Sustainability-related risks and risk management frameworks have been introduced in the literature to help project managers identify and manage critical risks influencing project sustainability. Theoretically grounded in the framework of Monte Carlo Simulation, this paper introduces and operationalizes a new process for prioritizing sustainability-related project risks using risk matrix data. Sustainability-related construction project risks have never been assessed relative to different confidence levels across the risk matrix-based exposure zones. The application of the proposed process on the construction projects completed in the United Arab Emirates reveals that the conventional risk prioritization scheme undermines the importance of tail risks (unexpected events), whereas such risks are captured in the proposed process. In contrast to the most critical risks identified using the conventional scheme such as shortage of client’s funding, insufficient or incorrect sustainable design operation, and design changes, the proposed process prioritizes risks such as poor productivity of labor and equipment in sustainable construction, unreasonable tight schedule for sustainable construction, and poor scope definition of sustainable construction. The proposed process is generalizable to prioritizing risks influencing sustainability in international construction projects and beneficial for enhancing project sustainability as there is a huge uncertainty associated with sustainability-related risks.

文献中引入了与可持续性相关的风险和风险管理框架，以帮助项目经理识别和管理影响项目可持续性的关键风险。从理论上讲，该模型基于蒙特卡洛模拟（Monte Carlo Simulation）框架，介绍并实施了一种新的过程，该过程使用风险矩阵数据对与可持续性相关的项目风险进行优先级排序。从未针对基于风险矩阵的暴露区域中不同的置信度评估与可持续性相关的建设项目风险。在阿拉伯联合酋长国完成的建设项目中采用拟议的流程表明，传统的风险优先排序方案破坏了尾部风险（意外事件）的重要性，而此类风险则在拟议的流程中被捕获。与使用常规方案确定的最关键的风险（例如客户资金短缺，可持续设计的不足或不正确以及设计变更）相比，建议的流程优先考虑了以下风险，例如可持续建设中劳动和设备的生产率低下，进度安排不合理对于可持续建设，以及对可持续建设范围界定不佳。提议的过程可以推广到优先考虑影响国际建设项目可持续性的风险，并且由于与可持续性相关的风险存在巨大的不确定性，因此有利于增强项目的可持续性。拟议的流程优先考虑了以下风险：可持续建筑中劳动和设备的生产率低下，可持续建筑的时间表不合理，可持续建筑的范围定义不当。提议的过程可以推广到优先考虑影响国际建设项目可持续性的风险，并且由于与可持续性相关的风险存在巨大的不确定性，因此有利于增强项目的可持续性。拟议的流程优先考虑了以下风险：可持续建筑中劳动力和设备的生产率低下，可持续建筑的时间表不合理，可持续建筑的范围定义不当。提议的过程可以推广到优先考虑影响国际建设项目可持续性的风险，并且由于与可持续性相关的风险存在巨大的不确定性，因此有利于增强项目的可持续性。
