This project entails the extension of the Catania Circumetnea metro, which is partly operating and partly under construction, in Catania’s urban area. This infrastructure has unique technological characteristics and represents one of the most interesting European urban interventions, being used by more than 3,400,000 passengers a year.
The tunnel, hosting two railway tracks, was designed providing a mix between conventional and mechanised excavation techniques.
Lot Nesima-Misterbianco and lot Stesicoro-Airport include:
▪ 5 stations
▪ 3,5km of tunnel
▪ 13 ventilation openings
The design included the Building Risk Assessment (BRA) and the geotechnical monitoring, inside and outside the tunnel.
