Gallery: Marine piling work completed for Grand Paris Express site

Société du Grand Paris has said that work to create a pier on the river Seine to transport tunnelling waste from construction work on the Pont de Sèvres station, as well as the station itself, is nearing completion.

The project promoter has release images showing completion of the marine piling work for the cofferdam facility which will be used by Horizon Group, formed by ETPO and Bouygues.

Société du Grand Paris has said that the scheme on the river bank between Pont de Sèvres and la Seine Musicale will help avoid placing 200 lorries on Parisian streets each day once construction of the Pont de Sèvres station gets started.

Managing the logistics of road transport for work at Pont de Sèvres station was considered too complicated with motorway interchange, residential and office buildings, underground networks and a bus station, as well as the river itself, in close proximity to the construction site.

“The land-based part of the Pont de Sèvres site is very limited, but we have managed to turn this urban environment constrained to our advantage with the creation of a pier in the Seine, whose role is central,” said explains civil engineering and works manager Aymeric Gellée.

The 150m long, 7m wide structure will be used as a pier but the watertight structure will also to allow the station box to extend a few metres into the Seine.
