Frequently Asked Questions About Excavation Contractors

Find answers to common questions about excavation contractors and hiring excavation professionals in the USA.

What is the difference between excavation and grading?

While often used together, excavation and grading are distinct processes:
Excavation: Primarily involves removing earth or other materials from a site. It's about digging down and creating space.
Grading: Focuses on shaping and leveling the ground to a specific slope or elevation. It's about adjusting the existing terrain.
For example, you might excavate a foundation and then grade the surrounding area to ensure proper drainage and a level surface for landscaping.

How do I calculate how much dirt I need for fill?

To calculate the volume of dirt (fill) needed, follow these steps:
  1. Determine the Area: Measure the length and width of the area you want to fill. Multiply them to get the area in square feet (or meters).
  2. Determine the Depth: Measure the difference between the existing grade and the desired grade (how much you need to raise the ground). This is the depth of fill required.
  3. Calculate Volume: Multiply the area (step 1) by the depth (step 2) to get the volume in cubic feet (or meters).
  4. Account for Compaction: Fill dirt compacts when it settles, so add 10% to 25% to the calculated volume to account for compaction. The exact percentage depends on the type of fill material.
For complex projects or uneven terrain, consult an excavation contractor or surveyor for accurate volume calculations.

What equipment is used for excavation?

Excavation projects employ various heavy equipment, chosen based on the job's scale and complexity. Common equipment includes:
  • Excavators: Versatile machines with a bucket, arm, and rotating cab for digging, lifting, and moving earth.
  • Backhoes: Similar to excavators but with a digging bucket on the back and a loader bucket on the front, ideal for trenching and smaller excavations.
  • Bulldozers: Powerful machines with a large blade for pushing earth, clearing land, and leveling surfaces.
  • Skid Steers: Compact and maneuverable loaders with various attachments (buckets, forks) for digging, loading, and grading in tight spaces.
  • Trenchers: Specialized machines for digging narrow trenches for utilities.
  • Dump Trucks: Vehicles for hauling excavated material to disposal sites.
The choice of equipment depends on factors such as the type of excavation, soil conditions, site accessibility, and project budget.

What are the different methods of excavation?

Excavation methods vary depending on project needs, site conditions, and available resources. Some common methods include:
  • Mechanical Excavation: Utilizing heavy equipment like excavators, backhoes, bulldozers, and loaders, suitable for most projects.
  • Hand Excavation: Using hand tools (shovels, picks) for smaller excavations or delicate work near utilities.
  • Blasting: Employing explosives to break up rock or hard materials, typically for large-scale projects.
  • Hydro Excavation: Using high-pressure water jets to loosen and remove soil, often used for locating utilities or delicate excavation.
  • Vacuum Excavation: Employing a vacuum system to suck up excavated material, suitable for safe excavation near utilities or in confined spaces.
Excavation contractors choose the most appropriate method based on factors like efficiency, cost, safety, and environmental impact.
