Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or subassemblies to the construction site where the structure is to be located. The term is used to distinguish this process form the more conventional construction practices of transporting the basic materials to the construction site where all assembly is carried out.
Advantages
Prefabricated building are very affordable because of eh factory construction of these buildings. They are very cost effective compared to conventional construction. These units are typically constructed in an enclosed facility; therefore weather is not a factor in the construction time line. Material delivery fees are also out of equation because an ample amount of materials will always be available at the facility, as opposed to being delivered in limited quantities to the job site, nearly eliminating construction delays, and theft of building materials from the site.
Such dwellings are often priced lower than their site built counterparts and are typically more cost effective to builders and consumers, these new homes can constructed in less time than it takes to build a home “onsite”. The following reasons for the typically lower cost/price of these dwellings.
Standards and zoning Considerations
Typically, modular dwellings are built to local or state or council code, so dwellings built in a given manufacturing facility will have differing constructions standards depending on the final destinations of the modules. Steel and /or wood frames are common options for building a modular home. Modular homes designs can be customized for local zoning codes.
Save Builders / Owners Capital
Because large pieces of the structural come from a factory and are designed for quick and easy assembly on-site, builders reduce on-site costs, such s labor, worker’s compensation, and insurance. Assembly- line production also allows prefab manufactures greater quality control. Typically prefab housing products include roof trusses, wall frames and floor. Many builders also use pre-made wall panels complete with insulation, plumbing, wiring, ventilation system and doors.
