The construction of the first tube of the Tauern tunnels in the years 1970 to 1975 was a milestone in the development of the NATM and of modern tunnelling. Completely new methods were introduced and used successfully to overcome the strongly squeezing rock, which was the only possibility of mastering the large rock deformations and completing tunnelling within the planned deadline. The driving of the second tube of the Tauern tunnel between 2006 and 2008 has shown that the basics of the NATM are still valid. The considerably more favourable system behaviour does, however, show that the state of knowledge in design and construction has developed greatly. The major difference is the increase of productivity and this is made clear by comparing the production assets used.
