Frequently Asked Questions About Excavation Contractors

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

What should I do before excavation starts?

Prior to the start of excavation, take these essential steps:
  • Clearly Define the Scope: Outline the project's goals, including the excavation area, depth, grade, and intended use.
  • Obtain Necessary Permits: Research and acquire any required permits from your local authorities.
  • Mark Utility Lines: Contact your utility companies to locate and mark underground utilities to prevent damage.
  • Communicate with Neighbors: Inform your neighbors about the project's timeline and potential noise or disruptions.
  • Prepare the Site: Clear any obstacles, such as vegetation, furniture, or structures, from the excavation area.
  • Discuss Safety Protocols: Review safety procedures with the contractor to ensure a safe work environment.
Taking these steps helps ensure a smooth and successful excavation project.

What is the best time of year for excavation?

The ideal time for excavation can depend on your location and climate. Generally:
  • Spring and Fall: Often considered favorable due to moderate temperatures and drier soil conditions.
  • Summer: Can be suitable, but hot weather can make working conditions challenging and might require additional measures (shade, hydration) for workers.
  • Winter: Excavation in winter can be more difficult due to frozen ground, snow, and potential delays caused by inclement weather. It might also require specialized equipment or techniques.
Consult with your excavation contractor to determine the best timing for your project, considering local weather patterns and potential seasonal constraints.

Do I need a permit for excavation?

Permit requirements for excavation vary widely depending on your location and the project's specifics. Generally, permits are needed for:
  • Excavations Deeper Than a Certain Depth: This varies by jurisdiction, usually around 5 feet.
  • Excavations Near Utilities: Digging near buried utilities (gas, water, electric) often requires permits and utility locates to prevent damage.
  • Excavations Affecting Public Property: Projects impacting sidewalks, roads, or other public areas typically require permits.
  • Excavations in Environmentally Sensitive Areas: Projects in wetlands, floodplains, or other sensitive areas might need special permits.
Contact your local building department or planning authority to determine the permit requirements for your excavation project. Failure to obtain necessary permits can result in fines or project delays.

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.
