Ground engineering is a specialised earthworks application that requires advanced solutions that can meet a broad spectrum of customers’ requirements. James Fisher Prolec offers off-the-shelf packages and customised solutions for a variety of drilling and piling equipment, including continuous flight auger (CFA), driven piles and rapid impact compaction (RIC), proving to be exceptionally valuable in marine piling applications.
Drilling and piling guidance is generally offered as either 2D or 3D, where a digital terrain map (DTM) is uploaded to the cab of the drilling or piling rig. This DTM contains all the information relating to pile X and Y coordinate positions and in some cases Z for elevation. The system uses GNSS positioning equipment in combination with James Fisher Prolec's angle sensors that can be mounted on the mast of the rig to provide an accurate measurement of pitch and roll, which relates to the verticality or slope of the pile or bore hole. Measuring the verticality allows extremely tight vertical and slope tolerances to be maintained.
- Reduced site setting out
No need to mark each position, so no requirement for additional personnel to guide the operator to the next position. This increases productivity and safety significantly
Each completed pile or drill position is fully annotated, including positional coordinates with a time and date stamp. Extracted data can be used in conjunction with "as-built" data.
