Checks for hidden well delay CTRL at Stratford

CHANNEL TUNNEL Rail Link (CTRL) engineers were this week checking to see whether an uncharted well is lying in the path of one of its tunnel boring machines (TBM) at Stratford.

The machine has been out of action after triggering a ground failure at Lavender Street (NCE 13 February).

A CTRL spokesman said this week that engineers had been aware that there was an old water pump located in Water Lane, which lies directly ahead of the immobile TBM.

Tunnelling has been on hold along the route while CTRL project manager Rail Link Engineering (RLE) continues investigations into the Lavender Street ground collapse.

More detailed investigations are now scheduled to take place.

If there is a well it will need to be stabilised before tunnelling can restart.

An RLE source said last Thursday that tunnelling was unlikely to start for at least two weeks.

Meanwhile the Health & Safety Executive was this week investigating Stratford residents' claims that project managers and Newham Borough Council failed to heed warnings about several old wells near the tunnel route.
