A general contractor reached out to Ground Penetrating Radar Systems (GPRS), Philadelphia office. The scope of work for this project was to detect underground utilities in an area approximately 100’ in length. The primary concern was the location of a 6” water main which was coming out of the water pit and going right in the area of the proposed excavation area. The location of this water line was critical for the engineer to plan the location of the proposed concrete pad that was looking to be installed. This project took place at a facility in Chester, PA.
Upon arrival, GPRS Project Manager Igor Skuratovsky performed a site walk with the on the site personnel. After the site walk concluded, Igor believed the locate would be pretty straight forward. The main concern was to locate the water line, as well as any other unknown pipes that may be in the area.
The first mode of action that GPRS took, was to utilize the EM locator. Igor used the direct connection to clamp on to the pipe inside the building using the transmitter. He then traced the water line outside using the EM receiver. To ensure he was locating the correct line, he located the pipe all the way back to the water pit. Since there were no other surface features in the area, Igor passively used the EM pipe locator to search for any other unknown pipes. He then used both the transmitter and receiver. No additional pipes in the proposed excavation area were found. The next step GPRS took was to scan, using a 400MHz ground penetrating radar antenna. The 400MHz antenna is designed to locate underground utilities and other subsurface anomalies. Using this technology, GPRS was able to identify the approximate depth of the water line which was previously detected using the EM locator. The 400 MHz antenna is another tool that is utilized to locate other underground utilities that may not have any surface features. All of the findings were marked according to the painted color code which has been established by 811. Lastly, all of the utility line’s locations were collected using our GEODE (GPS) device. Collecting these locations, allows GPRS to create deliverables such as non-survey grade, Google Earth overlays or CAD drawings. Not only is this important to your current project, these drawings can be kept as records for future use.
All GPRS Project Managers are highly skilled and trained in the field of concrete scanning and utility locating. However, it does not stop there, as we have helped numerous clients identify underground storage tanks (USTs), footings, and identify voids on site.
