For a typical residential building, cost estimation involves calculating thee quantities of concrete, steel, and text materials. Labor costs are estimated based on project duration and workforce rates. For instance, if thee project requires 200 cubic meters of concrete at $100 per cubic meter, material costs are $20,000.
