Waste Minimization in Construction Sites Based On Lean Construction Principles – Case Study

C. Bhaskar, P.Naveen Kumar

Abstract


The adoption of lean construction principles within construction industries has led to notable improvement has improved time-to-market, reduced production cost, improved quality of the work. Construction site waste contributes to the large quantities of construction waste that are generated by the construction industry every year. Increased economic growth and urbanization in developing countries has led to extensive construction activities that generate large amounts of wastes. This work aimed at identifying the main sources and causes of materials waste on construction sites arising from storage and handling of high waste generating building materials and employing the Lean Construction approach to reduce such waste and to identify the barriers for adopting the lean concept. Minimizing material wastage would not only improve project performance and enhance value for individual customers, but also have a positive impact on the national economy. This work will be further intended to verify and re-evaluated the status of existing productivity and performances on construction activities and processes for local construction industries. This is meant to have a clearer picture on how “lean” in local construction industry performed currently under the compilation of new measurement parameters particularly on waste and cycle time pertaining to the concepts and principles of Lean Construction. This study mainly focuses on implementation of the tool like Relative Importance Index has been done for finding the cause and the effect of the various wastages at the construction industry. By way of choosing some major construction activities and careful observation of them for the extraction of the causes of the wastage generation has been done in this report.
