In coastal locations such as this one, the upper soil layers often consist of soft sediments with low bearing capacity that would give way under load. A conventional shallow foundation would have led to uneven settlement here and, consequently, to damage to the building.  <\/span><\/p>\n\n<p><span style=\"font-weight: 400;\">To eliminate this risk, <\/span><b>24 piles, up to 9 meters long,<\/b><span style=\"font-weight: 400;\"> were driven into the ground. The goal was to specifically transfer the building\u2019s loads past the near-surface, non-bearing layers and into deeper, stable soil layers.
