What is factory prefabrication?
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located.
What does prefab mean in construction?
Any component of a building that is manufactured in a factory before arrival and installation at the building site is prefabricated — or ‘prefab’ for short. Modular construction is a specific type of prefab construction. A building could be made entirely of prefabricated components, such as: • Roof trusses.
What is fabricated construction?
Prefabricated construction is the practice of assembling a variety of components of a structure at a manufacturing site and transporting those sub-assemblies to the location of the construction jobsite.
What is the benefit of prefab construction?
The Pros of Prefab This is a controlled, safe environment which allows owners to streamline the construction process and cut down on waste. This makes prefab cost effective. In many cases, prefab also reduces environmental impact. It can lessen air, water, and noise pollution caused by a construction project.
What does prefab mean?
Prefab is short for “prefabricated,” which means “made beforehand,” and not “before fabulous.” Prefab things are made in sections that can be easily shipped and put together to form a finished product. Some buildings and houses are prefab. Prefab can be used as a noun or adjective.
Is modular or prefab better?
Perhaps the largest difference between prefab homes and manufactured homes is the quality of the final product. Modular homes are built with factory precision using 25% more material on average than either site-built or manufactured homes.

What is prefabricated formwork?
Prefab forms are settled in any combination, horizontally and vertically to different types of wall heights. On high walls, one side of form is built up and ties are arranged, then the close-out side is built up at the time of being arranged. Thus the concrete drop is reduced and efficient vibration is maintained.
What are the disadvantages of prefabricated?
Disadvantages
- Leakage occurs in joints in prefabricated parts.
- For huge prefabricated parts, transportation costs can be high.
- To ensure affordability through prefabrication, increased production volume is required.
- Initial costs for construction are higher.
- The initial production of designs is time-consuming.
What does the term prefabrication mean in construction?
The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. The term prefabrication also applies to the manufacturing of things other than structures at a fixed site.
Which is the oldest example of prefabrication in the world?
Prefabrication has been used since ancient times. For example, it is claimed that the world’s oldest known engineered roadway, the Sweet Track constructed in England around 3800 BC, employed prefabricated timber sections brought to the site rather than assembled on-site.
How is prefabrication used in the aerospace industry?
Prefabrication has become widely used in the assembly of aircraft and spacecraft, with components such as wings and fuselage sections often being manufactured in different countries or states from the final assembly site. However, this is sometimes for political rather than commercial reasons, such as for Airbus .
Is the prefab construction growing in the US?
Although prefab construction is still growing slowing in the United States (currently at about 5% of all new homes built), it is gaining traction here and is a major form of construction in other countries around the world.
