Pile Driving Record
Why Automated Pile Driving Record is Preferred?
It’s a common practice to prepare a piling record for each driven pile. Information provided in a pile driving record is the basis for the evaluation and acceptance of the non-tested piles. So they could be of great importance. But we have all seen manually filled driving records that are not well prepared or look dirty and inaccurate. In addition, instructing a worker to measure pile Set and temporary compression (TC) manually, while standing under a working hammer, could be quite dangerous. Furthermore, human errors in the process of measurements and recording of the information make manual records less reliable. The quality, safety, accuracy, and presentation of pile driving records could highly improve if the process is automated using available technologies. Also, the driving data could be easily transferred to a computer device for further processing, removing the extra time, effort, and errors that manual entry causes. Depending on the local practice and desired level of quality assurance, CQA offers two solutions for preparing automated pile driving records: SAX-Q and PDM³.
PDM³
PDM³ is designed to provide blow count, Set per blow, and Temporary compression for the whole driving length of the pile. Project information, hammer specifications, and pile details are entered manually before the piling process starts. PDM³ sits at a 5-25m distance away from the pile and continuously reads the sticker targets which are previously attached to it while the pile further penetrates into the ground. At the end of driving, a full driving report is automatically generated. Since the PDM³ measures both Set and TC, it allows for a reliable calculation of capacity through the modified Heily formula.

SAX-Q
For the projects in which pile acceptance is based on the Set per blow (blow counts), SAX-Q could be used to automate pile driving records. This PDI equipment includes a sound detector which enables it to automatically record blow counts and convert them to the BPM and Set. By entering project details and penetration information, SAX-Q creates a full driving log for each pile which could be saved and modified later. Visit the SAX-Q product page for more information.
