The video shows a construction worker operating a CSM M 740 machine on the grounds outside a brick building. The building has the number "15" marked on it. The worker is wearing a white hat and a bright yellow safety vest. Next to the machine is a pallet of bags, labeled "CONCRETO 500," and a pile of sand. There are also some empty bags on the ground near the machine. The machine has a hopper into which the worker seems to be loading materials. The ground is wet, and there is green grass in the foreground. The audio suggests the machine is in operation.
