What Does the Excavation Time Calculator Do?

The Excavation Time Calculator takes the following inputs:

1. Excavation Volume (m³): The total volume of soil or material to be excavated.
2. Excavation Rate (m³/hour): The rate at which the machine or equipment excavates per hour.
3. Cost per Hour ($): The cost of operating the excavation equipment per hour.

Outputs:

• Excavation Time: The total time required to complete the excavation.
• Total Cost: The overall cost of the excavation process.

Formula for Excavation Time

The formula to calculate the Excavation Time is:

$\text{Excavation Time} = \frac{\text{Excavation Volume}}{\text{Excavation Rate}}$

Where:

• Excavation Volume = Total material to be excavated (in cubic meters, m³).
• Excavation Rate = Rate of excavation per hour (m³/hour).

Formula for Total Cost

Once the excavation time is calculated, the Total Cost can be determined using the formula:

$\text{Total Cost} = \text{Excavation Time (hours)} \times \text{Cost per Hour (\$)}$

Where:

• Excavation Time = Time calculated from the previous formula (in hours).
• Cost per Hour = Operating cost of the excavation equipment (in dollars per hour).

Example Calculation

Let’s assume the following values:

• Excavation Volume: 300 m³
• Excavation Rate: 50 m³/hour
• Cost per Hour: $100

Step 1: Calculate Excavation Time

Using the formula:

$\text{Excavation Time} = \frac{\text{Excavation Volume}}{\text{Excavation Rate}}$

Substitute the values:

$\text{Excavation Time} = \frac{300}{50} = 6 \, \text{hours}$

Step 2: Calculate Total Cost

Now calculate the total cost using the formula:

$\text{Total Cost} = \text{Excavation Time} \times \text{Cost per Hour}$

Substitute the values:

$\text{Total Cost} = 6 \times 100 = 600 \, \text{\$}$

Final Results:

• Excavation Time: 6 hours
• Total Cost: $600

FAQ

What is excavation rate?

Excavation rate refers to the speed or volume of earth or rock material removed per unit of time during excavation work. It's typically measured in cubic meters per hour (m³/hr) or cubic yards per hour (yd³/hr).
