Piccadilly Line


Last week's story about settlement of the Piccadilly Line tunnel at Heathrow airport said that piles for a new road tunnel had been inserted by Miller Group. In fact the piles were inserted for client BAA by subcontractor Bachy. Bachy was working for Laing, which has the contract for the tunnel approaches. Morgan Sindall subsidiary Miller Tunnelling has the main tunnelling contract.

The article also said that the piles were sunk around the new tunnel. In fact the piles were sunk around the Piccadilly Line tunnel, ahead of new tunnel construction. BAA and London Underground anticipated settlement on the Piccadilly Line tunnel and have been monitoring it ahead of and during approach ramp construction.
