What is Construction?
{{unref|date=March 2012}} '''Construction''', also referred to as '''constructing''', '''engineering''' or '''building''', is the process of erection or assembly of any [[building]] or [[infrastructure]] on a site. In general, there are three types of construction:[[Image:Prefabricated house construction.gif|thumb|220px|Construction of a pre-fabricated [[house]].]] [[Image:Sky scraper construction.jpg|thumb|The town the construction]] [[Image:Construction site in Cologne, Germany (2017).jpg|thumb|The building on [[Cologne]], [[Germany]].]] # [[Building]] construction # Heavy/[[civil engineering|civil construction]] # [[Industrial]] construction Building construction is the process of adding structure to [[real property]]. Industrial construction, though a relatively small part of the entire construction industry, is a very important component. ==History== The first buildings were huts and [[shelter]]s, constructed by hand or with simple tools. As [[cities]] grew during the [[Bronze Age]], a class of professional craftsmen appeared. Occasionally, [[slaves]] were used for construction work. In the [[Middle Ages]], these were organized into guilds. In the 19th century, steam-powered [[machinery]] appeared, and later [[diesel]]- and [[electric]] powered [[vehicle]]s such as [[Crane (machine)|cranes]], excavators and bulldozers. Modern construction is consistently made of materials such as [[glass]], [[steel]], [[concrete]] and bricks. So it is easy to build simple forms like simple cubic forms. The new style of [[architecture]] is based on the economic basic principle: * Social economics: The need to build houses results in having too many houses to build and to create fewer special houses. Decorations and ornaments were not important. * Constructive economics: The reduction of needing points and areas allows new possibilities. That results in more free forms with the same work. * Stylistic economics: The houses represent universality and objectivity and they are a product of [[art]]. ==Related pages== * [[Arc
