tunnels are complex systems tunnels are become a more & more complex and involve following disciplines geology, geotechnic, soil and rock mechanics civil work and structure more and more complex operating equipment ventilation air pollution - environment safety operation and training San Juan Seminar - 29th & 30th of March 2006 2
tunnels are complex systems tunnels are also expansive construction costs : one time operating costs : all the tunnel live (higher than construction) value engineering and optimisation process from the beginning of the design a cross analysis of all topics mentioned above to: optimise the alignment and length profile • geology – ventilation – tunnel traffic capacity … optimise the functional cross section • excavation cost … guarantee a high safety level San Juan Seminar - 29th & 30th of March 2006 3
