The best way to understand BIM is to explore how the industry evaluates it.
Autodesk, the developer behind widely-used BIM software platforms like Revit and AutoCAD Civil 3D, views BIM as an information-centric platform. It is a process built on intelligent models that facilitates accurate design, construction, and project operational data, making buildings and infrastructure both accessible and manageable. The “I” in BIM stands for information, which is essential for project success. Having detailed data within the model ensures that every team member operates on the same platform, supporting the project through every phase—from concept and construction documentation to ongoing maintenance.
Graphisoft, known for ArchiCAD—one of the pioneering BIM software platforms—defines BIM as the process of creating and managing 3D virtual building models along with collecting building data. According to Graphisoft, BIM fundamentally begins with the three-dimensional digital model of the building.
Similar to information, models are at the heart of the BIM workflow. They form the foundation for the entire project by representing all building components and their virtual counterparts, while also enabling practical applications of these elements.
Bentley offers modeling and project delivery tools such as AECOsim Building Designer and ProjectWise. The company emphasizes that BIM methods enhance project collaboration and introduce new controls suitable for projects of any scale. By transforming how information is applied and shared, BIM enables teams to achieve complete data exchange, which leads to better project outcomes and increased accuracy throughout the project lifecycle.
Reviewing the definitions from these three leading BIM software companies reveals that each emphasizes a different aspect of BIM. While their perspectives have slight differences and limitations, together they provide a comprehensive understanding of BIM’s true meaning from multiple angles.
