Crowhurst Footbridge

This project was to remove the exiting transverse beams fabricate and install new transverse beams, X-bracing and over plating to severely corroded areas of the bridge.

Core samples needed to be taken from specific areas for chemical analysis to provide information of the composition of the steel work to ensure we had the correct procedures in place to undertake the work.

Once fabrication had been completed all welds were MPI tested and came back with zero faults. Then laid out in our 5,500 square foot workshop as a trial run with an engineer to 3D scan to be sure we were within our tolerances. Items were then sent off to be galvanised, shotblasted and painted in accordance with Network Rails paint specification N9. Certificate of conformity and a paint report was provided to ensure criteria were met.

Installation was carried out on line blocks on midweek nights. There was a very tight schedule as the transverse beams needed to be installed prior to the 52 hour possession in week 07. We wanted to focus all our efforts on the over plating that needed to be welded into position during the possession as this gave us the plenty of uninterrupted time on track from RRV movements and engineering trains. additional weld testing to the over plating was carried out and came back with zero faults.
