Definition
In Solibri, BCF Coordination represents the collaborative issue gateway. BIM Collaboration Format (BCF) stores coordinate camera views and comments, syncing issues directly to Revit or Archicad panels.
By checking and exporting BCF zip archives, coordinators avoid coordinate offsets and link issues directly to geometry IDs.
Why it matters
Streamlines team communication by focusing solely on coordinate conflict resolution without sharing massive model databases. Without it, teams must coordinate using messy screenshots and spreadsheets, losing tracking histories.
Technical Deep Dive & Core Mechanics
BCF Issue Management (Solibri) operates on a federated model—a composite of separately authored discipline models merged in a neutral viewing environment. The federation process transforms each source model's local coordinate system into a shared project coordinate system, using origin offsets and rotation angles defined in the project's coordination protocol. Mismatches in these transformation parameters cause apparent model misalignments that masquerade as genuine clashes.
Clash detection algorithms evaluate BCF Issue Management (Solibri) by testing spatial overlap between bounding volumes (axis-aligned bounding boxes) as a first pass, then refining with exact geometric intersection tests for candidate pairs. The first-pass AABB test is computationally cheap (O(n log n) with spatial hashing), but the exact geometry test is expensive—particularly for curved elements like pipes, ducts, and structural members with complex profiles. Tolerance settings control whether near-misses are flagged, and grouping rules collapse related clashes (e.g., all clashes between the same two pipes) into single actionable items.
Step-by-Step Professional Implementation
Deploying BCF Issue Management (Solibri) in a multi-discipline coordination workflow demands structured federation and issue tracking:
- Prepare the Federated Model: Import or link discipline models (architectural, structural, MEP) into the coordination environment. Verify that shared coordinates, project base points, and true north alignment are consistent across all source models.
- Configure Clash Detection Rules: When running BCF Issue Management (Solibri), define tolerance thresholds, clash grouping rules, and priority filters. Separate hard clashes (physical intersections) from clearance violations to streamline review workflows.
- Issue Tracking via BCF: Export detected issues as BCF (BIM Collaboration Format) topics linked to specific viewpoints. Assign responsibilities and deadlines, then distribute to discipline leads through the project's common data environment (CDE).
- Verify Resolution and Close Out: After modelers resolve flagged issues, re-run clash detection to confirm clearance. Archive resolved topics and generate coordination reports for milestone documentation and audit trails.
Advanced Troubleshooting & Error Diagnostics
Common issues in BCF Issue Management (Solibri) coordination workflows and their resolutions:
- False clash results from coordinate misalignment: Hundreds of clashes reported between models that should be spatially aligned. Resolution: Compare the origin points and shared coordinates of all source models. Even a 1mm offset produces systematic false clashes across the entire model. Re-export the source models with corrected shared coordinates and re-run the detection.
- BCF issues not visible in authoring tool: BCF topics created during BCF Issue Management (Solibri) review don't show the correct viewpoint when opened in the BIM authoring tool. Resolution: Verify that the BCF file uses the same coordinate system as the authoring tool. Some tools interpret BCF camera positions differently (local vs. shared coordinates). Test with a single known-position issue to calibrate the viewpoint mapping.
- Model performance degrades with large federated models: Navigation becomes sluggish when reviewing BCF Issue Management (Solibri) in a federation with many disciplines. Resolution: Use section boxes to limit the visible scope. Convert models to optimized formats (NWC cache files for Navisworks, lightweight IFC for web viewers). Disable element categories not relevant to the current review (furniture, plumbing fixtures) to reduce rendering load.
Cross-Discipline Collaboration & Handoff
As a coordination tool, BCF Issue Management (Solibri) operates at the intersection of all project disciplines. Effective cross-discipline workflows require:
- Model Federation Protocol: Establish a documented schedule for model drops from each discipline (architecture, structure, MEP, civil). Define file formats, coordinate-system conventions, and naming standards that all contributors follow when publishing to the common data environment.
- BCF-Based Issue Communication: Export clash and coordination issues as BCF topics with embedded viewpoints, screenshots, and responsibility assignments. This open standard allows issue tracking to flow between coordination software, BIM authoring tools, and project management platforms without platform lock-in.
- Resolution Verification Loop: After discipline modelers address flagged issues, re-federate updated models and re-run detection rules to confirm clearance. Maintain a living coordination log that records issue history, resolution dates, and any accepted deviations from design intent.
Common pitfalls
- Modifying model element GUIDs, breaking BCF camera targets
- Skipping assignees, leaving issues unresolved.

Practical Workflow Tips
From coordination meeting rooms to the model, practical tips for BCF Issue Management (Solibri):
- Run clashes in batches by discipline pair: Rather than running "everything vs. everything," set up discipline-pair tests. This organizes results into manageable groups that can be assigned to specific teams.
- Time-stamp every model version: Include the export date in filenames. Stale models in the federation are the single most common source of wasted coordination time.
- Create saved viewpoints for recurring meetings: Set up navigation viewpoints that match coordination zones. Consistent viewpoints ensure no area is accidentally skipped across meetings.
- Assign BCF issues to individuals, not teams: Issues assigned to "the MEP team" tend to be delayed. Assigning each BCF Issue Management (Solibri) issue to a named individual produces faster resolution.
