Walker Construction (UK) Limited was commissioned to carry out the demolition of the existing platforms 1 to 8, then the removal of all running rails to make way for the construction and lengthening of all eight platforms. All the platforms required to be reconfigured to allow the bottle neck shape of Waterloo Station to be maximised to provide more room for the required extensions.
To allow for the reconfiguration and laying of the permanent way, Platforms 1 & 2 and Platforms 3 & 4 were extended to accommodate 10 Car trains. Platforms 5 & 6 were reduced in width to accommodate the platform extensions and Platforms 7 & 8 were increased in width for 37 metres with a new ramp.
There were some additional works to this project which included the laying of platform surface; installation of stick on tactiles; painting of the existing platform coping noses white and mind the gap; Installation of Platforms 1 & 2 and Platforms 3 & 4 decks and supporting beams for new peak hour subway stairs; casting of C/E platform end details.
This task was undertaken over 21 days and night working 24/7 and was planned over the 12 weeks before the blockade.
This project was challenging due to the number of disciplines working at the same time within a small area while all trying to keep to programme.
