The art of tunnelling is partly the art ofmanaging risks. ISO 31000:2009 defines risk as an effect of uncertainties on objectives. To be able to handle risks in tunnelling a more unambiguous definition should be applied. In the article the definition of the risk as a multiplication of probability of occurrence and the consequence of failure is used. The process of risk management according to ISO 31000 is presented. This process is however aimed at covering a wide range of contexts in society. Tunnelling is a branch of branch of economy exposed to risks, which characteristics are different compared to other civil engineering projects. That is why it needs specific standards. International TunnellingAssociation and International Tunnelling Insurance Group developed a set of standards, which are focused on dealing with risks in underground construction projects. A strong emphasis is put on managing geotechnical risks and on communication and cooperation between all parties.As example the risk analysis on St. Gotthard Base tunnel is presented.
