Abstract

Focusing on repetitive works of construction, many research have been conducted about application of the learning curve effect. However, it is still controversial, especially on the high-rise project, since the productivity improvement from the learning curve effects are hard to prove. In the previous research, applicability of the learning curve was mainly derived from the labor productivity data. Although the research were based on the real data, they merely concentrated on the simple conclusion that the labor productivity had improved or not, instead of the process interpretation. Therefore, the purpose of this research is to analyze the influence factors of the learning curve effect in high-rise projects and elucidate the offset factors of the effect. Based on these factors, a model for estimating the labor productivity containing the concept of process learning is suggested. Through our research, traditional learning curve theory could be compensated and re-established with having more appropriateness for high-rise projects.

건설 프로젝트 내의 작업의 반복성에 주목하여 건설산업에의 학습곡선효과 적용에 관한 연구가 꾸준히 이루어졌다. 그러나 충분한 반복 작업을 가지는 초고층 프로젝트에서 학습곡선효과가 실제로 발생하는가에 대한 논란은 지속되고 있다. 이에 관해 기존의 연구들은 실제 건설 현장의 작업 생산성 데이터 분석을 통해 효과의 유무를 검증하였으나 작업 생산성의 향상 여부에만 초점을 맞추고 있을 뿐, 효과가 발생하는 과정에 관한 연구는 이루어지지 않았다. 이에 본 연구는 초고층 프로젝트에서 학습곡선효과가 발현되는 과정에 영향을 미치는 요인들을 분석하여 그 효과를 상쇄시키는 요인들을 찾고, 이를 반영한 작업 생산성 산정 모델을 제시하고자 한다. 이를 통해 기존의 이론을 보완하고 건설산업에서의 학습곡선효과 이론을 재정립하는 데 기여할 수 있다.
