Runway tunnel, Vienna Airport

Austria

Implementation of a new tunnel safety concept made it necessary for a tunnel to be structurally reinforced. This was done by adding a 45cm thick fibre-concrete inliner, with integrated corbels, between the existing bored piles of the tunnel,
for fire-safety reasons.
