Using prefabrication materials, or “prefab”, dramatically accelerates construction time, lowers material costs and increases quality assurance.
Prefab describes any part of prefabricated house which has been assembled offsite in the factory or manufacturing facility and transported in complete or sub-assemblies to the construction site. It is a broad term and means many 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 together with one another, on their own or with traditional construction methods.
2D prefab consists of pre-cut, pre-sized, pre-moulded or pre-shaped components that happen to be assembled or attached to 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 might be 98dexppky or closed panel systems, precast concrete panels or any other panel types. 2D prefab is much easier to transport, lends itself to mass customisation and it has infinite construction options, coupled with speed of assembly.
3D prefab systems are three-dimensional structural units that happen to be combined at site with other units or systems, or might comprise a full small building. They include pods, that are generally not structural modules, such as bathroom or kitchen pods. They are a fast approach to build, as they can be manufactured concurrent with site preparation, and can arrive on location almost complete. 3D prefab systems could be joined together to produce larger spaces and they are generally increasingly demonstrating remarkable ability to travel prefabricated homes. The weather of 3D prefab may be structural elements, architectural elements or services elements, or they can be a hybrid of those.
