Infraviability describes the assessment of infrastructure systems' long-term viability, resilience, and adaptability under evolving environmental, economic, and social conditions. It evaluates performance, maintenance needs, lifecycle costs, and risk exposure to inform planning and investment decisions. Practitioners apply quantitative models, scenario analysis, and multi-criteria evaluation to measure infraviability across transport, water, energy, and built environments. Results guide interventions, policy adjustments, and funding strategies to enhance service continuity and reduce lifecycle costs and disruptions.
