"PRE-ENGINEERED (OR) PREFABRICATED CONSTRUCTION"

                        'Prefabrication is the Practice of assembling components of a structure in a factory or other manufacturing site ,and transporting complete .Assemblies or sun-assembiles to the construction site.where the structure to be located'.

                             'The term prefabrication also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location and the section is supplied assembled andread to fit'.

PROCESS OF PREFABRICATION :

                         ' An example from house-building illustrates the process of prefabrication.The conventional method of building a house is to transport brick timber,sand, cement, steel, etc..to the site and to construct the house on site from these materials.In prefabricated construction,only foundations are constructed in the site.while the section are like walls,roof, floors are prefabricated assembled from the factory and after transport to the site Lift & place by the help of cranes'.

                            

HISTORY OF PREFABRICATION CONSTRUCTION : 

                        'Prefabrication has been used since ancient times. For example it is claimed that the world's oldest known engineered roadway the Sweet track constructed in England around 3800 BC employed Prefabricated timber section brought to the site or rather than assembled on the site'.

                                                                                                                                               'This method was widely used in the construction of Prefabricated  housing from the 20th century'.

CURRENT USES OF PREFABRICATION :

                                          ' The most widely used from of Prefabrication in building and civil engineering is the use of Prefabricated concrete and Prefabricated steel section in structures.Prefabrication techniques are used in the construction of apartment, blocks,and housing development.Detached houses,cottages ,log cabin,ect...are also sold by Prefabrication elements.Prefabrication saves engineering time on the construction site in civil engineering Prefabrication is widely used for assembly for aircraft and spacecraft with components'.
