Pile Positioning

Testimonial from Week’s: “The results of ease of use, accuracy

and productivity of the system has been excellent with no survey related delay for pile positioning, especially when considering the equipment is working in the shadows of the crane, template spuds and piles up to 104 feet long”.

Atkinson Construction – Maine, USA Piling for Land Reclamation 4 barge systems installed

Testimonial from Atkinson’s: “The Trimble piling system is ideally suited to our

project as it provides us with the capability of working 24 hours a day. In our harsh environment we use the system to monitor the position of the barge in real-time, especially when moving onto location. This can be a tricky operation as we can experience currents in the river up to 8 knots. We also monitor the position of the barge while on location when the tide changes direction. The system provides us with the station and offset for each pile placement in real-time.”
