The construction boom in India is developing at a fast rate of growth. It provides wide opportunity in India for a new entrant in prefab sector. At present precast concrete buildings are the advanced construction techniques available over worldwide. Being its wide applicability, the total precast concrete buildings systems are becoming a popular choice for many construction. Precast concrete available in many shape, sizes, including structural elements and unreinforced pieces. The prefab industry is the backbone for the development of new ideas in construction business of any country; Factory buildings, residential buildings and the industrial township are needed practically by all the sectors, either to support the manufacturing or services of any industry.

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. A modular structure however, is not a mobile structure; it is simply a structure that is built off-site as opposed to on-site. These structures are often called factory-built structures, system-built or pre-fab. structures. Modular and manufactured structures however, are not the same. Manufactured buildings are not placed on permanent foundations. Manufactured homes, sometimes referred to as mobile homes can be moved from one location to another. Prefabrication has been used extensively and widely for many years around the world. Pre-assembly, prefabrication, modularization, system building and industrialized buildings are the terms which have been frequently used to describe that the manufacture of building components are constructed either on-site or off-site in a factory covering manufactured, modular and pre-cut or pre-engineered systems. Although the terms, are often interchangeably used, their precise definitions depend heavily on the users’ experience and understanding, which vary from country to country.

 Prefabrication is preferred with special emphasis on the building components are made off-site in a factory. Off-site fabrication is a topic of international interest and provides an effective construction technique in term s of quality, time, cost, function, productivity and safety. It is adopted worldwide as the ideal means of producing an immense array of elements from structural members, cladding units, and bathrooms to fully-finished modular buildings.

Architects are incorporating modern designs into the prefabricated houses of today. Prefab housing should no longer be compared to a mobile home in terms of appearance, but to that of a complex modernist design.

There has also been an increase in the use of "green" materials in the construction of these prefab houses. Consumers can easily select between different environmentally friendly finishes and wall systems. Since these homes are built in parts, it is easy for a home owner to add additional rooms or even solar panels to the roofs.

The main objective of this paper is to Investigate the current level of utilization of prefabrication technology in the building sector of the construction industry,examine the advantages and disadvantages of prefabrication technology in the building industry examine the advantages and challenges of conventional building practices in the current industry and formulate construction techniques that will integrate prefabrication in the current conventional building practices.
