How do you calculate earthwork in a filling?

Volume = Sum * 100 (Area of Each block) = 4.6225 * 100 = 462.25 (Filling).

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 calculate cut and fill in Excel?

P = The average of the proposed elevation at the four corners of the cell. Then all the cells that have negative difference (cut) are added together to find the total cut volume and all the sells with a positive difference (fill) are added together to find the total fill volume.

What is cut and fill in earthworks?

In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.

What is cut and fill for earthwork?

How do you calculate earthwork?

The determination of earthwork quantities is based upon field cross- sections taken in a specified manner before and after excavation. Cross- sections are vertical profiles taken at right angles to the survey centerline. Every section is an area formed by the subgrade, the sideslopes, and the original ground surface.

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?

Backfill for Figure 3.1:

1. Backfill volume = excavation volume – footing volume – wall volume.
2. (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”)
3. Backfill volume = 207.4 cubic yards.
