What is Prefabricated Construction?

Prefabrication, also known as prefabricated construction is the process of producing various structural components at a factory or manufacturing facility off-site before bringing the entire set of components to the construction site for the assembly of the project. All of this is known as off-site construction. Numerous issues connected to crowded, hectic, and congested urban environments on construction sites are resolved by prefabricated construction. Transporting supplies and equipment across the work site and inside the site’s boundaries might be quite difficult, which would raise the cost and lengthen the project’s schedule. Prefabrication is the ideal solution for all these issues. Offsite construction offers better options for off-site design an

Prefabricated materials are durable, efficient from a budgetary standpoint, and sustainable. Construction items and materials that are prefabricated are of higher quality than those that are manufactured on-site. Great design, high-performance actions, and quality-controlled production processes are all features of prefabricated construction. Manufacturing and delivery to construction sites are the two key processes in prefab construction. Prefabricated materials are produced in off-site factories or prefab construction units in the first stage, and they are then used to erect the structure on-site in the second stage.

Benefits of using Prefabricated Construction

Following are the benefits of using Prefabricated Construction:

  • Prefabricated construction of structures with repetitive use of a single type of building element most frequently uses prefabricated building materials like concrete and steel pieces.
  • Utilising prefab buildings eliminates the need to pump wet over layouts on crowded construction sites and bring the concrete mix to the site.
  • Utilising prefabricated materials lowers the costs and hazards associated with on-site cutting and welding of steel parts for various purposes.
  • Because of the constant application of a standard procedure, factory-made prefabricated components not only offer greater quality assurance but also constant temperature for production and activity streamlining, both of which increase workplace safety.
  • The garbage produced accumulated at a specific location that can be easily handled and properly discarded since prefabricated components are built in specific manufacturing areas to supply materials to single or many organisations.
  • Prefabricated buildings are frequently utilised in housing colonies, apartment complexes, and other structures with recurring patterns of offices, warehouses, and commercial structures.
  • Overproduction of glass and steel occurs in prefabricated construction components for enormous skyscrapers.
  • Compared to the on-site fabrication of bridge components, prefabricated building materials are more affordable. Bridges built using prefabrication save time and have a minimal environmental impact.
  • The prefabricated building materials accumulated under 

Comprehensive Prefabrication System

Prefabricated materials include several material systems in addition to concrete and steel components. Prefabrication systems that are frequently used include the following: 

  • Sandwich Panels: These are made of thin facings of materials adhered firmly to the two sides of an insulating core material. Foam, paper, textiles, rubber, etc. can be utilised as face materials, and concrete, plywood, stainless steel, etc. can be used as insulating materials.
  • Panelized Wood Framing: These systems consist of lengthy frames made of laminated wood that is covered in plywood or some other type of roof deck. Typically, these prefabricated components are used to build roofs.
  • Concrete Systems: Using concrete components in the prefabricated building offers more adaptability and time savings. Despite their weight, concrete components are durable in use and enhance the structure’s elegance.
  • Steel Framing: Buildings can be constructed using a steel frame which is a material that is strong and long-lasting.
  • Timber Framing: Timber framing: Although not very prevalent in India, timber framing panels are used as prefabricated components for the construction of timber dwellings.
  • Versatile Systems: The whole construction of these systems consists of off-site factories’ prefabricated building components. To build the structure, the parts are simply linked after being transported to the construction site.   


Prefabricated buildings, also known as prefabs, are structures containing parts (such as walls, roofs, and floors) made at a factory or manufacturing facility. Before being delivered to the site, these components can be partially or totally constructed at a factory.

Since production through a production line is more controlled, prefabrication is more efficient than traditional on-site construction.

Prefabricated buildings have a number of advantages, including quicker on-site construction, less impact from uncontrollable elements, improved quality and uniformity, economic effectiveness, reusability, less waste of raw materials, and decrease safety risks.

Prefabricated structures can be categorised based on their level of construction. Component, panel, element, hybrid, and fully assembled buildings are the various construction kinds.

  • The cost of prefabricated buildings is comparable to or higher than that of conventional buildings. The quicker they can be installed and used, the more money may be saved from using them which boosts the ROI.
