An investigation of the applicability of sustainability and lean concepts to small construction projects

Abstract

Sustainability and lean concepts can both be applied to the construction industry to help minimize waste. Although both concepts work to alleviate similar problems, organizations struggle to integrate the concepts. This paper examined projects of different sizes and in different environments within the Midwestern United States to determine what aspects hinder the integration of sustainability and lean concepts within the region. Professionals associated with the industry were interviewed to identify sources of waste for lean and sustainable projects. From the case studies, various aspects of waste that exist in construction projects were recognized, and a comparison of the interaction of lean and sustainable concepts was documented. A process for planning throughout the entire construction process was determined so that waste can be reduced and the integration of lean and sustainable concepts is more achievable.
