IFC 4.3 Standard Approved as Final

buildingSMART International announced that ISO has officially ratified version IFC 4.3 as the definitive standard.

On 4 January, 2024, buildingSMART International communicated in London that ISO officially ratified version IFC 4.3 as the definitive standard. This milestone solidifies IFC 4.3 as the latest evolution of ISO 16739, an internationally recognized standard. ISO 16739 is the international standard defining the IFC format’s characteristics for data sharing in the BIM process.

IFC 4.3 pushes the construction industry towards the digitization of infrastructure in openBIM format. The new standard is designed to extend the benefits of IFC to “horizontal assets” and linear infrastructures, such as roads, railways, bridges, and aqueducts (see the article “IFC 4.3, the new IFC standard for exchanging openBIM models of infrastructural works“).
