How is cut and fill calculated?

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.

What is cut and 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.

What is cut and fill for earthwork?

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 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 fill volume?

Rectangular Area

1. Measure the length, width and depth of the area you want to fill with dirt.
2. Calculate the volume of dirt needed to fill the area you measured by multiplying length (120 inches) by width (60 inches) by depth (30 inches).
3. Convert cubic inches to cubic yards by dividing by 46,656 cubic inches.

What is the slope of a cut and fill called?

Side slope (Figure 5-2) is defined as the slope of the cut or fill expressed as the ratio of horizontal distance to vertical distance.

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.

How do I use cut and fill in Civil 3D?

Solution:

1. In command line type “COMPUTEMATERIALS”.
2. Select the alignment and sample line group to sample, then click “OK”.
3. Change “Quantity takeoff criteria” to “Cut and Fill” or other desired criteria.
4. Map the sampled surfaces to the correct object names, then click “OK”.

What is cut fill analysis?

The Cut Fill tool summarizes the areas and volumes of change from a cut-and-fill operation. By taking surfaces of a given location at two different time periods, it identifies regions of surface material removal, surface material addition, and areas where the surface has not changed.

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.

What is a cut slope?

Cut/Slope means any slope greater than 60\% or man-made contour that exposes the vertical soil profile. Cuts and slopes require a 5 foot horizontal setback for every 1 foot of vertical height to any dispersal system.

How do you calculate cut volume from fill depth?

In either case, the volume is calculated by multiplying the cut of fill depth by the area of the grid cell. Once the volume has been calculated for each grid cell, all of the cut cells are added together to obtain the total cut volume.

How do I calculate the cut and fill for my project?

For each node of the grid, determine the existing and proposed ground level and calculate the cut or fill required. 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 do you determine the areas of cut and fill?

There are several different methods used to determine the areas of cut and fill once the sections have been plotted. Perhaps the simplest (but most time consuming) method is to plot the sections on gridded paper and count the grid cells of the cut and fill areas.

How do you calculate cut and fill in Revit?

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.
