Department I – Structural Engineering
Department I reunites all structural engineering sections and the Structural Design Control Authority.
From earth work and foundation engineering to mass wall, metal, timber, masonry and glass construction, from reinforcement and fixings to facades and load-bearing plastics, from structural design approvals to topics such as safety theory, fire and seismic design – structural design is our focus in Department I. Come rain, hail or snow, structures in Germany are safe, not least thanks to the approval and assessment work of DIBt.
