Geotechnical contractor Bauer is carrying out piling works on the iconic Battersea Power Station in London.
Site work began in February with test drilling before the main piling work got underway in June. Some 600 foundation piles with a diameter of 2m are being installed at depths of up to 60m. A further 900 piles will be installed for a secant pile wall at the site, which is in the process of being converted into residential, office and commercial space.
The work is taking place next to or underneath existing buildings, which means the heavy-duty rotary drilling rigs are operating with limited space and access.
“It is both an extremely interesting and challenging project,” said Bauer Technologies managing director Martin Blower.
Before the work could begin, significant concrete obstructions had to be removed, and the clayey London subsoil presented a deep scour feature in the area where work was going on.
Bauer’s piling work is due to continue until the middle of 2017.
