Bridge maintenance parameters: a case study of railway bridges in Pakistan

Abstract

Ensuring railway bridges' safe and efficient operation is fundamental to infrastructure management. This study comprehensively analyses critical parameters in bridge maintenance, encompassing maintenance standards, regular inspections, funding, training, and technology adoption. Leveraging a Google survey administered to Pakistani railway bridge engineers and inspectors, the research provides insights into the existing maintenance landscape and avenues for enhancement. SPSS analysis was employed to scrutinise the survey data. Timely repairs, utilisation of high-quality materials, and the proactive replacement of damaged components emerge as pivotal factors underpinning effective bridge maintenance. However, the perceived suboptimal standard of maintenance for Pakistan Railways (PR) bridges necessitates substantial improvements. While current maintenance procedures exhibit moderate effectiveness, they warrant refinement. Overcoming the challenges of insufficient funding and inadequate training is paramount in bridge maintenance. Furthermore, harnessing technological advancements offers promise but demands specialised training and considerable investments. This study highlights the crucial significance of regular inspections, emphasising the urgency of increasing inspection frequencies in Pakistan. These findings are a foundation for developing more efficient and effective bridge maintenance programs, safeguarding the longevity and safety of railway bridges within the broader transportation framework.
