Volume calculations Cubage
Excavation volume calculations are used to determine the amount of soil to be removed or filled during earthworks (excavation) in a construction project. These calculations are very important in determining project costs, planning the necessary equipment and labor, and creating a project schedule.Why is a Cubage Calculation Made ?
- Cost determination: The amount of soil to be excavated or filled directly affects the project cost.
- Equipment and workforce planning: Cubage calculations are made to determine the required equipment (excavators, trucks, etc.) and workforce.
- Material requirement: Where the excavated soil or stone will be dumped and how much filling material will be required is determined by the cubage calculation.
- Project schedule: The duration of excavation work depends on the volume and equipment used. Therefore, an accurate cubage calculation plays an important role in creating the project schedule.
How to Calculate Cubage ?
Cubage calculations are usually done with the following methods:
Cross-section method:
Cross-sections are taken at certain intervals in the project area.
The area of each cross-section is calculated.
The volume between two consecutive cross-sections is found by multiplying the average of the areas of these two cross-sections.
The sum of these calculations made for all cross-sections is the total cubicage.
3D modeling:
A 3D model of the project area is created.
The area to be excavated is determined on this model and the volume is automatically calculated.
Cubage calculation software:
Special software automatically performs cubicage calculations by taking cross-section data.
Things to Consider in Cubage Calculations
Soil structure: The type of soil affects the difficulty of excavation and therefore the cost.
Excavation depth: As the excavation depth increases, the volume also increases.
Slope: The slope of the land can make excavation work difficult.
Presence of structures: Existing structures can affect the excavation process and change the volume calculations.
Water level: The groundwater level can make excavation difficult and require additional precautions.
Importance of Cubage Calculation
Cubage calculation is very important for the successful completion of construction projects. An accurate and detailed cubage calculation helps to keep project costs under control, make the work schedule more realistic and foresee potential problems.
In short, cubage calculation is a calculation made to determine the amount of excavation or filling work to be done in a construction project. This calculation has an important role in all stages of the project.
