Why monitor

Why Monitor Performance?

  1. Provide an early warning.
  2. Validate design assumptions.
  3. Identify a looming problem.
  4. Reveal unknown changes.
  5. Improve performance.
  6. Acquire state-of-art knowledge.
  7. Inform stakeholders.
  8. Satisfy regulators.
  9. Reduce litigation.
  10. Confirm ongoing structural integrity

Why Structural and Infrastructure Health Monitoring?

  1. Safety
    • Safe use of questionable topography
    • Early warning of deleterious changes
    • Reduced risk of major accidents for unknown reasons
  2. Ageing and cost
    • Early detection of malfunctioning areas helps to define appropriate and lower cost maintenance activities.
  3. Economy
    • Cost reduction
    • Optimization of more expansive construction materials.
    • Optimization of efficiency
  4. Sustainable development.
    • Preserve the existing infrastructure
    • Anticipate the effects of the announced climatic change
  5. Management and decision tool.
    • Need to assess the behavior of the structure on real time

Why Earth and Hydraulic Works Monitoring?

  1. For all new projects: the design is based, in part, on unknown parameters
    • Soil heterogeneity
    • Design assumptions
    • Changing external stresses (climate, traffic)
  2. For risky works
    • Construction area less and less favorable
    • Detection of random events : cavities, breaches, leaks, settlements
    • Seismic zones
  3. For existing and old works
    • Assess the ageing status and follow-up
    • Construction material and design methods unknown
