BIM Cost Estimation with DDC CWICR
Generate accurate cost estimates from BIM models using AI classification and the DDC CWICR construction cost database.
Business Case
Problem: Traditional cost estimation:
- Manual and time-consuming (weeks for detailed estimate)
- Subjective and inconsistent between estimators
- Requires specialized knowledge
- Difficult to update with design changes
Solution: Automated BIM-to-cost pipeline:
- Extract quantities directly from model
- AI classifies elements to work items
- Vector search finds matching prices in CWICR
- Complete estimate in hours, not weeks
ROI: 80% reduction in estimation time, consistent methodology
