Balance cut material volumes
NOTE This exercise uses Mass Haul-1.dwg with the modifications you made in
the previous exercise, or you can open Mass Haul-2.dwg from the
folder (page 819).
1 Zoom in on the mass haul region that is on the left-hand side of the
diagram.
Notice that the highest point of the green free haul area is at station 3+25.
This is the grade point, which is the point at which free haul transitions
from cut to fill. Depending on the site conditions, grade points can be
logical locations for dump sites or borrow pits, which can reduce or
eliminate overhaul.
2 At station 3+25, hover the cursor over the mass haul line.
Notice that the tooltip displays the current station number (3+25) and
volume (approximately 1500.00 Cu. Yd.).
3 Select the mass haul line. Right-click. Click Mass Haul Line Properties.
4 In the Mass Haul Line Properties dialog box, click the Balancing Options
tab.
5 In the Add/Remove Borrow Pits And Dump Sites area, click Add Dump
Site.
6 In the Station cell, enter 325.
This is the number of the station at the grade point for the volume above
the balance line.
7 In the Capacity cell, enter 1500.
This is the approximate volume (1500.00 Cu.Yd.) at the grade point.
8 Click OK.
