# 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 ## System Architecture ``` ┌──────────────────────────────────────────────────────────────────────────┐ │ BIM TO COST ESTIMATION PIPELINE │ ├─────────────────────────────��────────────────────────────────────────────┤ │ │ │ ┌─────────┐ ┌─────────┐ ┌─────────┐ ┌─────────────────┐ │ │ │ BIM │ │ DDC │ │ AI │ │ DDC CWICR │ │ │ │ Model │────►│Converter│────►│ LLM │────►│ Vector Search │ │ │ │.rvt/.ifc│ │ │ │ │ │ (Qdrant) │ │ │ └─────────┘ └─────────┘ └─────────┘ └─────────────────┘ │ │ │ │ │ │ │ ...
