The values and properties indicated in the table below can also be used instead of the bearing capaicty equations above. These values are given only as estimated values for preliminary analysis, for its respective soil materials. The values should only be used for scheme design calculations.
| Soil Material | SPT, N Value | Undrained shear strength, C (kN/m^2) | Assumed Bearing Capacity, qallow |
| Sand | N | 10N or 10N/2 if submerged | |
| Stiff Clay | C | 5.14 C/3 | |
| Rock | N | 10N or assumed 3000 kPa with FOS = 3 |
