| Abstract |
The objective of this research is to derive the factors that affect construction delays in apartment housing projects for effective construction planning and controls and furthermore for proactive claim managements. Based on the contractors' points of view, interview and questionnaire surveys with construction practitioners were conducted to derive delay factors by each of major trades such as earth work, superstructure work, masonry work, window/door work, and interior finish work. The survey results were analyzed statistically to determine the degree of importance on each of the delay factors. The result identifies major delay factors on each trade and provides the comparison of the degree of importance among work trades. The result also shows that the importance index of the delay factors on superstructure and earth works are higher than those of the other works. In addition, the result indicates that the delay factors are different depending on the work types. |
