Finally, the Cum. Net Volume value at each station is calculated as the
cumulative Reusable volume minus the cumulative Fill volume.

Tutorial: Working with Mass Haul Diagrams
This tutorial demonstrates how to create and edit mass haul diagrams to display
earthworks in profile.
Mass haul is defined as the volume of material multiplied by the distance it
is moved during construction. A mass haul diagram consists of two objects:
a mass haul line, and a mass haul view. The mass haul line represents the free
haul and overhaul volumes in cut and fill conditions along an alignment. The
mass haul view is the grid on which the mass haul line is drawn.
The middle axis of the mass haul view is known as the balance line. The
location of the mass haul line relative to the balance line indicates material
movement in the current design. When the mass haul line rises above the
balance line, it indicates a region in which material is cut. When the mass
haul line falls below the balance line, it indicates a region in which material
is fill.
There are two methods to compare free haul volume and overhaul volume:
Grade Points
Grade points are stations at which the proposed project design transitions
from cut to fill. In a mass haul diagram, a grade point is the highest or lowest
point in a mass haul region. A grade point is the highest point in a mass haul
region where the profile transitions from a cut condition to a fill condition.
A grade point is the lowest point in a mass haul region where the profile
transitions from a fill condition to a cut condition.
In the grade points method of measuring free haul, a horizontal line that is
the length of the specified free haul distance is drawn. The line is positioned
so that it is both parallel to the balance line and touches the mass haul line.
The volume that is enclosed in the area formed by this line and the mass haul
line is free haul.
In the following image, the green areas are free haul volume, and the red areas
are overhaul volume. The magenta circles and arrows indicate the grade points
on the mass haul line and profile. The vertical magenta lines illustrate the
