Step 1: CPT Data

Please upload a CSV or TXT file containing the CPT data in the order indicated below. Note the units required. The CPT profile must extend below the maximum pile depth.

The first unit weight entry will be used throughout if no other unit weights are entered.

The depth increment from this CSV file controls the accuracy of the calculations (suggested increment ≤ 0.1 m).

Depth (m) Cone resistance qt (MPa) Cone sleeve friction, fs (kPa) Unit weight (kN/m³)
