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.

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.

A Michigan 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.

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.

3D Laser Scanning

To complete the restoration of the church, the client required accurate 2D CAD drawings with precise measurements of the structural and architectural elements.

Our client needed accurate as built documentation to complete a $1.2 million restoration and improvement project for a historic church. The 1875-built church in Glandorf, Ohio was the largest Roman Catholic church built at the time. Built in Neo-Gothic style, it contained a 225-foot spire, beautiful statues imported from Austria and stained-glass windows imported from Germany. In 2017, the church underwent a 3-month historic restoration and improvement project. The project involved preventive measures including fiber-glassing the interior walls, painting and installing updated storm windows to protect the stained glass. In addition, damaged sections of the archway and niches were repaired, and a ceiling was lowered in the vestibule to highlight a stained-glass window.

GPRS’ client needed accurate as-built documentation to complete a $1.2 million restoration and improvement project for a historic church.

Our client provides historic restoration services and is dedicated to providing excellence in conservation and restoration. To complete the restoration of the church, the client required accurate CAD drawings with precise measurements of the structural and architectural elements. With a Leica P40 laser scanner, GPRS quickly captured the structural and architectural details of the church’s interior with92 laser scans. 3D laser scanning captured full spatial and color data with high detail and precision. Laser scanning can capture extreme detail for even the most intricate buildings easily. 3D laser scanning delivered a valuable data set to the client. Intensity map point cloud files provided digital visualization. 2D CAD drawings were created from accurate scan data. From skyscrapers to sewer lines, GPRS Intelligently Visualizes The Built World® to keep your projects on time, on budget, and safe.

3D Laser Scanning

In less than two hours on site, GPRS 3D Laser Scanning captured all aboveground features and utility field markings that were then used to provide integrated above and below-ground plan view of the campus via 2D CAD drawings to plan HVAC upgrades, and have accurate existing condition documentation for future use

A Los Angeles, California high school required 3D laser scanning of the above ground and below ground infrastructure to create 2D CAD drawings and plan for HVAC system upgrades throughout the campus

In less than two hours on site, GPRS 3D Laser Scanning captured all aboveground features and utility field markings that were then used to provide a integrated above and below-ground plan view of the campus via 2D CAD drawings to plan HVAC upgrades, and have accurate existing condition documentation for future use.

Problem • A 12-year-old high school was replacing the piping on 16 HVAC units throughout the campus. • The piping for these units runs intricately in and out of buildings, and through retaining walls and mechanical yards. • The areas that the pipes thread through do not have any as-builts or existing plans. Solution • Using the Leica RTC360 laser scanner, a Project Manager captured elements of the surrounding campus and GPR markings in less than hours on site • This project was laser scanned in full color, allowing the client to easily visualize and identify structural elements, pipes, conduits, and concrete reinforcement points inside the point cloud • CAD engineers created 2D AutoCAD floor plans and exterior elevations, PDFs with and without the point cloud overlayed Benefits • The combination of laser scanning structural and ground penetrating radar markings provided the client a high definition 3D comprehensive view of the campus, including both visible and invisible elements • With 3D laser scan data, the client can verify the HVAC mechanical equipment with confidence knowing high accuracy instruments minimize position error throughout the 3D space • The client has the most up-to date, accurate and comprehensive information to design HVAC upgrades
