Activities in Code Committees and Associations

The members of the SDA-engineering GmbH are engaged in different committees and associations. The activities expand the expertise of our company and result in close contacts to approving authorities, international research institutions and representatives of code committees. 

Furthermore, we are collaborating closely with the Chair of Structural Statics and Dynamics of RWTH Aachen University, where Prof. Dr.-Ing. C. Butenweg was working as Chief Engineer for 15 years, scince he changed to the Faculty of Energy Systems at FH Aachen - University of Applied Sciences. The close coopperation with RWTH Aachen University will be continued within the Center of Wind and Earthquake Engineering (CWE) and teaching assignments.
