The first part of the civil engineering concept design for Rome's new Metro Line C has been completed by a joint venture between Gibb, Team Engineering and Austrian tunnelling specialist Geoconsult. The jv's 12km section of the project will include 20km of running tunnels and 13 stations. It runs from a site next to the Coliseum and will pass under several historic structures, through volcanic and alluvial soils and areas of catacombs. Tunnelling will take place using a combination of full face tunnel boring, the new Austrian tunnelling method and cut and cover. Gibb project director Martin Stevenson said: 'We are taking on board all the lessons that can be learned from the Heathrow Express collapse.'
