FCC reports its involvement in the construction of the 11.6 km Caravia to Llovio stretch of the Autovia del Cantabrico dual carriageway with three tunnels of total length 2.35 km. Overall value of the ongoing contract is $130 million. More detail from www.fcc.es April 2000. Ute Sella, a jv of Dragados and FCC, is working on three twin-tube tunnels on an 11.6 km-long section of the Autovia del Cantabrico near Ribadesella. El Fabar 54 sq m top heading is being developed to the halfway point at 700 m from the east portals using two Atlas Copco L2C drillrigs and three Wagner ST8B Scooptrams. The whole operation will then be moved to the west portals in order to keep the LHD tramming distances realistic. A 3 m bench will be excavated through the tunnel after completion of the top heading. Geology is limestone with slate, and quartzite with karst cavities filled with clay. Round depth limited to 1.5 m, with steel arches, mesh, Swellex rockbolts and steel fibre reinforced shotcrete for support. Some 4 m/day advance is being achieved in each face. Tezangos tunnel is 470 m long and is advancing from the east in slates and sandstones using similar techniques and equipment, and the Llovio tunnel is yet to start.
