Studies on Integration of Lean Construction and Sustainability in Indian Real Estate Projects

Indian Real estate market has grown largely in recent, which has achieved faster growth among the developing global markets. Quick urbanization and increase in income of the public is the prime reason for the demand and growth of Indian real estate. On the other hand multiple issues like incompetence, productivity declination, waste generation, low sales, etc. are bothering Indian Real estate. To hamper these, lean principles have been introduced in the field of construction which had caused a revolution in the manufacturing process and green building practices to reduce its negative ecological footprint with simultaneous creation of more sustainable environment. The value maximization and waste minimization of a project are achieved through lean construction and its techniques will be integrated with the current sustainable construction techniques to diminish the current wastage without comprising the quality of the construction. When used and combined perfectly, the sustainable parameters and lean principles can be aligned to yield better results and counter support the benefits of both. Lean principles to combine with sustainability parameters in cast-in situ construction in Indian context are a challenging task. Independently both lean construction and sustainability in construction have proven results in Indian real estate projects. However, no studies or framework on integrating the cast-in situ construction of have been attempted either for world across or within Indian context. This paper mainly focuses on the small scale real estate projects. The stakeholders or parties of smaller construction projects argue that the implementation of lean construction in their projects will not yield the results and claim to be the best way that they adopt with their experience, which is not really true on field. To prevent this problem, the adoption of sustainability with respect to the environmental, social, and economic terms will further enhance the building value in the construction market. This paper follows an integration procedure (with reference to PMBOK) of lean and sustainability concepts together are the key to the efficient and economic construction in the future. As these require a detailed study of the all the attempts previously made and helps to frame a perfect model which makes it an easier way for the worldwide adoption in the real estate projects.
