The impact of major delay factors on project’s phase: A comparative study

Abstract

Although works have been done in the past to identify the main causes of construction delays and their impacts, there was a gap in the study associated with the project life cycles. The main purpose of this study was to identify the impacts of the main causes of construction delays in projects life cycles defined for this study. With this in mind the major delay factors identified from the review of previous research works of selected countries, including Malaysia, Egypt, Hong Kong, and Jordan categorized into the project life cycle defined for this paper. Subsequently, the aggregate average relative importance was calculated for each phase and it was found that on the average the major delay factors play significant role in planning and design phase. And if the causes of construction delays in this phase can be controlled, it will play an important role in completing construction projects on time.
