Banverket, the authority responsible for rail traffic in Sweden, and builder Skanska-Vinci are now discussing who will bear the economic responsibility for the extra costs.
The giant drill used to drill the tunnel has to be replaced due to wear and tear caused by extreme amounts of water pressure as well as the hard rock on site. It is also now known that the drill was not optimally designed to begin with.
The tunnel being built through Hallandssåsen, in southwestern Sweden, has been under way since the 1990’s. During the earlier stages of the project another contractor was responsible for the construction, which ended in a total fiasco causing major water damage in the area and greatly delaying the project.
Those problems were also related to drilling, but a spokesperson for the project says there is absolutely no relation to the problems occurring now and those of the past.
