The research undertaken by LGCGM (Civil and Mechanical Engineering Laboratory) focuses on the problems linked to the construction of bridges and the behavior of soils, materials or structures in areas linked to mechanical construction. LGCGM is a student training team (Equipe d'Accueil, EA) made up of research teams from INSA Rennes and the University of Rennes 1 (Institutes of Technology in Rennes and Saint-Malo).
