What is a mass diagram?

What is a mass diagram?

Mass Diagram- A graphical representation of the cumulative amount of earthwork moved along the centerline and distances over which the earth and materials are to be transported.

How do you make a mass haul diagram?

To Create Mass Haul Diagrams

1. Select a material list.
2. Select a material to display as mass haul line (Total Volume, Total Cut Volume, Total Fill Volume, Total Unusable Volume, and any other material associated with the material list).
3. Specify a mass haul line style.

Why do we need to know the mass diagram?

Mass diagrams indicate the spatial relationship between excavation (cut) and embankment (fill) on a project and are good tools in planning for efficient earthwork operations. The basic excavation and embankment volumes and locations must be known before the mass diagram can be constructed.

What is haul survey?

Haul = volume of earthwork * distance moved.

What is the use of mass haul diagram?

Use mass haul diagrams to display earthwork volumes along an alignment, based on sectional volume computation. A mass haul diagram presents a graphical view of material moved in the proposed design site, displaying balance points, free haul and overhaul regions, and grade points.

What is free haul in construction?

The free-haul limit is the specified distance the excavated material is hauled without additional. compensation.

What does lead and lift mean?

The horizontal distance through which the excavated earth from a borrow pit is carried to the place of the embankment is known as lead. The vertical height through which the excavated earth from a borrow pit is to be lifted is known as lead. Read Also: Turfing.

What is meant by free haul?

The distance every cubic yard is entitled to be moved without an additional charge for haul.

What is meant by haul distance?

The distance measured along the center line or most direct practical route between the center of the mass of excavation and the center of mass of the fill as finally placed. It is the distance material is moved.

How do you calculate haul volume?

*mile).

1. – Haul = volume of earthwork * distance moved.
2. – Limit of Economic Haul (L.E.H.) =
3. Freehaul Distance (F.H.D.) + Economic Overhaul Distance(Limit) (O.H.D.)
4. – Economic Overhaul Distance = Cost of Borrow / Cost of Overhaul.

How a mass haul diagram is used to calculate the earthwork quantities?

Mass diagrams (or mass-haul diagrams) are plots of the cumulative volumes of cut and fill along an alignment. The most economical way to handle the distribution of earthwork volumes can be determined from the diagram. The rising curve on the mass diagram indicates excavation and a descending curve indicates embankment.

What is haul construction?

Haul: A haul refers to the transportation of your project’s excavated materials. The haul includes the movement of material from the position where you excavated it to the disposal area or a specified location.

What does the average haul mean in a mass diagram?

The average haul is a specific area in a mass diagram. It represents how many cubic yard stations are between balance points divided by the ordinate of mass that the yardage gets hauled. These diagrams are crafted using a mass haul view and a mass haul line.

Where are balance points on a mass haul diagram?

These balance points can be found on the diagram’s balance line. More specifically, the balance points are stations where the net volume equals zero on the line. To measure free haul with balance points, begin by duplicating the mass haul line and move horizontally. The distance it moves will be based on the free haul distance.

What do you mean by mass haul line?

The mass haul view refers to the grid where the mass haul line is placed. The mass haul line refers to the overhaul and free haul volumes in fill and cut conditions that run along an alignment. A project is in a cut region if the mass haul line rises.

Which is the middle axis of the 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.
