Excavation is a fundamental part of new construction projects. Each construction service has different cost factors, such as the equipment used and how deep you want the hole to be.
Hence, it’s essential to consider them when calculating the average excavation costs per square foot or cubic yard.
This article discusses what the cost of land excavation is for the concrete foundation. Other things can determine those costs, too, so dive into this page to learn everything about digging costs!
Land Excavation Costs
Many things determine the excavation cost. Excavation tends to cost between $1,239 to $4,017.
Small projects that don’t have walls near the place and don’t require much equipment can even cost you less, so everything depends on the construction process that needs to be done and the type of equipment they use.
The national average cost for excavation work is $3,000, so expect that price when looking for a contractor for your place’s foundation.
Excavation Cost Factors
- Equipment needed for the excavation process
- Ease of access of the construction site
- The size of the area
- The amount and the type of soil to be excavated
- Type or purpose of the project
When Do You Need to Excavate Land
Excavation is needed when building a foundation site. Residential work tends to need an excavator when adding a pool to your place or including a full basement.
Yet, whenever there’s a new project, the contractor tends to ask if the owner wants a basement and add that to the total cost.
You can make a significant home improvement just by digging a hole. Whether you want to add a basement, fix the poured concrete foundation, or have more space, hiring these services brings you considerable benefits.
Foundation for New Construction Cost
The work includes the cost of excavation, grading, and the number of footings.
Costs can significantly depend on some factors such as your location, size of your home, and the type of foundation you need, whether a slab foundation, Pier and Beam foundation, crawl space foundation, full basement foundation, garage foundation, etc.
Homeowners can expect to spend between $5,200 to $13,000 for concrete slab foundations.
There are 2 main types: The monolithic slab and the stem wall.
- Monolithic Slab – $5,200 to $13,000.
- Stem wall – $7,000 to $21,000
Pier & Beam Foundation Cost
Before slab foundation, pier and beam are some of the most common types of foundation used because they are more budget-friendly in terms of maintenance and repair. They keep the house elevated to protect it against floods and molds.
Price can range from $8,000 to $15,000 or $6 to $12 per square foot.
Crawl Space Foundations
Crawl space is a mixture of stem walls and posts and piers. This can cost $5 to $16 per square foot or $7,000 to $21,000 on average. This type of foundation is useful for flood-prone and earthquake-prone areas.
Basement Foundation Cost
Installation of the basement can cost you $10,000 to $175,000, though the most expensive foundation to build, this is still a cheaper option than adding an extra room for storage.
Garage Foundation Cost
Constructing a garage can cost around $17,000 and $39,000, including the foundation. A garage that is attached to your property and relatively cheaper compared to the detached one.
Consult An Excavation Expert
You need to know other things about the labor you hire and the materials you use to dig a hole in a crawl space. If these things are overwhelming for you, you can ask your local contractors to guide you in what you need to do.
Other things must be done at the job site after excavating with a backhoe loader or an excavator. Digging can leave a lot of dirt in your house, especially if there is rocky soil. You also need to fill the hole after you excavate.
Call a professional contractor to evaluate your excavation and construction needs.
