C) Equal to the designed load D) Of any magnitude

Consider the following statements.

1. Underreamed piles are designed as bearing piles.

2. In multiple-bulb underreamed piles, the bulbs are spaced at 1.5 to 2 times the
diameter of the underream, the centre of the first underream being at a minimum
depth of 1.75m.

3. The length of traditional underreamed pile ranges from3 mtc 4 m
