Civil 3D Quantity Takeoff

Use this skill when working with quantity takeoff (QTO) - computing material volumes, assigning pay items, defining QTO criteria, generating quantity reports, or calculating earthwork cut/fill volumes.

Quantity Takeoff Overview

Quantity takeoff in Civil 3D connects design objects to cost estimation:

• QTO Criteria = rules mapping corridor shapes/surfaces to material definitions
• Material Lists = computed volumes per sample line group from corridor cross-sections
• Pay Items = cost line items (from .csv pay item files) assigned to Civil 3D objects
• Quantity Reports = XML-based summary or detailed reports of pay item quantities

QTO Criteria and Material Lists

Loading QTO Criteria into a Sample Line Group

Material computation starts by importing QTO criteria into a sample line group. The criteria define which corridor shapes and surfaces produce material volumes.
