is a doctoral researcher at the Professorship of Technical Education at TUM School of Social Sciences and Technology. The focus of his work in C07 is on the competence and qualification requirements of the involved experts in order to have trained professionals for a later implementation of AMC. For this, the different processes must be analyzed in their entirety from the perspective of handling and problem-solving activities.

Doctoral researcher at IGP: The researcher Will Provide an inspection process chain utilizing new digital tools to perform the quality inspection of the as-built model of AMC products (mainly concrete) with its digital twin on the component level. Moreover, the next focus would be building scale monitoring of the construction site and establishing accurate coordinate systems to support the positioning during the project.
