Making Scrap Disposal System More Lean and Mean

Construction waste generation is inevitable at project sites. Though there have been advancements in the resource monitoring tools which have reduced the wastes considerably, but still, construction industry continues to be the major waste and scrap generator. The large quantity of scrap generated not only affects the environment but also has very severe impact on the project execution. As the building projects have interdependency of large number of activities and are related to have parallel operationality. Considering the logistic issues at a space-constrained project site like the one in this study, timely and efficient scrap disposal is crucial. To ensure this, a well-defined process chart is designed. Since the system involves a lot of approvals, reconciliations, and collaborations, this process chart facilitated rigorous follow-ups and timely identification of the bottleneck. The scrap disposal is reviewed along with the construction program to have seamless coordination and reverse-phased scheduling. With this incorporation, the project site was able to dispose approximately 1500MT of scrap in a planned manner which was in alignment with the construction program.
