Analysis of Crew Productivity and Influence Factor for Reinforce Concrete Work in the Nuclear Power Plant

원자력발전소 철근콘크리트 공종의 작업조 생산성 및 영향요인 분석

Few studies on crew productivity has been conducted, although the data is significant for time and cost estimation. Crew productivity data was collected for over 9 months from a nuclear power plant and analysed in order to identify factors driving the productivity. It was revealed that the crew productivity of form work and rebar work was 45.64($m^2/crew{\cdot}day$), 2.93($t/crew{\cdot}day$) on average respectively. The study also found that 'nightwork' and 'total work amount completed' were identified as drivers for the both works. Moreover, 'complexity of daywork' can lead to crew productivity deduction of about 77% for form-work and 81% for rebar-work. The productivity data collected and factors affecting the productivity will help managers to plan and control their similar works. This study will also be beneficial for those performing related studies.
