How do you calculate earthwork?

Asked By

111

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.

Thus, How do you calculate fill? Calculate the amount of fill needed with this formula: Width x Length x Depth divided by 27. All these dimensions should be calculated in feet. For example, to find the volume of an area 25-feet wide by 36-feet long with a depth of 3-inches, enter 25 x 36 x .

Additionally Which formula is used to accurate estimate of earthwork? Following methods are used in the calculation of earthwork: Prismoidal method. Trapezoidal method. Midsection area method. mean section area method.

How do you calculate volume of earthwork? Volume = Sum * 100 (Area of Each block) = 4.6225 * 100 = 462.25 (Filling).

How is area of embankment calculated? To find:

We have to calculate the total volume of earthwork in embankment by using the mean area method.
Procedure:
Before proceeding further, Go through the article
. How to calculate the sectional area of an embankment?
Volume V15:
A1 = [ bd1 + d1²S]
A1 = 10.005m².
A2 = 12.58m².

How much fill Do I need calculator?

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 cut and fill in earthwork?

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 the volume of a ditch?

Find the volume of your ditch by multiplying the length times the width times the height. Your answer will be measured in cubic yards. If your ditch turns or curves, break it down into rectangular cross sections to find the volume of each rectangle separately. Then, add the volumes together to find your total volume.

How do you calculate the depth?

Worked Example

Step 1: List the known quantities. Wave speed, v = 1500 m/s. …
Step 2: Write out the wave speed, distance and time formula.
Step 3: Rearrange the equation to make distance (x) the subject. x = v × t.
Step 4: Put known values into the equation. x = 1500 × 0.12 = 180 m.
Step 5: Half the distance to obtain the depth.

How do you calculate rate per m3 for excavation?

So, 10 cu.m. work for = 0.050 Days required. As per Backhoe Excavator =Tractor/Dumper.
The cost of a Backhoe excavator machine for 10 m ³ = 0.050 Day x 7000 Rs. ( This took in CPWD)
As per the same calculation for Tractor/Dumper = 0.050 Day x 2000 Rs. ( This took in CPWD)

How do you find depth with area?

Mean Depth is equal to the cross-sectional area divided by the surface width.

How do you find depth with height and width?

How do you calculate depth from diameter?

Calculating total depth of a round diamond: The formula for calculating the total depth of a round brilliant cut diamond is actually pretty simple. Simply divide the depth of the diamond, by the average diameter. In this case, the depth of the diamond is 4.00 and the average diameter is 6.505.

How do you calculate cubic meters?

The formula of cubic meter for measuring different units

Meter = l × b × h = cubic meters.
Centimetre = l × b × h ÷ 10,00,000 = cubic meters.
Millimetre = l × b × h ÷ 1,00,00,00,000 = cubic meters.
Inches = l × b × h ÷ 61,023.8 = cubic meters.
Feet = l × b × h ÷ 35.315 = cubic meters.

How is digging area calculated?

How do you calculate trench excavation? Determine the volume of the trench by using the formula: Volume = Width x Length x Depth. As an example, a trench 12 feet long with an average width of 2.3 feet and an average depth of 5 feet has a volume of (12 x 2.3 x 5) cubic feet.

How is earthwork rate calculated?

Rate Analysis of Manual Earthwork Excavation

The concept can be explained with a simple example. …
Let the final dimension of the pit be: …
Volume of excavation (Vp) = Length x Breadth x Height. …
Number of Mate = 0.06V = 0.06 x8= 0.48 nos.
Number of Mazdoor = 0.62V=0.62 x 8 = 4.96 nos.
The cost of Mate = No.

How do you calculate excavation work?

The cost of excavation is generally estimated by multiplying the total excavation volume to the excavation price per unit. For ex : Let us assume that you want to excavate a pit of size : 2 x 2 x 2 meter. The market price for excavation is 10$/cu.

How do you find the area of a trench?

Multiply the length times the width to obtain the area of the trench in square inches. Performing this step leads to 345 inches times 16 inches, or an area of 5,520 square inches. Divide the trench area by 144 to convert to square feet, because one square foot equals 144 square inches.

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.

How do you calculate backfill and excavation?

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.
