Modular buildings may be used for long-term, temporary or permanent facilities, including construction crews, schools and classrooms, civilian and military housing, and industrial facilities. Modular buildings are used in remote and rural areas where conventional construction may not be possible or reasonable, for example, the Halley VI lodging pods used for a BAS Antarctic expedition.  Other uses have included churches, health care centers, sales and retail offices, quick food restaurants and cruise boat building. They can also be utilised in areas that have weather issues, such as hurricanes.
Material for stick built and modular homes are the same. To begin with, modular houses don't have axles or a metal framework, meaning they are typically transported on flat-bed trucks. Modular buildings must conform to all applicable local building codes, while doublewides and mobile homes have metal beneath framing. Doublewides and mobile houses made in the USA need to conform to national codes regulated by U.S. Department of Housing and Urban Development.
The buildings are 60 percent to 90% finished offsite at a factory-controlled environment, and transported and assembled at the last construction website. This can include the entire construction or be components or subassemblies of larger structures. In many cases, modular builders operate with traditional general contractors to exploit the resources and advantages of each form of construction. Finished modules are transported to the construction site and constructed by a crane. Placement of the modules can take from a few hours to several days.
Construction is offsite, using lean production techniques to prefabricate single or multi-story structures in deliverable module sections. Modular components are typically constructed inside on assembly lines. Modules' construction may take as little as ten days but more often a few weeks.
Permanent modular buildings are built to meet or exceed the same building codes and standards as site-built structures and also the exact same architect-specified substances utilized in conventionally built buildings are traditionally used in modular construction jobs. PMC can have as many stories as construction codes allow. Unlike relocatable buildings, PMC structures are intended to remain in 1 place for the duration of their life.
The full process of modular building places significance on the plan stage. It is vital that there's sufficient allowance at the design to enable the assembly to take any"idle" or misalignment of elements. This is very unlike on-site construction where the tradesman can often create the part to match any specific installation.
Modular buildings and modular houses are prefabricated buildings or houses which consist of repeated sections called modules. "Modular" is a construction method that entails constructing sections away from the building site, then delivering them to the planned website. Installation of these prefabricated sections is completed on site. Prefabricated sections are occasionally placed using a crane. The modules can be set side-by-side, end-to-end, or piled, allowing a variety of configurations and styles.
Modular buildings, also called prefabricated homes or precision built houses, are developed to equivalent or higher standards as on-site stick-built homes. The construction method is known as permanent modular construction.
