The BIM landscape is constantly evolving, and 2025 brings significant updates to industry standards that will impact how we model, document, and deliver projects. Understanding these changes is crucial for staying compliant and competitive in today's market.
ISO 19650 Updates
The ISO 19650 series, which governs information management in BIM projects, has been updated with new requirements for data quality and exchange. The 2025 revisions emphasize:
- Enhanced data validation requirements for model exchanges
- Stricter requirements for common data environments (CDE)
- New guidelines for AI-assisted model generation
- Updated information delivery planning templates
IFC 4.3 Adoption Requirements
Industry Foundation Classes (IFC) version 4.3 is now the recommended standard for model exchanges. This update includes significant improvements in:
MEP Systems
Enhanced representation of mechanical, electrical, and plumbing systems with better connectivity modeling.
Structural Elements
Improved structural analysis data exchange and reinforcement detailing capabilities.
Property Sets
Expanded property definitions for better data richness and interoperability.
Sustainability Reporting Standards
New requirements for embedded sustainability data in BIM models are now mandatory for public projects in many jurisdictions. Models must include:
- Embodied carbon data for all major building elements
- Energy performance parameters linked to model geometry
- Lifecycle assessment data in standardized formats
What This Means for Your Projects
These updates require immediate attention. Projects starting in 2025 must comply with the new standards, and existing projects may need updates to meet revised requirements. Key action items include:
- Update your BIM execution plans (BEP) to reflect new requirements
- Train your team on IFC 4.3 export and validation procedures
- Implement sustainability data collection workflows
- Review and update your CDE configuration for compliance
Staying Compliant
While these updates may seem overwhelming, they represent important steps toward better interoperability, data quality, and sustainability in the AEC industry. Organizations that adapt quickly will have a competitive advantage, while those that delay may face compliance issues and project delays.
