A first on the One Roof site in Geneva, Switzerland<\/h1><\/div><\/div>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><\/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>\nThe \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>\nSIF, as part of a consortium with Grisoni-Zaugg, Perrin Fr\u00e8res and ISR Injectobohr, is responsible for:<\/p>\n
\n- 1300m of bored encased piles<\/a>, 1000mm, 1200mm and 1500mm in diameter, average length 14m,<\/li>\n
- 2700m of secant bored encased piles, 880mm in diameter, average length 14m,<\/li>\n
- 1000m of bored encased piles (880mm in diameter) for a Parisian-type wall, average length 12m,<\/li>\n
- 700m of bored encased piles (620mm in diameter) for a Berlin-type wall, average length 15m,<\/li>\n
- 450 anchors<\/a>, average length 20m,<\/li>\n
- 3000m\u00b2 of sprayed concrete.<\/li>\n<\/ul>\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>
