How do you manually calculate cut and fill?
The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell.
How do you calculate cut and fill quantities?
Once the cut or fill depth is calculated, multiply the value by the area of the grid cell. Do this for each square of the grid, then add the volumes together to determine the total cut and fill volumes for the project.
How does Autocad calculate cut and fill volume?
Okay in the next we will enter base surface. Okay go to this base surface or base surface is natural ground levels. And the next we will enter to comparison you compare surface ngl. And click on.
How do you calculate earthwork in a filling?
Every section is an area formed by the subgrade, the sideslopes, and the original ground surface. Volumes are computed from cross-section measurements by the average end area method. These formulas are used to compute earthwork quantities because the Specifications require this calculation.
How do you calculate fill volume?

How do you calculate the area of a filling?
Calculation Procedure of sand filling/soil filling for filling plot: Plot’s length (L) = 50 feet. Breadth/width of the plot (B) = 40 feet. Plot’s area (A) = Length x Width = 50 x 40 = 2000 ft2.

Which method is more accurate for calculation of earthwork?
The Section Method
The section method is the most complex and precise way to calculate an earthwork estimate. We use this technique when working on large-scale projects, such as dams, railway systems and roads.
How do you calculate backfilling quantity?
The volume of a rectangular cubed shape is found by the formula v = l x w x d, where v represents volume, l is the length of the trench, w is the width and d is the depth. Applying the numbers to this formula (8x 50x 6) the cubic footage of the example area is 2400 cubic feet.
What is cut fill ratio?
The cut/fill ratio is determined by the type of material being moved and what percentage of it will “settle” or “shrink” once compacted. Example: Setting the Cut/fill ratio at 1.2 means that you are moving at the rate of 1.2 cubic yards of cut to get 1.0 cubic yards of compact fill.
How do you find the volume of a cut?
How do you calculate filling materials?
For example, find the cubic footage volume of a backfill area that is 8 feet wide, 6 feet deep and 50 feet long. The volume of a rectangular cubed shape is found by the formula v = l x w x d, where v represents volume, l is the length of the trench, w is the width and d is the depth.
How do you calculate backfill?
Backfill for Figure 3.1:
- Backfill volume = excavation volume – footing volume – wall volume.
- (Note that only the portion of the wall that is in the trench is deducted, so the height of wall in the trench is the average trench depth minus 2′-0” for the footing: 6′-0” – 2′-0” is 4′-0”)
- Backfill volume = 207.4 cubic yards.
How do you calculate fill material?
Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 27 (the amount of cubic feet in a yard). The final figure will be the estimated amount of cubic yards required.
How do you calculate backfill material?
What is cut and fill factor in Civil 3D?
A typical ground can have a cut factor of 1.1 or 1.2, meaning that the material will have a 10% or 20% more volume after being excavated, compared to the volume measured in the model. This is helpful to plan and price properly for the transportation of material.
What is cut and fill factor?
The cut factor is used to adjust the volume of excavated material to account for the amount you expect the material to swell when it is excavated. The fill factor is used to account for the additional volume of material that would be required due to the compaction of the soil when it is placed.
What is the formula for calculating the depth of earthwork in cutting?
Example 2 (Both Cutting and Filling) :
| Summary of Various Methods | |
|---|---|
| Methods | Methods / Formula |
| Average Method | Volume=Depth of cutting/filling* area |
| Block Method | Volume=Sum of (Depth of cutting/filling* area of each block) |
| Section Method | Area to be found out using Trapezoidal Method Nett area Method Volume = Lx1/2(A1+ A2) |
How do you calculate land volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
How do you calculate backfill volume?
What is a cut volume and a fill volume?
The cut portion is the volume between the upper and lower surface when the upper surface is above the lower surface. The fill portion is the volume between the upper and lower surfaces when the upper surface is below the lower surface.
