Frequent question: How do you calculate cubic yards of excavation?

How to calculate cubic yards? The formula: Number of Cubic Yards = Length (in feet) Width (in feet) Depth (in feet) ÷ 27. Simply multiply the three dimensions together to find the number of cubic feet, then divide by 27 to find the number of cubic yards.

How do you calculate excavation volume?

Many would calculate the volume as the average width * the average length * the depth, or 10*10*5 = 500 cf, or 18.5 cy.

How do you calculate earthwork volume?

The pay item unit of measurement for volume usually is the cubic yard. Keep this relationship in mind: One cubic foot = 1728 cubic inches; One cubic yard = 27 cubic feet; and One cubic foot = 7.48 gallons. Volumes of earthwork usually are computed from cross sections taken before and after construction.

How do you calculate earthwork in excavation?

In this method Sections are drawn for Each Line of Value. Area of Cutting and Filling is found out for each Section with Trapezoidal Method or Nett Area Calculation Method. Then volume is determined by multiplying Average Area with Distance between Sections.

How do you calculate excavation depth?

How to Determine Depth of Foundation?

  1. Load applied from structure to the foundation.
  2. Bearing capacity of soil.
  3. Depth of water level below the ground surface.
  4. Types of soil and depth of layers in case of layered soil.
  5. Depth of adjacent foundation.


What is Bank volume?

Bank volumes are measurements of soil quantities already in the ground. … Loose volumes are the volumes of soil that haven’t been disturbed during excavation and removal and are placed in the back of dump trucks or in stockpiles in a loose condition.

How do I find volume?

The volume formula depends on the shape of the object. One of the most popular shapes is a rectangular prism, also known as a box, where you can simply multiply length times width times height to find its volume.

What method are we using to calculate volume?

The formula for the volume of a rectangular solid is Volume = length * width * height, or V = lwh.

What is midsection formula?

A. The mean depth is the average of depths of two consecutive sections. The area of mid-sections is calculated by using mean depth. The volume of the earth work is calculated by multiplying the mid-section area by the distance between the two original sections.

What is earthwork method?

Earthworks – created through the moving and/or processing of massive quantities of soil or unformed rock. Cutting – The process of excavating earth material from a work location to achieve the desired topography.

What is the difference between earthwork and excavation?

 This earth work may be either earth excavation or earth filling or Some times both will get according to the desired shape and level. …  Basically the volume of earthwork is computed from length, breadth, and depth of excavation or filling.

What is the rate of earthwork excavation?

Example of Rate Analysis of Excavation in Earthwork

Sr No. Description Rate
1 Backhoe Excavator ( Per Day Excator 200 Cu.m.) 7000.00
2 Tractor/Dumper 2000.00
B Labour for Dressing
1 Mason For Leveling 700.00

How do you calculate cost of excavation?

of days required for 10m3 excavation = 10/242.4242 = 0.04125 days. Likewise, based on the capacity of other equipment, labors etc., their cost is calculated. Contractors profit is also added to the total cost of labors and machineries. Then grand total gives the rate of excavation per 10m3 of soil excavation.

What is the formula of depth?

Answer: Use the following formula for measuring ocean depth. D = V Times 1/2 T D = Depth (in meters) T= Time (in seconds) V = 1507 m/s (speed of sound in water) Calculate the depth foe each of the times given below, using the formula above.

What are the three methods of excavation?

  • 3.2 Trench excavation.
  • 3.3 Basement excavation.
  • 3.4 Road excavation.
  • 3.5 Bridge excavation.
  • 3.6 Dredging.

What is the minimum depth of footing?

The minimum depth of footing in sloping ground with the rock, the horizontal distance shall be at least 600 mm or 2 feet from the lower edge of the footing. In case of sloping ground with normal soil, the horizontal distance shall be 900 mm or 3 feet from the lower edge of footing.
