The Tower of Babel illustrates the importance of enhancing interoperability through standardized data. The solution to the problems of data silo is IFC and bSDD (buildingSMART Data Directory). Using bSDD simplifies data input and dramatically accelerates interoperability. In BIM, the key to data integration is the exchange of attribute information both within and across sectors. The openBIM® workflow, which facilitates data integration, utilizes world-class standards in IFC and BIM technology. It is crucial to fully leverage the technical standards that support IFC when building workflows. Relying on specific software or closed technologies is very risky, and we must always consider “sustainability.” Workflows must be open and highly interoperable to ensure that even those with only construction knowledge can effectively use BIM.
