Pile Capacity Calculator
One pile from the soil layers: the inputs on top, the pile in the soil drawn, shaft and base resistance, the working and ULS capacity, every check with its clause, and a step-by-step calc sheet.
SANS 10160-5 Table B.2 · EN 1997-1 7.6 · SANS 10100-1 4.7.4.3 · the α / β coefficients are practice values you can see on the sheet

One pile here, the whole foundation in STATIX
The STATIX 3D suite carries the column loads down to the pile caps and the piles. The suite is in development; this calculator is free today.
