At the worksite for the second section of the VL9 main wastewater drain (between shaft P1 at Maisons-Alfort and shaft P3 in Créteil, by Paris), the TBM Anne, designed and built by Soletanche Freyssinet subsidiary CSM Bessac (VINCI Construction), was lowered to the bottom of the shaft in the night of 31 August/1st September (photo), and baptised on 8 September.

Entrusted to a consortium headed by Dodin Campenon Bernard (VINCI Construction), with the participation of Soletanche Bachy (Soletanche Freyssinet) and CSM Bessac, the project calls for the creation of a 3,185 m-long tunnel (internal diameter: 3 m) at a depth of 23 m.

It involves the construction of two deep shafts (one of them featuring Hydrofraise-formed diaphragm walls), as well as the civil engineering and shaft equipment works.
Contract value: €46m.
