An excavation contractor uses equipment such as excavators, skid steers and dozers to dig foundations, grade land, clear vegetation, trench for utilities and haul or bring in soil and fill.
Yes. Underground utilities should be marked before excavation, typically by calling 811 in the United States. Ask the contractor who will make the request and how private lines, such as irrigation or septic, will be located.
Ask about equipment and experience with similar sites, how they will handle drainage and erosion control, and whether permits are needed. Confirm insurance and get a written scope that covers hauling and restoration.
Cost depends on the volume of soil moved, soil and rock conditions, site access, slope, hauling distances, disposal or fill material, erosion control and permit requirements.
Mark property lines and planned structures, request utility locates, and remove vehicles and items from the work area. Ask how lawns, driveways and nearby landscaping will be protected or restored.
