Sevenoaks Tunnel Drainage

Started:December 2015
Completed:Ongoing
Client:BAM Nuttall
Location:Sevenoaks, Kent
Value:TBC
Project Overview

BAM Nuttall were the successful principal contractor to be awarded this project to improve the track drainage within the 2 mile stretch of Sevenoaks Tunnel. The current drainage previously installed within the tunnel confines is failing, which in turn is causing major problems with the line speed throughout this part of the South Eastern main line. The Sevenoaks tunnel is a vital link for commuters in the route to Hastings from London. The conditions within this tunnel are extremely treacherous, with masses of water ingress from both underfoot and also from above, making the delivery of this project an even greater challenge.

Key Deliverables

The scope of works include:

  • Assisting in the delivery of the 6ft track drainage

  • Installation of new catch pits

  • Breaking out of existing culverts

  • Changing of sleepers

  • Ballast packing behind Tamper

  • Rail change every 2 years


Staffing Specifications

Civil Rail Solutions were engaged by the appointed principal contractor BAM Nuttall in September 2015 to provide skill track drainage staff to carry out drainage renewal works throughout this long & extremely wet tunnel. BAM Nuttall were impressed by not only CRS’ track record of delivering track drainage renewals, but also in their collaborative working with all of their clients. After initial discussions back in September 2015, CRS were engaged early in the planning process to supply staff to deliver the initial Christmas possession & subsequent possessions thereafter.

Civil Rail Solutions are providing the following staff throughout ongoing key possessions:

  • PTS Skilled groundworker’s

  • PTS Drainage staff

  • PTS Foreman

  • PTS Supervisors

  • PTS Trackman


Reference

"A big thank you to you and your lads for all of your efforts over Xmas. In the end we successfully installed 142m of 6ft drainage and handed back on time with no issues – A fantastic achievement given the problems encountered.  Please could you pass on our gratitude to your lads and let them know how impressed we were. I know everyone had to go above and beyond to turn it around and we couldn’t have done it without them. Superb"
