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 within a factory or manufacturing facility and transported in complete or sub-assemblies on 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 could be used along with each other, by themselves or with traditional construction methods.
2D prefab is made up of pre-cut, pre-sized, pre-moulded or pre-shaped components that happen to be assembled or set up on steel structure warehouse. They generally 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 might be 98dexppky or closed panel systems, precast concrete panels or some other panel types. 2D prefab is simpler to move, lends itself to mass customisation and contains 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 a full small building. They include pods, which are generally not structural modules, including bathroom or kitchen pods. They may be a speedy way to build, as they can be manufactured concurrent with site preparation, and might arrive on-site almost complete. 3D prefab systems might be joined together to produce larger spaces and they are generally increasingly demonstrating their ability to go prefab homes. The weather of 3D prefab may be structural elements, architectural elements or services elements, or they could be a hybrid of the.
