Use this tab to define the quantity takeoff criteria.
- Add New Material
-
Adds a new empty material to the list. After you add the material, you can edit its type and settings and use the Define Material fields to populate it with components that define the criteria for calculating volumes.
-
-
Opens the Name Template dialog box, where you can modify the material naming template.
- Add A Subcriteria
-
Adds a subcriteria to an empty material or to a material with existing subcriteria. For more information, see About Calculating Volumes for Overlapping Materials or Overhangs.
-
-
Deletes the material or data component that is currently selected in the Material Name column.
Define Material
- Data Type
-
Specifies the type of data that is compared and processed when defining the material. Either Surface or Corridor Shape.
- Select Surface/Shape
-
Lists sampled surfaces and corridor shapes for this sample line group. Select a surface or corridor shape. Surface and corridor shape names in the material criteria are mapped to actual surfaces and shapes when you generate the quantity takeoff report.
Note: Corridor shapes can be added only to a material with a Structure quantity type. -
-
Adds the data specified in the Define Material fields to the selected material name.
Note: If a material is not selected, the data is not added.
The properties table contains the following columns:
- Material Name
-
Specifies the material name. Click
next to the material name to display its components (surfaces). - Condition
-
Specifies the condition on which to base the calculation:
- Above. Specifies that an area above this surface is included in the material definition. Used with Below to define two or more surfaces for cut, fill, and structures material types.
- Below. Specifies that an area below this surface is included in the material definition. Used with Above to define two or more surfaces for cut, fill, and structures material types.
- Base. Specifies that this surface is the surface to compare against the compare surface. Used with Compare to define two or more surfaces for earthworks or cut and fill material types.
- Compare. Specifies that this surface is the surface to compare against the base surface. Used with Base to define two or more surfaces for earthworks or cut and fill material types.
- Include. Specifies a corridor shape that is included in the structure type definition.
- Quantity Type
-
Specifies the quantity type:
- Cut. Calculates the material to remove.
- Fill. Calculates the material to add.
- Cut and Refill. Defines an area in the section where a material is removed and refilled with fill material.
- Earthworks. Compares two surfaces to calculate both cut and fill areas and displays them separately.
- Structures. Calculates the volume of one or more corridor shapes (as defined by the shape codes that are used to define the corridor). For information about shape codes, see About Point, Link, and Shape Codes for Subassemblies.
- Shape Style
-
Specifies the default style used to display the material in a section view.
- Cut Factor
-
Specifies the expansion or swell of the cut material.
- Fill Factor
-
Specifies a factor to accommodate for the contraction or shrinkage of the fill material.
Note: For example, for a material that compacts to 93% of its original value when used as fill, enter 1.075 (which is derived by dividing 1.0 by .93) as the fill factor to compensate for the extra material that must be added. - Refill Factor
-
Specifies usability factor used to calculate how much cut material can be reused as fill.
- Define From A Sample Line Group
-
Specifies that criteria is defined from sections in a sample line group. Opens the Define Material Criteria dialog box.
