The almost 20-month contract will see M&E work undertaken on buildings located at either end of two green tunnels within the EKFB section of the HS2 works in the West Midlands.

The tunnels, located at Chipping Warden & Greatworth, are two of five green tunnels in Northamptonshire, stretching 2.5 kilometres and 2.7 kilometres respectively.

They are shallower tunnels that will be finished with trees, plants, and shrubs on top – helping them blend into the natural landscape that is being built. 

There are a total of four portal buildings, which along with their compound, houses the mechanical, public health, fire and electrical equipment and provide necessary services for the Green Tunnel.
