Asset Management Plans (AMPs) help agencies take an informed approach to bridge maintenance that will optimize expenditures and extend the life of their structures. B&N has worked with bridge owners to develop both system-wide and structure-specific bridge AMPs. This presentation will discuss the development of these plans and how agencies are implementing them to improve structure longevity and more accurately predict maintenance and repair costs, as well as case studies of system-wide AMPs for the cities of Goodyear, Arizona, and Delaware, Ohio.

The development of these plans started with data collection, including inspection reports, as-built plans, load rating summaries, and scour assessments. Recommended repair and maintenance actions were tabulated and prioritized into urgency categories based on the compiled data. Unit costs were developed for common repair types based on historical bid information. The results were collected in an electronic database that allows the owner to sort by structure or repair type. The final deliverable included anticipated maintenance and repair actions and costs for the duration of the plan.

The presentation will also share a structure-specific AMP developed for the Idaho Transportation Department. This plan was prepared for the I. B. Perrine Bridge, a 1500-foot-long steel deck arch that carries four lanes of US 93 over the Snake River in Twin Falls, Idaho. The plan development process included data collection, a structure field review, a risk assessment/workshop, an examination of alternative approaches to long-term maintenance, and maintenance manual development for the bridge. As with the system-wide plans, the final deliverable included anticipated maintenance and repair actions and costs for the remaining life of the bridge. Both system-wide and structure-specific AMPs help owners make informed decisions to minimize repair costs and to more accurately predict future expenses associated with maintenance, repair, and replacement of assets.

Presentation attendees will learn about the value that active management of bridge assets can offer to agencies when applied over an extended duration.
