Traditionally, risks have been managed indirectly through the engineering decisions taken during the project development. In this paper we consider the present risk management processes that can be significantly improved by using systematic risk management techniques throughout the tunnel project development. By the use of these techniques potential problems can be clearly identified such that appropriate risk mitigation measures can be implemented in a timely manner.
