S16 Arlberg expressway, Austria
Almost 40 years after the opening of the Arlberg road tunnel in 1978, a partial renovation was carried out and at the same time escape routes were built over the supply air duct.
The Arlberg road tunnel, which has been in operation since 1978, was already connected to the parallel Arlberg railway tunnel by seven crosscuts before the STSG (Road Tunnel Safety Act) came into force between 2004 and 2007. During this phase, collecting rooms for up to 800 people were created between the two tunnels. Ultimately, the road and rail tunnels were linked with one another in terms of safety.
The client, ASFiNAG BMG, commissioned a general contractor with the construction and E+M services. The construction management department of the GC GROUP was entrusted with the tasks of the local construction supervision BAU for this complex construction project.
The task of the building supervision was to ensure an economic realization of the project in question, the observance and tracking of costs and deadlines, the minimization of risks and the assurance of the execution of services according to the state of the art. In addition, attention had to be paid to the implementation of the measures according to plan within the scope of the respective authorizations.
