Réhabilitation du pont de Vaucresson

TENDER DESCRIPTION

The Vaucresson Bridge, built from 1937, allows the reinstatement of the RD182 above the A13 motorway (interchange no. 5). The deck has a specific design (particularly cantilever supports) and significant degradation (deterioration of concrete, advanced corrosion of steel reinforcements, etc.) that it is now impossible to treat effectively. It is therefore necessary to plan its rehabilitation as soon as possible to avoid any accident and an emergency closure for an extended period. The chosen operation consists of carrying out design studies and works through a design-build contract with prior competitive dialogue considering the complexity of the works to be carried out and the still existing uncertainties (technical choices, cost, timeline, optimization of the no-traffic period, motorway closures, etc.) The Vaucresson Bridge, built from 1937, allows the reinstatement of the RD182 above the A13 motorway (interchange no. 5).
