The contract has been awarded to a JV between Provera e Carrassi and Polidori Costruzioni on 19th March, 2007. The executive design approved by ANAS, the national road administration, has been undertaken by Alpina. The project mainly consists in completing the San Lazzaro junction, constructing the San Giacomo tunnel and the Sanremo Centre junction. The scheme stretches 2,150 metres approximately in all. Construction of the San Giacomo tunnel and work supervision amount to EUR22 million. Visit www.proveraecarrassi.it and www.alpina-spa.itThe San Giacomo single bore tunnel is 1,501.68 m long. The excavated area varies from 100 square metres for the typical cross-section to 160 square metres for the enlarged cross-section where lay-bys will be bored to allow vehicles to park in case of emergency. There will be four such lay-bys, each approx. 60 metre long. There are no other underground structures within the project.The tunnel path crosses the Ligurian Alps and the geology is formed by a series of tectonic units, transported and piled up towards the outer limits of the Alpine furrow, which form part of a deformation of the Apennine age. The San Giacomo tunnel fully crosses Sanremo flysch, which consists of clayey schists, clayey marls and fine to medium sandstone. Narrow alluvial deposits run along the San Francesco and San Romolo rivers, predominantly fine materials, sand alluvium with gravels.Full-face traditional methods will be used, combining drilling and blasting and hydraulic breakers, depending either on the ground or the cover above the tunnel to avoid damage caused by vibrations to overlying buildings. A unique excavation face will be opened in San Lazzaro, working towards Sanremo Centre.The variety of Sanremo flysch obliges to adopt different support measures, ranging from Swellex bolts, shotcrete and welded mesh to steel beams and shotcrete. In particularly tricky geological areas, the face will be stabilised by fibre-glass nails or by drilling forepoles of steel piles inserted into holes and filled with cement to form an umbrella vault around the contour of the face. Visit www.swellex.comDumpers and rubber-tyred loaders will be used to take the excavated material from the face to a first dump site outside, where it will be crushed prior to be taken to the final dump. The tunnel follows the path of an existing pilot tunnel built by highway operator Autostrada dei Fiori during the final design phase to study the rock mass and optimize the subsequent cross-section designs and tunnelling methods.
