Tunnels play a transformative role in enhancing connectivity and mobility, but their success hinges on robust financial sustainability, which is deeply intertwined with geological risk and sensitivity analysis. This webinar aims to explore two critical aspects: (i) achieving a comprehensive understanding of the geological model, and (ii) assessing the impact of geological uncertainties on risk and sensitivity analysis.

Geological uncertainty is a pivotal factor influencing the economic viability of underground infrastructure projects. Preliminary investigations, often constrained by high upfront costs, are essential but may lack the depth needed to fully address epistemic uncertainties related to tunnel alignments or facility locations. This limitation can significantly affect project outcomes and financial sustainability.

Robust project preparation—grounded in expert-led fundamental investigations—emerges as the most effective risk mitigation approach. The webinar will also highlight the role of blended finance as a mechanism for risk-sharing, emphasizing collaboration among stakeholders to balance geological risks and financial commitments. By integrating geological expertise into financial planning, professionals can enhance decision-making and ensure the long-term success of tunnel projects.
