Asset Management - Data Collection, Prioritization, Estimating, Funding Asset Management - Data Collection, Prioritization, Estimating, Funding Presentation Transcript

  • NYS County Highway Superintendents Association Summer Conference Asset Management Data Collection, Prioritization, Estimating, Funding August 29, 2011
  • Course Outline ObjectivePresent a method of keeping track of maintenance & repair needs and to develop a documented plan for addressing these needs
  • 5 Core Questions to Asset Management1. What is the current state of my assets?2. What is my required “sustainable” level of service?3. Which assets are critical to sustained performance?4. What are my minimum life cycle costs?5. What is my best long-term funding strategy?
  • 5 Core Questions to Asset Management1. What is the current state of my assets? • What do I own ? • Where is it ? • What condition is it in ? • What are the Maintenance Needs/Costs ? • What is the Replacement or Repair Cost ?
