SCOPESCOPE We strive to be a bridge between the world of
enterprises (manufacturing/construction) and the world of research
We want to give a completely satisfying answer to the demand for a better integration between these two worldsworlds
We deliver all scientific and technical help to promote innovation in civil constructions new and existinginnovation in civil constructions, new and existing buildings, including historic and artistic ones
