Prefabrication Methods for Lean Delivery of Construction Projects

The construction industry has been receiving severe criticism over its inability to improve productivity associated with project delivery as compared to the manufacturing industries. The construction projects continue to struggle with the problems of delay, cost overruns, and litigations. Lean construction philosophy evolved from Toyota’s Production Systems (TPS) has gathered significant attention in recent years and has been proven to be successful in minimizing the inefficiencies and wastages at projects and improving the project delivery. The prefabricated method of construction has been found to fasten the delivery of projects and achieve the principles of pull production, Just in Time (JIT) and minimize wastages. The development of prefabricated structures in the construction industry has shown the potential to drastically improve the construction environment, productivity and quality. The present paper discusses a part of the work carried out to investigate the cost–benefit analysis of the prefabrication methodology for the construction of residential projects using the prefabrication method over traditional projects. The study aims to introduce the methods and techniques of prefabrication for building projects and how it contributes to sustainable lean delivery of building construction projects.
