Driving Innovation: Why it Works
- Less equipment
needed
- Drastically reduces set
up times
- Only two to three crew
members required
- Safety, environmental,
landowner, and cost benefits

Driving Results: Costs
- Initial indications show Solo-Driver is poised to cut costs
significantly compared to traditional installation methods
– Reduced equipment costs – Reduced labor costs – Reduced project risk dollars due to smaller construction window

Driving Results: Soil Type and Access
- Solo-Driver is more efficient than other methods, even when
navigating challenges that can slow any foundation installation project
– SOIL TYPE
- FAVORABLE: Sandy or loose soil 18-23 per day
- LESS FAVORABLE: Higher clay content 6-8 per day
- UNFAVORABLE: Rocks and cobbles
– ACCESS
- One unloading/reloading 15-23 per day
- Multiple unloadings/reloadings 7-9 per day
