Pennine Vibropiling has been appointed as a partnering specialist contractor for ground improvement at J Sainsbury Developments'new £23M Castle Vale Shopping complex near Birmingham.
The firm, working with construction manager Schal International Management, groundworks contractor PJ Carey and structural contractor John Allen Associates, says it was asked to contribute ideas to benefit the construction programme and reduce costs.
One such idea was to use vibro stone column techniques to improve the ground beneath the floor slab and some bases.
Another was the re-use of crushed demolition material to build a 200mm thick working carpet, capable of withstanding loads of up to 15kN/m2, across the 5,500m
2site, saving material costs.
The site was previously occupied by a 1960s residential tower block and shopping precinct.
