The construction works for the New Cadiz Bridge started in April 2007 and the completion is scheduled for autumn 2011. By now, important challenges have been faced, such as the construction of 495 deep piles both inland and on sea, which has demanded innovative excavation solutions. The semi-submerged pier and tower bases have required composite steel-concrete watertight caissons of 1200 tons maximum weight, built inland and placed on site with heavy lift floating sheer-legs, to face the action of the 7 m-high water column, waves and ocean currents. Finally, the rising of the east tower is being developed with a climbing system in the first vertical phase, combined with a complex three-dimensional steel structure anchored to the tower to support the scaffolding of the highly inclined diamond-shaped second phase (only 41º above the horizontal line). |
