The sheet piles were installed using a Telescopic Leader Rig and the Kowan WP150 Still Worker with the piles pitched with the Appleton Piling Ltd Logicrane 55.38 Telescopic Crawler Crane. Removal of the temporary framing and extraction of the sheet piles, using the Kowan WP150 Still Worker, will commence in February 2011.

Noise and vibration were kept to an absolute minimum using the Kowan WP150 Still Workers when piling on the site directly adjacent to the Westminster Council Offices on Victoria Street, London and the Korean Embassy on Spenser Street, London. The sheet piles were installed through the sands and gravels to toe into the clay strata approximately 13m below ground level.
