Piling and diaphragm walling for the Tottenham Court Road western ticket hall site is now complete.
Balfour Beatty/Morgan/Vinci JV (BBMV) constructed 39 piles which descend into the ground up to 46m, to form the foundations of the station structure. Following this they created the diaphragm walling which forms the perimeter of the new ticket hall box.
The works have not been without their challenges and the team have had to address various issues such as very tight working space, utilities constraints and below ground obstacles. The installation of piles and diaphragm walls had to be completed within strict time periods, requiring some round the clock working.
Extensive engagement with the local authority and community helped to ensure that the programme of works minimised disruption to neighbours.
The site has been handed over to the western tunnels contractors BAM Ferrovial Kier JV (BFK) to excavate and prepare for the arrival of the tunnel boring machines.
