Gymnasium, Bösingen FR
2014
On behalf of the municipality of Bösingen, Timbatec AG carried out an expertise on the roof of the gymnasium. It showed that the structural safety of the supporting structure was no longer guaranteed.
The project
The initial situation After the expert report had been submitted, the hall had to be closed immediately because the structural safety of the supporting structure was no longer guaranteed. The gusset plate trusses were too weakly dimensioned for the latest generation of standards and had to be replaced.
The construction
Strengthening the old supporting structure was out of the question for cost reasons. The municipality therefore decided not to renovate the old roof but to replace it.
The challenge
Since the gymnasium is directly adjacent to the community center, the external appearance could not be changed. The new supporting structure was built with trusses that span the width of the hall at intervals of 4.5 meters.
