In Thun, Switzerland, the first apartment building with a basement made of wood is currently under construction. The construction industry has a responsibility and must significantly reduce its CO₂ emissions to comply with the Paris Climate Change Convention. This can only be achieved by dispensing with more steel and concrete in building construction. Source: Timberbiz
There is a lot of CO₂ in a basement. Basements and underground car parks have been constructed in concrete within wooden buildings until now.
Now in Thun Timbatec’s cross laminated timber boards lie on a 160mm thick insulation board and black insulation encases the wood for moisture protection. TS3 joints connect the individual CLT panels with each other.
Timber Structures 3.0 technology, or TS3for short, is a process that is used to generate large areas from wood. Cross laminated timber manufacturers pre-treat the front sides of the panels in the production plant with a primer and sealing tapes. On site the panels are poured with a two-component polyurethane casting resin without pressure. The same construction was chosen for floor panels.
In the apartment building it is not only the wooden basement that is an innovation. The building is also the Living Lab of a research project in the field of digital planning and BIM (Building Information Modelling).
The “DeepWood” research project, together with the Lucerne University of Applied Sciences and Arts and the Bern University of Applied Sciences, is developing the basis for real-time and team-oriented cooperation.
The building was planned with the 3DX platform from Dassault Systèmes using CATIA. Initial findings show the strengths of the integrated project space: there are no interface problems to be solved. In order for the new approach to timber construction to establish itself, well-designed processes, routines and templates are needed – from planning and collaboration to automatic plan output and machine control.
