Frequently Asked Questions About Excavation Contractors

How do you handle soil disposal after excavation?

Responsible soil disposal after excavation is essential. Excavation contractors typically handle it by:

• Hauling to Designated Disposal Sites: Transporting excavated material to approved landfills or recycling centers.
• Recycling or Reuse: If suitable, some excavated soil might be recycled for other projects or reused on-site for landscaping or backfilling.
• Complying with Regulations: Adhering to local and environmental regulations for soil disposal to prevent contamination or illegal dumping.

Discuss disposal plans with your contractor, inquire about recycling options, and ensure they handle waste responsibly.

What is a soil engineer, and do I need one?

A soil engineer is a professional specializing in analyzing soil properties and their behavior under various conditions. They play a crucial role in:

• Determining Soil Suitability: Assessing whether the soil can support the intended structure or load.
• Recommending Foundation Types: Advising on the appropriate foundation design based on soil characteristics.
• Addressing Drainage and Erosion Issues: Providing solutions to manage water runoff and prevent erosion.
• Evaluating Slope Stability: Assessing the risk of landslides or soil movement on slopes.

You might need a soil engineer for projects involving:

• Building on challenging soil types (expansive clay, loose sand, etc.)
• Constructing large or complex structures
• Excavating near slopes or retaining walls
• Addressing drainage or erosion concerns

Your excavation contractor or local building department can advise if a soil engineer is necessary for your project.

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.

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.
