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 on the construction site. It is actually 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 are often used together with one another, alone or with traditional construction methods.
2D prefab consists of pre-cut, pre-sized, pre-moulded or pre-shaped components that are assembled or placed on steel warehouse. They generally arrive as flat-packed panels or non-volumetric systems, ready for assembly. They may form 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 much easier to move, lends itself to mass customisation and possesses infinite construction options, put together with speed of assembly.
3D prefab systems are three-dimensional structural units that are combined at site with some other units or systems, or might comprise an entire small building. They include pods, that happen to be generally not structural modules, for example bathroom or kitchen pods. They can be a rapid method to build, as they can be manufactured concurrent with site preparation, and will arrive on location almost complete. 3D prefab systems might be joined together to generate larger spaces and they are generally increasingly demonstrating their ability to visit prefab homes. The weather of 3D prefab could be structural elements, architectural elements or services elements, or they might be a hybrid of such.
