THE BOTTOM LINE
The data GPRS collects can be used to develop the utility portion of a conceptual site model (CSM) to visualize migration routes, communicate with stakeholders, make informed remediation decisions, and protect the team on site and the environment.

PROJECT APPLICATION
ASK
A gas station requested utility locate and as-built data to document the existing conditions for site upgrades and to develop an emergency response plan for potential leaks. Accurate 2D utility locate maps, a 3D BIM model, and a conceptual site model (CSM) were created of the gas station, underground storage tank system, and surrounding utilities.
Task
A gas station requested utility locate and as built data to document the existing conditions for site upgrades and to develop an emergency response plan for potential leaks. Accurate 2D utility locate maps, a 3D BIM model, and a conceptual site model (CSM) were created of the gas station, underground storage tank system, and surrounding utilities.
PROBLEM
- The gas station lacked as built site information required for compliance with environmental regulations, essential to plan for site upgrades, and necessary to take prompt corrective action in the case of an emergency.
- The client did not have an accurate conceptual site model (CSM) to understand and interpret contaminant fate and transport in the subsurface.
Solution
- GPRS Project Managers used state-of-the art equipment to perform ground penetrating radar (GPR), electromagnetic (EM) locating, video pipe inspection (VPI), leak detection, 3D laser scanning, and drone photogrammetry services at the gas station.
- The GPRS Mapping & Modeling Team delivered accurate as built and utility location data in point cloud, 2D maps, 3D BIM model formats, to help eliminate guesswork from decision making, and prevent time-consuming and dangerous mistakes and the costs associated with them.
- The gas station received access to millimeter-accurate information to efficiently plan work and drill safely.
- Locating underground storage tanks, including their depths, can help the station owner detect unusual fluctuations in fuel levels and assess any potential leak faster.
- Detailed site maps can help to communicate the location of a leak, the most likely paths and extent of horizontal and vertical delineation, and to plan assessment and mitigation efforts.
Benefits
- Infrastructure location and mapping are vital before conducting any construction or subsurface work like soil boring, or coring concrete to drop vapor pins – to eliminate clashes and utility strikes and keep workers and the community safe.
- Comprehensive site data is essential for the early detection and management of petroleum leaks at a gas station, to help minimize environmental damage and ensure the safety of employees and the surrounding community.
- GPRS as built maps and models provide accurate information to avoid hitting a UST or system component, and to avoid a utility strike when sampling soil.
- The GPRS SiteMap® mobile app securely stores utility data, geolocated and layered, and securely accessible for the station stakeholders to share with those who may need it.
- The data GPRS collects can also be used to develop the utility portion of a conceptual site model (CSM) to visualize migration routes, communicate with stakeholders, make informed remediation decisions, and protect the team on site and the environment.
