group of people standing around a large pile of sand inside what appears to be a warehouse or large indoor space. The group consists of several individuals, some wearing casual clothing and others in uniforms. There is a large pile of sand in the center of the scene, with construction materials like planks and concrete blocks scattered around it. The background reveals warehouse doors and windows, as well as metal shelves and a red door. The group seems to be engaged in a conversation or observing something within the sand pit, as they are focused on the central area.
