"Prefabricated" refers to building components that are manufactured in a factory setting before being transported to a construction site for assembly. This method allows for greater efficiency, as parts can be produced simultaneously and under controlled conditions, reducing construction time and costs. Common examples of prefabricated structures include modular homes and precast concrete panels. These components are designed to fit together easily, making the construction process quicker and often more sustainable. Prefabrication can also lead to improved quality control, as items are built in a consistent environment rather than exposed to the variables of on-site construction.
