Large Capacity Screw Pile Installation for Industrial Project in the South East
Industrial buildings often require fast-track foundation solutions with high load capacity. Preformed Substructures Ltd installed large capacity screw piles for a new steel-framed industrial building in the South East.
Project Summary
The client required rapid installation of piled foundations capable of supporting a multi-storey steel frame structure but wanted to save the time and cost of having to install a piling mat and waiting for concrete to cure. Our high-capacity helical screw piles provided the solution; by using a large excavator mounted piling equipment we can excavate to formation and install piles at the same time.
The piles do not require curing time and can be set at the correct design height during installation so the follow on works in the construction sequence can commence earlier – in this case saving over 22 days on the construction programme and 66% embodied carbon compared to concrete piling.
Step-by-Step Project Delivery
- 1
Ground Investigation Review
The site contained variable ground including fill, clay and dense sand.
- 2
Pile Design
We designed a screw pile system with:
- Large diameter shafts
- Multiple helix configurations
- Enhanced corrosion protection
- Full load testing plan
- 3
Site Setting Out
Pile locations were surveyed and marked using GPS systems.
- 4
Screw Pile Installation
High-torque heads mounted to an excavator installed piles quickly with real-time torque monitoring confirming structural performance.
- 5
Load Testing
Static tests verified that all piles exceeded required loads.
- 6
Connection to Steelwork
Piles were installed down to the correct design level fitted with their structural connection heads ready for incorporation into the reinforced concrete ground floor slab.
Results
The client benefited from fast, clean installation and immediate load capacity, helping them meet a tight construction programme.
