Problem Statement
Estimate creation challenges: Complex cost structures Multiple cost categories Markup calculations Format requirements vary
Solution
Structured estimate builder that creates professional construction estimates with proper cost categorization, markups, and export capabilities.
Technical Implementation

Quick Start
# Create estimate estimate = EstimateBuilder("Office Building A", "PRJ-2024-001") # Add line items estimate.add_item("01.01", "Site Preparation", 5000, "SF", 2.50, CostCategory.OTHER) estimate.add_item("03.01", "Concrete Foundation", 200, "CY", 350, CostCategory.MATERIAL) estimate.add_item("03.02", "Foundation Formwork", 1500, "SF", 8.50, CostCategory.LABOR) estimate.add_item("05.01", "Structural Steel", 50, "TON", 4500, CostCategory.SUBCONTRACTOR) # Set markups estimate.set_standard_markups(overhead=0.15, profit=0.10, contingency=0.05) # Calculate total result = estimate.calculate_total() print(f"Direct Cost: ${result['cost_summary']['direct_cost']:,.2f}") print(f"Grand Total: ${result['grand_total']:,.2f}")
1. Cost by Category
summary = estimate.get_cost_summary() print(f"Labor: ${summary.labor:,.2f}") print(f"Material: ${summary.material:,.2f}")
2. Export to Excel
estimate.export_to_excel("estimate_output.xlsx")
3. Validate Estimate
issues = estimate.validate() for issue in issues: print(f"Warning: {issue}")
