Life Cycle Cost Aspects (LCC-Aspects) have become an important subject for tunnel owners and operators, private or governemental. In the last few years, tunnels have been increasingly equipped with the latest (safety) technology, to the extent that these costs easily account for 25% of the total tunnel investment. But the life time of these systems is approximately five times lower than the tunnel infrastructure.
