Application of green, lean six-sigma methodology in framework construction process to reduce plywood consumption in Kuwait

This thesis is performed with the aim of reducing waste in the Construction Industry in order to reduce project costs and the environmental impact of such waste. For this purpose, lean, green six sigma (LGSS) methodology is developed to reduce causes of construction waste if formwork construction. A case study in Kuwait, the study performed to reduce the consumption of plywood due to formwork processes and standards. A large amount of plywood is wasted during the formwork process due to material properties. Using DMAIC problem-solving methodology helped in an in-depth understanding of the problem and improving the process performance. The process is visualized by a detailed Value Stream Map to represent plywood formwork process steps. The total plywood consumed for the formwork construction project is used to measure process performance and evaluate improvement. By identifying the main causes of the problem, we were able to implement waste reduction theories to the formwork construction model. Using an integrated model of aluminum formwork system (AFS) and plywood in processes, Aluminum formwork is used in constructing elements with high wood consumption to help in minimizing waste and cost due to the material features and sustainability.
