Set up a network of haul roads with waste sites and borrow pits along a corridor construction site. Then run an analysis, review the mass haul diagram, and modify the mass haul calculations by adding barriers as well as material import and export locations. Recalculate to view the effects on the mass haul calculations. When you are satisfied that the earthwork is in balance, run the Corridor Mass Haul Report.

Following are the basic steps for this workflow. For more detailed instructions, see Create a Corridor Mass Haul Analysis and Create a Mass Haul Barrier.

Steps:

Commands:

1.

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

See Workflow: Create a Corridor.

2.

Run an initial analysis to determine the most efficient way to redistribute earthen material from cut zones to fill zones along a corridor construction job.

Create Corridor Mass Haul Analysis

3.

Define stations along an alignment beyond which earthen material cannot be moved.

Create Mass Haul Barrier

4.

Open a mass haul diagram of accumulated cut and fill volumes along a corridor's alignment to analyze the mass haul.

You must select a corridor before opening the diagram.
The view gives a complete picture of mass haul/earthworks with access to specific mass haul and volume/cost information and cost analysis.

Corridor Mass Haul Diagram

5.

Create haul roads to represent routes for vehicles performing mass haul operations.

Create Haul Road

6.

Select additional lines and convert them to haul roads.

Define a network of haul roads by connecting earthwork sites to a corridor using the haul roads.

Convert to Haul Road

7.

Geographically define borrow pits and waste sites.

Use borrow pits to provide additional fill for an alignment when there is a deficit in usable mass earthen material. Use waste sites to offload accumulated usable and unusable material.

Create Earthworks Site

8.

Recalculate the mass haul analysis and determine if the earthwork is balanced.

Refresh Mass Haul Analysis

9.

Force specified quantities of usable and unusable material to be accepted at one or more points along the alignment.

You can also specify costs and volumes which are considered in the corridor mass haul analysis.

Create Mass Haul Import

10.

Force the removal of specified quantities of material at one or more points along the alignment.

You can also specify costs and volumes which are considered in the corridor mass haul analysis.

Create Mass Haul Export

11.

Modify the network of haul roads to better manage the flow of the cut and fill volumes.

To change the shape of a haul road, right-click it and select Edit from the context menu. You can also edit its attributes in the Properties pane.

12.

Create a haul range to define the distance that each vehicle/machine can economically haul material.

Haul ranges are used when a mass haul analysis is balanced (see step 15).

Create Haul Range

13.

Refresh the mass haul analysis.

14.

Report on source and destination earthwork volumes for the mass haul analysis.

The Source section shows volumes of cut station interval along the alignment. The volumes are broken down into cut (for each material), import (usable and unusable) and borrow (implicitly usable).

The Destination section shows volumes of material used for fill at station intervals along the alignment. The volumes are broken down into fill (usable), export (implicitly usable) and dump (usable and unusable). The aggregate cost is also reported at each station interval.

15.

If desired, balance mass haul materials automatically or at specific grade points.

Define haul ranges before you balance mass haul materials.

Then you can run a report on the balance line.
