Four construction workers, wearing hard hats and safety vests, are filling cylindrical molds with concrete in an outdoor environment. One worker in an orange vest is using a vibrator to compact the concrete in the molds. The others pour the concrete from a wheelbarrow. Behind them is a large transport truck and trailer on a dirt road. The sky is clear and blue. The ground is dusty and dry. The setting appears to be a construction site in a mountainous or desert region.
