How much does excavation cost?

Excavation rates: Sand/loose soil: $10-15/cu yd (easy digging). Clay/compact: $15-25/cu yd (moderate). Rock/hard material: $40-100/cu yd (requires jackhammer/blasting). By project: Pool excavation (600 cu yd): $6K-12K. Basement (300 cu yd): $4K-8K. Grading/leveling: $5-15/cu yd. Trenching: $10-30/linear ft. Hauling: $200-400/truck load (12 cu yd).

How many cubic yards can a dump truck hold?

Dump truck capacity: Standard dump truck: 10-12 cu yd (most common). Large truck: 14-16 cu yd (commercial). Small truck: 5-7 cu yd (residential). Conversion: 1 cu yd ≈ 2,000 lbs (wet dirt). 1 truck load ≈ 10-12 tons. Example: 200 cu yd excavation ÷ 12 cu yd/truck = 17 truck loads needed. Cost: 17 loads × $250/load = $4,250 hauling.

What factors affect excavation cost?

Cost drivers: Soil type: Rock 4× more than sand ($40 vs $10/cu yd). Access: Difficult access +60% cost (tight, steep, no equipment access). Depth: Deeper = slower, more equipment time (+20-30% for >8 ft). Haul distance: 20 miles $400+/load. Site prep: Tree removal $500-2K/tree, grading $1K-5K. Permits: $500-2K for large excavations. Bottom line: Easy sand excavation $10-15/cu yd, rock in tight access $60-100/cu yd (6× more expensive).

Expert Tips

Excavation Costs $1,500-5,000 for Typical Projects: Small pool dig: $1,500-3,000. Foundation: $2,500-5,000. Large basement: $10,000-20,000+. Costs: Equipment rental $200-500/day, operator $50-150/hour, disposal $30-50/ton. Rocky soil adds 30-50% cost vs soft soil.
Call 811 Before Digging (Utility Location): Free service marks underground utilities (gas, electric, water, sewer, cable). Required by law 2-3 business days before digging. Hit gas line = $10,000-50,000+ repair + legal liability. Always call, even for small projects.
Soil Volume Formula: Length × Width × Depth: 20ft × 10ft × 3ft deep = 600 cubic feet = 22.2 cubic yards. Order 10-15% extra for settling and waste. Excavated soil expands 30-40% (more volume when loose vs compacted).
Disposal Costs Often Equal Excavation Costs: Hauling dirt: $30-50 per cubic yard. 50 yards excavated = $1,500-2,500 disposal. Options: Reuse on-site (grading), free fill ads, municipal yard waste facility (cheaper). Clay/contaminated soil = higher disposal fees.

Essential Fundamentals — Excavation planning

Volume Calculation

Cubic Yards Formula: Calculate cubic feet: Length × Width × Depth (all in feet). Convert to cubic yards: Divide by 27. Example: 30ft × 20ft × 4ft = 2,400 cu ft ÷ 27 = 88.9 cubic yards. Round up for material orders.
Soil Expansion Factor: Excavated soil takes up more space when loose. Clay expands 35-40%. Sand/gravel 20-25%. Topsoil 25-30%. Plan disposal capacity accordingly. 100 yards in ground = 125-140 yards hauled away.

Advanced Strategies — Cost optimization and safety

Project Planning

Timing Matters: Excavate during dry season to avoid mud, equipment stuck, drainage issues. Wet soil harder to dig, costs more, takes longer. Schedule permits 2-4 weeks early.
Equipment Selection: Small projects: Mini excavator $200-400/day. Large projects: Full-size excavator $400-600/day. Backhoe more versatile for trenching. Rent by week for better rates.
Disposal Strategy: Reuse clean fill on-site for grading saves hauling costs. Post "free fill" ads for excess soil. Test for contamination before spreading—contaminated soil requires expensive disposal.
