Published Mar 30, 2026

Bank Cubic Yards (BCY) can be converted to Loose Cubic Yards (LCY) by applying a Load Factor (L.F.) to the LCY depending on the type of material being exported. … The formula for conversion is:BCY = LCY x (L.F.); Conversely LCY = BCY ÷ (L.F.)Example (Sand, dry, loose):LCY = 1,000 BCY ÷ 0.89 = 1,124 LCY.

How is swell factor calculated?

Calculating the percentage change in height from the wet soil to the dry will give you a measure of the swell factor of the soil. For example, if the dry soil was 1 inch high and the wet soil is 1.54 inches high, divide 1 by 1.54 and multiply by 100 to get a 65 percent swell factor.

How do you convert CCY to Lcy?

  1. How many 10cy truck loads of soil = 1000CCY ?
  2. Swell = 30%
  3. Shrinkage = 25%
  4. BCY = CCY/(1-shrinkage)
  5. LCY = BCY*(1+Swell)
  6. LCY = CCY/(1-shrinkage)*(1+swell)
  7. LCY = 1000/(0.75)*1.30 = 1735 LCY.
  8. Truck loads = LCY/10 = 174 truck loads.

What does Lcy mean in construction?

When preparing bids or construction cost-estimates, knowing the loose cubic yard (LCY) or bank cubic yard (BCY) quantities required for fill construction is important.

How much is a loose cubic yard?

A cubic yard is the volume of a cube with the length, width and height of one yard (3 feet or 36 inches). One cubic yard is equal to 27 cubic feet. To help you picture this, the volume of two washing machines is just over a cubic yard.

How do you calculate shrink and swell?

List of swell and shrink percentages at bottom of page. Shrinkage = volume after compaction/volume before excavation. Both the loose and compacted volume are calculated from the bank volume. Example: If you are excavating dry clay it is listed as having a swell of 50% and a shrinkage of -10%.

How do you calculate soil bulking factor?

To use a bulking factor number you have to multiply the bulking factor number by the excavated volume size. If your excavation was 15 m3. You must consider the bulking factor of the material you are digging to ensure you correctly plan for the removal costs and time to do it in.

What is Lcy and BCY?

BCY = bank cubic yards. LCY = loose cubic yards. CCY = compacted cubic yards.

How do you convert LCY to CY?

To determine the volume of dirt you will have to haul to another location on the site or off the site, you would multiply the cubic yard by a Swell Factor, which in this case would be 1.25. This would convert the 1.0 Bank Cubic Yard (BCY) to 1.25 Loose Cubic Yards (LCY).

How is BCY calculated?
  1. Bank Cubic Yards (BCY) can be converted to Loose Cubic Yards (LCY) by applying a Load Factor (L.F.) to the LCY depending on the type of material being exported. …
  2. The formula for conversion is:
  3. BCY = LCY x (L.F.); Conversely LCY = BCY ÷ (L.F.)
  4. Example (Sand, dry, loose):
  5. LCY = 1,000 BCY ÷ 0.89 = 1,124 LCY.

How do you calculate embankment cubic yards?

  1. Calculate your area.
  2. Calculate your volume: Multiply area times the depth to get volume in cubic feet.
  3. Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer.
  4. Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard.

How many SF are in a cubic yard?

How do I work out how many tons of soil I need?

Loose Topsoil As a general rule, a tonne of a standard topsoil equals approximately 0.67m3. Divide the cubic metres required by 0.67 to give you the tonnage.

What is a soil bulking rate?

The bulking factor is the ratio or percentage of the volume change of excavated material to the volume of the original in situ volume before excavation. The bulking factor is used to estimate the likely excavated volumes that will need to be stored on site or perhaps removed from site.

How do you calculate bulk excavation?

So, the formula is: Ab = Wb * Lb, where Wb and Lb are the width and length of the bottom of the excavation. At = Wt * Lt, where Wt and Lt are the width and length of the top of the excavation. In our example, Wb = Lb = 5 and Wt = Lt = 15, so Ab = 5 * 5 = 25 and At = 15 * 15 = 225, and D = 5.

How do you calculate shrinkage factor?

Subtract the final size from the original size to find the amount of the shrinkage. For example, if a felt square shrinks from 8 square inches to 6 square inches, subtract 6 from 8, resulting in 2 square inches of shrinkage. Divide the amount of shrinkage by the original size to find the shrinkage rate.

What is swelling and shrinkage?

Shrinking and swelling soils Shrink–swell is the volume change that occurs as a result of changes in the moisture content of clay-rich soils. Swelling pressures can cause heave, or lifting of structures, whilst shrinkage can cause settlement or subsidence, which may be differential.

What is shrinkage retail?

Shrinkage is the loss of inventory that can be attributed to factors such as employee theft, shoplifting, administrative error, vendor fraud, damage, and cashier error. … This concept is a key problem for retailers, as it results in the loss of inventory, which ultimately means loss of profits.

What is a BCY?

Construction Knowledge Series: What is a Bank Cubic Yard (BCY) vs. … A cubic yard is volumetric measurement of something that is 3′ x 3′ x 3′ = 27 cubic feet. A cubic yard of native soil in place would be called a bank cubic yard.

What is swell factor in excavation?

The swell factor of soil is the amount of volume increase from the undisturbed (BCY) to the excavated (LCY) state due to the air pockets (fluff) created.

How do you calculate compacted cubic yards?

Multiply the three dimensions together to find the number of cubic feet (0.5 feet x 12 feet x 12 = 72 cubic feet) Divide the cubic feet by the number of cubic feet in a cubic yard (27) to find the number of cubic yards (72 ÷ 27 = 2.67 cubic yards).

What airport is Lcy?

How do you calculate soil compaction?

3.7 Calculate percent relative compaction by dividing the dry density of the material from the test site by that material’s moisture density relation curve’s maximum dry density, and multiply by 100%.

How do I calculate how much soil I need to remove?

Calculate the volume by multiplying the measured length and width of the space together, then multiply the result by the height of the room. A 7-foot ceiling gives the room 300 * 7 feet or 2,100 cubic feet. Divide the area by 27 to find the volume of the dirt in cubic yards (because 1 cubic yard = 27 cubic feet).

How do you measure soil compaction?

Divide the weight of the dry soil by the volume of sand required to fill the hole to find the soil density in pounds per cubic foot. For example, if the weight of the soil is now 1 lb. and the volume of the sand in the hole is . 5 cubic feet, the density would be 1 lb/.

How many yards of concrete do I need for a 24x24 slab?
