BIM can support progress payment evidence by connecting quantities, installed status, inspection records, photos, and approved work zones. The model becomes a spatial index for what has been completed and verified.
Why This Matters
Payment disputes often arise when quantity claims and site evidence do not align. BIM can improve clarity if the model status is controlled and linked to field proof.
Practical Guidance
Define Pay Items: Map model elements or zones to payment items carefully. Not every model element is a payment unit.
Separate Modeled and Installed: A modeled item is not automatically installed. Status must be verified.
Attach Evidence: Link inspection results, photos, delivery records, and acceptance notes.
Use Cutoff Dates: Progress claims need a clear model version and status date.
Checklist
- Map model elements or zones to payment items
- Track installed and accepted status separately
- Attach field evidence for claimed progress
- Use clear model versions and cutoff dates
LUA BIM LABS Insight
BIM can support payment confidence, but only when status is evidence-based. Geometry alone is not proof of progress.
