What is bank soil and loose soil?
• Soil Conditions – Bank: Material in its natural state before. disturbance (in place) • Unit volume is Bank Cubic Meter (BCM) – Loose: Material that has been excavated or. loaded.
What is a bank cubic yard?
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. Native soils have been compacted over long time spans, so these soils are usually pretty dense.
How do you convert bank cubic yards to loose cubic yards?
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 do you calculate bank 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 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.
What does loose cubic yard mean?
loose cubic yard (or meter) A unit to express the volume of loose material.
How do you calculate loose cubic yards?
For example, the 1.25 LCY we calculated in the previous example might need to be compacted by 10\% when filled into the ground to convert the unit to Compacted Cubic Yards. To calculate this, you would multiply 1.25 LCY by 1.1, which equals 1.38 Loose Cubic Yards to equal one Compacted Cubic Yard.
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.
What is a loose cubic yard (LCY)?
In comparison, a loose cubic yard, or LCY, is the measurement of the soil after excavation. When soil is removed from the ground, it is no longer compact, and it further swells with the addition of air.
What is a compacted cubic yard (CCY)?
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).
How much does a cubic yard of soil swell out of ground?
In this case a cubic yard out of the ground swells or fluffs by 15\%. Then you loaded it all back into dump trucks and placed it back in the same hole at 90\% optimal compaction (which is a realistic specification for soil in turf areas). But wait, it didn’t all go back into the hole.
