Preventive Maintenance
Why scheduled inspections and servicing remain central to infrastructure reliability.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Why scheduled inspections and servicing remain central to infrastructure reliability.
Core system ideas
Preventive maintenance addresses age- or use-related failure modes before breakdown.
Intervals should reflect manufacturer guidance, experience, condition and consequence rather than calendar habit alone.
Maintenance deferral can create hidden risk even when short-term service appears unaffected.
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.
