Rock Excavation Cost Specialty Grading

The cost of a typical residential excavation work averages at around 3500. Land excavators usually measure cost by cubic yards of dirt moved which can run anywhere from 50 to 200 for every cubic yard. Rock excavation can cost much more than the usual excavation. Depending on the site rock excavators can charge between 40-100 per cubic yard.
