Lean and green philosophies have more or less remained separate and parallel initiatives within the construction sector. Intuitively there seems to be significant overlap between the two philosophies. As these have separately matured, there is now a need to synthesize the two parallel streams into one to garner more benefits for the industry. Efforts to demonstrate the overlap between lean and green concepts is available in literature. However, an integration framework has not been developed or reported. As such this paper, which is part of an on-going research, identifies operational and tactical connections of lean and green philosophies, with an aim to provide a conceptual integration framework. The authors envision that Building Information Modeling (BIM), a friend of both lean and green philosophies can provide the needed linkage between the two. With BIM as the common tool that acts as a catalyst, a conceptual framework for lean and green integration is developed. This framework is tested using three case studies and findings reported in the paper. Preliminary findings show that projects that use BIM can more easily integrate lean and green and add value.
