Modular buildings may be used for long-term, temporary or permanent facilities, including building crews, universities and schools, civilian and military home, and industrial facilities. Modular buildings are employed in remote and rural areas where conventional construction may not be possible or reasonable, for instance, the Halley VI lodging pods used for a BAS Antarctic expedition.  Other applications have included churches, healthcare centers, retail and sales offices, quick food restaurants and cruise ship building. They can also be used in regions that have weather concerns, such as hurricanes.
Modular buildings and modular homes are prefabricated buildings or houses that contain repeated sections called modules. "Modular" is a construction method that involves assembling sections away from the construction site, then delivering them to the planned site. Setup of these prefabricated sections is completed on site. Prefabricated sections are sometimes placed utilizing a crane. The modules can be set side-by-side, end-to-end, or piled, allowing a variety of styles and configurations.
Permanent modular structures are designed to meet or exceed the exact same building codes and standards as site-built structures and the same architect-specified substances used in conventionally built buildings are traditionally used in modular building projects. PMC can have as many tales as construction codes allow. Unlike relocatable buildings, PMC structures are meant to stay in one place for the whole period of their useful life.
The entire procedure of modular construction puts significance on the design stage. It is vital that there is enough allowance in the design to enable the assembly to take up any"slack" or misalignment of components. The usage of advanced CAD systems, 3D printing and production control systems are important for modular structure to be successful. This is quite unlike onsite construction in which the tradesman can frequently create the part to suit any specific installation.
The buildings are 60 percent to 90% finished offsite at a factory-controlled environment, and transported and constructed in the last building site. This can comprise the whole construction or be parts or subassemblies of larger structures. Oftentimes, modular contractors operate with conventional general contractors to exploit the tools and advantages of each form of construction. Completed modules are hauled to the construction site and assembled by a crane. Placement of the modules may take from several hours to several days.
Building is offsite, with lean manufacturing techniques to prefabricate solitary or multi-story buildings in deliverable module sections. Permanent Modular Construction (PMC) buildings are produced in a controlled environment and can be constructed of wood, steel, or concrete. Modular components are generally constructed indoors on assembly lines. Modules' construction may take as few as ten days but more often a few months.
Modular buildings, also called prefabricated homes or precision built houses, are built to equal or higher standards as on-site stick-built houses. The construction way is known as permanent modular structure.
Substance for pole built and modular houses will be the same. First, modular houses do not have axles or a metallic framework, meaning they are typically transported on flat-bed trucks. Modular buildings have to conform to all applicable local building codes, while doublewides and mobile homes have metal under framing. Doublewides and mobile homes made in the United States are required to conform to national codes governed by U.S. Department of Housing and Urban Development.
