Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

The students should, at the end of the unit, be able to conceptually design a bridge through the selection, in a wide library of structural solutions, of the most appropriate ones to be implemented. To achieve it, he will rely on his knowledge of these technical solutions, but also on his acquired ability to integrate various other conceptual aspects as the feasibility and the economy of the project.
