The Vinci construction and Spie Batignolles built near the institute Gustave-Roussy an amblemic station of the grand paris express.
To allow the passage of the tunneller of station 14 wich is a priority over station 15, a temporary apron on cylinder was made at a depth of 36m00. Mills carried out the studies and implementation of the touréchaf shoring and the installation of 2400 m² of formwork. The Escalib Mills have been installed to allow the traffic. A Mills Acram footbridge was installed over the tunneller’s passage. Today, Mills makes the perimeter slabs of the 8 floor levels in orange quarter, which requires the rotation of the shoring materials by the 35 companions.
