The objective of this research is to develop a primer, guide, spreadsheet template, and a list of resources to help airports develop an asset registry. The primer will cover the following, at a minimum: Purpose and benefits of asset registry for new and existing assets; Summary of asset management and common definitions; Criteria for defining airport assets; Role of asset hierarchy when developing an asset registry; Common asset information and attributes for various asset classes (e.g., fleet, vertical, and horizontal airport infrastructure assets); and Overview of applicable standards (e.g., ISO 14224, ISO 55000, International Infrastructure Management Manual, Institute of Asset Management). The guide should address the following topics as they relate to the development of an airport asset registry, at a minimum: Methods for identifying and engaging potential internal and external stakeholders; Methods for data collection for new and existing assets; Recommended practices for maintaining an asset registry; Identifying and defining asset management related systems (e.g., Enterprise Asset Management, Geographic Information System, Building Information Modeling, Computerized Maintenance Management System, Supervisory Control and Data Acquisition) including technical touch points; Developing a project plan for phased asset registry implementation, including demonstrated business value at defined data collection milestones and deliverables; Recommendations for scaling the asset registry based on airport size, asset management program maturity, available data, and resources; Incorporating data governance considerations (e.g., naming conventions, asset location, approval authority, management of change); and Other considerations (e.g., stakeholder communications, training, organizational change management, Responsible, Accountable, Consulted, and Informed (RACI) matrix). The spreadsheet template should include the following features, at a minimum: Editable spreadsheet with recommended common and specific asset attributes for vertical, horizontal, and fleet assets; Examples for each asset category and asset hierarchy; and User guide with instructions for creating an asset registry using the spreadsheet template. The list of resources should list existing standards, handbooks, and ACRP and non-ACRP products to facilitate development and implementation of an airport asset registry.
