SIF is constructing the enclosure of the excavation site and the foundations for the new headquarters of the Lombard Odier bank in Geneva. Lombard Odier is a bank, as well as a wealth and asset manager.<\/strong><\/p>\n<\/div> The \u201cOne Roof\u201d building will bring together the six existing sites in Geneva under one roof. It will house all the Lombard Odier<\/a> group\u2019s activities, including up to 2,600 workstations, on a new site a stone\u2019s throw from the lake, the motorway, a train station and the International Organisations district.<\/p>\n The \u201centerprise totale<\/em>\u201d (Swiss term for main contractor) is led by the C3 consortium composed of Construction Perret, Patrice BEZOS (architect) and C2I (developer).<\/p>\n SIF, as part of a consortium with Grisoni-Zaugg, Perrin Fr\u00e8res and ISR Injectobohr, is responsible for:<\/p>\n The geology of the site is complex, with alternating backfill, natural gravels, moraines and a molasse stratum of varying altitude. The piles\u2019 length needs to be adapted according to the level of the molasse roof encountered.<\/p>\n The transmission of significant loads (up to 1100 tonnes\/pile) requires a diameter of 1500mm for half of the 150 foundation piles. The creation of 1500mm diameter piles is a first for SIF!<\/p>\n<\/div>\n
