To view earthwork quantities

View cut and fill volumes for an entire component road, a specified station range, or multiple, selected roads.

After you make changes to a component road, InfraWorks updates the associated cut and fill quantities. When editing the road, you can quickly compare cut and fill volumes between edits to get closer to balancing the earthworks toward a net 0 volume. You can also export the cut and fill data to a standard CSV file and import the data to a spreadsheet application for additional reporting and analysis.

Set a Station Range

When performing earthwork or material quantity analysis on a road, you can independently set a station range limiting the length of road to be analyzed for each of the two analyses. As a result, each analysis may return quantities for different segments of the same road, if different station ranges were specified in the two analyses.

Get Total Earthwork Cut and Fill Values for Multiple Roads

InfraWorks calculates cut and fill values for multiple, selected roads. If two or more roads share intersections (and, you have turned on the Include Intersections & Roundabout setting), then the total value adds the cut and fill values for the shared intersection or roundabout. It adds the values one time only.

Include or Exclude Earthwork for Bridges or Intersections and Roundabouts

Using Earthwork Quantities tool settings, you can also choose to include or exclude earthwork quantities for bridges or intersections and roundabouts.

To Customize Calculations Using Earthwork Quantities Settings

Click (Specify settings) to display the Earthwork Settings panel. You can specify the following: * Station Increment: Specify the distance between stations for earthwork calculations. * Sample at Key Station: Toggle on to include values at key stations in earthwork calculations. Key stations include superelevation stations (for example, normal shoulder, normal, crown, level crown, and so on) and stations where road component transitions start and end. * Include Intersection & Roundabout: Toggle on to include the cut and fill volumes for intersections or roundabouts in the selected road. * Include Bridge: Toggle on to include the cut and fill volumes for bridges connected to the selected road. Note: Earthwork quantities for bridges are calculated from pier foundations (foundation caps) and the conical slope (the area where the bridge and road end connect). The conical slope is included in earthwork calculations when the road grading method is set to Fixed Width.

To Calculate Earthwork Quantities

1. Optional: Adjust Earthwork Quantities Settings, as needed. For example: On the Earthwork Quantities panel, turn on the Station Range option and specify Start and End Station values to limit the calculations to a specific area of the road.
2. Optional: Reset current Unit Configuration and unit type and precision for volume data: Click Unit Configuration in the Application Options dialog.
3. In the model, select a component road or select multiple component roads. The Cut and Fill icon displays in the Analysis Hub below the Stack.
4. Click the Cut and Fill icon to display more tools, and click to calculate the cut and fill values for the selected road or roads. Note: When you edit the road, the quantity values are not updated automatically. After editing a road, click to recalculate the quantities.

5. Click (View detail values) to see cut, fill, and net volumes in the Earthwork Quantities panel. Note: From the right-click menu, select Show Cross Section View. Switch to the Cut/Fill Areas view in the Cross-Section Viewer to display cut and fill area values and a diagram of the relevant critical stations. (Cut and fill area values are not calculated for intersections, roundabouts, or bridges.)

6. To save the earthwork data to a CSV file, click (Generate report), navigate to the folder where you want to save the file, and click Save.

Methods Used for Earthwork Calculations

Roads: The Average End Area method is used to calculate cut and fill volumes. This method calculates the volume between two cross sections; the cross-sectional areas are averaged and multiplied by the distance between cross sections to determine the volume.

Intersections and roundabouts: The Surface Comparison method is used to calculate cut and fill volumes. This method compares the cut and fill volumes between the existing ground and the surface of the bounding box for the intersection or roundabout.
