How is a quantity survey used in construction?

A quantity survey is primarily used in construction to determine the quantities of materials needed for a project. This process involves meticulous measurement and estimation of materials required for various aspects of construction, such as concrete, steel, timber, and other components. The quantity survey helps project managers and estimators create accurate budgets, prepare cost estimates, and understand resource allocations. By having a clear understanding of material quantities, construction teams can minimize waste, streamline procurement processes, and ensure that projects are completed on time and within budget.

The other options focus on different aspects of construction and project management. For instance, environmental impact assessments, zoning analysis, and establishing legal property boundaries serve distinct functions and require separate expertise and methodologies outside the scope of what a quantity survey addresses.
