Prefabrication is the assembling of all the components used for construction at the factory and then taking it to the construction site. This is an unconventional practice in some countries as most of them carry basic materials to the construction site and then assemble it there. Hence prefabrication has many advantages. Steel buildings have been there since the time of World War II but the laymen do not have much idea about it. The history of prefabrication can be traced back to 3800 BC. It seems to be an engineer’s word when it is said prefabricated steel buildings. But actually, it is only a predetermined design made with the help of computers that assists in making the specifications for the type of steel to be used and its design specifications. The steel buildings have evolved and have newer components. To handle the whole process of mass production efficiently, a pre-engineered system is developed. Most designs are project specific and hence the pre-engineered system is now becoming redundant. Prefabrication of steel buildings helps to save time as most of it is consumed in the designing aspect and putting it all together. Prefabricating steel sections reduces on-site cutting and welding costs as well as the hazards associated with it.
