Prefabricated refers to building components that are manufactured off-site and then transported to the construction location for assembly. This method allows for quicker construction times and often reduces waste, as parts are made in a controlled environment. Common examples include prefabricated homes, modular buildings, and precast concrete elements. The prefabrication process can involve various materials, such as wood, metal, or concrete, and is used in both residential and commercial projects. By streamlining production, it can also lead to cost savings and improved quality control, making it an increasingly popular choice in the construction industry.
