Tube Lines' approach to integrated risk management under the PPP contract

A public-private partnership (PPP) contract was put in place to manage and upgrade the infrastructure of the London underground network in addition to recovering the backlog from years of underinvestment. Tube Lines, as the company responsible for the Jubilee, Northern & Piccadilly Lines, has developed an innovative approach to modelling safety risks as part of our overall asset management plan. This presentation describes the reasons for the approach, along with its development and use within the company.
