AREA OF LINKAGE BETWEEN LEAN CONSTRUCTION AND SUSTAINABILITY IN INDIAN CONSTRUCTION INDUSTRY

Purpose- The purpose of the research paper to study the area of linkage between lean construction (LC) and sustainability in Indian construction industry and rank the identified attributes on the basis of the responses given to their severity to construction projects in India. Design/methodology/approach- The research was conducted by a structured questionnaire that was sent to 180 professional working in Indian construction industry. This questionnaire requested the respondents to give a score to the 26 attributes identified that are 15 lean construction tools for enabling sustainability and 11 attributes as area of linkage between lean construction and sustainability in Indian construction industry through literature review. They were asked to rate the attributes on a Likert scale rating of 1 to 5. The data collect than analysed using relative importance index and reliability analysis. Findings- The research study identifies the top five Significant lean tools for enabling sustainability are: first run studies, six sigma, kanaban, last planner system and visualization tool having relative importance index (Rii) of 0.80, 0.781, 0.779, 0.77 and 0.75 respectively. Most significant area of linkage between sustainability and lean construction are: resource management, waste reduction, energy minimization, elimination of non-value added activities and health and safety improvement as the outcome benefits of linking lean construction and sustainability in Indian construction industry having a relative importance index of 0.83, 0.779, 0.776, 0.77 and 0.76 respectively.
