2 Double-click the Earthworks style to open the Quantity Takeoff Criteria dialog box. 3 Click the Material List tab. This tab contains a pre-defined table for calculating earthworks (cut and fill) by comparing a Datum surface layer to an existing ground surface layer. 4 Expand the Earthworks item in the table. You will use the Earthworks criteria in the next exercise to calculate the quantity takeoff. Notice that the Condition for the EG surface is set to Base, while the condition of the Datum surface is set to Compare. This indicates that the material is going to be fill when Datum is above EG, and cut when Datum is below EG. Also note the three Factor values in the table: ■ The Cut factor is typically used as an expansion factor for excavated material. It is usually 1.0 or higher. ■ The Fill factor is typically used as a compaction factor for fill material. It is usually 1.0 or higher. ■ The Refill factor indicates what percentage of cut material can be reused as fill. It should be 1.0 or lower. 5 Click Cancel. To continue this tutorial, go to Exercise 2: Creating a Material List (page 591). Exercise 2: Creating a Material List In this exercise, you will create a material list, which defines the quantity takeoff criteria and surfaces to compare during an earthworks analysis. A material list is required to generate either an earthworks volume report or a mass haul diagram. A material list specifies the existing ground and datum surface to compare, and is saved with the sample line properties. For more information, see the AutoCAD Civil 3D Help topic Generating Material Lists. This exercise continues from Exercise 1: Reviewing Quantity Takeoff Criteria and Report Settings (page 590).
