Using prefabrication materials, or “prefab”, dramatically speeds up construction time, lowers material costs and increases quality assurance.
Prefab means any area of prefabricated house that has been assembled offsite in a factory or manufacturing facility and transported in complete or sub-assemblies on the construction site. It is actually a broad term and describes 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 could be used in conjunction with each other, independently or with traditional construction methods.
2D prefab is made up of pre-cut, pre-sized, pre-moulded or pre-shaped components which are assembled or set up on steel workshop. They generally arrive as flat-packed panels or non-volumetric systems, ready for assembly. They will often make up the building envelope, stair cores, internal load bearing walls or lighter partitions. They may be 98dexppky or closed panel systems, precast concrete panels or another panel types. 2D prefab is much easier to move, lends itself to mass customisation and possesses infinite construction options, combined with speed of assembly.
3D prefab systems are three-dimensional structural units which are combined at site along with other units or systems, or might comprise an entire small building. They include pods, that happen to be generally not structural modules, such as bathroom or kitchen pods. They can be a fast way to build, as they possibly can be manufactured concurrent with site preparation, and will arrive on location almost complete. 3D prefab systems could be joined together to produce larger spaces plus they are increasingly demonstrating their ability to go prefabricated homes. The weather of 3D prefab might be structural elements, architectural elements or services elements, or they can be a hybrid of such.
