The towering buildings that fill our cities definitely weren''t built in a day. Skyscrapers are huge construction projects full of complicated steps. From drilling anchor holes and erecting steel beams to laying acres and acres of concrete, it takes lots of people and lots of smarts to build a vertical city. Readers will love putting on their hard hats and seeing the construction for themselves through vivid photographs and diagrams of a building on its way from its beginning on an empty lot to a monster skyscraper touching the skies.
