An Overview Of Strategic Bridge Life Cycle Modelling On The British Railway

Hamer, M J; Calvert, G S; Neves, L A C

Abstract

Bridges are critical assets for the safe, reliable, and functional operation of transportation networks. Infrastructure asset managers are responsible for ensuring that these bridges adhere to rigorous safety standards using the finite resources available to transportation agencies. Predicting future condition, forecasting required interventions, and developing equitable resource allocations from limited budgets is a challenging task for bridge managers. Network Rail is the infrastructure manager for the railway in Great Britain and is responsible for the management of over 26,000 bridges. Network Rail currently use a strategic ‘Tier 1’ model to forecast work volumes, condition outputs and expenditures for its portfolio of bridge assets. In this paper an overview of the existing strategic model will be provided alongside an account of recent work to transition the model onto a commercial asset investment planning solution, as well as a commentary of model limitations and future model requirements.
