Stadlau and Hirschstetten tunnels

The renovation of Stadlau and Hirschstetten tunnels and the ramps nearby Vienna started in 2014 and TBT carries out the fire protection of ceilings and parts of walls as well as the noise protection for our client, ARBEITSGEMEINSCHAFT TUNNEL A23  (STRABAG and PORR AG). Each of the tunnels is nearly 500m long, the ramps add up to 900m and there are several hundreds of meters of wood-cement sound absorption outside of the tunnels.

The West part including the ramps were finished in the first phase, in spring and summer of 2016, and the installation works now continues.
