Using prefabrication materials, or “prefab”, dramatically speeds up construction time, lowers material costs and increases quality assurance.
Prefab identifies any area of prefab house which has been assembled offsite within a factory or manufacturing facility and transported in complete or sub-assemblies to 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 are often used jointly with each other, independently or with traditional construction methods.
2D prefab is composed of pre-cut, pre-sized, pre-moulded or pre-shaped components that happen to be 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 may be 98dexppky or closed panel systems, precast concrete panels or other panel types. 2D prefab is easier to move, lends itself to mass customisation and contains infinite construction options, along 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 a complete small building. They include pods, which can be generally not structural modules, including bathroom or kitchen pods. They may be a fast method to build, as they are able be manufactured concurrent with site preparation, and might arrive on site almost complete. 3D prefab systems might be joined together to generate larger spaces plus they are increasingly demonstrating remarkable ability to visit light steel villa. The weather of 3D prefab could be structural elements, architectural elements or services elements, or they can be a hybrid of those.
