construction site from a high vantage point, where workers are pouring concrete to create a foundation

construction site from a high vantage point, where workers are pouring concrete to create a foundation. A yellow concrete pump arm dispenses the concrete, which is then spread by workers with rakes across a large metal grid of rebar. The area has vertical metal supports along the far side, and the overall impression is one of a deep pit or excavation. The workers are wearing hard hats and protective boots. The lighting is bright, indicating it is likely daytime.
