A modular building is a custom-designed structure built in sections called modules. The modules are constructed in an off-site production facility, then delivered to the intended site and set on a foundation as a permanent structure. Construction of the modules, in most cases, is 90% complete prior to shipment. Completion is done on-site after the modules have been set onto the building's foundation and joined together to make a single structure. The modules can be placed side-by-side, end-to-end, or stacked, allowing a wide variety of configurations and styles in the building layout.
Manufacturing Process
The production process begins by constructing the floor system of the module. The floor system is built on a “jig” keeping it square and plumb. Once the floor system is complete the pre-constructed wall panels (also built on a jig) are added. The roof system is now ready to be set in place, thus completing the structure portion of the module.
The electrical wiring and plumbing are inserted into the module both during the general construction of the structure and after the structure is complete. The exterior walls are then insulated and covered with sheathing. Sanding and painting are next and in the final stages of production, items such as custom cabinetry, fixtures, flooring, molding and trim are installed. A final quality assurance inspection is performed to ensure the module is complete.
After passing the final inspection the module is wrapped in a durable plastic to protect it against the elements and loaded onto a carrier in preparation for transporting it to the building site.
