In my master's thesis I deal with the integration of two different authoring platforms used in the process of building information modeling (BIM) of infrastructure objects. I focus mainly on the integration of the Civil 3D and Revit computer programs, which remain the most commonly used programs in the design of linear (Civil 3D) and discrete (Revit) parametric objects. I use an add-on for Revit, called Dynamo, which serves as a connecting link and a visual programming tool, and Dynamo package - CivilConnection, which allows the establishment of a direct, dynamic, and automated connection between open sessions of both authoring platforms. The master's thesis is divided into six major sections, with the second, third and fourth being of a more theoretical nature, while the fifth presents the workflow of transferring geometric and non-geometric information of the selected infrastructure objects between the two authoring platforms. The workflow (including the example) is divided into three parts: roles and responsibilities in the infrastructure BIM project, technology, and a work process with subprocesses. Due to the different natures of infrastructure objects, the presented workflow serves only as a description of the general steps that describe potential usage of the Dynamo and CivilConnection package in the process of connecting Civil 3D and Revit in infrastructure design. The workflow is demonstrated with an example of a box-profile bridge structure.
