Prefabrication is a construction method where building components are manufactured off-site in a factory setting before being transported to the construction site. This process allows for greater precision and efficiency, as parts can be produced in a controlled environment, reducing waste and construction time. Once the prefabricated components arrive at the site, they are assembled quickly, often leading to faster project completion. This technique is commonly used in various types of construction, including residential homes and commercial buildings, and can involve materials like wood, steel, and concrete.
