Nemetschek Engineering User Contest 2009 • Category 7: CAD Engineering, Engineering work and special structures 265 7 Skywalk - glass-steel bridge, Vienna by keeping necessary ramps of the floor useful also for handicapped people. The government of the municipality of Vienna sees in this project one of the important steps to support and promote the circulation in the city for pedestrians and bicyclists and to reduce the motorized traffic and its harmful pollutions. The mould for the sophisticated structure of the columns was a new challenge for our team. At first glance the architectural drawings (elevations and sections) did not clearly show the actual shape of the columns. The column, composed of triangular surfaces revealed its optical and volume related properties only after a model had been produced by the CAD-design department. All data, derived from the 3-dimensional model was subsequently important information for the preparation of the offer. Dimensions of column • Length: 13 m • Cross section: 2.3 x 1.5 m • Weight: 22 t The two columns consist of around 3 metric tons of reinforcing steel and 18 m³ concrete. The transport was performed on time with company owned trucks over a distance of 233 km to Vienna Due to the local traffic situation, the mounting of the columns had to be managed in a fixed time frame between 10 p.m. and 6 a.m. Even though similar works had been carried out many times before by our team, it was additionally challenging since the whole operation took place during night hours. Long before traffic started again, our high-quality work was completed on time.
