All Excavation & Earthworks Calculators
Excavation Volume Calculator
earthworks
Estimate dig volumes for trenches, foundations, and site clearance, with soil swell factors to plan spoil removal and haulage.
Trench Volume Calculator
earthworks
Calculate trench excavation volume for utilities, footings, and drainage with rectangular or trapezoidal cross-sections. Includes soil swell factors and OSHA depth warnings.
Foundation Excavation Calculator
earthworks
Calculate foundation dig volume for slab, crawlspace, or basement with working room allowance and optional strip footing volume.
Topsoil Removal Calculator
earthworks
Estimate topsoil stripping volume, weight, and truckloads from area and strip depth for site preparation and grading projects.
Soil Swell & Shrink Calculator
earthworks
Convert between bank, loose, and compacted soil volumes instantly. Enter any one volume state to see all three with soil-specific swell and shrink factors.
Dump Truck Load Calculator
earthworks
Calculate how many dump truck trips you need with both volume and weight limit checks. Compares volume-limited and weight-limited trip counts.
Backfill Calculator
earthworks
Calculate backfill material needed after pipe installation with compaction factor and pipe displacement.
Cut and Fill Calculator
earthworks
Calculate cut and fill balance with swell and shrink factors for earthwork grading.
Spoil Pile Calculator
earthworks
Calculate spoil pile footprint, height, and staging area from excavated volume.
Excavation Cost Calculator
earthworks
Estimate excavation costs with itemized breakdown: dig, hauling, disposal, labor, equipment.
OSHA Trench Sloping Calculator
earthworks
Calculate OSHA-compliant trench slope setback and top width by soil type.
