The panel will take audiences through the full landscape of modern tunneling design.

Pillar 1 – Rock and tunneling reality: The inherent geological uncertainty and variability in underground works, how rock‑mass characterization feeds into modeling assumptions, and where simplified approaches reach their limits.

Pillar 2 – Numerical modeling as the backbone: The practical role of 2D and 3D analyses in tunnel design, covering calibration and interpretation, support optimization, staged excavation, and convergence–confinement methods.

Pillar 3 – Eurocode and design governance: The gap between Eurocode expectations and tunneling realities, highlighting numerical modeling as a verification and decision‑support tool that must maintain clear traceability, safety factors, and documentation.

Pillar 4 – BIM and connected data: How BIM and digital twins apply specifically to tunnels—linking geometry, ground models, and analysis results—and how digital processes can better manage subsurface uncertainty and ensure transparent assumptions when moving from geological or design models into numerical analysis.

Pillar 5 – User experience and adoption: Reducing modeling friction and improving transparency of assumptions and results, why intuitive user experience is as essential as theoretical accuracy, what pain points typically slow down tunnel modeling, and the role of AI tools in the tunnel design process.
