What Is a Bank Cubic Yard? A bank cubic yard, or BCY, is the calculation or measurement of 1 cubic yard of earth or rock in its natural state before it is removed from the ground. The volume measurement is commonly used in the mining and construction fields.


How do I convert bank cubic yards to loose cubic yards? ... the estimator should remember the differences in volume between in-bank soil, loose soil that has been excavated, and fill soil that has been compacted. ... 100 bank cubic yards in the ground can become 125 cubic yards loose in the trucks hauling soil from the excavation area.


How do you covert from bank cubic yard to running or loose yard? ... One Bank Cubic Yard (BCY) equals 27 cubic feet (3'x3'x3') of earth in situ. When excavated and loaded loosely into a truck, the ...


This would convert the 1.0 Bank Cubic Yard (BCY) to 1.25 Loose Cubic Yards (LCY). According to the estimate of the job, you now know you will actually need to haul this 1.25 LCY to another location on the job site to use as compacted fill material. This means that the Loose Cubic Yards will become Compacted Cubic Yards (CCY).


Job Efficiency Factors for Earthmoving Operations Units of Measure Cubic Yard (bank, loose, or compacted) Volume Bank: VB Bank cubic yards (BCY) Density B Lb /BCY Loose: Vl Loose cubic yards (LCY) Density L Lb/LCY Compacted: Vc Compacted cubic yards (CCY) Density C LB/CCY Swell: A soil increase in volume when it is excavated.


The bank cubic yard is "as is" in the ground. When you dig it up, the volume will increase, so there would be more losse cubic yards. Assuming the numbers are reversed by the 1.15 factor is right, it would be 1.725 tons per banked cubic yard.


One Bank Cubic Yard (BCY) equals 27 cubic feet (3'x3'x3') of earth in situ. When excavated and loaded loosely into a truck, the original one BCY of.


Compacted cubic yard CCY Bank vs Loose vs Compacted Job Efficiency Factors for from EGR 471 at Michigan State University


I might be over thinking this simple concept, but I would like for it to be automatic come test time. Below are the equations that I have come up with for BCY, LCY, and CCY while working example problems


The loose density is irrelevant because you're not asked about how the material will be reused. You're given the max capacity of the truck (27000 lbs) and you need to relate that to the bank material only. Your steps are correct, but think of it as a weight transfer problem rather than a density (bank vs loose) issue.
