We recently started a new collaboration with a technical expert office. The AGU Zurich and the technical expert office Schröder GmbH offer joint technical and biomechanical expertise. The processing of expert opinion requests and technical accident analyses are carried out by the technical expert office Schröder GmbH. The new collaboration will complement our existing collaborations with the technical expert office Deppe & Nabe in Bavaria and the technical expert office Fuchs in Baden-Württemberg.
