What type of costing is based on cost per square footage and is often used in early project stages?

The type of costing that is based on cost per square footage and is commonly used in the early stages of a project is indeed the area calculation cost estimate. This method allows architects and project managers to quickly assess the overall budget for a project based on the size of the building or space being designed. It provides a straightforward way to calculate costs by applying a pre-determined square footage rate, making it particularly useful when detailed design information is not yet available.

Area calculation cost estimates are practical because they facilitate initial budget discussions and help stakeholders make informed decisions about feasibility before any detailed plans are developed. By focusing on the area, this method simplifies the complexity involved in early cost assessments and allows for rapid comparisons between different design options and project scopes.

Other methods mentioned, while relevant in the construction costing context, serve different purposes. For instance, elemental cost estimates break down costs into components or systems, which typically requires more detailed information than what is usually available in early project stages. Class B estimates are more refined than preliminary estimates but still are not as straightforward as area calculation estimates. Life-cycle cost analysis evaluates the total cost of a building over its lifespan rather than providing an initial cost estimate based on size. Therefore, the area calculation cost estimate is the best fit for early
