BIM Level 2 connect many interdisciplinary and collaborative Federated models. Models consist of both 3D geometric and non-graphical data, they are developed by individual project participants during the project life cycle, using Common Data Environment (CDE) to ensure a coordinated information management process.

In the example (fig 3) we see a Federated model that includes parts of architecture, structures, engineering systems. Specialized software is used to create such a model. In this case, the manufacturer’s add-on Wavin Revit was used, which means that the model has the exact geometry and all the manufacturer’s attribute information.

Usually used general data environments, which run on cloud based application this ensures the availability of information from any location and using a variety of devices – computers, smart devices.

For successful data sharing, procedures are established, defining the methods how the data is shared or used by all project participants. The principles of data exchange are based on various standards, normative documents, such as the ISO 19650 group, IFC (Industry Foundation Classes), COBie (Construction Operations Building Information Exchange) and others.

BIM models are stored as files. Later using software, central storage additional applications, appropriate models are used to solve different tasks, for example, to calculate estimates, to plan production, to manage logistics and etc. BIM process includes all stages of a building’s life cycle, and allows gradually to develop an information model, to move from a project information model to an asset information model.

BIM 2 level – managed BIM environment. 3D models with data and other related information are integrated into a single information model that can be completed by engineers individually.
