A construction worker in a yellow hard hat and orange safety vest positions a piece of lumber vertically against a yellow wall. He holds the lumber with his gloved hands and looks up at the top of it. The wall is composed of stacked, yellow, rectangular pieces of material. The construction site has rebar grids and other construction materials scattered around. Another worker in a yellow hard hat and orange vest is visible in the lower right of the frame, working near a stack of the yellow materials.
