More in detail, it is the result of an ambitious project aimed at the substitution of the historical overground railway line.<\/p>\n\n\n\n<p>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. Under the technical point of view, the system is characterised by three functional components: tunnel, stations and compensation shafts.<\/p>\n\n\n\n<p>The tunnel, hosting two railway tracks, was designed providing a mix between conventional and mechanised excavation techniques.<\/p>\n\n\n\n<p>The 11 stations were conceived referring, case by case, to both cavern and cut &amp; cover layout. The best solution was adopted according to the specific set of boundary conditions.<\/p>\n\n\n\n<p>Compensation shafts, finally, were sized to comply with both fire brigade and ventilation requirements. The geotechnical and structural analysis of these civil works were complicated by the presence of a really challenging geological formation, characterised by the interaction between the shallow lava stone layer and the underlying sedimentary clay bed.<\/p>\n\n\n\n<p>In this exciting context, SYSTRA SWS was required to provide engineering services for tunnels, stations and compensation shafts, developing also highly specialist value engineering analysis.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" width=\"1080\" height=\"773\" src=\"https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1.jpg\" alt=\"\" class=\"wp-image-2099\" style=\"width:696px;height:auto\" srcset=\"https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1.jpg 1080w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-300x215.jpg 300w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-1024x733.jpg 1024w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-768x550.jpg 768w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-474x339.jpg 474w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-800x573.jpg 800w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-180x129.jpg 180w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-153x110.jpg 153w, https:\/\/www.systra.com\/italy\/wp-content\/uploads\/sites\/5\/2024\/06\/catania-1-230x165.jpg 230w\" sizes=\"(max-width: 1080px) 100vw, 1080px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"author":103,"featured_media":2099,"parent":0,"template":"","type-market":[50,46],"project-market":[],"project-service":[],"project-location":[],"type-service":[],"type-solution":[],"class_list":["post-2098","projects","type-projects","status-publish","has-post-thumbnail","hentry","type-market-tunneling-underground","type-market-urban-mobility"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.4 (Yoast SEO v27.4) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>CATANIA METRO LINE EXTENSION, Nesima \u2013 Misterbianco - Italy<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"CATANIA METRO LINE EXTENSION, Nesima \u2013 Misterbianco\" \/>\n<meta property=\"og:description\" content=\"Mixed conventional and mechanised tunnel excavations applied Catania metropolitan line is currently characterised by a total length of 8.8km, with 11 operating stations from Nesima to Stesicoro.
