EKFB – consisting of Eiffage, Kier, Ferrovial and Bam Nuttall – said it had moved 20M.m3 of material on the mammoth project.
The consortium is delivering 80km of track as part of the London-to-Birmingham leg of the £100bn rapid rail link.
A four-year earthworks programme is well underway, although a total of 50M.m3 is expected to be shifted before it completes.
Using 800 items of plant and more than 1,000 skilled operatives, the huge task will make way for a network of 33 cuttings and 49 embankments designed to blend the high speed railway into its surrounding landscape.
EKFB is delivering civil engineering works from the
Chiltern tunnels in Buckinghamshire to
Long Itchington Wood in Warwickshire. This will include 15 viaducts, 6.9km of green tunnels and 81 bridges.
