Hilo Concrete Scanning Projects that Penhall Technologies Has Worked On

Our Hawaii field office received a request for Ground Penetrating Radar (GPR) scanning on the side of a bridge. When our two analysts arrived on site, the contractor explained that he wanted a GPR scan of 14 3’x3’ areas along the side of a bridge. The purpose of the scan was so that he can safely drill 5” anchors to mount a new pipe. This is when the expertise of our GPR analyst comes in. He can scan the locations to analyze the data to see if the contractor was clear from rebar and any other embedded objects for the pipe that will be mounted.
Since the locations being scanned were located on the side of the bridge, the analysts completed a standard risk assessment previous to arriving at the location. At Penhall Technologies, we take safety very seriously. The risk assessment ensures the safety of our analysts. This consists of making sure that they wear the correct fall protection equipment that is required for jobs like this. Once safety measures were all in place, the analysts proceeded to scan each location while being 12’ above water. After each location was scanned, rebar was found in the concrete slab. The analysts concluded that certain layouts proposed by the contractor wouldn’t be recommended for drilling, as they were along rebar. The analysts properly marked the layouts for the client, and the analysts advised the client to stay clear from their marks. The contractor was more than satisfied and confident with drilling his anchors after observing the analysts’ communication and interpretation of the data to him. Our Hawaii field office in Hilo will ensure that you have the right data and tools. Our Analysts are expertly trained to complete your mission safely and on time.
