Two experienced installation experts have travelled from Matrei to Switzerland a few days in advance to prepare everything at the building site. This preparation work is essential, as the lorries arrive on site on an almost hourly basis across a four-day period. Before each bathroom is lifted from the lorry by crane, brought to the correct floor and moved close to its final position using a rolling frame – a process that should take just ten minutes in all – numerous details have to be coordinated with building management.
A year under lock and key
Once the bathrooms are in place, the two installation experts will remain on the building site for a week, bringing each bathroom into position with millimetre precision, levelling them off and connecting them floor by floor. In one year, the pair will again travel to Alpnach Dorf shortly before final cleaning of the finished building. Only then will they open up the bathrooms, which have been locked with fire doors up to this point, and attach the final doors.
