Frequently Asked Questions About Excavation Contractors

What is the difference between a backhoe and an excavator?

A backhoe is a type of excavator that has a digging arm that faces backward, in addition to a front-mounted loader bucket. Standard excavators have a digging arm that faces forward and typically only have a digging bucket. Backhoes are more versatile for tasks like digging trenches, loading materials, and landscaping, while excavators are more specialized for digging and excavating.

How do you calculate excavation volume?

Calculating excavation volume is essential for determining material quantities and disposal costs. The method depends on the shape of the excavation:

• Rectangular Excavation: Volume = Length x Width x Depth
• Triangular Excavation: Volume = (0.5 x Base x Height) x Length
• Irregular Shapes: May require breaking the excavation into smaller, simpler shapes and calculating their volumes separately.

Online calculators or software can assist with complex calculations.
