Design and sizing of deck elements, preparation and follow-up of calculation notes and construction documents, taking into account the construction sequence, temporary situations and construction constraints.
Illustrative photoFounder ExperienceDetailed design of standard bridges on several projects: PRAD-type precast prestressed beam bridges on the Strasbourg Western Bypass (COS), filler-beam structures in La Réunion and slab bridges on the A75. Work included structural design, preparation of calculation notes and follow-up of construction documents, according to the scope of each project.
