What is prefabrication?

Often called "prefab", prefabrication refers to a construction workflow where assemblies are produced in a manufacturing facility and transported to be assembled on site.

Prefabrication is a growing practice. As integrated delivery becomes more accurate, more complex assemblies can be prefabricated off-site, reducing on-site coordination complexity. This is already common in healthcare, hospitality, and residential.

One common prefab use case that's easy to spot is parking structures. You can spot the unitized elements that lock together to form a variety of different levels and shapes.
