On the 20th of March 2018 pupils of the 8th grade were able to get information about different occupational areas. The Institute for Structural Concrete (IMB), the Institute for Structural Analysis (LBB) and the Institute for Steel Construction (Stb) had chosen the topic "Structural Engineering - Designing the World". Various exhibits such as crude ore, steel profiles, steel tension and steel compression specimen, coloured concrete and glass textiles were shown. Particularly interesting was the "translucent concrete". The glass fibers used let light shine through the concrete. As a highlight, a bending beam made of reinforced concrete was tested every hour.
