Which term describes the calculations made to estimate the quantity of materials for a project?

The term that describes the calculations made to estimate the quantity of materials for a project is "takeoff." In construction, a takeoff refers to the process where quantities of materials are measured from construction drawings and project specifications. These quantities are crucial for preparing accurate cost estimates and bids. A takeoff ensures that all necessary materials are accounted for, enabling project managers and estimators to maintain resource efficiency and budget oversight throughout the life of the project.

In contrast, the other terms pertain to different aspects of construction documentation. A breakdown typically relates to the division of project costs or tasks into smaller, manageable sections. Listing might refer to a simple enumeration of items, while specification usually covers detailed descriptions of materials, workmanship, and standards that will be used in the construction project. Each term serves its own purpose within the construction documentation process, but "takeoff" specifically addresses the estimation of material quantities, making it the most accurate term in this context.
