What is BIM?

Building Information Modeling is the name given to a software-based working method that brings together the design, construction and management of a building. In this context, BIM ensures a more intelligent use of data, for example to construct high-rise buildings faster and more ecologically. In this process, data on all aspects of construction are collected and managed over the entire life cycle of a building. In this way, BIM serves as an information bank for all those involved in the project, including construction companies, architects, engineers, and manufactures of elevators or facades.

As an essential part of the digitization of the construction industry, BIM pursues and enables several goals:

• Simplification of workflows
• Planning and cost security
• More accurate design decisions
• Optimization of buildings
• Anticipation of environmental impacts

BIM follows a specific cycle that continuously captures data at every point in time. This begins with the basics, the preliminary and detailed planning. This is followed by execution and documentation of the construction. This is followed by the collection of data during operation and finally demolition. If necessary, the building can also be redesigned, which starts the process again.

Numerous software now exist for the implementation of BIM, including:

• Allplan (Allplan GmbH)
• ArchiCAD (Graphisoft Group)
• BBSoft (B&B Ingenieurgesellschaft mbH)

In addition, there is also free software with individual functions, which includes FreeCAD or Openproject.
