In recent decades, the construction industry has developed rapidly. Delay was and remains one of the most important challenges negatively affecting not only this industry but also the economy and sustainable development. This study aims to conduct a comprehensive analysis of the delay factors in reconstruction projects because of the vital importance of these types of projects. This is the first attempt to conduct such an analysis for reconstruction projects in particular, and it is a continuation of the previous case study, which was considered one of the most important reconstruction projects in the Middle East region. The previous study focused on determining the types of delay factors used in this project. It is necessary to carry out advance in-depth analysis to sort the delay factors based on their effect on the project plan. In order to achieve the study goal, 93 questionnaires were distributed by hand to experts working on the project: some of them working the day shift, and the others working the night shift. The questionnaire results were analyzed and delay factors were sorted in descending order according to the relative importance index (RII). The three main factors affecting the overall reconstruction project duration were site restrictions and conditions, electrical and mechanical rerouting works, and design buildability and adjustment.
