There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

After you successfully remove your boulder, you have a few options for what to do to get rid of it. You can rent a dumpster if your yard has many boulders or if you’re planning a larger project. You can even save the boulder and reuse it elsewhere on your property to save on landscaping costs. A few ideas include using the boulder as a natural, abstract statue, breaking it into smaller pieces to line your garden bed, or offering it to a landscaping company that could reuse it for another project.

The average cost of excavation is approximately $3,200, with typical projects ranging from $500 to $15,000. Depending on the contractor, you may be charged between $50 and $200 per cubic yard or an hourly rate of $40 to $180 for an excavation specialist. The total cost is influenced by several factors, including the project size, the amount of soil to be removed, and the soil's condition. Hard soil, tree roots, or excessive rocks and clay can increase the price, potentially adding $200 to $1,200 to the final bill. Other factors that can drive up costs include the presence of nearby structures that complicate the work or tight spaces that require manual excavation instead of heavy machinery.

Consultation with the local government helps identify necessary permits, avoid project delays or legal issues, and protect project integrity.
