Site had extremely loose alluvial soil, with SPTs of 3-7. The site was red-flagged and additional investigations were undertaken
to verify the low strength values. The client was educated about the poor soil condition and the increased costs of foundation
for the project. 2 options - either of 3m deep RCC bored piles, or 3.5m deep rammed steel piles were proposed.
The rammed piles were tested at site and the option was chosen for it's speed.
