Abstract

Variation order involves adding, omitting, or altering activities from the original scope of work. It has a multitude of negative impacts on the project’s duration and budget. The objective of this research is to investigate the main causes and impacts of variation orders in Egyptian construction projects from the perceptions of contractors, consultants, and owners. The relative importance indices of these factors are computed by analysing thirty-three questionnaire surveys. Furthermore, the rankings of this study are aggregated with other studies to determine the top five factors affecting and resulting from variation orders in many Arab countries. The results showed that the most significant cause and impact of variation orders are change in the country’s economic conditions and delay in project completion, respectively. This study aids project managers and construction practitioners in identifying the root causes of variation orders to mitigate and eliminate their negative impacts on the construction projects
