How to Use This Calculator

Enter excavation dimensions (length, width, depth in meters) from the site remediation plan.
Set soil bulk density and select disposal type (landfill, soil treatment facility, or on-site treatment).
Review excavated volume in cubic yards, soil tonnage, and number of truck loads.
Check estimated excavation, transport, and disposal costs per ton and total cost.
Add mobilization and site restoration costs to complete the project budget estimate.

How the result changes with Excavation length (m)

Excavation length (m)	Excavation volume (yd³)	Total project cost ($)	Cost per yd³ ($)
101	8,719	$983,345.00	$113.00
351	30,300	$3,403,134.00	$112.00
650	56,111	$6,297,202.00	$112.00
900	77,692	$8,716,991.00	$112.00

Excavation length (m): Length of the excavation area in meters.
Excavation width (m): Width of the excavation area in meters.
Excavation depth (m): Depth of contaminated soil to remove. Costs increase significantly below 3m.
Soil bulk density (t/m³): In-place bulk density. Sand ~1.6, clay ~1.4, gravel ~1.8 t/m³.
Disposal type (0-2): 0 = non-hazardous (Subtitle D), 1 = hazardous (Subtitle C), 2 = thermal treatment.
Haul distance one-way (miles): Distance from site to disposal facility.
Contingency (%): Contingency factor for unknowns. 10-20% typical for remediation.

Excavation volume (m³): Total excavation volume including 10% overbreak.
Excavation volume (yd³): Volume in cubic yards (US standard for bidding).
Soil weight (tons): Total weight in US short tons for disposal facility.
Truck loads: Number of 20 yd³ end-dump truck loads.
Excavation cost ($): Cost to excavate soil.
Disposal cost ($): Landfill tipping or treatment fees.
Hauling cost ($): Transportation cost to disposal facility.
Backfill cost ($): Clean fill import, placement, and grading.
Environmental monitoring ($): Dust control, air monitoring, and decontamination.
Total project cost ($): Total estimated cost including contingency.
Cost per yd³ ($): All-in cost per cubic yard of soil remediated.

Identify Input Parameters
4 parameters
Excavation length (m) = 30, Excavation width (m) = 20, Excavation depth (m) = 3, Soil bulk density (t/m³) = 1.6 = 7 input(s) provided
Calculate Excavation volume
Excavation volume = grossVolume * 1.30795
2590 = 2590
Calculate Total project cost
Total project cost = subtotal + contingency
296125 = $296,125
Calculate Cost per yd³
114 = $114
Calculate Excavation volume
Excavation volume = netVolume * 1.1
1980 = 1980
Calculate Soil weight
Soil weight = soilTons * 1.10231
