Synthesis of Information Related to Highway Practices. Topic 54-06. Ancillary Asset Data Stewardship and Data Models
Some state Departments of Transportation (DOTs) have started tracking some ancillary assets, that is, assets other than pavement and bridges, in their Transportation Asset Management Plans (TAMPs), but most have not, even though they inventory and manage many of these ancillary assets. There is growing interest in creating and maintaining dynamic inventories of ancillary assets that provide centralized access to current, accurate ancillary asset information. Maintaining this ancillary asset information is a cross-functional activity within the DOT. The Federal Highway Administration is currently deploying Digital As-Builts through its Every Day Counts Round 6 (EDC-6) initiative. DOTs interested in implementing Digital As-Builts recognize that the as-built data primarily serves post-construction uses. DOTs need to identify their asset data stewards and access the asset data models before they can implement collection of digital as-builts. DOTs also recognize that the majority of asset inventory information is created in design and should only need to be verified or updated in construction. Consequently, DOTs are harnessing technology to automate the creation of asset inventory information and are developing solutions to extract the information for use/update in construction and delivery to the asset data steward. Updates of ancillary asset data, including inventory and condition, may also be used to make programmatic decisions. The objective of this synthesis is to document state DOT practices related to data models and data stewardship of ancillary assets. Information for this study was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected DOTs. Case examples of five state DOTs provide additional information on practices for identification, investigation, design guidance and requirements, prevention, and mitigation of surficial slope failures. Hala Nassereddine of the University of Kentucky Research Foundation, Lexington, Kentucky, collected and synthesized the information and wrote the report, supported by Bassam Ramadan, Rachel Catchings, Gabriel Dadi, and Ashtarout Ammar, all of the University of Kentucky Research Foundation. The members of the topic panel are acknowledged on page iv. This synthesis is an immediately useful document that records engineering considerations and practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice continues, new knowledge will be added to that now at hand.
