The Joint Venture MeCtNord, composed of Webuild and Impresa Pizzarotti & Spa, have contracted to CRCHI, TBM Technology and Anbel the supply of a TBM EPB - 9.36 m diameter- to be used to excavate the 12.5km tunnel for the Giampilieri- Fiumefreddo railway, lot 2 Taormina-Giampilieri, on the Messina-Catania line, Sicily. These tunnels will cross weak rock formations with highly variable characteristics and behaviors along the route, that will require a frequently change to the operating mode, from close mode to open mode.
Therefore, the TBM will have such characteristics as to be able to efficiently excavate long sections in the rocks, with cutter thrusts and cutter-head revolution speeds higher than the usual range of a standard EPB TBM.
