What is a common use of unit use calculation in cost estimation?

The correct focus of unit use calculation in cost estimation lies in its ability to provide a quick reference for preliminary budgeting. This method allows architects and cost estimators to use established unit costs based on historical data and similar projects to generate initial cost estimates for new projects efficiently. By breaking down the project into quantifiable units, such as square footage or volume, estimators can quickly assess approximate costs, aiding in decision-making and budget approvals early in the planning process.

Using unit costs helps to streamline the budgeting process and offers a reliable framework for estimating without needing exhaustive detailed analyses at this stage.
