공기단축 기술의 개발 및 적용을 위한 공기단축 저해요인 분석

Reduction of construction duration is very important factor in construction productivity and have a strong influence on the reduction of material cost, labor cost, and financial cost. Thus, many technologies for reduction of construction duration have been developed. Many of them, however, cannot be applied in construction practice because of the difficulties and construction delays which arise from the legal or customary aspects other than the technological aspects. In this study, we conducted a survey of 122 engineers of construction companies to identify these legal or customary factors for difficulty and delay in detail which disturb the application of the developed technologies. Then we analyzed the importance and priority of the factors of difficulty and delay factors quantitatively and, finally, identified the appropriate countermeasures for them.
