ROGER Bullivant Limited’s innovative RBeam foundation system is to be utilised on Persimmon Homes East Scotland’s multi-phase housing development in Bannockburn.
The foundation engineering firm explained that the system is capable of pairing with pile type, which will ensure the build on Pirnhall Road can adapt to diverse ground conditions.
The development will comprise 104 houses and two blocks of flats, with the first phase supporting 19 detached and semi-detached homes. The project will utilise approximately 840 piles across its entirety, with the first phase requiring a combination of 140mm driven steel tubular piles and 200mm driven precast concrete piles.
The combination of steel and precast piles was chosen based on the specific geological characteristics of the site. Roger Bullivant explained that shallow rock is present on selected plots, that is less than three metres deep, necessitates the use of steel piles to efficiently drive into the shallow rock strata, while precast piles are utilised where deeper penetration into the made ground overlying soft to firm gravelly clay is required. This ensures optimal stability and performance of the foundation system across varying ground conditions, the firm added.
The initial phase will see the installation of just over 880 linear metres of RBeam, out of a total of 3,200 linear metres planned for the entire site.
Mark McAllister, foundation systems discipline manager for Roger Bullivant in Scotland, said, “The flexibility of the RBeam system allows us to effectively address the unique ground conditions at the Stirling site. By pairing the RBeam with both steel and precast piles, we can ensure stable and reliable foundations for the diverse range of homes being constructed.”
