Sitework Estimation Fundamentals

Earthwork Cut and Fill

Basic principle: Cut volumes (excavation) and fill volumes (compaction) must balance on-site, or export/import costs apply.

Swell factor: Excavated soil expands 10-30% (depends on soil type). Account for this when calculating truck loads.

Compaction factor: Fill material must be compacted to specification, reducing volume 5-15%.

Equipment Costs

Track excavator (200,000 lb class): $150-250/hour

Dozer (D6-D8): $120-200/hour

Scraper: $200-350/hour

Dump truck: $75-120/hour (including driver)

Utility Trenching

Trench excavation (machine): $8-18/LF

Bedding and backfill: $3-8/LF

Trench restoration (pavement): $15-35/LF

Common Sitework Line Items

Clearing and grubbing: $2,000-6,000/acre

Rough grading: $1.50-4.00/CY

Fine grading: $0.50-1.50/CY

Erosion control (silt fence): $2.50-4.00/LF

Aggregate base: $15-30/ton (installed)
