Prefabrication Methodology for Building Construction

Abstract

Prefabricated building construction systems have been widely adopted not only in public houses but also in private building projects. Prefabrication is today’s need. It gives opportunities for good architecture, together with the increasing use of standardization, and mechanization that has brought a substantial change in the development of the construction industry worldwide over the last few decades. The drastic increase in the application of this technology in building projects in the recent years does regain certain momentum in this left-behind area. Prefabrication technique for residential buildings uses a system of precast units for columns, beams, roofs, and walls. Precast RCC planks and partially precast RC joists are considered for flooring/roofing systems. Prefabricated columns with a specific configuration, beams, and staircase units are considered. The extensive use of prefabrication also contributes to sustainable development by using cleaner and more resource-saving production process. Prefabrication building methodology for low-cost housing and its selection criteria is mentioned. Also significant benefits of prefabricated element comparing with on-building site, and their various elements, advantages, disadvantages, limitations, and economical design aspects are discussed.
