Quais de Vilaine, place de la République and around the Palais du Commerce

Rennes Métropole has entrusted the consortium Phytolab-Ingerop-Unité-Vicarini with full design and construction supervision for demolishing the Vilaine parking lot and redeveloping 750 metres of the quays. This major project aims to restore the riverine character of the historic center and to rethink the city-river interface. Key tasks in this project include demolishing the parking structure, built in the 1960s, which currently covers the Vilaine River.

They also aim to reinforce the République slab and the “Hennebique” concrete vaults dating from the early 20th century. The installation of floating docks on the Vilaine, the creation of a footbridge and terraces overlooking the river, as well as the urban and landscape redevelopment of the quays and place de la République, are also central to these tasks. Ingerop is deploying its teams specialised in urban development, civil engineering structures, particularly rehabilitation and river engineering.

Actierra handles regulatory aspects, while Geos is responsible for geotechnical work.
