Sainsbury's Welwyn Garden City

Sainsbury's are expanding their superstore at Welwyn Garden City. Appleton Piling Ltd completed the installation of the temporary excavation support in January 2011 working for contractor AD Bly Ltd. Appleton Piling Ltd designed the sheet piles and framing system to allow excavation to a maximum of 6.4m below the existing ground level.

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.

Appleton Piling Ltd have recently completed the temporary sheet piling to the proposed basement structure for Sir Robert McAlpine. A total number of 397, 16m and 17m long, SX27 sheet piles, were installed using two Kowan WP150 Still Workers.

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.
