CLRL studies ground conditions


Cross London Rail Links (CLRL) has been digging boreholes along the Crossrail Line 1 preferred route to examine the ground conditions that will be encountered by Crossrail tunnels.
Engineers from Norwest Holst are investigating the quality of the ground to assist in compiling a geological model in preparation for the construction of a tunnel running from the Isle of Dogs to Custom House.
"The conditions at the tunnel's depth will help to design the tunnel boring machines to minimise ground settlement," said Bernard Gambrill, CLRL's head of public affairs.
Although Crossrail is awaiting an announcement from the government concerning the next stage of the project, advance development work still has to be carried out.
"The Crossrail development work has to be conducted to enable the project to be constructed on schedule," he said.
