The elementary and community school in Stuttgart-Plieningen was expanded with a separate extension. This became necessary due to the growth of the community school and the conversion of the elementary school to all-day operation.
The new building was constructed using an innovative timber module design and founded on a solid reinforced concrete floor slab with frost protection. The timber modules were prefabricated in the factory and assembled on site. Thanks to the innovative construction method, the construction time could be significantly reduced.
The structure of the modules can be described as follows, using a classroom as an example: a classroom was divided into three transportable individual modules. The modules were given a thin floor plate made of cross-laminated timber, beams in the middle of the room and side or partition walls to the neighboring room. The ceilings were designed as horizontal panels and firmly connected to the walls, which transfer the loads to the floor plate. The individual modules were temporarily supported and braced during construction.
In smaller areas where no modules were planned, individual timber ceiling elements were prefabricated and lifted into place. The interior was completed on site. The entire system is braced by continuous reinforced concrete and cross-laminated timber walls.
Since the new building was constructed while the school was in operation, disruptions to school operations and noise pollution from the construction site had to be kept to a minimum.
