D geological data into numerical simulation programs without losing critical parameters or experiencing geometric failures. This forces engineers to spend countless hours manually redrawing cross-sections for analysis.
