Definition
IFC, short for Industry Foundation Classes, is an open, standardised file format for sharing BIM data between different software programs. It lets a building model created in one tool be opened and understood in another, without losing the information it contains.
Because construction projects involve many teams using different software, IFC provides a neutral common language so everyone can exchange models reliably. It is a cornerstone of open collaboration in BIM.
In simple terms, IFC is a universal format that lets BIM models move freely between programs while keeping their data intact.
How It Works
IFC defines a structured way to describe building elements, such as walls, doors, and spaces, along with their properties and relationships. When a model is exported to IFC, this information is stored in a standard structure that any compliant software can read.
This means a model authored in one BIM tool can be shared with collaborators who use different software, supporting coordination, review, and analysis. IFC is maintained as an open standard, which keeps it vendor-neutral and widely supported.
Applications
IFC is used across architecture, engineering, and construction for model exchange and collaboration. It supports design coordination between disciplines, clash detection, handover to owners, and long-term data preservation, especially on projects that use software from multiple vendors.
Benefits
- Open, vendor-neutral sharing of BIM data.
- Reliable model exchange between different software.
- Better collaboration across disciplines.
- Preserves element data and relationships.
- A long-term, standardised record of a project.

Frequently Asked Questions
What is IFC used for?
IFC is used to share BIM models between different software so teams can collaborate, coordinate, and preserve building data.
Why is IFC important in BIM?
It provides an open, neutral format so models can move between programs without losing information, enabling open collaboration.
Is IFC tied to one software?
No. IFC is an open, vendor-neutral standard supported by many BIM tools.
What information does IFC store?
It stores building elements along with their properties and relationships, not just their geometry.
