RADISSON HOTEL, WATERFRONT

 

The 195 room Radisson SAS Waterfront Hotel,  Jersey opened 2007  is constructed close to the popular waterfront promenade and within close proximity of the financial district and town centre. 

The site was reclaimed from the sea about 10 years ago. Amplus designed and installed the piles. The six storey hotel is supported on nearly 300nr driven pre-cast concrete piles. The 275mm square piles were manufactured in England using a concrete mix DS-3 suitable for the harsh ground conditions. The 11m - 13m long piles were shipped to Jersey and driven in with a Junttan PM16 crawler mounted rig and a 3 tonne hammer to a safe working load of 750kN.

In addition, Amplus drilled 30nr mini-piles successfully  through the rubble sea wall abuttung the site. The 250mm diameter permanently cased piles were installed using a TD610 rig and rotary percussive pneumatic drilling methods.

Amplus completed the piling on programme in 27 days in 2006.
