crossings with a stretch of plain line and a crossover on a bridge over the London Underground’s Central Line and another single track.
But in reality, it became a complicated project on a junction that has strategic importance for freight flows. It turned out that the bridge needed substantial work to rectify age-related weaknesses. It was imperative that an assured life could be provided for the heavier upgraded S&C work and the Kirov crane required to lift the crossing threatened the structural integrity of the bridge.
The approach taken combined the bridge repair with the S&C work, minimising the impact on the availability of the asset for traffic and installing quality items with a long line and low maintenance requirements.
There were many challenges involved including supporting the bridge over the Central Line, enhancing the bridge to support additional ballast and heavier components and dealing with a large number of suppliers.
“Teamwork was described delivering extraordinary levels of co-operation such as one part of the team working differently to increase the contingency for other critical tasks. Delivering the whole task safely, on budget, and to time, the team achieved high levels of detailed planning in advance, providing for dynamic decision making during the blockade.
“Most impressive was the motivation of the team and each part of it not to complete the work as its main objective, but to deliver the best possible overall industry result.”
