Fine Adjustment and Leveling

What happens here
Once a stone is initially placed, fine adjustments are often necessary to achieve the optimal fit and alignment. The excavator's grapple may gently push, pull, or rotate the stone to settle it more firmly against its neighbors. A worker on the ground plays a crucial role here, using a long spirit level to check the horizontal level and vertical plumb of the stones. The worker provides visual cues or verbal instructions to the excavator operator, who then makes precise, subtle movements with the machine to adjust the stone. This iterative process of placement, adjustment, and leveling ensures the wall is structurally sound and aesthetically pleasing. A plate compactor is visible nearby, suggesting that base layers or backfill might be compacted, though it's not actively used in this segment.
Goal: Ensure proper alignment, level, and stability of each stone
