IABSE Congress, Stockholm 2016: Challenges in Design and Construction of an Innovative and Sustainable Built Environment, 2016

The building presents a great architectural and structural singularity, and was designed and completed in just one and a half years.LCC has a rectangular shape in plan, with dimensions of 100 x 60 meters, and a total height of around 45 metres above ground. The building required several column-free large spaces, to meet the demands of its use (large meeting rooms and exhibition areas, with the main one located at an upper level and occupying almost the entire floorplate) and its architectural intention, including a large opening that houses an open-air terrace hall. The structure has therefore to accommodate spans of more than 40 metres. In addition, being located in a highly seismic area, the building is subject to significant horizontal forces.The main seismic resistant structure is formed by a very rigid ...

BIM permite llegar al inicio de obra con un diseno inequivoco, perfectamente definido y coordinado, de modo que se pueda ofertar ajustadamente y planificar el desarrollo de la obra por parte del contratista. Para ello es necesaria la colaboracion e implicacion temprana de los diferentes agentes que intervienen en un proyecto, desde los disenadores hasta el constructor, pasando por la propiedad. IDOM ha implantado esta metodologia en su proceso de elaboracion de proyectos, de forma casi total en los proyectos de edificacion y hasta cierto punto en los de infraestructuras. En el articulo se describen ciertos aspectos que la metodologia BIM implica en los proyectos de estructuras y de infraestructuras, asi como una serie de ejemplos de proyectos en los que se ha empleado.

It connects two residential neighborhoods and provides access to the park for both pedestrians and cyclists. The innovative main structure of both the bodies is a conical spatial steel truss of circular section, with curved diagonals and straight longitudinal chords, all of them inscribed in two tronco-conical surfaces. The diagonals run along four helixes, which may be grouped into two families of contrary directions. The geometrical arrangement thus generated responds to the architect's aesthetic purpose. This configuration determines the structure of the footbridge bodies that—although have an adequate overall depth in relation to the span and, being a truss, a favorable structural type for a longitudinal structure, lose part of this favorable disposition due to the curving of the diagonals, which introduce undesirable bending stresses in the diagonals. In addition to the unusual shape and dimensions, the foundation is very complex and is greatly conditioned by the existence of underground motorway tunnels and sewers.
