Modular buildings are very affordable because of the factory construction of these buildings. They are a very cost effective compared to conventional construction. These units are typically constructed in an enclosed facility, therefore weather is not a factor in the construction time line. Material delivery fees are also out of the equation because an ample amount of material will always be available at the facility, as opposed to being delivered in limited quantities to the job site, nearly eliminating construction delays, and theft of building materials from the site.

Off-Site Construction refers to structures built at a different location than the location of use. Off-Site construction occurs in a manufacturing plant specifically designed for this type of process. Individual modules of the building are constructed in the factory then transported to the site on specially designed trailers. Concrete foundations are dug into the earth allowing the building to be set at grade level eliminating the need for ramps and stairs. Once on site, the building will be installed onto a permanent foundation by fastening it to the ground and to other modules and covering and sealing the seams. These buildings meet all applicable building codes and are indistinguishable from traditional site built construction.

The Off-Site Construction Process reduces project construction time as the buildings are manufactured concurrently with site preparation. In addition, the amount of site disruption is decreased as less work is preformed on site. The process is well suited for projects where local labor is expensive or scarce. As most of the work is preformed in the factory, manufacturing efficiencies can be gained and materials purchased in larger quantities.
