Prior to excavating and trenching for over 100 wind turbine foundations, 17 miles of access roads and 51 miles of collection lines, a major wind energy contractor subcontracted Ground Penetrating Radar Systems, LLC to locate active and abandoned underground utilities throughout the entire project area. The contractor knew of multiple oil and gas pipelines running throughout the project and needed GPRS to confirm the known utilities and identify any unknown or abandoned utilities. After working with GPRS on dozens of other projects, they knew exactly who to call to meet their needs on this project. After mobilizing to the jobsite, the Ground Penetrating Radar Systems’ team was able to locate and confirm multiple pipelines within the excavation areas on just the first day on site. While scanning one of the wind turbine foundation areas, GPRS marked an unknown buried utility that ran directly through the excavation area. This utility was not marked on any historical map nor was it known by the contractor ahead of time. Using Electromagnetic Line Locating and GPR technologies, they were also able to trace out the utility throughout the entire area of concern. Upon reaching the end of the project boundary, the utility was exposed above ground and turned out to be an abandoned gas pipeline. The contractor was able to visually see all of the findings due to the easy to interpret flagging and staking system used by GPRS to mark all their findings. After the area was scanned, the gas pipeline location was collected via GPS and exported to a daily Google Earth KMZ file for the client to use in the future, holding a convenient and precise permanent record. A post scan walkthrough was also conducted with the GPRS team and the client to explain all our findings and answer any questions the client may have. After reviewing the results, the client was grateful that GPRS was able to identify the previously unknown utility. The contractor went back to the drawing board and made an alternate wind turbine foundation location based on the findings, avoiding the buried pipeline entirely. During this process, the GPRS Project Manager on site provided clear and concise communication with the client on all site limitations and findings. Using the information provided, the client was able to make informed decisions, keeping their project on time, under budget, and most importantly, safe. Safety is top priority with GPRS; all necessary personal protective equipment (“PPE”) is utilized at all time on all work on sites, and our goal is to get our team, and yours, home safely.
