The digital transformation of the construction industry has been driven in large part by Building Information Modeling (BIM). As BIM adoption grows, the tools and platforms that support BIM workflows have become more diverse. Two prominent approaches stand out: OpenBIM och Autodesk Construction Cloud BIM (ACC). While both aim to streamline design, collaboration, and construction processes, they differ significantly in philosophy, implementation, and interoperability.
OpenBIM is a universal approach to collaborative design and construction that uses open standards such as IFC (Industry Foundation Classes), BCF (BIM Collaboration Format), and IDM (Information Delivery Manual). It is supported by buildingSMART and a wide range of software vendors to ensure that data is not locked into proprietary formats.
What is OpenBIM?
OpenBIM is a universal approach to collaborative design and construction that uses open standards such as IFC (Industry Foundation Classes), BCF (BIM Collaboration Format), and IDM (Information Delivery Manual). It is supported by buildingSMART and a wide range of software vendors to ensure that data is not locked into proprietary formats.
Key Features:
- Vendor-neutral: Developed around open standards, OpenBIM allows for interoperability across various BIM tools like Archicad, Revit, Tekla, and StreamBIM.
- Longevity and flexibility: Ensures data can be used long-term, independent of any single software ecosystem.
- Focus on collaboration: Supports multidisciplinary teams using different tools.
- Transparency: Enables auditability and quality assurance across the project lifecycle.
Advantages:
- Freedom from vendor lock-in
- Easier collaboration across software ecosystems
- Better data portability for long-term facility management
What is Autodesk Construction Cloud BIM (ACC)?
Autodesk Construction Cloud BIM (ACC) is a cloud-based suite of construction management tools that integrate tightly with Autodesk’s BIM software ecosystem, including Revit, AutoCAD, Navisworks, and BIM 360. ACC BIM focuses on unifying workflows from design to construction within a single platform.
Key Features:
- Seamless integration with Autodesk tools: Native support for Revit, Civil 3D, and AutoCAD files.
- Cloud-based collaboration: Real-time updates, issue tracking, RFIs, and document control.
- Advanced analytics and dashboards: Centralized data environment with insights into cost, schedule, and quality.
- Project lifecycle management: Connects design, construction, and operations in a single platform.
Advantages:
- Highly integrated user experience for Autodesk users
- Fast deployment with ready-to-use templates
- Robust support and extensive documentation
- Deep feature set for field coordination and model-based workflows
Head to head comparison
Which One Should You Choose?
- Choose OpenBIM if:
- You need to collaborate with multiple stakeholders using different BIM tools.
- Long-term data accessibility and open standards are a priority.
- You want to reduce reliance on a single software vendor.
- Choose ACC BIM if:
- Your team already uses Revit or other Autodesk products or your open BIM software does not have a Revit or Autodesk Plugin.
- You want a streamlined, all-in-one solution with integrated project controls.
- You value a polished, tightly integrated user experience.
Conclusion
OpenBIM and ACC BIM represent two fundamentally different approaches to managing BIM workflows. OpenBIM champions interoperability and openness, while ACC BIM offers a closed but cohesive platform tailored for Autodesk users. The right choice depends on your project goals, team composition, and long-term data strategy.
Both can deliver powerful outcomes — the key is aligning your technology strategy with your organizational needs and project requirements.
