Parallel Open Session and Session 2




Open Session: Tunnel failures – causes, risks, mitigation

Inherent to tunnelling, or in need of more diligence?

A review of common design and construction procedures and their attainment of reliability and safety. Are there still gaps be closed in common design procedures, the application of existing standards and guidelines? What has the industry learned from past failures? Which developments do we need to better manage uncertainties and risks in tunnelling?

Representatives from the international tunnelling communities from different backgrounds (clients, designers, contractors, insurers will share their views and thoughts in short presentations. The subsequent moderated discussion among the panelists and with the audience will revolve around the variety of technical, organizational and economical aspects and roles throughout project lifecycles.
