Application of BIM in bridge construction

Abstract

The spread of digital technologies in the field of engineering led to the invention of various methods for digitization processes. The use of Building Information Model (BIM) is already expanding to the application for infrastructure objects. Therefore, a need for the practical implementation of a BIM for each type of the specific objects is sufficient. In the current research, the main objective is to present an optimal technique for the application of BIM for built bridges. Based on the project documentation and field measurements of a bridge, a digital model must be created using Revit software. To investigate the achievements so far, some scientific articles and proposed technologies have been analyzed. How is BIM for infrastructure management already developed in many countries? What is a more detailed methodology called bridge information model (BrIM)? Another important question is how to digitize old objects in a simple and fast way. The procedures of data acquisition, georeferencing and modeling have been implemented and described. All successive steps from surveying an area to visualization and data transfer are presented in the study. The TLS and aerial photographs were merged and transferred into a point cloud, which served as a source for modeling. Revit software is used to create a bridge. Attribute data was taken from the project documentation, and the model of the newly built bridge on the old federal road B96 was transferred to a BIM. For the bridge on the new federal road B96, the inclination of the bridge body and the rotation around the center axis were modeled using an add-on for Revit called SOFiSTiK.
