UK GEOTECHNICAL contractor Pennine has teamed up with US contractor Nicholson Construction on a site improvement contract for a 12,700m 2DIY store in Berlin, Maryland.
Geology of the site is sands, silts and clays with pockets of organic material. About 2500 stone columns were installed to enhance the bearing capacity and control settlements for the foundations and the heavily loaded floor slab.
Pennine provided two sets of top feed vibro equipment and a foreman to advise Nicholson, which supplied the cranes and operatives and sourced the raw materials.
Nicholson is keeping the equipment for future projects.
The design for the Berlin scheme was carried out at Pennine's headquarters in Bacup, Lancashire.
