# CWICR Assembly Builder ## Business Case ### Problem Statement Estimating repetitive elements requires: - Consistent item groupings - Reusable templates - Standard assemblies - Quick application ### Solution Build and manage assemblies of CWICR work items that can be applied as templates to speed up estimating and ensure completeness. ### Business Value - **Speed** - Apply complete assemblies quickly - **Consistency** - Standard item groupings - **Completeness** - No missed items - **Reusability** - Template library ## Technical Implementation ```python import pandas as pd import json from typing import Dict, Any, List, Optional from dataclasses import dataclass, field from enum import Enum from datetime import datetime class AssemblyType(Enum): """Types of assemblies."""
