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

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:

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.
