Corridors , staircases, elevators, heating systems, air conditioning and electrical systems belong to the most important inner elements of a skyscraper. Although the outside structure can be completed in a few weeks it may take years to finish the whole building.

Pumps bring clean water to all parts of the skyscraper, the drainage system carries away water and waste materials.

Air conditioning and heating systems control the temperature in the building the whole year round. Electrical systems provide power and communication throughout the building and wires carry electricity to each floor. Elevators are the most important systems of a skyscraper. They carry people up and down at speeds of up to 500 metres per minute.
