Quantity Takeoff (QTO)

Quantity takeoff (QTO) is the process of measuring and counting everything shown in a drawing set — linear feet of pipe, square footage of drywall, number of fixtures — to produce the quantities an estimate is built on.

It answers “how much of everything is in this job?” before any pricing happens. Estimators pull counts, lengths, areas, and volumes from plans, elevations, details, and schedules so the estimate has a measurable basis.

Quantity takeoff is broader than material takeoff. QTO covers materials, labor-driving quantities, and other measurable scope items that later get priced with unit costs or assemblies.

Good quantity takeoff depends on accurate drawings, correct scale, trade knowledge, and careful review of specifications and addenda.
