Open BIM Program

OPEN BIM is a progressive, future-proof approach to AEC collaboration. It helps connect stakeholders such as software vendors, software users (architects, engineers and builders) as well as clients/owners to co-create great buildings. OPEN BIM is the only data management method that ensures long term data sovereignty for builders and operators.

OPEN BIM is based upon open standards such as IFC from buildingSMART. ALLPLAN and the Nemetschek Group fully support buildingSMART’s openBIM program. We are also fully dedicated to the high quality standards defined by our OPEN BIM Charter and represented by our OPEN BIM logo.


  • Interoperability between project stakeholders must not be used as grounds for competition.
  • Free choice of software in project work must be a basic right for any project stakeholder.
  • Proprietary format mandates must not be used to exclude candidates from project work.
  • Interoperability should be facilitated via development and support of open standards.
  • Rigorous testing and certification criteria is a must for quality support of open standards.
  • Industry stakeholders must publicly endorse and promote OPEN BIM in the AEC/O community.
