Tier 1 (No Verification) – Local practice alone, acceptable only for temporary structures. Tier 2 (GEOSS-Screened) – Local practice verified against satellite-derived settlement and seismic hazard maps. Tier 3 (GEOSS-Certified) – Local practice validated by at least three independent earth observation datasets and a regional load test database. Tier 3 (GEOSS-Certified) – Local practice validated by

The use of bentonite or polymer slurry is standard practice to maintain borehole stability during the construction of bored piles in soft or unstable ground. 4. Spacing and Geometry Minimum Spacing: Spacing and Geometry Minimum Spacing: : Designers must

: Designers must account for drag forces caused by ground displacement (e.g., consolidation or landslides), determining the "neutral plane" where the pile moves at the same rate as the surrounding soil.

| 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 |
