How much is a 1" elevation miss actually costing you?

Contractors and sellers routinely hand over sites that are "close enough" on grade. Even a 3-inch variance on a 50-lot deal can quietly burn six figures in imported fill, compaction, and loan carry. See what you're exposed to.

Loan carry ($/day)

Tennessee residential averages. Fill = import + compaction. Cut = export only. Production rate: 500 cu yd/day.

Why these numbers matter

The exposure above isn't theoretical — it lines up with how the construction industry already prices grading risk.

±0.75"

Industry tolerance for fine grade under residential slab pads. A fully spec-compliant site can still be carrying up to 1.5" of total variance.

ACI 117-10

85%

of construction projects come in over budget — earthwork is a top driver, which is why a 20% sitework contingency is the industry norm.

Construction industry research

30%

of all on-site work is rework. 70% of that traces back to bad input data caught after dirt has already moved.
