Development of a quality control framework for the highway bridge using KPIs

Abstract

The development of essential transportation infrastructures such as roads and bridges is critical to the growth of the socioeconomic system. To sustain their service performance throughout the operational stage, it is challenging for the engineers to change their strategy from developing new facilities to maintaining the ageing infrastructure already in place. As a result, this article aims to suggest a quality control framework for managing highway bridges utilizing key performance indicators (KPIs). Case studies are being undertaken for several bridges, most located in European countries. The performance indicators (PIs) and goals (PGs) are formed during this. Then, following the assessment of the vulnerable zone, the derivation KPIs from those PIs are introduced and developed while considering various maintenance situations and time functions. The presentation includes a curated case study focusing on a steel truss bridge. This case study demonstrates the good potential for developing a long-term strategy for managing highway bridges on a lifecycle level.
