Creating a Better Built Environment

IFC4 and ISO 16739

After 6 years of intensive and hard work and many review and quality assurance cycles, the next generation of buildingSMART’s flagship international standard IFC has been released .

This has been a collaborative work by buildingSMART’s Model Support Group with all other contributors:

This marks the beginning of a new era of openBIM collaboration. At the official IFC4 landing page you will find a “what’s new” presentation, showing some highlights of the new release.

Of course, the work hasn’t been finished yet, the next important steps are:

  • development of the first buildingSMART International Model View Definitions MVD, as the baseline for full IFC4 implementation efforts, starting with the IFC4 equivalences to the current coordination view 2.0, and other model views focusing on the new features, such as “product catalogues”;
  • support and orchestrate the IFC4 software interface implementation work for the major model views;
  • guide and support the migration process from using IFC2x3 to using IFC4 based solutions

Those steps take time. In the meantime, efforts will concentrate on the ongoing IFC2x3 certification process where first achievements have been acknowledged by granting export certificates, see

These products can then be used by design and construction professionals with higher quality for better work right away.
