• As the number of building elements and/orthe number of BIM authoring tools rises,the number of unsupported IFC2x3 itemsincreases too.

• Unsupported items start rising linearly, butsoon experience an exponential growth.

• Therefore, interoperability issues should beaddressed thoroughly in BIM ExecutionPlans prior to any modeling, in order toanticipate and minimize – at a lower cost –potential problems that may arise.

• The ideal (utopian?) situation would reveala flat number of unsupported items –tending to zero – regardless the number ofbuilding elements and/or BIM authoringtools that are employed in the project.
