Lot 854 “Underground works and cut and cover tunnel at Vezia” is for the construction of the entrance in Vezia to the Ceneri Base Tunnel including approximately the first 550m of the south to north tunnel. This is sub-divided primarily into three categories of work: underground works, cut and cover tunnel, external works and final landscaping of the area. The underground works include the construction, using traditional methods (explosives), of dual single track tunnels (2 x 340m c.) and a connecting passage. The cut and cover tunnel is a 220m long box section structure in reinforced concrete with a connecting passage. Final completion work will consist of filling in over the top of the tunnel and laying out the car parks. The project also includes a culvert for a torrent, the construction of some retaining walls and also the construction of a new municipal road link.
