SUPERMARKET GIANT Tesco has still to submit revised plans for its troubled Gerrards Cross store to Network Rail for approval - almost three months after its contractor Costain concluded its review of the project.
Tesco has now requested contractor Costain carry out further investigations on the ground conditions at the site.
In a statement posted at the site, the supermarket said: '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 material under the store.' Geotechnical investigations in the immediate aftermath of the collapse were carried out by Jackson. The new work will take 11 weeks.
The project has been in limbo since June last year, after a major rail accident was narrowly avoided when a 30m section of new tunnel collapsed onto the live railway line (NCE 7 July 2005).
At the time, contractor Jackson was creating a 320m length of tunnel over the railway.
The aim was to build up the ground over the tunnel to create the site for the supermarket.
Costain replaced Jackson on the job in March.
Network Rail conrmed that it had yet to receive plans from Tesco for work to recommence, and that it would be scrutinising them carefully when it did.
'We are not going to let any construction work to go ahead on site until we are completely happy with what is planned, ' said a spokesman.
