An overhead view depicts an active construction site in the city of Lokoja, Nigeria, centered on a linear earth trench forming a foundation footing. One individual, seen from behind, is positioned within the trench. This person wears a white hard hat, a yellow long-sleeved shirt, a neon yellow high-visibility safety vest with reflective stripes, dark trousers, and dark footwear. They are oriented away from the camera, moving or standing on a freshly poured concrete footing at the bottom of the trench. The trench itself is excavated into earthen soil, with irregular, crumbling walls. Piles of loose dirt, rocks, and concrete debris are visible along both sides of the trench at ground level. Sections of the trench bottom are filled with wet, light grey concrete, forming a continuous footing. A faint white dashed line, possibly a string line, is embedded or laid across the wet concrete in the foreground. Several grey concrete blocks are visible near the individual's feet within the concrete-filled trench. No interactions with other individuals are observed. The environment appears dusty and consists predominantly of excavated earth and construction materials under daylight conditions.
