Which method of estimating cost provides a complete itemization of all costs incurred in construction?

The quantity survey method is the most comprehensive approach for estimating construction costs, providing a detailed itemization of all costs involved. This method assesses each component of the project, from labor and materials to overhead and profit, ensuring a thorough understanding of the total expenditure required. It involves meticulous measurement and evaluation of quantities, making it suitable for larger, more complex projects where precise budgeting is critical.

The quantity survey method facilitates a clear breakdown of costs, allowing for adjustments and evaluations at various stages of the project. This transparency can enhance financial planning and ensure that resources are allocated efficiently.

In contrast, other methods like the unit-in-place, direct cost, and comparative unit methods may not capture the complete spectrum of costs or might rely on averages and estimates rather than itemized calculations. While these methods can provide useful insights, they do not match the level of detail and accuracy achievable through the quantity survey method.
