  9. SHM is about all of this and more…

  10. SHM has evolved from being a research topic…

  11. …to being an Industry

  12. An « Industry » is a meeting place between Supply and Demand…

  13. … between Cost and Perceived Benefits

  14. This presentation is about defining Cost and Benefits from a Customer-Supplier Relationship Perspective

  15. WARNING: This presentation has no sophisticated financial models or a universal recipe for commercial success…

  16. … just some personal observations derived from practice

  17. Defining Cost Capital Investment + Operational Costs

  18. Cost: Capital Investment SHM design costs, including: Integration with the structure’s design Planning and project management

  19. Cost: Capital Investment Hardware costs: Sensors Cables Data acquisition and management hardware Communication

  20. Cost: Capital Investment Installation costs: Integration with building schedule Configuration Commissioning Reporting

  21. OperationalCosts System maintenance Spare parts and consumables Energy Communication

  22. OperationalCosts Data Management Publishing Archiving

  23. OperationalCosts Data analysis Interpretation Reporting

  24. Total Costs Typically 0.5 – 3% of new construction costs Hardware cost typically less than 50% of total cost Total Investment+ recurring costs are important for the owner

  25. Identifying Benefits

  26. Hard Benefits vs. Soft Benefits

  27. Capital Value Hard(ly) Benefit
