An Application of Analytic Network Process (ANP) to Assess Critical Risks of Bridge Projects in the Mekong Delta Region

Abstract

Risk management is one of the critical factors contributing to infrastructure project success. Risk assessment enables both practitioners and decision-makers to identify and analyze potential risks and quantify risk impacts on project performance in terms of time, cost, and quality. Even though many studies attempt to investigate the risk of construction projects with the consideration of technical, organizational, and legal aspects, only a few studies deeply focus on identifying the critical risks of bridge projects with the examination of climate change impact. The current study concentrates on analyzing risks in bridge construction projects in the Mekong Delta region which has been significantly affected by climate change. An intensive review of previous publications and technical project reports from 2010 to 2021 was conducted to identify the list of potential risks and interviews and discussions with engineers and managers involved in bridge projects were carried out to identify critical risks of bridge projects. Analytic Network Process (ANP) method was introduced to evaluate the impact of such risks on the performance of bridge project implementation. The initial results of this study provide a holistic picture of risk management for bridge projects with the consideration of climate change impact. The findings can help the involved parties including owners, contractors, and project managers to assess particular risks and scheme backup plans to mitigate project delays and cost overruns.
