A quantity takeoff measures physical work from the drawings, such as cubic yards of concrete, linear feet of pipe, or fixture counts. A cost estimate applies labor, material, equipment, subcontractor, and other project costs to defined quantities and scope. Choose a takeoff when you will price the work yourself; choose a priced estimate when you need a documented cost model.

An estimator needs the latest available drawings, specifications, addenda, bid instructions, scope boundaries, project location, and required pricing breakdown. Incomplete documents do not always prevent an estimate, but missing information should be identified and handled through exclusions, assumptions, allowances, or requests for clarification.

Construction takeoffs use units that match how work is measured, purchased, installed, or priced. Counts suit fixtures and equipment; linear feet suit length-based work; square feet suit surfaces; cubic units suit volume; and pounds or tons suit weight-based materials. The item description, unit, location, and measurement rule must be read together.
