Measurement of Structural excavation will be limited to excavation for foundation for bridges, retaining walls, box culverts or cross sectional area exceeding 1 sq. mtr, box culvert wing walls, head walls, toe walls and aprons, manholes, pump houses and sub-stations. For box culverts 1 sq. mtr or less, pipe culverts, storm sewers and ducts, measurement…
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. In comparison, a loose cubic yard, or LCY, is the measurement of the soil after excavation.
The cross sectional area of the box culverts will be that of the net opening of the culvert. For pipe culverts and box culverts of net opening are of 1 sq. mtr or less, no measurement will be made for excavation of abutments, wing walls, headwalls, toe walls and aprons etc, unless the excavation is declared 'in rock'.
This calculator will calculate the volume of excavated material using the length and width of the excavation in feet and the excavation depth from an average of four points. It will calculate the volume increase of the material using the swell/bulking percentage from Bank to Loose volume. A dump truck holds anywhere from 10 to 14 cubic yards of ...
In Situ, bank measure: soil as it is currently on-site. This is soil that has supposedly been at rest for a while. Even if it was compacted initially it has expanded gradually over to time to be at its current at-rest condition. Bulk Size, Swell, Transport Size, Loose, Expanded, Excavated: This is soil that has been excavated and is loose. This ...

- Width of the excavation, Depth of the cut, Material type, Working radius for digging and dumping, Required bucket dumping height. Excavator Trick of the Trade # 1: Step 1. Determine the bucket fill factor based on the material type - Using a chart or it will be given, Lacking any other information, use an average of 85 percent. Step 2.

The change from bank to loose volume is the swell of the excavated material The change from bank to compacted is the shrink of the excavated material Bank-----Swell-----Loose Bank-----Shrink-----Compacted If you need to remove the excavated material it would help to know the swell percentage for the soil you are excavating.

If your excavation was 15 m3. Your volume size would be 1.15 x 15 = 17.25 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.
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 = 2 5 and At = 15 * 15 = 225, and D = 5. Therefore, the volume is: = 542 cf or 20.0 cy. This is 1.5 cy more than the 18.5 cy we calculated using the average width and length, or 8% more.
