SITES Inspection ouvrages d'art

Published on

On behalf of SOCOPRIM, SITES performed the initial in-depth inspection of a series of civil engineering structures in Côte d’Ivoire.

The Henri-Konan-Bédié bridge, a 1,500 m prestressed concrete box girder deck viaduct, and the Valéry Giscard d’Estaing interchange made up of 16 prestressed concrete slab structures were meticulously examined by SITES’ civil engineering experts.

In order to optimise downtime and reduce inconvenience for motorists, these structures in the Ivorian economic capital required the deployment of several inspection techniques, namely close inspection (on foot, by pod and by boat) combined with remote inspection. The aim of this was to monitor the lower surfaces, piers, support devices, caissons and superstructures.

Very high-resolution photography enabled digital twins to be generated for defects mapping purposes and detailed inspections.
