Using prefabrication materials, or “prefab”, dramatically speeds up construction time, lowers material costs and increases quality assurance.
Prefab identifies any section of prefab house that has been assembled offsite inside a factory or manufacturing facility and transported in complete or sub-assemblies on the construction site. It really is a broad term and identifies 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 are often used in conjunction with one another, on their own or with traditional construction methods.
2D prefab is comprised of pre-cut, pre-sized, pre-moulded or pre-shaped components which are assembled or attached to steel structure warehouse. They frequently 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 could be 98dexppky or closed panel systems, precast concrete panels or any other panel types. 2D prefab is a lot easier 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 that are combined at site along with other units or systems, or might comprise a full small building. They include pods, that happen to be generally not structural modules, for example bathroom or kitchen pods. They may be a fast approach to build, as they possibly can be manufactured concurrent with site preparation, and will arrive on-site almost complete. 3D prefab systems can be joined together to produce larger spaces plus they are increasingly demonstrating their ability to go prefab homes. The weather of 3D prefab could be structural elements, architectural elements or services elements, or they may be a hybrid of these.
