Risk Management in Tunnelling Projects

Tunnelling is a risky business but the project teams undertaking such work have had a great range of successful tunnels completed to the satisfaction of tunnel users, whether rail passengers, car drivers or utility users. But there is always improvement to be had and dangers to watch for. This meeting will try and assist in an understanding of this and other subjects under the broad title of risk and delivered with the assistance of representatives from the insurance industry.
