BIM, Digital Twins and Risk Management for Resilience in Geotechnical Mining Projects

BIM and the evolution of geotechnical modeling

THE BIM is more than a 3D modeling tool: it is a information management system that integrates all disciplines of a project in a federated model.

In geotechnics, BIM enables:

• Multidisciplinary integration: geology, topography, hydrology, drainage hydraulics and slope stability in a single digital environment.
• Preliminary simulation of critical scenarios: rising water levels in pits, erosion in piles and slopes, pore pressures in dams, piles and slopes.
• Reduction of uncertainties: association of geotechnical tests (SPT, CPTu, triaxial tests, permeability) directly to the model.

This ability to centralize and correlate information transforms BIM into a engineering instrument, in which risks can be identified and mitigated during the project design phase.

From BIM to Digital Twin: from design to operation

While BIM represents the digital project, the Digital Twin is the living counterpart of the physical structureIt integrates, in near real time, information from monitoring systems, such as:

• Piezometers and inclinometers: measurement of pore pressures, water levels and deformations in dams and slopes.
• InSAR and LiDAR Radar: remote detection of millimeter displacements in waste piles and pits.
• Rain gauges and hydrometeorological stations: correlation between extreme rainfall events and structural response.

By consolidating this data into the digital model, a platform is created capable of:

1. Compare actual vs. projected performance, allowing deviations to be identified.
2. Anticipate instability scenarios, through simulations and numerical analyses linked to field readings.
3. Activate contingency plans based on objective indicators, reducing exposure to catastrophic failures.

Thus, Digital Twins represent an advancement in geotechnical engineering towards a logic of adaptive and resilient management, in which each monitored event feeds back and strengthens the system.

Digital Governance and Risk Management

The true value of these technologies lies in their association with internationally recognized risk management, which guarantees not only technical efficiency, but also regulatory compliance and organizational transparency:

• RIDM (Risk-Informed Decision Making): decisions driven by data from the digital model, reducing subjectivity.
• ISO 31000: integration of climate, geotechnical and operational risks into the life cycle of structures.
• GISTM (Global Industry Standard on Tailings Management): incorporation of extreme precipitation scenarios and hydrological events into planning.

With digital dashboards derived from BIM and Digital Twins, governance is strengthened with dynamic reports that can be shared with managers, regulatory bodies and communities, increasing technical security, transparency and public trust.

Resilience applied to geotechnics

The concept of resilience, widely discussed in risk engineering, means the ability to absorb, respond quickly and adapt to new scenarios proposed especially for climatic and/or unforeseen issues.

With BIM and Digital Twins, resilience is built into all phases of the project:

• Project: analysis of extreme hydrological load scenarios and multidisciplinary compatibility.
• Construction: digital monitoring of execution, minimizing deviations from the project.
• Operation: continuous monitoring that allows rapid response to anomalies, reducing the time of exposure to risks.
• Closing: Digital models preserve the historical behavior of structures, supporting rehabilitation strategies and post-closure monitoring.
