Geoss Guidelines On Local Practices For Pile Foundation Design And Construction Verified [2021] -

| Pile Type | Typical Working Load | Common Use | |-----------|----------------------|-------------| | Steel H-pile | 300 – 1000 kN | Medium loads, low headroom | | Spun concrete pile (precast) | 600 – 3000 kN | High loads, dense sand/old alluvium | | Bored pile (wet or dry) | 1000 – 6000 kN | Large diameters, variable ground | | Barrettes (diaphragm wall elements) | 4000 – 15000 kN | Very high loads, deep basement foundations |

Addressing downdrag requires careful consideration of soil consolidation, pile installation sequence, and long-term performance—areas where generalized codes may provide insufficient guidance without local calibration. | Pile Type | Typical Working Load |
