Modular construction refers to a method of building a structure, rather than a description of the finished product. Modular buildings are typically built 60 to 90 percent “off-site” in a three-dimensional form, designed to be constructed at one location, and then erected on site.
The Four Stages of Prefab Construction
- Design approval by the end user and any regulating authorities
- Assembly of module components in a controlled environment
- Transportation of modules to a final destination
- Erection of modular units to form a finished building
Shorter Overall Construction Period
While modules are being constructed in a factory, site work is occurring at the same time, therefore reducing labor, financing and supervision costs.
Unique to prefab construction is the ability to simultaneously construct a building’s floors, walls, ceilings, rafters and roofs. During site-built construction, walls cannot be set until floors are in position, and ceilings and rafters cannot be added until walls are erected. On the other hand, with modern modular methods of construction, walls, floors, ceilings and rafters are all built at the same time, and then brought together in the same factory to form a building. This process often allows modular construction times half of that of conventional, stick-built construction.
Built With Safety and Quality in Mind
Traditional building techniques, quality manufacturing and third-party administered random inspections, are combined with testing and certification services for quality control and assure that temporary modular buildings are built in strict accordance with appropriate local, state, and national regulations and codes. We would argue that due to the extra durability needed for travel, factory-built buildings are built better than conventional structures.
