Our General Piling division was appointed to deliver foundation works for the A417 Missing Link, a major highways project improving connectivity through the Cotswolds. The scheme creates a safer, more resilient road between Brockworth and Cowley, while enhancing the surrounding National Landscape.
Project Background
- Appointed by Kier
- The scope of work comprised the installation of 22No. 750/650mm piles and 30No. 1180/1050mm piles, reaching depths of up to 24m for the bridge abutments and wing walls of the new road.
Challenges
The works involved demanding ground conditions, with piles installed to depths of up to 24m. Achieving the required design toe levels while maintaining robust quality control was critical to the success of the project.
By working closely with Kier, Tony Gee, and National Highways, we identified potential risks early and implemented solutions quickly, ensuring progress was maintained without compromising safety or quality.
Van Elle Solutions
To overcome the challenges encountered, rotary piling using the Soilmec SR95 was selected as the most effective solution. A total of 52No. piles were installed, comprising 22No. 750/650mm piles and 30No. 1180/1050mm piles, reaching depths of up to 24m for the bridge abutments and wing walls. Full-length reinforcement cages were utilised throughout, ensuring structural integrity and durability.
The SR95 in rotary configuration provided the flexibility to achieve the required design toe levels, while maintaining robust quality control across the piling process. This approach ensured progress was maintained and delivered a high-quality outcome across a technically challenging scheme.
