Represent free haul and overhaul volumes using grade point and balance point methods.
During project development, contractors and design engineers may try to balance the mass haul requirements by considering free haul distances, any overhaul , and the use of borrow pit s for embankments and dump site s for extra excavated volumes, based on the economic haul limits and the site conditions.
In AutoCAD Civil 3D, you can specify the free haul distance as required. You can also specify the location of borrow pits and dump sites along the roadway, with assumed capacity of the borrow pits or dump sites.
There are two ways of representing free haul (and any overhaul) in mass haul diagrams in AutoCAD Civil 3D:
- measured from grade point s
- measured from balance point s
Topics in this section
- Measure from Grade Points
Represent free haul and overhaul from grade points along the mass haul line.
- Measure from Balance Points
Represent free haul and overhaul from balance points, where the mass haul line and balance line meet.
