Safety in tunnels - during construction and in operation - is a subject that has been brought to attention again and again in recent years - influenced by incidents, media and authorities. Through the example of the major Koralm Tunnel project, it is explained how the requirements, but also the understanding and the implementation of safety on the construction site have changed and developed over the years of project development. Various project phases are described like EIA, design handed in for approval, tendering and construction. The client was, for example, required to produce a detailed safety concept as part of the preparation of tenders and prepare for its implementation during the construction phase. Client and design team thus intrude into areas, which were formerly left to or transferred to the contractor. In the implementation, it turned out that the delineation of responsibility between contractor and client becomes ever more complex and blurred due to this "preliminary work" by the client. The challenge for the future is to increasingly create awareness of the responsibility of the individual in the implementation of the concept and clarification of open questions. This is described through details from the contract Koralm Tunnel 2 (KAT2). © 2012 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.
