A prefabricated building, informally a prefab, is a building that is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on-site to form the complete building. Various materials were combined to create a part of the installation process. [1]
An example from house-building illustrates the process of prefabrication. The conventional method of building a house is to transport bricks , timber , cement , sand , steel and construction aggregate , etc. to the site, and to construct the house on site from these materials.
Traditionally, construction has made use of manual labor such as tradesmen and subcontractors for tasks such as the installation of prefabricated elements. [6] In the industrialization phase, construction uses manufacturing processes and technology to perform off-site prefabrication, assembling building components off-site rather than at the point of installation.
Construction is offsite, using lean manufacturing techniques to prefabricate single or multi-story buildings in deliverable module sections. Often, modules are based around standard 20 foot containers, using the same dimensions, structures, building and stacking/placing techniques, but with smooth (instead of corrugated) walls, glossy white paint, and provisions for windows, power, potable ...
The introduction of modular prefabricated units is not only possible in low-rise construction but also in multi-story and high-rise construction. [1] To save the most time and money and maximize the efficiency of the modular construction process, it must be implemented at the beginning of the design-build process.
Modern methods of construction (MMC) is a term used mainly in the UK construction industry to refer to "smart construction" processes designed to improve upon traditional design and construction approaches by focusing on (among other things) component and process standardisation, design for manufacture and assembly (), prefabrication, preassembly, off-site manufacture (including modular ...
An example of a completed panelized home in Lake Whatcom, United States. Currently, the prefabricated housing industry is divided by methodology of construction. Panelized, Modular, and Manufactured home design make up the majority of contemporary firms, with considerable overlap between the construction methods. [8]
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 ...
