Risk factors in construction projects during unrest period in Yemen

Construction projects are inherently exposed to various risk and uncertainties. Numerous studies have identified risk factors in construction projects in developed and developing countries. Yemen has witnessed revolutions and wars during the past six years, which affected the construction sector among other sectors. The purpose of this paper is to determine risk factors during the unrest period in Yemen. A list of 72 risk variables was developed based on the literature review followed by a questionnaire survey to determine relevant variables and factors. The results of this study explored new components of risk variables, namely environmental, resource-related, technical, conflict, design-related, profit-related, liquidity and revolution, and change. In addition, the results indicated critical risks affecting construction projects and main strategies to respond to them. The results of this paper provide an essential step for managing risks, so project managers and other professionals can ensure good project performance. However, further study is required to investigate the effectiveness of risk response strategies proposed in this paper
