The success of its Housedeck and Comdeck proprietary foundation systems has led Abbey Pynford House Foundations to buy three new piling rigs in the past 12 months, and it expects to increase its fleet more during the next six months.
Two of the rigs are Casagrande B125/B135 mid-range CFA/bored piling rigs. 'Much of our current workload is generated from the volume housebuilding sector, which expects high production outputs from foundation specialists, ' explains Abbey Pynford's commercial director Nick Hodder. 'Both Casagrande rigs have production outputs that exceed 500m per day on several projects.' The third machine is a Klemm 307, weighing 13t, catering for limited access and restricted headroom contracts.
The Housedeck Foundation System has been used for a variety of recent housing schemes in the Home Counties, including a development of 71 units in Chipping Ongar, Essex for Bryant Homes.
Here, Abbey Pynford's design solution consisted of 1,340 CFA piles - all 300mm in diameter - installed to depths of between 6m and 10m, topped with 4,677m 2 suspended reinforced concrete Housedeck slabs.
The individual Housedeck slabs varied in size from 75m 2 to 200m 2. The Comdeck system was recently used for the construction of a 90-bed, six-storey Travelodge hotel in Harlow, Essex. The building sits on 152 CFA piles, 300mm in diameter and topped with 800m 2 of reinforced concrete Comdeck varying in depth from 225mm to 325mm.
Abbey Pynford completed the foundation work in eight weeks - two weeks ahead of schedule.
