Roger Bullivant Limited (RBL) is proud to announce the successful delivery of its in-house designed and manufactured innovative precast foundation system for a major residential development by Dundas in Bishopton, Scotland. This 46-unit development showcases RBL’s sustainable and cost-effective value engineered solutions, using low carbon concrete to minimise environmental impact.
The affordable homes section of the development features a mix of semi-detached and terraced homes, all supported by RBL’s precast piling and beam system. Over 500 No. Driven Precast Concrete Piles as well as 1,500 linear meters of RBeam, RBL’s precast ground beam system, were installed to provide a robust and efficient foundation solution. Piles were driven to design depths of 16m and 20m to accommodate challenging ground conditions.
Ground conditions consist of very soft to soft silts and clays (Linwood Paisley Formation) extending to depths of between 16.50mbgl and 22.00mbgl at which point stiff clays are encountered. Localised bands of silty sands were encountered at depths between 14.00-16.00mbgl across the site. These soils are typical of the Bishopton development area. Driven precast piling is ideally suited to these ground conditions, offering a quick and efficient method of pile installation.
This system not only ensures structural integrity but also provides a cost-effective alternative to traditional trench fill foundation solutions. RBL’s in-house design expertise ensures that the system is tailored to the unique requirements of every project, optimising efficiency and reducing material waste. By utilising standardised precast components, manufactured and stored at RBL’s headquarters, the process minimises waste on site, thereby reducing lorry movements, and keeps costs under control.
“We are pleased to work with Dundas to deliver a high-quality, sustainable foundation solution for this residential development,” said Gavin Hay, Scotland Area Manager at Roger Bullivant Limited. “Our precast system not only provides a reliable foundation but also supports the industry’s drive towards lower-carbon construction methods.”
RBL’s Scotland team played a key role in the planning and execution of this project, ensuring seamless delivery and installation. This project highlights RBL’s expertise in foundation systems and reinforces the company’s position as a leader in sustainable foundation engineering.
