Asset Management

• Improved Asset Condition
• Increased System Efficiency
• Prolonged Asset Life
• Reduced Operating Costs and Optimized Capital
  Expenditures
• Reduced Overall Life-Cycle Costs
• Reduced Risk of Environmental Non-Compliance
• Improved Customer Services

Asset Management Stages

Typical Methods of Data Management

• All Paper Survey Results and Work Orders Filed
  Away in a Cabinet or Binder.
• Video in difficult to use formats
• Most Data in the Heads of Long-Term Personnel

5
Consequences of Old Methods

• Associating Survey Information with the Asset is
  Labor Intensive, thus Costly.
• No Effective Tools for Sorting and Querying
  Historical Data.
• High Risk of Actually Losing Important System
  Data at Any Moment

Inventory of Assets

• From GIS or manhole inspections

Data Validation

• Assess System Connectivity Situation

Criticality Assessment Impact of Failure

• Impact of Failure Query.
• Personalized for the Individual Collection System
  (Highway Names, MH Depths, etc.).
• Assigns Scores Depending on Proximity to
  Geospatial Areas of Interest (Water, Rail, Public
  Services, Bridges, Schools, etc.).
• Then Sums Up the Scores and Sorts Critical Pipes
  and Manholes to Prioritize for Condition
  Assessment Surveys.
