Offsite construction is typically used on projects with repetitive floorplans or layouts in their design such as apartment buildings, hotels, hospitals, dormitories, prisons, and schools. Offsite is performed in a controlled environment and it works similar to an auto manufacturing plant. At each station, workers have all the tools and materials to consistently perform their task, whether that be constructing a wall frame or installing electrical wiring. This assembly plant method of construction reduces waste and allows workers to be more productive.

Offsite construction typically comes in two forms: modular and prefabricated. With modular construction, entire rooms can be built complete with MEP, finishes, and fixtures already installed. They can be rooms as small as bathrooms or modules can be fitted together onsite to create larger spaces like apartment units. The modular units are transported to the construction site and then inserted and attached to the structural frame.

With prefabricated construction, building components are built offsite and then assembled or installed once they have been transported to the construction site. Prefabricated building components cover everything from framing, internal and external wall panels, door and window assemblies, floor systems, and multi-trade racks, which are panels with all the ductwork, wiring, and plumbing packaged together.
