Grossaffoltern school facility is erected
29.09.2022
In Grossaffoltern, the school complex is being expanded with a new building containing classrooms for the entry level. To ensure that the construction phase progresses as quickly as possible, the timber construction elements are prefabricated. For this, planning accurate to the millimeter is the be-all and end-all.

The entire construction work of the Grossaffoltern school space organization (new building as well as conversion of the existing school building) will take around two years and should be completed by the end of 2024. In a first step, a new one-story wooden building will be built along Schulhausstrasse, completely detached from the existing building, with the classrooms for the entry level.

The factory planning - for a smooth construction
A great advantage of timber construction is the fast construction speed thanks to high prefabrication. For a smooth production of the cross laminated timber panels and the timber construction elements, a complete planning is the be-all and end-all.
For the new building in Grossaffoltern, we prepared the workshop planning with production and element plans, control and correction plans as well as assembly plans in the SIA phase 51 execution project. According to these plans, the cross laminated timber panels were processed and the timber elements were manufactured. This enables the fast and frictionless erection of the timber structure. There is no more rolling planning even during the construction of the building, as is often the case with solid buildings. This saves costs and time.
The building - a design by Bienert Kintat Architekten
Inside the school building, the cross laminated timber panels remain mostly visible. This requires particularly precise and careful work in production and on the construction site. It gives the school building a particularly pleasant indoor climate, which has a positive effect on everyday school life. The offset floor plan and the round windows in the roof and exterior walls give the building its unique character. You can find out more about the design on the website of Bienert Kintat Architekten.
TS3 - for large areas made of wood
The TS3 technology is the result of over ten years of research and development by Timbatec Holzbauingenieure Schweiz AG together with the ETH Zurich and the Bern University of Applied Sciences in Biel. Today, the technology has been outsourced to an independent company and is successful on the market. The new process joins wood components together by joint grouting and without pressing pressure on the face side. Together with the specially developed column head elements, TS3 enables large areas to be made of wood - without the joists that were previously common. These large surfaces are suitable for floor slabs in large buildings such as schools, hospitals or administrative buildings and can replace reinforced concrete in most areas. At the school building in Grossaffoltern, a total of 127m3 is planned in the attic as a canopy with TS3.
