Aprende Material Quantities and Cost Estimation | Architectural Data Analysis with Python

Estimating material quantities and costs is a crucial part of any building project. This process, known as material takeoff, involves determining how much of each material—such as concrete, steel, or glass—is required, and then estimating the total cost based on current unit prices. By using Python, you can automate these calculations, reducing manual errors and saving time. You will learn how to represent material quantities and unit costs using dictionaries, and how to compute total costs by combining these data structures.


              12345678910111213
            
# Dictionary storing quantities of materials needed for a project (in cubic meters or tons)
material_quantities = {
    "Concrete": 120,
    "Steel": 30,
    "Glass": 45
}

# Dictionary storing unit costs for each material (in dollars per unit)
unit_costs = {
    "Concrete": 100,
    "Steel": 800,
    "Glass": 50
}

To estimate the total cost of materials for a project, you need to multiply each material's quantity by its unit cost. Using the dictionaries from before, you can loop through each material, retrieve its quantity and corresponding unit cost, multiply them, and sum the results for a total estimate. This approach makes it easy to update quantities or prices and quickly recalculate the total cost.


              12345678910
            
def estimate_total_cost(quantities, costs):
    total = 0
    for material, quantity in quantities.items():
        unit_cost = costs.get(material, 0)
        total += quantity * unit_cost
    return total

# Example usage:
total_cost = estimate_total_cost(material_quantities, unit_costs)
print("Total estimated material cost: $", total_cost)
