two men working at a construction site

two men working at a construction site. A man wearing a multi-colored shirt and shorts is shoveling sand inside a structure made of concrete blocks. The structure has empty window and door frames, revealing a view of fields and distant hills. Another man, wearing a blue shirt and a baseball cap, is using a metal tool to work on a pile of sand. The ground inside the structure is covered in sand, and shadows are cast by the walls. The scene appears to be outdoors on a sunny day.
