KPI for Bridge Management. A First Step for Bridge Digitation

Abstract

Introducing a bridge management approach helps asset managers to negotiate among budgets, needs, vulnerabilities and trade-offs. Often being understood as management of maintenance, bridge management is broader than that, and it aims to deliver pre-defined goals, in terms of measurable outcomes or service levels. The overall aim of asset management is to optimise the service level delivered by infrastructure over its life cycle. The focus of management should be on value to users or customers and not solely, nor even primarily, on cost or asset-replacement cost perceived by the infra-structure provider. Moreover, optimal service levels are not in a static form but evolving over time both over the short- and long-term. As an international review of best practices for road management shows, agencies today are moving toward a service-based approach for managing road networks and are moving away from a strictly condition-based approach. Customer-driven priorities, such as safety, reliability, comfort, have become the primary drivers for maintenance and renewal options. This paper is focused in Key Performance Indicators (KPI) selection procedure for an holistic bridge management what is considered by authors as the first step for a real impactful of the bridge digitation.
