Replacement of the existing 2 span wrought iron footbridge with a new single span aluminium footbridge in London.
The existing footbridge was a two-span wrought iron footbridge with brick abutments, brick wingwalls and a concrete deck in an overall poor to failed condition.
The latest detailed examination identified significant areas of breakdown of protective coating, resulting in corrosion to metallic elements throughout including loss of section to the main girders. There were also numerous brickwork defects to abutments and piers including fractured and spalled brickwork.
This was a challenging project due to the structure spanning both the West Coast Main Line and London Overground lines, and the only access being down a footpath within a residential area.

The aim of the project was to replace the existing two span wrought iron footbridge with a new single span aluminium footbridge. Works included:
The project was originally planned to be undertaken by another contractor who had delivered the design, however had failed to deliver the project on multiple occasions. Story Contracting were then contacted in March 2018 to tender for the project. The project team developed a new methodology, for example the use of Kirow Rail Cranes over mobile cranes, to deliver a project which could not be delivered by other contractors.
The contract was awarded in May 2018, starting on site in July thus dictating a quick turnaround. Story Contracting met the challenge of a short planning phase by engaging with suppliers and third parties quickly and effectively, utilising previous experience and local contacts.
The project was able to celebrate success and demonstrated best practice within the following areas:
Network Rail
The project involved regrading approximately 280 metres of the embankment to enhance structural stability and improve rail safety.
