Deciding to scan concrete for your project was a smart decision for many reasons. It saves you time by knowing where to exactly cut, drill, or core. It saves money by preventing damages. And, most importantly, it keeps your project safe. Now that you want to move forward with our scanning services, here is what you should expect.
One of our expertly trained GPR analysts will arrive at the jobsite. Before they start scanning, they will meet with you to discuss the areas that you want scanned. You would need to provide a layout for the analyst to scan. After this, the analyst is ready to scan. GPR (Ground Penetrating Radar) is safe to use during regular business hours. This means that any trades on the jobsite can continue with their job while the scanning takes place.
The analyst might use different types of equipment depending on the job itself. While the scan takes place, the data shows up in real time. Our analysts can interpret the data and from there he/she can mark any objects directly on the concrete surface with tape, chalk, keel, or markers (as pictured above). Then, the analyst would communicate their findings with you.
Sometimes, the proposed layouts are clear and ready for coring or drilling. Some other times, the analyst finds post tension cable, rebar, or other objects in the area where the coring or drilling is proposed. If this is the case for your project, you can propose a second layout location. The analyst will then proceed to scan that area to make sure that it is clear and safe.
All results will be marked directly on the surface and scanning report will be provided. After the scanning, a summarized written field report of the findings will be provided you. Our report includes a detailed description of the scope of work, inspection methods, and equipment used. Of course, it also includes visuals such as site locations, images of data, and site photos. With this piece of information, in addition to your field markings, you can make decisions as to where to cut, core, or drill. This report take additional time and will be completed off-site and will be emailed to you.
