Calculate cut/fill and material volumes needed for a roadway, usually for the purpose of bidding on a construction job. Create both the original ground surface and the corridor surface, specifying materials for each course in the corridor, and running a report to determine the volumes of cut and fill needed along the corridor.

Following are the basic steps for this workflow. For more detailed instructions, see Perform Corridor Takeoff.

Steps:

Commands:

1.

Work through the flow for creating an original ground surface.

See Workflow: Create and Edit a Surface.

2.

Work through the flow for creating an alignment-based corridor.

See Workflow: Create a Corridor.

3.

Digitize additional data, such as topographic contours, and other missing linework.

Do this step if you routinely digitize new data in your projects. The commands for digitizing specific types of lines are optimized for digitizer input; you can enter data for each new line from the digitizer puck without returning to the on-screen command pane. These features enable you to quickly and simply digitize multiple objects in series.

4.

Run a report to determine the volumes of cut and fill materials needed along specific portions of the corridor.

The report multiplies the average of cut and fill areas at two cross-sections by the distance between their stations.

5.

If desired, work through the flow for performing a corridor mass haul analysis along the corridor.
