ABSTRACT: The uncertainties in many of the areas related to tunnels in rock mass are well apprehended by most of the entities involved in the different parts of the process. Owners, designers, contractors, insurers, all agree that geotechnical works in general and tunnels in particular have a high degree of risk that needs to be assessed and managed. In this course the justification for the importance of specific education in this area is expressed and key aspects related to geotechnical risk are presented.
