Challenge: Limited Access and Need for Piled Foundation Solutions
GeoEnviro Solutions Ltd was contracted by a telecommunications infrastructure company to install AB Chance helical screw piles for the installation of phone masts at multiple sites across the UK. While many of these sites were suitable for standard pad foundations, certain locations required a piled solution due to site-specific ground conditions.
The primary challenges included:
- Site Accessibility: Many locations presented tight access around services, making traditional foundation solutions difficult to implement.
- Need for a Custom Foundation Solution: Specific sites required a tailored piling solution to support the installation of phone masts.
- Ground Investigation for Optimal Pile Placement: Comprehensive ground investigations were necessary to determine the suitability of screw piles at each site and to model the correct size and depth of the piles.
GeoEnviro Solutions needed to provide a foundation solution that could be installed quickly and efficiently, with minimal ground disturbance.
Solution: Installation of AB Chance Helical Screw Piles
GeoEnviro Solutions Ltd developed and implemented a piling solution using AB Chance helical screw piles. This approach offered several benefits for the client’s telecommunications infrastructure needs:
- Ground Investigation and Custom Pile Design: Ground investigations were carried out at each site to assess the soil conditions and determine whether screw piles were the best solution. The GeoEnviro team designed a custom specification for the size and depth of the piles, and designed an adjustable grillage to support the phone masts.
- Efficient Installation in Tight Spaces: The screw piles could be installed in sites with restricted access, making them ideal for locations where traditional foundation methods were impractical.
- Quick and Minimal-Disturbance Installation: Helical screw piles were installed quickly and with minimal ground disturbance, reducing installation time and saving costs for the client.
- SS5 AB Chance Screw Piles: These piles were installed to depths of 6 to 20 meters below ground level (mbgl), with a torque rating of 5,700 lb/ft and a holding capacity of up to 10,000 tonnes.. This ensured strong and stable foundations for the phone masts.
The use of helical screw piles allowed GeoEnviro Solutions to deliver a reliable and efficient foundation system, even in challenging site conditions.
Result: Efficient Installation and Reduced Costs for Telecommunications Projects
The use of AB Chance helical screw piles provided several key advantages for the telecommunications infrastructure project:
- Optimized Foundation Design: GeoEnviro’s ground investigations and custom pile modelling ensured that each site had the appropriate foundation solution based on specific ground conditions.
- Time and Cost Savings: The rapid and efficient installation of screw piles minimised project timelines and reduced costs for the client, thanks to the reduced need for extensive excavation or heavy equipment.
- Versatile and Scalable Solution: The helical screw piles, thanks to their varied applications, can be easily adapted for future expansion or additional infrastructure installations. Their ability to support not just telecommunications masts but also to be used for underpinning, slope stabilization, and other projects makes them a flexible and future-proof solution for ongoing infrastructure needs.
GeoEnviro Solutions Ltd’s expertise in helical screw pile installation and ground investigation allowed for the successful execution of this nationwide project, providing a long-lasting foundation system for the client’s infrastructure.
