It contains eight conveyor lines distributed over two floors. Altogether, seven railway lines, one small river, one road bridge and three roads had to be bridged over. Hence, the bridge had to be designed with the impressive dimensions of 100 m length, 17 m width and 21 m height. The most challenging area to construct was the edge of the bridge where the structure cantilevers up to 16 m and the field next to it spans over 40 m. The bracing is mainly constructed by frames. Additional struts are added to the columns below the superstructure. In order to meet fire protection standards and to avoid the necessity of a fireproof coating on the exterior components, several columns are overdesigned at fire rating level R30. In addition to the challenging spatial conditions, the BMW production process couldn’t be influenced. Because of the narrow time slot for installation, large parts of the steel structure had to be prefabricated. Therefore, the 3D bridge model was calculated for all individual assembly states. To guarantee a smooth operation of the conveyor technology elements, an exact prediction of the building movements was required and accomplished using SCIA Engineer.
