Using prefabrication materials, or “prefab”, dramatically speeds up construction time, lowers material costs and increases quality assurance.
Prefab identifies any part of prefabricated house which has been assembled offsite in the factory or manufacturing facility and transported in complete or sub-assemblies to the construction site. It is a broad term and refers to a number of different systems or processes, including structural, architectural and services elements.
Prefabaus – the peak body for Australia’s off-site construction industry – breaks up prefab into two main families, 2D prefab and 3D prefab. They may be used together with the other, on their own or with traditional construction methods.
2D prefab is comprised of pre-cut, pre-sized, pre-moulded or pre-shaped components that happen to be assembled or attached to steel structure warehouse. They often arrive as flat-packed panels or non-volumetric systems, ready for assembly. They might make up the building envelope, stair cores, internal load bearing walls or lighter partitions. They could be 98dexppky or closed panel systems, precast concrete panels or other panel types. 2D prefab is simpler to move, lends itself to mass customisation and it has infinite construction options, combined with speed of assembly.
3D prefab systems are three-dimensional structural units which can be combined at site with many other units or systems, or might comprise an entire small building. They include pods, which can be generally not structural modules, such as bathroom or kitchen pods. These are a rapid approach to build, because they can be manufactured concurrent with site preparation, and might arrive at your location almost complete. 3D prefab systems might be joined together to make larger spaces and are generally increasingly demonstrating their ability to go prefabricated homes. The elements of 3D prefab can be structural elements, architectural elements or services elements, or they might be a hybrid of such.
