Excavation Contractors in Bismarck, North Dakota
Site excavation, grading, and earthwork..
Excavation contractors handle site preparation, foundation digging, grading, trenching for utilities, pond construction, and land reshaping using heavy equipment like excavators, backhoes, and bulldozers. Excavation is the critical first step in most major construction projects — accuracy in grade, depth, and compaction directly affects the success of everything built on top. Before any digging begins, the site must be surveyed and all underground utilities (gas, electric, water, sewer, telecom) must be marked through your state's 811 "call before you dig" service. Proper erosion control and stormwater management are required by local ordinances on most excavation projects.

General Excavation FAQs
How much does excavation cost?
Excavation costs depend on the scope and equipment needed. Hourly equipment rates: mini excavator $100–$175/hr, standard excavator $150–$250/hr, bulldozer $150–$300/hr. Foundation excavation for a new home: $3,000–$10,000. Utility trenching: $5–$15 per linear foot. Grading and site preparation: $1,500–$5,000 for a residential lot. Pond excavation: $3,000–$10,000+ depending on size. The estimate should include equipment, operator, hauling of excess material, and final grading. Call 811 before any digging to have underground utilities marked.
Do I need to call 811 before digging?
Yes — 811 is required by law in all 50 states before any excavation or digging project. Call 811 at least 2–3 business days before work begins (some states require more notice). The service is free and sends utility locators to mark underground gas, electric, water, sewer, and telecom lines with colored flags or paint. Hitting an underground utility can cause explosions, electrocution, flooding, service outages, and thousands of dollars in repair costs — plus legal liability. Your excavation contractor should confirm 811 has been called and marks are visible before any digging starts.
