A S S E T M A N A G E M E N T is a core business principle and practice that will underlie everything an organization does. Decision making requires the data collection, management and analysis. All municipalities and utilities are made up of assets either linear or buried assets or vertical assets. For a road or street system, these are the physical assets which include the street , pavement , curbs, gutters and other components. For a water utility, these are the physical components of the system and can include: pipe, valves, tanks, pumps, wells, hydrants, treatment facilities, and any other components that make up the system. All physical assets, except for land, degrade and lose value over time as the asset ages and deteriorates through use. Costs of operation and maintenance will increase as the assets condition deteriorates. At some point , the asset owner will need to analyze the •inancial impacts of funding additional maintenance or making repairs or replacing the asset . Not all assets are created equal and not all failure is created equal. Some assets may be highly critical to a sys- tem's operation, while others are not. Certain types of assets may be criti- cal in one system location but not in another. Each system must carefully examine its own assets to determine which are critical and why. To effec- tively manage the complexity of public infrastructure and assets, GIS must be at the heart of the data collection so- lution. GIS-centric technology serves as the system of record for risk-based assessments. Basic data identi•iers— such as asset attributes, location, age, condition assessments, failure history and more — provide valuable informa- tion for calculating risk. A computerized maintenance and management system (CMMS) which collects cost (equipment , labor, ma- terials) in work orders and inspec- tion asset condition data provides the foundation of making cost-effective decisions. Ninety percent of water and wastewater utility assets are land based with a GIS location which can be recorded in a geo -database. Using a GIS -centric platform such as data from Cityworks Operational Insights and ArcGIS, an asset management risk model can be developed. If a utility does not maintain an asset , the con- dition will degrade creating the need 42 T R E N C H L E S S T EC H N O LO GY O C TO B E R 2018 Understanding the Basics of Asset Life Cycle Costing and Risk Based Criticality Scoring Using a GIS Centric Approach By Greg Baird
