To support the licensing procedure for an interim storage facility for hazardous waste, we relied on experts who had already proven their competence in the respective fields in many previous projects. The safety report prepared by the experts of the weyer gruppe was an essential part of this licensing procedure. We particularly appreciated the high level of expertise, the adherence to deadlines and the solution-oriented approach. I would also like to emphasise the positive discussion atmosphere at all times, which contributed significantly to the good cooperation.
