    Mac-arthur piles are the heavy steel casing with a core is driven into ground. When the desired depth is reached, the core is withdrawn and a corrugated steel shell is placed in the casing. The last operation consists in filling and gradually compacting the concrete and withdrawing the casing.

    Though self compacting concrete is used, these bulbs may not be filled completely. So, reinforcement is lowered after concreting, after clearing the muck on top, if any, either by vibration or driving, so that concrete is forced into the bulb.
