We use our years of experience in 3D modelling of complex steel structures to work with BIM models. We use our own tools for bulk management of attributes assigned to individual model elements. We have tested our ability to process the design of a minor bridge with an adjacent road in BIM mode on a pilot project, which we processed according to Czech regulations. The model of the bridge structure was prepared in Siemens NX, the model of the connecting road was prepared in Civil 3D. The work on the overall BIM model of the structure was tested in BIMvision (datacomp) and DESITE BIM (thinkproject).
