This project included the repair and reinforcement of the superstructure and substructure of the Quisi and Ferrandet viaducts in Benissa, and the replacement of the superstructure and reinforcement of the substructure of the Aguas Viaduct in El Campello.
The intervention for the Quisi and Ferrandet viaducts consisted in the repair of detected structural damage and the structural reinforcement needed to adapt the historic structures to the current loads (e.g. ground anchors have been placed at abutments to resist the breaking forces, and Shock Transmission Units have been placed at the piers to resist the seismic loads).
The intervention for the Aguas Viaduct consisted in the replacement of the deck by a new structure and the structural reinforcement of the abutments and piers to resist the current loads. The replacement of the deck was preferred over rehabilitation due to less interruption to the railway traffic.
During the construction phase, one of the two Contractors awarded proposed a deck substitution for the Ferrandet bridge. Degree of Freedom was contracted by the Contractors for the technical assessment.
