Department I – Structural Engineering

Department I reunites all structural engineering sections and the Structural Design Control Authority.

From concrete and masonry to load-bearing metal, glass and timber constructions, facades and load-bearing plastics, from structural design approvals to issues such as safety theory, fire and seismic design to stability of wind energy plants. 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.
