Construction Takeoff Explained

What Are Construction Takeoff Services?

Construction takeoff services measure materials, components, assemblies, areas, lengths, volumes, and item counts from project drawings before pricing, procurement, budgeting, or bid submission.

The takeoff can be organized by trade, drawing discipline, work package, building area, cost code, material type, or the reporting structure used by your estimating and procurement teams.

Quick Answer

Construction takeoff services convert drawings into measurable quantities. The final output can include material lists, trade summaries, marked-up drawings, drawing references, measurement units, assumptions, exclusions, and editable quantity reports.
