Permanent modular buildings are built to meet or exceed the exact same construction standards and codes as site-built structures and also the exact same architect-specified materials used in conventionally built buildings are employed in modular construction jobs. PMC may have as many stories as construction codes allow. Unlike relocatable buildings, PMC structures are meant to remain in one place for the whole period of their life.
The buildings are 60 percent to 90% finished offsite in a factory-controlled surroundings, and transported and assembled at the last building site. This can comprise the whole building or be parts or subassemblies of bigger structures. Oftentimes, modular contractors operate with traditional general contractors to exploit the resources and advantages of each form of construction. Finished modules are hauled to the building site and assembled by means of a crane. Positioning of the modules may take from a few hours to several days.
Building is offsite, using lean manufacturing techniques to prefabricate single or multi-story structures in deliverable module sections. Permanent Modular Construction (PMC) buildings are produced in a controlled environment and can be constructed of timber, steel, or concrete. Modular components are typically constructed indoors on assembly lines. Modules' structure may take as little as ten days but more often a few months. PMC modules can be incorporated into website constructed projects or stand alone and may be delivered with MEP, fixtures and interior finishes.
Material for pole built and modular houses are the same. Modular homes are not doublewides or mobile homes. To begin with, 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 relevant regional building codes, whereas doublewides and mobile homes have metal under framing.
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 employed in rural and remote regions where traditional construction might not be possible or reasonable, by way of instance, the Halley VI lodging pods employed for a BAS Antarctic trip.  Other uses have included churches, health care facilities, sales and retail offices, fast food restaurants and cruise ship construction. They may also be used in areas that have weather issues, like hurricanes.
The entire procedure of modular building puts significance on the plan stage. It is vital that there is enough allowance at the layout to enable the meeting to take any"slack" or misalignment of components. This is quite unlike on-site construction where the tradesman can often make the part to match any specific installation.
Modular buildings and modular houses are prefabricated houses or buildings which contain recurrent sections called modules. "Modular" is a construction method that involves constructing sections from the building site, then delivering them to the intended website. Installation of these prefabricated sections is finished on site. Prefabricated sections are sometimes placed using a crane. The modules can be placed side-by-side, finishing, or piled, allowing a variety of styles and configurations.
Modular buildings, also referred to as prefabricated homes or precision built homes, are built to equivalent or higher standards as on-site stick-built houses. The construction way is known as permanent modular construction.
