CSI had undertaken some extensive training with the Provider, but there is nothing like working in the field to hone the skills and put that training to the test. This case was no different!
We ran all of our data collection and analysis methodologies through the Manufacturer and Provider, as is our QA when working with new equipment (we were given the tick of approval). CSI always seeks QA and even back-up on-site when using new gear; as there is nothing like the experience of years of professional and accurate use with a specific device, to ensure accurate results. As our readers are well aware; we also conduct plenty of our own R & D in-house once any training modules for new devices are completed.
All scanning equipment has its own idiosynchrasies; so while CSI are leaders in the field of GPR scanning, there are always experts around the world (particularly those who manufacture the gear) who can be sought for extra help. We like this method as it saves “reinventing the wheel” using much time and resource – when questions can be answered quickly and cost effectively by existing experts.
The QA to be established in this case was the level of cover over the reinforcing steel in one section of the bridge; the results could then be extrapolated out to be representative of the remainder of the bridge. It seemed very sensible to get this QA done before the bridge comes into use.
We do wish the Managers of the Project all the best with any remediation that is deemed necessary.
If you have any questions on this project or would like to discuss any NDT requirements you may have please contact the CSI team.
