Using prefabrication materials, or “prefab”, dramatically speeds up construction time, lowers material costs and increases quality assurance.
Prefab describes any area of prefab house which has been assembled offsite in a factory or manufacturing facility and transported in complete or sub-assemblies on the construction site. This is a broad term and refers to several 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 jointly with the other person, on their own or with traditional construction methods.
2D prefab is made up of pre-cut, pre-sized, pre-moulded or pre-shaped components that are assembled or installed on steel structure warehouse. They often arrive as flat-packed panels or non-volumetric systems, ready for assembly. They could form the building envelope, stair cores, internal load bearing walls or lighter partitions. They may be 98dexppky or closed panel systems, precast concrete panels or any other panel types. 2D prefab is simpler to transport, lends itself to mass customisation and possesses infinite construction options, coupled with speed of assembly.
3D prefab systems are three-dimensional structural units which are combined at site with some other units or systems, or might comprise an entire small building. They include pods, which can be generally not structural modules, including bathroom or kitchen pods. They may be a speedy strategy to build, as they can be manufactured concurrent with site preparation, and may arrive on-site almost complete. 3D prefab systems can be joined together to make larger spaces and they are increasingly demonstrating remarkable ability to go prefab homes. The elements of 3D prefab could be structural elements, architectural elements or services elements, or they might be a hybrid of these.
