Traditionally, construction cost estimators have used paper-based methods to perform quantity takeoff. The process of measuring quantities of materials from drawings and specifications prepared by architects, engineers, and other designers is known as quantity takeoff. For more information, see To Calculate Volumes for Overlapping Materials or Overhangs.Understanding Quantity Takeoff (QTO) Concepts and Tools
Optionally, repeat Steps 7 through 13 to create all required materials and surfaces. For each data type added to a material, click the Condition field. In the Select Shape list, enter the shape name or select a shape. Select Corridor Shapes from the Data Type list. If you selected a quantity type of Structures, to add corridor shapes, select the new material. In the Select Surface list, enter the surface name or select a surface. If you selected a quantity type of Cut, Fill, Cut and Refill, or Earthworks to add surfaces, select the new material. Optionally, edit the cut, fill, and refill factors by selecting the corresponding fields. For more information about using Shape Styles to review material calculations graphically, see To Review Sectional Volume Results Graphically. Select the default style used to display the material section in a section view. Select the quantity type, either Cut, Fill, Cut and Refill, Earthworks, or Structures. To define or edit the criterion, click the Material List tab. To edit the description of the criterion, enter a new description in the Description field. To edit the name of the criterion, enter a new name in the Name field. In the Quantity Takeoff Criteria dialog box, click the Information tab. Right-click the Quantity Takeoff Criteria collection. In Toolspace, on the Settings tab, expand the Quantity Takeoff collection. 
Tutorial: Quantity Takeoff from Corridor Models You use the material list to generate quantity takeoff tables and reports. To create a new quantity takeoff criteriaĬreate quantity takeoff criteria as the first step in analyzing sectional material volumes.Īfter you create a quantity takeoff criteria, you can apply it to a sample line group to create a material list.
