What defines us
Holistic structural engineering from Harsefeld for construction projects worldwide
Since 1973, we have been designing structures that meet the highest standards of safety, economy, and longevity. What began as a family business in Harsefeld, Lower Saxony, is today a globally operating engineering firm – known for precise calculations, clear communication, and constructions that deliver on their promise.
Over 35,000 completed projects across multiple continents have made us specialists – particularly in wind energy and building construction. Complemented by solid expertise in civil engineering and our provision of health and safety coordination (SiGeKo), we support construction projects from initial calculations to safe construction sites – whether in Germany, Europe, or overseas.
