What Is Excavation?
Excavation is the process of removing soil, rock, and other materials from a site to prepare it for construction, foundations, or other improvements. It is one of the most critical construction processes, as it determines the suitability of a foundation for any project. Professional excavation typically involves:
- Site clearing and preparation
- Digging trenches, cavities, or tunnels
- Grading and leveling land surfaces
- Moving and redistributing soil
- Creating foundations for structures
- Installing drainage systems and utilities
Excavation involves heavy machinery like bulldozers, excavators, backhoes, and forward loaders. Only experienced engineers and contractors can determine the excavation work necessary for a project, which is why it is important to work with licensed professionals for any land clearing or excavation project.
How Much Does Excavation Cost?
The national average cost for excavation falls between $1,660 and $6,716, with most homeowners paying around $3,988. However, costs can range from as low as $500 for small jobs to $15,000 or more for large, complex projects.
Average Excavation Costs by Project Type
Excavation is typically priced per cubic yard of dirt removed, with costs ranging from $50 to $200 per cubic yard for residential projects. Small projects cost less than big ones, and the cost is higher for projects with difficult-to-reach areas than for easily accessible ones.
How Much Does Basement Excavation Cost?
Basement excavation cost typically ranges from $5,000 to $15,000, depending on the size of the basement, soil conditions, and accessibility. You might need this type of excavation to dig out a new basement for construction, fix foundation issues, or add waterproofing to an existing structure.
For new construction, the average cost to excavate a basement ranges from $1,500 to $6,000, though larger basements can cost as much as $10,000. Rocky soil conditions, common in parts of Central Oregon, can push costs even higher—potentially up to $30,000 for extensive rock removal.
Central Oregon Soil Considerations
Central Oregon properties often have volcanic rock, clay deposits, or variable soil conditions that can significantly impact excavation costs. Areas with high rock content may require specialized equipment like hydraulic breakers, adding 10-30% to the project cost. Always get a site assessment before finalizing your budget.
What Factors Affect Excavation Cost?
Several factors influence the final cost of an excavation project. Understanding these variables helps you budget accurately and avoid surprises:
Size of Area and Accessibility
Excavators calculate costs based on the cubic yards of dirt moved or removed. A small excavating job can cost about $100 per hour, while larger jobs range between $1,500 and $5,000. Additionally, small, difficult-to-reach spaces and challenging terrain can increase the price significantly.
Soil Type and Composition
Ideal excavation soil is loose and free of rocks and plant material. Soil with many rocks, clay deposits, or high water tables can increase costs by $200 to $1,200. Rocky soil may require blasting or drilling, while sandy soil might need additional stabilization measures.
Equipment and Machinery
It generally costs $100 to $250 per hour to rent excavation equipment with an operator. Larger machine rentals are more costly, but they are also more efficient, which can reduce labor costs. Common equipment includes backhoe loaders, bulldozers, excavators, trenchers, and skid-steer loaders.
Grading and Leveling Needs
Grading and leveling generally cost between $400 and $6,500. Grading helps adjust the slope and soil elevation before construction begins, creating an even surface and solid foundation. The average grading cost is $500 to $1,000 for small yards and $1,000 to $5,000 for larger home lots.
Labor Costs
Labor makes up a large portion of excavation costs. Contractors typically charge $120 to $150 per hour or $50 to $200 per cubic yard. Hourly rates depend on the project layout, geographical location, and challenges present in the job.
Permits and Regulations
Excavation projects often require permits and must comply with local building codes. Permits typically cost $50 to $400, and you may also need a land survey ($400 to $550) to ensure it is safe to dig. Always consult with local authorities for permit requirements before starting your project.
Breakdown of Excavation Costs
Here is a detailed breakdown of the average costs for different excavation processes:
| Excavation Process | Average Price |
|---|---|
| Land Clearing | $200 – $6,500 |
| Site Excavation | $50 – $200 per cubic yard |
| Land Leveling | $50 – $165 per hour |
| Dirt Removal/Hauling | $8 – $25 per cubic yard |
| Cut & Fill | $3 – $16 per cubic yard |
| Trenching | $450 – $1,300 |
| Machinery | $150 – $230 per job |
| Labor | $50 – $250 per cubic yard |
| Grading | $500 – $5,000 |
How Is Excavation Priced?
Excavation is typically priced per cubic yard of dirt removed. To calculate excavation costs, multiply the excavated zone's length, width, and depth to estimate its volume. Then multiply the total excavation volume by the price per unit.
Example Calculation:
If an excavated area has a length of 40 ft, width of 16 ft, and depth of 8 ft:
Volume = Length × Width × Depth
Volume = 40 × 16 × 8 = 5,120 cubic feet
Convert to cubic yards: 5,120 ÷ 27 = ~190 cubic yards
At $75/cubic yard: 190 × $75 = $14,250
A small job can cost around $100 an hour, while larger jobs can exceed $500 per hour. The time of year also influences excavation costs—contractors may offer lower prices during early Spring or late Fall when demand is lower.
Additional Excavation Costs to Consider
Beyond the base excavation cost, several additional expenses may apply to your project:
Soil Testing
$700 – $2,200Identifies pollutants and contaminants before digging
Land Survey
$400 – $550Required to identify property boundaries and underground utilities
Permits
$50 – $400Municipal permits for excavation work
Dirt Hauling
$8 – $25/cubic yardRemoving excess soil from the site
Rock Blasting
$40 – $100/cubic yardRequired for rocky terrain
Site Restoration
$500 – $3,000Grading, seeding, or landscaping after excavation
Tips to Save Money on Excavation Costs
Even if you cannot DIY the entire job, there are several ways you can save on excavation costs:
Work in the Off-Season
Schedule excavation during December, January, or February when contractors are less busy. However, confirm that frozen ground will not affect your project.
Get Multiple Quotes
Interview at least three different contractors to compare pricing. Remember, if a price is significantly lower than others, there may be a good reason.
Do Some Work Yourself
Handle simpler tasks like minor land clearing or debris removal to reduce labor costs. Always consult your contractor first.
Bundle Multiple Projects
Group similar projects together. If you need grading, land clearing, or trenching in separate areas, do it all at once to reduce equipment mobilization costs.
Call 811 Before You Dig
Contact the national call-before-you-dig number to have underground utilities marked. Damaging buried utilities can add significant costs to your project.
Frequently Asked Questions About Excavation Costs
How much can an excavator dig per day?
Excavators can dig from 350 to 1,000 cubic yards per day, depending on the type of excavation, bucket capacity, and the skill of the machine operator.
What is included in excavation?
Excavation typically includes site clearing, digging, grading, and soil removal. Different types include topsoil excavation, earth excavation, rock excavation, muck excavation, and trenching for utilities and foundations.
Should I excavate in the summer?
Seasons have little effect on when excavation can occur. However, inclement weather can prolong the job and increase costs. Those in rainy climates may prefer seasons with milder weather.
How long does excavation take?
For a foundation, excavation could take anywhere from three days to three weeks. Weather delays, inaccessible sites with boulders, or rough terrain can extend timelines. Clay soil is also more difficult to dig.
