How do you do cut and fill calculations by hand?
This method involves drawing horizontal and vertical lines over your site plan to divide it into grid cells of equal size. You then include the existing elevation and proposed elevation for each corner of the grid cells, and work out the difference between the two, as this will be cut or fill depth for that spot.
How do you calculate a filling?
Area of the plot = Length x Width = 40 x 30 =1200 sft. Suppose we need to fill the plot by 3’5” = 3.41 feet. ∴ Depth of the plot = 3.41 feet. Volume of plot to be filled = 1200 x 3.41 = 4092 cft.
What is cut and fill in road construction?
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.
How do you calculate cut and fill quantities?
For each section line the cut area and the fill area is determined. The volume between two sections is determined as the average area of the two sections multiplied by the distance between them. By adding together the volumes between all of the sections the total cut and fill volumes are obtained.
How do you calculate sand fill?
To determine how much sand, topsoil or stone you need to fill an area:
- Measure number of square feet in the area.
- # of square feet x depth in feet = # of cubic feet.
- # of cubic feet /divided by 27 = # of cubic yards.
- # of cubic yards x (unit weight in pounds / 2000) = # of tons needed.
How do you calculate soil quantity in road construction?
- or compacted soil = 1.3 × loose soil.
- = 1.3 × 13.74 = 17.862 cu.
- = 17.862 × 35.315 = 630.80 cubic ft.
- Note: Compacted volume of the soil varies from 1.25 to 1.35 times the loose soil, depending upon the texture and the grain size.
- = 17.862/5 = 3.57 nos.
- = 17.862/2 = 8.931 nos.
- = 6.31÷1.75 = 3.60 nos.
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.
