What It Means

BIM Collaboration Format (BCF) is an open standard file format developed by buildingSMART that allows project teams to exchange issue-related data linked to 3D models without exchanging the full model itself.

BCF is commonly used to communicate design issues, coordination conflicts, comments, and review feedback between stakeholders, especially across different BIM platforms. It includes:

• Viewpoints (camera angles) and element references
• Issue descriptions and metadata (status, author, priority, due date)
• Snapshots or annotations
• Links to IFC elements

BCF files are typically used in tandem with IFC models to support OpenBIM coordination workflows.

Why It Matters

In complex design and construction projects, tracking and resolving issues efficiently is critical. BCF streamlines that process by:

• Enabling model-based issue tracking without sharing entire BIM files
• Supporting platform-neutral communication
• Keeping a visual record of coordination conflicts and review feedback
• Enhancing transparency and reducing reliance on emails or disconnected screenshots

BCF helps design and construction teams work more collaboratively, even when using different software tools.

Best Practices

• Link BCF issues directly to relevant IFC elements or model locations
• Assign clear titles, priorities, and responsible parties to each issue
• Use BCF-compatible tools (e.g., BIMcollab, Solibri, Navisworks with plugins)
• Maintain a central BCF coordination hub or issue tracker
• Regularly review and close out resolved issues during coordination meetings

Real-World Use

During the design coordination phase of a mixed-use tower, clash detection was performed using certain BIM software, and all identified issues were exported as BCF files. The architectural, structural, and MEP teams then imported these issues into their respective platforms, each able to view and respond without needing to open the same BIM software or work on a centralized model.

This BCF-driven workflow reduced meeting time, improved issue ownership, and created a clear audit trail of resolved and pending design coordination items.

Limitations

• BCF files do not contain the 3D model geometry. Only references to IFC elements or viewpoints
• Requires setup of compatible software and version alignment
• Limited to issue management; not a replacement for full CDE or BIM data
• Inconsistent use or missing metadata can lead to confusion
• Some proprietary tools offer only partial BCF support

In Simple Terms

BCF is like a to-do list for your 3D model. Instead of sending screenshots or full files, you send a pinpointed issue with notes and a camera angle so others can fix it fast.

How D.TO Helps

D.TO supports coordination workflows that generate consistent, structured detailing logic. By reducing ambiguity in transitions, assemblies, and interface conditions during the DD and CD phases, D.TO helps lower the number of preventable issues flagged.
