Construction of prefabricated buildings on sites

Prefabrication is the process of making buildings, or components of buildings, in a different location than the job site itself. Construction companies will transport the completed unit to the final site, where they will also complete the setup and handover buildings to their new owners. This process eliminates the need for traditionally sourced construction materials because off-site assembled parts result in less waste. As the raw materials are built off-site and shipped partially assembled, prefabrication reduces the cost of labor and the cost of materials.

There is controversy regarding prefabrication because, in the past, it was a low-mass development method. Prefabrication is getting more and more relevant in the construction industry, but more significant in commercial construction. However, civil engineers use prefabrication the most because mass amounts of pre-assembled concrete and steel sections are made then transported to sites.
