Frequently Asked Questions About Excavation Contractors

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

How long does an excavation project take?

The duration of an excavation project varies significantly depending on factors like:
  • Project Size and Scope: Larger, more complex excavations naturally take longer.
  • Soil Conditions: Rocky or challenging soil types can slow down progress.
  • Site Accessibility: Limited access might require more time for maneuvering equipment and hauling materials.
  • Weather: Inclement weather can cause delays.
  • Permitting and Inspections: Waiting for permits or inspections can extend the timeline.
Your excavation contractor can provide a more accurate estimate after assessing your project's specifics.

How do I know if I need excavation for my project?

Several project types often necessitate excavation:
  • New Construction: Laying foundations, basements, or underground utilities for new buildings.
  • Home Additions: Creating space for new rooms, basements, or extensions.
  • Landscaping: Leveling ground, creating slopes, installing retaining walls, or digging for ponds or pools.
  • Drainage Improvement: Installing French drains, drainage ditches, or swales to manage water runoff.
  • Utility Installation or Repair: Laying new water, sewer, gas, or electrical lines, or repairing existing ones.
  • Demolition: Clearing debris and preparing the site after demolishing a structure.
If your project involves altering the ground level or installing underground features, excavation is likely required.

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 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.
