When was the last time you saw a big bridge being constructed wholly on-site? Maybe long ago. The tedious, often annoying, method of construction has now almost been completely replaced by prefabricated structures. The need to do it quick, sleek and without taking much space has forced people to look for alternative mode of constructions. Prefabrication is one of them. But the use of prefabricated structures in not limited to big bridges only. Nowadays they are being used in small constructions.
Prefabrication is a process in which a big structure is disunited into smaller ones and each unit is manufactured at different locations. Once designed they are transported, either wholly assembled or partially assembled, to its destination.
