Mainfeldschule is a temporary school development for around 800 pupils. The facility is located on a split plot of land in Niederrad district, Frankfurt. The two sections of the site are each home to a three-storey school building made of prefabricated CLT (Cross Laminated Timber) elements. The structure on the eastern section of the plot consists of a conventional load-bearing construction. This is partly underpinned by a waterproof reinforced concrete basement. In contrast, the western structure sits on a solid ground bearing floor slab.

Long-Span Bridge Construction as Connection

A large-span timber bridge structure connects both buildings at second storey. In addition to carry out structural planning work for the school facilities, Werner Sobek provided building acoustics consulting and helped to create an external waterproofing concept.  Werner Sobek also developed the waterproof materials plan for the development’s basement structure and foundation components.

The prefabricated timber-construction-modules can be executed both as area modules and 3D room modules. Both cross-laminated timber and timber-concrete composite constructions can be loaded via the foundation components.
