Hospital extension with wooden modules



The Dornach hospital in the canton of Solothurn is being extended by one floor. This happens during operation. Timbatec expresses its utmost respect for the carpenters of Stamm Bau AG and all the craftsmen working on the construction sites during this difficult time.

During several weeks, carpenters from Stamm Bau AG produced 28 wooden modules. They can be produced in the factory hall with millimetre precision. A precision that would not be possible on the construction site. In just one day, the crane lifts all the modules to lofty heights. The craftsmen assemble the wooden modules on the flat roof of the existing west wing. In this way, they create space for new offices in Dornach Hospital.  

The 44-metre long and 13.5-metre wide concrete roof must not be subjected to additional loads. A supporting structure of steel girders allowed the load to be transferred via the external walls. These girders span the entire width of the roof. As a result, they sag about 4 centimetres in the middle. Timbatec planned the modules in such a way that they lie flat after installation and compensate for the sagging. In the next few days, the module joints and the flat roof will be sealed and then the interior fittings will be completed so that the new offices can soon be handed over to the client.  

Safety and hygiene regulations observed 

Safety and hygiene regulations are strictly observed on the construction site. There is no shaking of hands and we keep our distance from each other during work. This is why work can continue despite the corona virus. Timbatec expresses the highest respect to all craftsmen and women working on the construction sites during these difficult times.
