Mechanized tunneling has long relied on the collection of vast amounts of operational and geotechnical data, but until recently, this information remained fragmented—distributed across TBM logs, monitoring reports, and design models. The emergence of Digital Twins  marks a shift from simple data acquisition to data intelligence , creating a real-time virtual counterpart of the tunnel that evolves in synchrony with the excavation process. In this context, the digital twin inte

In geotechnical engineering, data quality governs design reliability. The ground model is not a report — it is the analytical foundation upon which every parameter, simulation, and decision depends. Yet, while computational modeling has evolved rapidly, data management often remains anchored in fragmented, manual processes. Despite the widespread use of numerical tools, engineers still spend extensive time processing borehole logs, laboratory results, and monitoring data deli

This case study presents the application of DAARWIN , a cloud-based geotechnical platform, to perform real-time calibration of a PLAXIS numerical model  during the excavation of a deep retained cutting  for a high-speed rail project. The goal was to enhance confidence in design parameters, optimise temporary works, and implement the Observational Method  at full operational scale. Project Overview The case focuses on a deep retained excavation  forming part of a high-speed r

Efficiency in geotechnical engineering is no longer defined by the speed of simulations but by the quality and consistency of the data behind them. While engineers have long debated which constitutive model, Mohr-Coulomb, Hardening Soil or others, best captures ground behavior, the real differentiator is not the model itself but the reliability of the parameters that feed it. In this context, DAARWIN, an intelligent engineering software for geotechnical analysis, transforms t
