Critical infrastructure guide
Infrastructure Lifecycle Renewal
Plan rehabilitation and replacement before assets become emergency projects.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Plan rehabilitation and replacement before assets become emergency projects.
Core system ideas
Lifecycle planning spreads investment over time and reduces reliance on crisis replacement.
Rehabilitation can extend useful life when the underlying asset remains suitable.
Replacement can also provide an opportunity to improve resilience, efficiency and capacity.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
