# CWICR Quantity Matcher ## Business Case ### Problem Statement BIM exports contain quantities but: - Element categories don't match cost codes - Manual mapping is error-prone - Different naming conventions - Need consistent code assignment ### Solution Intelligent matching of BIM element quantities to CWICR work items using category mapping, semantic matching, and rule-based assignment. ### Business Value - **Automation** - Reduce manual mapping effort - **Consistency** - Standard code assignment - **Accuracy** - Validated quantity linkage - **Integration** - BIM-to-cost data flow ## Technical Implementation ```python import pandas as pd import numpy as np from typing import Dict, Any, List, Optional, Tuple from dataclasses import dataclass, field from enum import Enum import re from difflib import SequenceMatcher class MatchMethod(Enum): """Methods for matching BIM elements to work items."""
