In the heart of Hamburg's Überseequartier, a corrugated glass roof is being constructed according to a design by Werner Sobek Ingenieure. The Roschmann Group developed the nodes for the extensive structure, which is characterised by its unusual geometry and filigree design.
The new urban quarter offers a mix of commercial, retail, catering, office and residential space. Its roads, walkways and squares are covered by 213 tonnes of glass with 8535 individually shaped triangular, quadrangular and pentagonal glass panes. They create a light but sheltered space and lend the building an impressive lightness. The transparent roof blurs the boundaries between inside and outside and ensures a high-quality and unique spatial experience.
The filigree mesh of metal and glass integrates 4592 different steel nodes. They were milled from 315 tonnes of raw material and form the heart of the structure. The chips produced during the milling process were fed back into the material cycle as ingredients for new alloys. One of the nodes (equivalent to around 0.2 ‰ of total production) was a faulty part, the thread of which could not be incorporated in the project, but could be used for the exhibit at glass technology live.
Between the nodes, 8994 steel rods with a total length of 7500 metres form a construction that stabilises the structure. 6000 precisely welded connections join the individual elements together to form a complex whole. Milled aluminium nodes complement the steel structure and, together with aluminium profiles, serve as glass supports. All the individual parts were brought together in a parametric optimisation and development process to create a symbiosis of material use, stability and transparency.
