Modular building is complete

Modular construction, also known as volumetric, and prefabricated building, refers to a method of building an off-site structure to be delivered for final assembly. Modular, or prefab, buildings are typically built 60 to 90 percent off-site in a three-dimensional form: constructed at one location, and then used by occupants at another.

Modern, custom, multi-story, factory-built buildings with concrete and steel floors, brick exteriors, sheetrock interiors, windows, lighting, computer hook-ups, electrical service, plumbing, heating, air conditioning, and restrooms can include everything you need and can be constructed in half the time of a site-built building.

The Four Stages of Prefab Building

  1. Design approval by the end-user and any regulating authorities
  2. Assembly of module components in a controlled environment
  3. Transportation of modules to a final destination
  4. Erection of modules to form a finished building

Concurrent activities compress overall project schedule:

While modules are being constructed in a factory, site work is occurring at the same time. This allows for earlier building occupancy and contributes to a much shorter overall construction period. This process can often reduce the length of modular construction projects by half of conventional, stick-built construction with the same life expectancy as traditionally built buildings.
