Using prefabrication materials, or “prefab”, dramatically speeds up construction time, lowers material costs and increases quality assurance.
Prefab identifies any area of prefab house that has been assembled offsite inside a factory or manufacturing facility and transported in complete or sub-assemblies for the construction site. This is a broad term and identifies 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 person, independently 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 installed on steel workshop. They often arrive as flat-packed panels or non-volumetric systems, ready for assembly. They may constitute the building envelope, stair cores, internal load bearing walls or lighter partitions. They could be 98dexppky or closed panel systems, precast concrete panels or another panel types. 2D prefab is much easier to transport, lends itself to mass customisation and it has infinite construction options, coupled with speed of assembly.
3D prefab systems are three-dimensional structural units that are combined at site with many other units or systems, or might comprise a whole small building. They include pods, that happen to be generally not structural modules, for example bathroom or kitchen pods. They are a rapid approach to build, because they can be manufactured concurrent with site preparation, and can arrive on-site almost complete. 3D prefab systems could be joined together to generate larger spaces and they are generally increasingly demonstrating remarkable ability to look prefab homes. The weather of 3D prefab may be structural elements, architectural elements or services elements, or they could be a hybrid of those.
