Frost & ground/ CALCULATOR

Foundation bearing and excavation elevations

Translate final grade, bearing depth and a working layer into site elevations and excavation depth.

Final adjacent grade elevationmUse the same project datum as every other elevation.

Bearing depth below final grademVertical distance from final grade to the underside bearing surface of the foundation.

Working layer below bearing surfacemmInclude only the approved layer excavated below the structural bearing surface.

Foundation bearing elevation

98.65 m

Planned excavation elevation

98.50 m

Excavation depth below final grade

1.50 m

One final-grade elevation and vertical dimensions at a single point. Existing grade, slopes, steps, over-excavation, replacement fill, tolerances, groundwater, shoring and safe excavation geometry are excluded. A survey control point and approved drawings govern site work.
