Application of Six Sigma in Construction Industry

Construction plays an important role in the economic growth of a nation. This project deals with the quality standards and customer satisfaction. The aim is to evaluate the quality of a multi storey building by using six sigma. Six sigma concepts are used to reduce the variation and eliminate the root cause of defects. The data collected from the defect assessment sheets are calculated by study done in a residential building and the quality of brickwork, concreting, plastering, flooring and painting are analyzed. Although Six Sigma has been implemented in the manufacturing and other services industries. This study described the Six Sigma concept as a quality initiative that may be applied in the building industry. The principles, methodology, and metrics of Six Sigma are first discussed. The application of Six Sigma for improving the quality of internal finishes during construction is also explained. For that a case of residential building is done to find out the defects in brickwork, concreting, plastering, painting and flooring. These defects are then evaluated by applying DMAIC methodology of six sigma. Before applying DMAIC, the sigma level is calculated by defects per million opportunities DPMO . It also suggests various improvising methods for quality of building by minimizing the defects. In this paper, DMAIC Define, Measure, Analyze, Improve and Control phase of six sigma is used to improve the quality of the building. The cause and effect diagrams and pareto charts are done in E draw max software and MS Excel. This methodology is applied to enhance the quality of the existing process by analyzing the defects, percentage of occurrence, possible causes, effects of defects and recommendations to overcome them.
