Schedule Performance Analysis of Infrastructure Reconstruction Projects Due to Extreme Events

Abstract

Timely post-disaster reconstruction of transportation infrastructures is vital, as it affects the pace of the overall physical and economic recovery of the disaster-ravaged area. To ensure the completion of the project within the optimum amount of time, it is important to know what factors affect the duration of the project, but it is difficult to find a comprehensive list of those factors in the current literature. This study aims to fill that knowledge gap by identifying the factors that affect the timely reconstruction of transportation infrastructures (PRTs) following a natural disaster. A survey was developed and distributed to collect data for this study, and the responses were analyzed statistically. It was found that the possibility of schedule overruns increases with the levels of complexity and damage. Hurricanes in particular cause sudden shortages of resources (experts, suppliers, laborers, materials, and equipment) that reduce the productivity and increase the duration of reconstruction projects. The results of this study will help practitioners and engineers take steps to complete reconstruction projects within the estimated schedule.
