Asset Classification Hierarchy Asset Elements Asset Sub-Elements (if Applicable) Structures (not bridges or otherwise in the national bridge inventory) Drainage Structures Overhead Sign and Signal Structures Retaining walls (Earth retaining structures) Noise barriers High Mast Light Poles Traffic Control & Management – Active Devices Signals Signals, beacons, flashers, ramp meters ITS Equipment Cameras, variable message signs, detection devices/sensors, highway advisory radios Network Backbone Hubs and nodes, fiber, cabinets, software Assets selected for further study in bold Many agencies already have a hierarchy in place – typically driven by which divisions maintain assets This proposed hierarchy represents a starting point to establish an enterprise approach through an inventory of record (down to the lowest maintainable unit level) – important component of an integrated EAMS Logical, generally-agreed upon asset classification hierarchy – divided into: asset classes, asset elements, asset sub-elements Transportation Asset Management for Ancillary Assets

State-of-the-Practice Internationally-accepted standards for the management of physical infrastructure assets (ISO 55000 and PAS 55) Considerable body of knowledge related to the management of pavements and bridges in the U.S. Passage of MAP-21 resulted in new asset management requirements – primarily focused on pavement and bridge assets Much of the literature on ancillary asset management captures state-of-the-practice Generally no industry standards for the management of ancillary roadway assets Summary of literature related to ancillary asset management – generally no industry-accepted standards for the management of ancillary roadway assets Transportation Asset Management for Ancillary Assets

Life Cycle Management Principles Project team used the terminology and elements of asset management as outlined in PAS 55 and ISO 55000 Management system (ISO 55000): a set of interrelated or interacting elements of an organization to establish policies and objectives, and processes to achieve those objectives Asset management information (PAS 55): meaningful data related to assets and asset management Asset management information system (PAS 55): a system for the storage, processing, and transmission of asset management information Establishes common definitions Ensures consistency of approach Transportation Asset Management for Ancillary Assets

Key Elements for Asset Management Linkage between levels – everyday asset management activities should be tied to AMPs – ‘Line of Sight’ concept Consistent with industry best practice and international standards PAS 55 and ISO55000 MAP 21 requirements for risk-based TAMPs Initial focus on pavements and bridges BUT agencies encouraged to include all assets within highway ROW Transportation Asset Management for Ancillary Assets

Asset Life Cycle Stages and Key Decision Points Asset Life Cycle Stages (consistent with PAS 55 definition) and associated key decision points Foundation for definition of life cycle management business processes Transportation Asset Management for Ancillary Assets

Integrating Ancillary Assets into Enterprise Asset Management Systems An asset management information system could be one tool/system that provides all the capabilities (shown in the “asset management information system” box) or multiple systems An “enterprise” asset management system should integrate with other key agency systems to both send and receive information Generally initial step to incorporating ancillary assets into EAMS is to upgrade to or procure a new enterprise asset management system Additional steps Defining an asset classification/hierarchy to be used consistently through the agency and used in the enterprise asset management system Establishing the asset hierarchy and inventories of record for the hierarchy Collecting asset inventory data and entering this data into an enterprise asset management system or transitioning available asset inventory data to an enterprise asset management system linked to the inventory of record Collecting data on asset condition and entering data into an enterprise asset management system linked to the inventory of record Capabilities of mature systems include: Determining future condition of assets based on research or past data Identifying lifecycle management activities and activity timing to most efficiently manage the assets Transportation Asset Management for Ancillary Assets

Template for Life Cycle Management Business Process Guidance Enterprise-level Inventory Interaction between Asset Classes Relationship of Asset Class to Overall Safety, Mobility, and Asset Performance Asset Specific-level Inspection and Condition Assessment Level of Service/Performance Metrics Lifecycle Management Plans and Practices Asset Prioritization Decision Support Additional Sections Asset Element-specific Considerations Additional References Recommended business processes divided into enterprise and asset-specific levels Agencies should consider business processes at BOTH levels when developing TAMPs Enterprise-level Captures interdependencies between and within particular ancillary assets AND also between particular ancillary assets and the overall roadway asset management system E.g., each asset should have a inventory of record at the enterprise level but inspection and condition asset procedures are likely to differ by asset Inventory: describes link to inventory of record; discusses whether a 100% inventory should be maintained and the implications of a less than complete inventory Interaction between Asset Classes: how a particular asset element impacts the performance of others; an asset element’s ability to provide safe, reliable, and cost effective transportation to the roadway user Relationship of Asset Class to Overall Safety, Mobility, and Asset Performance: risks to the performance of the entire roadway system arising from the performance of a specific asset element Asset Specific-level Inspection and Condition Assessment: frequency of inspection and condition assessment methodology Level of Service/Performance Metrics: discusses condition ratings and LOS; LOS and/or condition targets should balance cost, performance, and risk Lifecycle Management Plans and Practices: recommendations related to life cycle management activities, application of LCCA, other implications on long-term plans and strategies Asset Prioritization: characteristics that drive prioritization for inspection, condition assessment, life cycle management activities (within an asset element and between asset elements and classes) Decision Support: tracking and analyzing costs to inform future needs estimates and estimate remaining service life Asset Element-specific Considerations: discusses any unique implications for asset management for selected elements based on their purpose and intended functionality Additional References: sources of further information Transportation Asset Management for Ancillary Assets

Sample Template – High Mast Light Poles Asset Element-specific Considerations Provide proven improvement to nighttime driving conditions Height presents challenge for inspections Enterprise-level Inventory Recommended complete inventory with basic data items including location, condition, and age Interaction between Asset Classes Failure can result in closure of crucial links in the highway system Relationship of Asset Class to Overall Safety, Mobility, and Asset Performance Provide illumination that can improve safety Results of the high mast light pole guidance template provided as an example Transportation Asset Management for Ancillary Assets

High Mast Light Pole Template Asset Specific-level Inspection and Condition Assessment Visual inspections with binoculars or telescopes Remotely-operated inspection devices with video cameras NDT techniques to inspect base plates and anchor rods Inspect at least every 4 to 5 years – potentially greater frequency for anchor bolts which are known to loosen over time Level of Service/Performance Metrics Typically simple condition rating scale comparing current performance against originally intended function Lifecycle Management Plans and Practices Track maintenance activities and forecast future activities such as anchor bolt tightening, repair, or replacement Account for need to replace lamps Asset Prioritization After high-wind weather events prioritize inspections Prioritize inspections in areas with known nighttime safety issues Decision Support Track maintenance costs to inform future needs estimates Estimate remaining service life based on installation date and age Transportation Asset Management for Ancillary Assets
