  A Simplified Quantitative Risk Assessment for the Insurability of Tunnel Projects

  Tunnels are unique engineering structures and their design and construction are associated with greater risks in comparison to other engineering structures. These greater risks become even further evident as tunnels are increasingly being designed and constructed to very large dimensions in excess of 15 m in size through difficult geological conditions and within sensitive, urban environments. The key risks associated with the design and construction of tunnel projects are due to the hazards of seismicity, geology, geometry, depth and design/construction methodology and the associated severity of their consequences. A prudent tunnel design must recognize and be able to address all potential risks in a flexible manner so safe and cost-effective solutions and contingencies can be developed and implemented if necessary. This paper briefly discusses type and scope of investigations required for tunnels projects to reduce risks, the key hazards associated with tunnel design and construction, and presents a simplified quantitative risk assessment that may be appropriate for insurers to consider as part of their risk policy assessment procedures.
