In the latest phase of work on the Staffordshire Alliance Project, a key scheme in the West Coast Main Line Improvements Programme, VolkerGround Engineering is constructing the piled foundations for the Greenfield Overhead Line Foundations.
Chris Thomas, director of VolkerGround Engineering, said: “The fact that we are able to offer different piling systems to cope with the changing rock head levels through the site has been a real benefit to the project team.
“Our work is really important because it will make way for the arrival of a specialist track laying plant. We’re excited to be once again working on this project.”
The contract will comprise of a combination of 750mm and 1000mm diameter Continuous Flight Auger (CFA) bored cast in place concrete piles, which will go to a 5m depth, and 610mm driven steel tubular piles which are 6m long.
The different pile types are a reflection of the variation of the ground conditions over this greenfield section of the Main Line alignment.
The construction is taking place west of the village of Norton Bridge in Staffordshire.
