15 15 23 May ARCADIS Manage Critical Assets

16 Crisis = Opportunity Move from reactive maintenance practices to scheduled preventative maintenance environment

17 Asset Management Plan Implementation and Continuous Improvement Develop Comprehensive Infrastructure Strategy Establish Vision, Mission, Goals and Objectives Develop Business and Financial Strategy Determine Service Levels and Performance Measures Define Initial Gaps and Key Opportunities

18 Core Asset Inventory Above Buried Ground Assets Assets Major Miles of assets pipe by category type, diameter, (Electrical/I&C, and Mechanical, age profile HVAC, Pumps, Valves, Other) Type (i.e. PVC, Concrete, Clay, Cast Iron, etc.) ID# and Description Diameter Date Installed (Total Miles of Water Mains (< 6 Inch Years Diameter, In Service >=6 inches - 1 Foot Diameter, Estimated etc) Total Useful Life / Age Profile industry (0-10 standards yrs, 11-20, 21-30, etc) Estimated Estimated expected Remaining life / industry Life standards Asset Value ($ Historic) Asset Value ($ Historic) and typical replacement cost
