IFC (Industry Foundation Classes) is an open, international data model developed by buildingSMART to facilitate interoperability in the architecture, engineering, and construction (AEC) industry. It standardizes the representation and exchange of building and construction data, enabling different software applications to communicate effectively. IFC is widely used in Building Information Modeling (BIM) workflows, allowing stakeholders to share and manage information throughout a building's lifecycle, from design and construction to operation and maintenance. By providing a common language for building data, IFC helps reduce errors, improve collaboration, and streamline project delivery.
