What is a Prefabrication?
Prefab is a way to create innovative high-quality buildings on time and within budget. Prefab is short for prefabrication. It refers to any part of a building that is made away from the final building site, which is why it can also be referred to as offsite construction or manufacture (OSM).
Prebuilt construction is first and foremost a higher quality solution as parts are built in a controlled environment, not on an exposed construction site. Secondly it is an efficient and quickly assembled solution that saves time. Thirdly it is a cost-effective solution as ‘saving time is the fastest way to save money’.
Prefab applies to all building types from homes to commercial to infrastructure. As an example, your home probably has pre-nailed roof trusses and wall frames. Your bach might have started as a transportable building. Your workplace may use precast concrete elements.
Prefab is a complimentary system to traditional construction and has been used since pre-colonial times when raupo was bundled into wall panels at the edges of wetlands. Prefab is not a new concept.
Prefab comes in all shapes and sizes, from small components such as pre-nailed wall frames, to panels, larger modules (3-D volumes) or even complete buildings. Hybrid prefab is a mixture of several systems, or prefab with traditional construction.
Prefab can be made of any materials, timber, concrete, metals, plastics, or any combination.
