How do I check BIM clash status with Bildstak?
Bildstak checks BIM clash status by reading your BCF coordination issues alongside the IFC model, joining each clash to the element it references — so you can query open, resolved and overdue clashes by discipline, package or element type in plain English.
Clash status in most workflows means exporting a BCF file from Navisworks or Solibri, importing it into a coordination platform, and manually updating a status spreadsheet. Bildstak replaces that loop with a live query layer.
How it works:
1. Connect your BCF source — Bildstak reads BCF files or connects to your coordination platform. 2. Connect the IFC model — Bildstak also reads the IFC model (direct file, Speckle stream, or Autodesk APS) and indexes every element by its GlobalID. 3. Join automatically — each BCF topic references the GlobalID of the element(s) it concerns. Bildstak joins them, so clash records are attached to the model elements they affect. 4. Query in plain English — ask "how many open clashes involve structural steel on Level 4?" or "which clashes have been open more than 30 days?" and get a cited answer. 5. Element Inspector — click any element in the 3D viewer and the Inspector shows every BCF issue raised against it, alongside the linked RFI, cost line or schedule activity.
Useful queries:
- Open clash count by discipline pair (structural vs. MEP, civil vs. architecture)
- Clashes older than a defined age threshold (overdue for resolution)
- Clashes on critical-path elements, cross-referenced against the P6 schedule
- Resolved clash audit trail for handover evidence
Bildstak does not replace your coordination authoring tool (Navisworks, Solibri, Revizto) — it federates the output so you can reason across it alongside the rest of the project data.
