Abstract

Effective risk coordination is critical to the success of complex infrastructure programs, where multiple stakeholders and dynamic environments increase uncertainty and potential adverse impacts. This paper presents a comprehensive exploration of designing communication and escalation models tailored to enhance risk coordination. Grounded in established principles of risk communication, the study emphasizes transparency, clarity, and interactive dialogue as foundational to managing risk information flow. It further develops communication models that incorporate key components such as message content, structured information exchange, and feedback mechanisms to ensure timely and clear dissemination of risk data. Escalation models are defined by objective criteria, triggers, and structured paths to systematically elevate risks to appropriate decision-making levels, ensuring prompt and coordinated responses. The integration of escalation processes with governance structures underscores accountability and enhances responsiveness. The findings highlight practical implications for infrastructure program management and suggest avenues for future research, particularly concerning empirical validation and technological advancements. Ultimately, the proposed models offer a robust framework for improving risk governance and project resilience in infrastructure programs.
