The subcontract amounts to EUR10.7 million. The bored diameter is 5.98 m, which is a cross-section of 28.09 square metres, while the inner diameter equals 5.20 m after lining with precast concrete segments. Geology consists of slates and quartzitic slates, metamorphic rock composed of limestone and silicate, schists and quartzite, granodiorite and granitic porphyries. SELI will use a TBM DSU 0598.119 that it supplied together with the associated back-up equipment and train. The rock will be taken out of the tunnel by an H+E conveyor belt. The official launch of the TBM took place on 19th September. Visit www.selitunnel.com and www.helogistik.deFCC and Copisa will construct several other associated works: a connecting tunnel to the TBM-driven tunnel, a ventilation shaft and a cavern for the TBM disassembly. Access to the tunnel has been built using traditional means. The other parts of the project will use a Liebherr mobile crane, a FIAT-Kobelco excavator and a Sandvik jumbo.
