Prefabrication (Prefab)
The practice of assembling building components in a factory before transporting them to the construction site.
Prefabrication is the broad term for any construction process where components are manufactured in a controlled factory setting before being delivered to the building site. It encompasses volumetric modular, panelized, and component-level prefab. Benefits include reduced waste (up to 90% less), better quality control, improved worker safety, and faster project delivery.
