Regression Technique-based Productivity Estimation conducting Construction Delay Factor Analysis on Interior Works in High-rise Building Construction

공기지연요소분석을 이용한 회귀분석 기반 초고층 내부공사의 생산성 예측

The construction projects contain a lot of variables and risk affecting productivity. The duration of the project must be recognized important as for quality, unit cost and safety. There is need for improving work efficiency by investigating relationship of works to prevent delay. This study focuses on analysing the delay factors of steel staircase system to suggest regression model that enables construction productivity estimation. The position of the observers and construction delay factors were expressed by the independent variable of the regression model and productivity was expressed by a dependent variable. This paper suggests quantitative productivity and it is expected that will be helpful estimating application in construction new technologies.
