Using prefabrication materials, or “prefab”, dramatically accelerates construction time, lowers material costs and increases quality assurance.
Prefab identifies any area of prefab house that has been assembled offsite in the factory or manufacturing facility and transported in complete or sub-assemblies to the construction site. This is 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 may be used jointly with one another, 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 placed on steel workshop. They often times arrive as flat-packed panels or non-volumetric systems, ready for assembly. They may 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 any other panel types. 2D prefab is a lot easier to transport, lends itself to mass customisation and contains infinite construction options, along with speed of assembly.
3D prefab systems are three-dimensional structural units which can be combined at site with 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 can be a rapid way to build, as they can be manufactured concurrent with site preparation, and might arrive on-site almost complete. 3D prefab systems can be joined together to create larger spaces and they are generally increasingly demonstrating their ability to travel prefab homes. The elements of 3D prefab might be structural elements, architectural elements or services elements, or they might be a hybrid of those.
