Markus Förster, department head for bridge building at LAP, explains “In coordination with the contractors, and taking into account the formwork system used, each of the 55 straight concreting sections of the arc were integrated into the 3D model precisely.” This allowed many potential problems to be solved in the planning phase, especially in critical areas such as intersections with very high reinforcement ratios.
Working out of Allplan Engineering allowed comprehensive, detailed virtual models to be created. Therefore, pre-tensioned cables, reinforcements, fixtures and their corresponding measurements were necessary elements to include in the model during the design phase. Numerous stresses had to be tested for wind, earthquakes, failure of tension cables, etc. The area where the bridge was being built, in addition to the unique design features, posed a tremendous challenge. In 2007, an official competition was advertised for this project and won by the engineering office Leonhardt, Andrä und Partner (LAP). With an arched span of 870 feet, a superstructure length of 1,368 feet and a height of 722 feet above the valley floor, the Tamina Bridge is the largest arched bridge in Switzerland.

#Allplan inc. software#
See from the customer’s point of view how Allplan Bridge and Engineering software was used in dynamic and endeavoring build projects, and how the ease of 3D modeling contributed tremendously to their success.ĭiscover new challenges and complex problems in customer problems solved with modern CAD software. Complex geometries including double-curved alignment and varying cross-sections can be easily created with the help of alphanumeric entries and stored formulas, making model configuration quick and efficient. The cross-section of the bridge as well as its variation along the alignment are described parametrically. The parametric model considers the plan alignment and the vertical profile of a road or a railroad. The unique model enables quick and efficient management of the changes that occur during the design process, saving both time and money.
