Excavating & Earthmoving Contractors – What Do They Do?

You commonly see bulldozers, dump trucks and other heavy machinery in building residential and commercial projects. In construction, excavation contractors do much more than haul dirt around. They have responsibilities such as site preparation, grading, trenching and many other earthwork tasks. They also operate some very large pieces of heavy earthmoving equipment.

Worksite Preparation

The excavating and earthmoving contractor starts after the surveying crew determines a construction project’s house and lot boundaries. The contractor prepares the worksite by removing the soil to the depth needed for the new foundation and ensuring stable ground for the building through compaction tests and compaction with equipment, if necessary.

The excavation requirements are precise, so excavating contractors can create stable soil suitable for foundations. Besides residential construction, excavation work is employed in foundations, roads and driveways, sewer lines, drainage and landscaping projects.

Contracting and Subcontracting

Excavation contractors manage their business and are considered subcontractors as their job is usually just one part of a bigger project. The excavation contractor will simply take care of the excavation work and won’t oversee the entire project. Excavation contractors often work under the supervision of general contractors, who manage the whole project.


Part of the job of an excavation contractor is earthmoving. Depending on the equipment the contractor owns or leases, he can build roads, grade roads, dig ponds and sewers, excavate ditches for utilities and operate trenchers for the pipe system beneath the ground. Excavation contractors create terraced drainage on farming land and construct earthen dams.

Heavy equipment and operators

Excavation equipment can be expensive, and insuring them may add to the cost. On average, a small to mid-size excavation contractor will often own or lease a couple of large front-end loaders, bulldozers, backhoes, compactors, trenchers and skid steers. Most excavation contractors have their own large dump trucks to haul away excess dirt. Also, most contractors will hire skilled or new operators and train them on the job. Interestingly, many excavation contractors were heavy equipment operators before.
