Building envelopes are perhaps the most influencing players on assuring indoor comfort conditions, in alliance with their impact on the sustainability and energy-efficiency of the building during operation. However, given the multitude of commercial solutions available on the market and the use of different criteria and inconsistent semantics among the existing categorization/classification systems of construction objects, there is still a need for uniformization of the many regarding the main Prefabricated Enclosure Wall Panel Systems (PEWPS) for building applications.In such context, this paper firstly explores the distinct categories of off-site Modern Methods of Construction (MMC), and how can they be classified. Secondly, focus will be given to panelized systems, where the classification of PEWPS is thoroughly investigated, the size and complexity of individual components have a significant impact on the ease of installation of a system. Larger prefabricated panels are typically heavier and bulkier, making transportation and erection more difficult. Smaller panels are made up of more and smaller a component, which increases the amount of on-site construction labor. In this paper, costs have been reduced by Stainless Steel 316This thesis has tried to devise a solution which balances the manufacture’s need to make a repetitive solution many times with an industry that generally designs a specific solution for each enclosure system.Customer-caused losses include inefficiencies such as frequent design and specificationmodifications, as well as delays due to missing approvals. The Lean Construction Institute hasaided in the transformation of the construction culture through the application of agile and leanphilosophies, principles, and techniques. This paper has highlighted the non-conformities at the organization and the NCR to curtail this to reduce costs and internal quality.
