Building Information Modelling (BIM) is an indispensable design requirement today. The new legislation also makes its use mandatory within certain limits. At its core, design is not only done in a model, but all elements of the model contain attributes and information. This makes it easier to extract, summarise and operate the information. If all disciplines work at the same level of BIM detail, errors and conflicts can be minimised.
Traditional building design relied largely on two-dimensional technical drawings (plans, facades, sections, etc.). Building information modelling extends the three primary spatial dimensions (width, height and depth), including time information (4D BIM), cost (5D BIM), asset management, sustainability, etc. BIM therefore not only covers geometry, but also includes spatial relationships, spatial information, quantities and properties of building elements (e.g. manufacturers' data) and allows for a wide range of collaborative processes related to the construction project, from initial design to construction and throughout the life of the building.
