What does the quantity-survey method estimate?

The quantity-survey method is focused on estimating the cost of construction by analyzing the individual components of a project. This detailed approach involves breaking down the project into various elements, such as materials, labor, and overhead costs. Each component is quantified and priced, leading to a comprehensive estimation of total construction costs. This method is commonly used in the construction industry to provide accurate and detailed budgets, ensuring that all aspects of the construction process are considered.

The other choices address different aspects of real estate valuation or income potential, which are not the focus of the quantity-survey method. For instance, estimating market value pertains to overall property assessment rather than the specifics of construction costs. Similarly, determining depreciation rates involves understanding the reduction in value over time, and evaluating rental income potential relates to projected earnings from a property, which are different areas of real estate analysis.
