Building Information Modeling (BIM) characterizes the construction industry and is increasingly being required globally for the contracting of construction services. The aim is to deliver construction projects efficiently. This requires transparency, good communication, and cross-discipline cooperation. The focus is on the digital building model, which contains all information from all disciplines.

BIM is not software, but rather is a working method for the construction industry where people, processes, and tools interact in a goal-oriented manner. Theoretically this sounds simple, but it presents a major challenge for planners. Exchanging CAD data, in particular, has proven to be faulty in the past with conventional working methods. Exchanging different file formats of various software between disciplines has often led to losses of information.


A neutral data format was developed to ensure a smooth BIM process: the Industry Foundation Classes (IFC) format. In the following ten sections, read about the powerful tool the planners at Stücheli Architekten from Switzerland use and how they efficiently process BIM projects with the help of the IFC data exchange.


  • Improved interoperability through optimized interfaces
  • Constant optimization and continued development
  • IFC as a digital catalyst for BIM
  • Cross-manufacturer and cross-software communication
  • Supports numerous applications
  • Filtering key information with subsets
  • Standardization of the BIM workflow
  • Simplified data exchange in the IFC data model with BCF
  • Internationally accepted language for open data exchange
  • IFC and OpenBIM as an essential planning component

Data exchange has now taken on a central role due to the change in cooperation in building projects associated with BIM. The actual added value of BIM can only be generated if the openBIM method is used. For only if cross-software data exchange is possible can the individual models of different disciplines be compared with each other in the central BIM model.
