what we think

The passion for high-quality architecture and innovative structures has been the motivation for Klaus Bollinger, Manfred Grohmann and their team since the foundation of the office in 1983. As responsible engineers, our prime focus is the strengthening and enhancement of each individual design.

We see ourselves as partners within an interdisciplinary planning team. We develop tailored solutions together with architects and clients, construction companies and industry. These are an integral component of the complete concept and not an end in itself.

Besides technological innovation Bollinger + Grohmann Ingenieure prides itself in open-minded dialog and fair respectful dealings with all stakeholders. We are convinced that sustainable solutions can only develop in unison with technological and social progress.
