Using prefabrication materials, or “prefab”, dramatically accelerates construction time, lowers material costs and increases quality assurance.
Prefab describes any area of prefabricated house that has been assembled offsite in a factory or manufacturing facility and transported in complete or sub-assemblies for the construction site. It is actually a broad term and identifies a variety of 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 along with the other, on their own 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 frequently arrive as flat-packed panels or non-volumetric systems, ready for assembly. They may form 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 easier to move, lends itself to mass customisation and has infinite construction options, combined with speed of assembly.
3D prefab systems are three-dimensional structural units which 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, such as bathroom or kitchen pods. They can be a rapid method to build, as they possibly can be manufactured concurrent with site preparation, and may arrive on location almost complete. 3D prefab systems can be joined together to create larger spaces and they are increasingly demonstrating remarkable 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.
