Initial Paver Placement and Layout

What happens here

The installation begins with workers carefully unloading large, dark grey rectangular concrete pavers from a pallet. Each paver is then individually lifted and precisely placed onto a prepared sub-base, which appears to be a layer of compacted gravel or crushed stone. The initial pavers are laid to form the foundational rows of the patio, starting adjacent to what looks like a pre-existing retaining wall or a border structure. Workers wear gloves for better grip and protection while handling the heavy pavers.

Goal: Establish the first rows of patio pavers on the prepared sub-base.
