Network Rail required urgent and long overdue repairs to the 5N0 Platforms that accommodate trains to and from London and Brighton via Gatwick airport. The station also manages in excess of 25N0 sidings that berth trains overnight. Repairs included canopy and platform drainage, replacement of 1200m of GTech copers and resurfacing throughout. Braybrook completed the design of track alignment and X&Y Gauge for the platforms.
The contract was administered via a NR9 Design and Build form. Given the restriction of access the trackside work was intricately planned around Line Blockages and Possessions. Close liaison with the station staff and TOC management was essential. In order to maximise the efficiency of work in small windows a Poly bridge was utilized to transfer labour, plant and materials between platforms.
Continual movement of freight and passenger trains disrupted the work pattern on a daily basis however, a fluid programme with contingency work activities enabled earned value to be achieved. Gatwick Express train movement was prioritised and frequent timetable changes meant work breakdown structures had to be regularly re-planned and briefed to the work party.
Re surfaced platforms with new slit channel drainage and anti-slip copers were complemented by repaired brickwork and canopy improvement across the whole station. The works were carried out around a busy schedule of train and passenger movement.
