Probe signals delay for Tesco at Gerrards Cross

A FURTHER ground investigation at the troubled site of a proposed Tesco supermarket at Gerrards Cross has been announced just three months after Costain completed a major review of the scheme, it emerged last month.

The development in Buckinghamshire has been in limbo since a rail tunnel collapsed underneath the site last year. Progress on the development will be delayed by a further three months. Tesco said in a statement last month: 'As part of the ongoing investigation into the Gerrards Cross tunnel collapse, Costain is required to carry out further geotechnical investigations within the bounds of the Gerrards Cross construction site. This is to confirm the engineering properties of the fill material under the store.' Post-collapse investigations were immediately carried out by tunnel contractor Jackson. The new work will take 11 weeks.

The project has been in limbo since June 2005 after a major rail accident was avoided when a 30m section of new rail tunnel collapsed onto the line. Jackson was in the process of creating a 320m stretch of tunnel in a railway cutting at Gerrards Cross.

The aim was to build up ground over the newly created tunnel to create the supermarket site. Costain replaced Jackson on the job in March 2006.

Network Rail confirmed that it had yet to receive revised plans from Tesco for work to restart, and that it would be scrutinising them carefully when it did. 'We are not going to let any construction work go ahead on site until we are completely happy with what is planned, ' said a spokesman.
