Roger Bullivant Limited has collaborated with Persimmon Homes East Scotland on a multi-phase housing development project at Pirnhall Road, Bannockburn, Stirling.

Utilising the innovative RBeam foundation system, capable of pairing with any pile type, ensures this project can adapt to diverse ground conditions, highlighting RBL's commitment to versatile and reliable construction solutions.

This development will encompass the construction of 104 houses and 2 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. Shallow rock presence on selected plots, less than 3 meters 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 precast RBeam system's unique capability to pair with any type of pile makes it an ideal solution for the diverse ground conditions encountered at the development site.

The initial phase will see the installation of just over 880 linear meters of RBeam, out of a total of 3200 linear meters planned for the entire site. This first phase, completed in just eight weeks, showcases our efficiency and expertise in foundation engineering.

Mark McAllister, Foundation Systems Discipline Manager for RBL's Scotland Region, stated: "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."

RBL is dedicated to delivering high-quality foundation solutions that meet the specific needs of each project while maintaining its industrialised approach to foundation manufacture taking advantage of standardised parts and factory quality. The work on this development not only highlights our technical capabilities but also our adaptability to challenging ground conditions. The innovative use of RBeam with both steel and precast piles ensures stable, reliable foundations, regardless of the conditions.
