The stone was worked using ground stone tools — hammerstones and grinding stones — to peck and grind along fault lines in the limestone.

This is slow work, but it is not technically mysterious: limestone fractures predictably along joints, and experienced workers would have known how to identify and exploit these natural lines of weakness to free large pieces.

The quarrying did not require metal tools or techniques beyond those available to skilled PPN craftspeople.

Transportation of the quarried pillars from the bedrock outcrops to the construction site would have required significant coordinated labor.

Moving a stone pillar weighing multiple tons across rough terrain without wheeled vehicles or draft animals is difficult but not impossible: wooden rollers, sledges, ropes, and the organized effort of many people working together are sufficient for the task.
