Abstract Prefabricated buildings and structures are mountedfromuniformprefabricatedthreedimensionalunits, providing strength, preset thermal properties of structures, dynamic stability, and immutability of geometric dimensions of the prefabricated elements during their manufacture, transportation, and installation in special and difficult conditions. Prefabrication has been widely regarded as a sustainable construction method in terms of its impact on environmental protection. One important aspect of this perspective is the influence of prefabrication on construction wastereductionandthesubsequentwastehandlingactivities, including wastesorting,reuse,recycle,anddisposal.Thereare a couple of different popular forms of prefab with different benefits to offer. Depending on your specific construction project, you may want to consider implementing some of the options. We’ve pulled together information about the different kinds of prefab as well as the benefits of using this strategy in order to help you decide. In this project the replacement of non structural component with prefabrication element is proposed. The cost benefit analysis will be studied including prefabrication element in conventional building.

1.1 Prefabrication

Prefabricatedconstruction,sometimesknownas"prefab,"is aprominentbuildingstyle.Thistechniqueemploysoff site components manufactured in such a factory, which could then be transferred and assembled on site to form a building. There are many prominent types of prefab that eachhaveitsownsetofadvantages.Imaywishtoexplore usinganyofthesechoicesdependonyouruniquebuilding project. To assist you with making your decision, we've statistics demonstrate on the many types of prefab or the advantagesofemployingthistechnique.
