Faster construction: Prefabricated or modular construction can be completed much faster than traditional construction methods, as much of the work is done offsite in a controlled environment.
Prefab is any construction process that does not take place on-site, while modular construction specifically consists of the building of repeated sections called modules being built in the factory and then assembled on site.
Prefabrication is a broad category of construction, which seeks to maximize efficiencies in construction by moving portions of the process off-site. Modularization is the most efficient class of prefabrication, manufacturing entire building units inside a facility.
Prefabrication starts with building components created and assembled offsite in a factory or other manufacturing site. Complete assemblies or sub-assemblies are then transported to the construction site. Modular buildings are constructed in separate box-like modules which are then secured together on-site.
The terms prefabrication and modular construction are often used interchangeably. Prefabrication refers to the manufacturing of construction elements away from
Offsite construction refers to the manufacturing, planning, design, fabrication, and assembly of building elements at a location other than their final installed location to support the rapid speed of, and efficient construction of a permanent structure.
Such building elements may be prefabricated offsite in a different location and transported to the site or prefabricated on the construction site and then transported to their final location.
Offsite construction is characterized by an integrated planning and supply chain optimization strategy.
Offsite manufacturing (OSM), offsite production (OSP) and offsite fabrication (OSF) are used when referring primarily to the factory work proper.
Manufacturing of components before assembly
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located.
Some researchers refer it to “various materials joined together to form a component of the final installation procedure“.
