It is indisputable that tunnelling is one of the fields with the highest potential of risks and dangers in the entire building and construction industry.
Thus exits a wide range of experiences, studies, guidelines and acts referring to the safety topic. However, this applies to a large extend only to the operating phase of tunnels. There is still a lack of generally accepted and detailed rules, standards and measurements for safety at the construction phase of tunnelling projects.
Thereby, a sophisticated safety management which spans all project phases can help to reduce time consumption and cost as well as it can lead to a higher level of safety on construction sites. Consequently a deliberate safety conception can significantly contribute to the added value of a tunnelling project.
