Priority Order of Reinforced Concrete Work for Inspection Applying 6 Sigma - Minimize time of additional correction work-

6시그마를 이용한 철근콘크리트 공사 검측항목 우선순위 선정 - 수정작업 시간 최소화를 중심으로 -

The building construction industry of Korea was going through difficulties in improving productivity and competitiveness in international market. Therefore we expected to see the improvement in productivity by applying six-sigma based approach to general reinforced concrete construction work. As a result of applying DMAIC method, one of 6 sigma tools, we found that the most effective inspection items are 'Gap of forms' and 'status of clean'. We could see from this case study that the percentage of additional work days has decreased to 37.7% as a result of applying six-sigma based approach to reinforced concrete construction.
