In constructing of a building, it is possible to cast the floors and walls as well as the framework directly on the spot where they are to stand. Building forms a monolith. Last one is a large artificial stone composed entirely of concrete that has been shaped within wooden molds fitted together perfectly. To cast all parts in place, a builder has to use many forms. They are removed as soon as the concrete has set. Before beginning another work, concrete must be given plenty of time to harden. In order to save time, a builder may prefer to use a number of standardized concrete units. Individual members can be pressed. Also different sections of the building can be prefabricated.
