Project objective<\/strong><\/p>\n

The works constitute Lot 6 of the widening of the A6 Turin\u2013Savona Motorway carriageway in the section between Fossano and Priero.
\nIn addition to the executive construction design, throughout all construction phases our Company provided the contractor with technical assistance and geotechnical consultancy.<\/p>\n

Main works<\/strong><\/p>\n

Branzola Viaduct<\/em>
\nComprising 18 spans with variable span lengths from a minimum of 17.0 m to a maximum of 35.4 m, for a total length of 516.2 m.
\nThe viaduct deck is a prestressed reinforced-concrete structure built with precast girders erected by mobile crane.
\nThe piers and abutments are reinforced concrete with hollow rectangular cross-section and heights ranging from 7.00 m to 46.90 m; located on a steep slope with high susceptibility to instability, they are founded on caisson foundations.<\/p>\n

Ellero Viaduct<\/em>
\nComprising 8 spans with span lengths ranging from 65 m to 90 m, for a total length of approximately 601 m.
\nThe viaduct deck, launched by incremental launching, consists of two CORTEN steel I-girders 4.4 m deep, connected by lower and upper bracing and vertical diaphragms to form a torsionally stiff box, with an in-situ reinforced-concrete slab.
\nThe piers and abutments are reinforced concrete with hollow rectangular cross-section and heights ranging from 7.00 m to 46.90 m; located on a steep slope with high susceptibility to instability, they are founded on caisson foundations.<\/p>\n

Bozzolo Viaduct<\/em>
\nBuilt with a composite steel\u2013concrete deck structure with a three-span continuous-beam static scheme, for a total length of approximately 211 m.
\nThe deck consists of two CORTEN steel I-girders, 4.40 m deep and spaced at 5.00 m, connected by lower and upper bracing and vertical diaphragms, with an in-situ reinforced-concrete slab.
\nThe piers, with hollow rectangular cross-section, are 28.50 m and 26.80 m high, with caisson foundations.<\/p>\n","protected":false},"featured_media":1595,"parent":0,"template":"","settore":[26],"class_list":["post-3559","realizzazioni","type-realizzazioni","status-publish","has-post-thumbnail","hentry","settore-road-infrastructures"],"acf":[],"yoast_head":"\nWidening and safety upgrading of the A6 Turin\u2013Savona Motorway between Fossano and Priero (Lot 6). - IGEAS Engineering S.r.l.<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.igeas.com\/en\/projects\/widening-and-safety-upgrading-of-the-a6-turin-savona-motorway-between-fossano-and-priero-lot-6\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Widening and safety upgrading of the A6 Turin\u2013Savona Motorway between Fossano and Priero (Lot 6). - IGEAS Engineering S.r.l.\" \/>\n<meta property=\"og:description\" content=\"Project objective The works constitute Lot 6 of the widening of the A6 Turin\u2013Savona Motorway carriageway in the section between Fossano and Priero.
