Risk is ever present in the underground works sector; however through proactive risk management and involvement of a risk advisor at an early stage, associated risks can be understood, allowing for informed decisions about the financial aspects of project risk and requirements for  insurance. The result is lower premiums, hence lower total cost of risk and cost savings, reducing the final out turn costs and improving the project program.  This paper discusses the concept of insurance premiums being based on a sound understanding of project risks by insurers and highlights the crucial role of the insurance broker. Furthermore, it describes the Code of Practice for Risk Management of Tunnel Works, how a proactive approach can benefit tunnel projects, the Code’s  link to best Risk Management practice and how it can be applied to any civil engineering project, bringing the same benefits.
