Infrastructure projects frequently encounter delays because of conflicts existing among various stakeholders. The traditional conflict management usually concentrates on cost and schedule. This paper creatively incorporates the environmental, social, and economic triple bottom line principles into a conflict management framework. It puts forward a sustainable development-oriented approach for resolving conflicts. By employing case studies from the Beijing Daxing International Airport and the Shanghai Xujiahui Center projects, the paper examines how this approach aids in identifying and resolving conflicts concerning resource usage, community impact, and long-term value. It offers practical guidance for effectively managing intricate projects.
