Description

The image is a diagram showing the process of constructing a building using a crane. There are two cranes in the image, one on the left side and the other on the right side. The cranes are lifting steel beams, which are being used to construct the building. The diagram is divided into three sections, each showing a different stage of the construction process. The first section shows the initial stage, where the steel beams are being lifted into place. The second section shows the middle stage, where the beams are being assembled into the building's structure. The third section shows the final stage, where the building is completed and ready for use.
