Condition & Criticality – How Fort Wayne Built their Asset Management Risk Model

The City of Fort Wayne’s Utilities Engineering (CUE) linear asset management program is continuing to evolve as the Utility strives to deliver high value services and be the utility of choice. This paper will look specifically at the Utilities collection system risk, condition, and criticality scores. The presentation will cover the following:Briefly cover the foundation of a risk model: scoring the condition of the asset, ranking the criticality of the asset, and multiplying them together to come up with the risk. The paper will look at Utilities risk matrix which is weighted toward criticality.The reader will learn how the Utility selected its criteria for the condition matrix and criticality matrix. The reader will walk through the different criticality criteria and how they were selected in relation to a triple bottom line. The paper will look at how the Utility developed their estimated useful life for different sewer pipe materials.Finally the readers will learn how the Utility built the GIS model to display the data and will look at the map results. The paper will also share the Utilities iterative process of adjusting its criteria and scoring to be able to come up with a truly representative data set and maps. The paper will also look at some of the results from the data analysis and how this tool is driving the Utilities sewer rehab program.The paper will provide communities with knowledge of where to begin their risk analysis based on condition and criticality criteria. Additionally, the Utility will share the results of its program, which will be helpful in making decisions about sewer rehab work.
