“Since the practice was founded by Klaus Bollinger and Manfred Grohmann in 1983, we have been driven by our passion for good architecture and innovative construction. As responsible engineers, our focus is on strengthening and developing the respective individual draft. We regard ourselves as being partners in an interdisciplinary planning team and develop custom solutions together with architects and developers, construction firms and the construction industry as well as the relevant specialist planners. These are always an integral component of the overall concept and never created as an end in themselves.”

Engineering achievements are often not noticeable to those viewing buildings, but without them, there would be no houses or  buildings. And it reflects well on engineers if their work allows the architecture itself to shine. It is in this sense that the Bollinger + Grohmann Ingenieure practice has come to regard itself.

Its solutions in the fields of structure planning, facade planning, construction physics and fire prevention always strengthen and  build upon the respective architectural drawings provided. Staff at this practice founded in 1983 regard themselves as being partners in an interdisciplinary planning team and develop custom solutions together with architects and developers, along with the relevant trades and specialist planners.


These begin with the drafts and come to form an integral component of the overall concept. In dialogue, plans come into being which transform even the boldest architectural ideas into projects that are technically and economically realisable, without surrendering an iota of their creative ideas.

European Central Bank, Frankfurt, Germany. Architecture: Coop Himmelb(l)au, Vienna, Austria Paul Raftery

Thanks to its spiry design, the new construction of the European Central Bank in Frankfurt thrusts into the skyline of the financial  metropolis, where it seeks a connection to the high-rise buildings of the private financial institutions. But it’s a gesture of space:  because when all’s said and done, we are talking about the financial institution for all European citizens. Architects from the Austrian Coop Himmelb(l)au agency have expressed this self-conception in the form of two towers, which extend in full height above a glazed atrium.

The two striking towers, 185 and 165 metres tall, are connected to each other via walkways, ramps, steel struts and reinforced concrete floors, thus giving the impression of being one single entity. Another exceptional constructional challenge that faced the engineers was the integration of the listed market hall in the grounds of the new building. The 220 metre long, 52 metre wide brick building was carefully restored. As part of this, the restoration concept was created in close cooperation with the authorities responsible for listed buildings. Today, the large market hall provides the main entrance to the high-rise structure on its northern side, and apart from the lobby, primarily hosts conference rooms and the ECB’s press centre.
