Quantity takeoff

Measurement of work quantities from project information for estimating, procurement, or cost review.

Why it matters

Quantities need a defined drawing set and measurement method. They do not by themselves establish installed cost, which also depends on labor, waste, access, and project conditions.

In practice

A project example

A wall-area takeoff supports a finish estimate, but high ceilings and occupied-space phasing affect the installation cost.
