School building made of regional wood



On the Plateau de Diesse above the Lake of Biel, a new wooden schoolhouse will soon be built. Chappuis Architectes SA won the architectural competition and is now planning the new building. Timbatec is currently preparing the tender documents and ensuring that the school building will be built with wood from the communal forests.

In February 2020, the client and the planning team were greatly relieved: the building loan of around CHF 14 million Swiss Francs was approved. The schoolchildren of the municipalities of Plateau de Diesse and Nods can look forward to their new learning facility.    

Of course: A wooden building made of regional wood 

Because wood stores CO2 during its growth and has an excellent climate balance, the naturally renewable raw material was used as a building material from the very beginning. Almost half of the area of the Plateau de Diesse community south of the Chasseral is covered with forest. The trees of these forests will be used to make collums and beams for the school building.   

No problem: Even with public tenders 

The Federal Law on Public Procurement defines the method of a tender procedure. Projects such as the Plateau de Diesse school building must be put out to public tender. According to the principle of non-discrimination, no claim may be made with regard to the origin of materials. It is therefore not permissible to demand Swiss timber. The provision of the wood by the builder himself (in-house procurement) can be an ideal solution in these cases. Timbatec supports the client and the architects in this procurement process by preparing the tender documents and the specifications for the procurement of the wood resources.  

Early planning is necessary

In autumn of this year the trees suitable for the school building will be felled. To enable the foresters to get the right trees from the forest, the cross-sections of the components must be defined. A rough work plan must therefore be available at this time. During the winter months the trees are cut and dried so that glulam can be produced in March 2021. Erection work will then begin in summer 2021 and we look forward to another exciting project using regional timber.
