3D Laser Scanning Services in Maryland

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

GPRS provided 3D laser scanning and modeling services for a power plant in Ann Arbor, Michigan, which generates and processes four main services: steam, electricity, compressed air and domestic hot water. The objective was to as-built survey the 5-level building, basement, exterior facades, rooftop areas, electrical switch gear rooms, vaults and interstitial space below the control room. GPRS generated a 3D model in Bentley Microstation for the client’s use. The model included all civil, structural, electrical and mechanical features, including piping and conduits ½" in diameter and larger

GPRS provided 3D laser scanning and modeling services for a power plant in Ann Arbor, Michigan.

Location: Ann Arbor, Michigan Task: GPRS provided 3D laser scanning and modeling services for a power plant in Ann Arbor, Michigan, which generates and processes four main services: steam, electricity, compressed air and domestic hot water. The objective was to as-built survey the 5-level building, basement, exterior facades, rooftop areas, electrical switch gear rooms, vaults and interstitial space below the control room. GPRS generated a 3D model in Bentley Microstation for the client’s use. The model included all civil, structural, electrical and mechanical features, including piping and conduits ½" in diameter and larger. Challenge: The client needed to accurately document existing conditions. Due to the vast space and density of piping, it would have been much more difficult and time consuming to accurately depict the location of pipe runs, structural features and other details in the plant manually. It would have also been difficult and unsafe to capture overhead and structural features without the use of a lift. Solutions: Utilizing several scan technicians and multiple Leica laser scanners, including the Leica P-40, P-20, and C-10 ScanStation, GPRS was able to occupy existing plant benchmarks and orient the data to survey control. GPRS’ scan technicians captured full color panoramic photographs at each scan location with the on-board camera. GPRS completed over 1,200 individual scans for this project due to the density of the piping. Deliverables: GPRS’ team of in-house CAD technicians provided Microstation POD files, full-color TruViews and a Bentley Microstation V8i 3D model. Added Value: GPRS communicated directly with on-site personnel at the power plant and participated in daily work briefings to ensure compliance with plant safety protocol. Additionally, GPRS’ CAD technician visited the site with the scan technician, utilizing cutting edge methods to conduct in-field verification and quality assurance review of the 3D model on tablets in real time using both virtual reality and augmented reality methods.

3D Laser Scanning

With 3D laser scanning, the client avoided the costs of renting a lift, manually measuring the façade, and the potential of inaccurate and incomplete data.

This client needed to do some rehabilitation on a historic cathedral in Denver, Colorado. After experiencing 100 years of weather in Denver, the cathedral had damage to the exterior stonework. GPRS laser scanned the exterior front façade of the historic cathedral and provided the client with 2D drawings.

GPRS worked quickly to define the scope of work, document a proposal, provide 3D laser scanning services and deliver a 2D drawing for this project.

Case Study: Historic Cathedral Needs 3D Laser Scanning Of Front Façade Location: Denver, Colorado Task: This client needed to do some rehabilitation on a historic cathedral in Denver, Colorado. After experiencing 100 years of weather in Denver, the cathedral had damage to the exterior stonework. GPRS laser scanned the exterior front façade of the historic cathedral and provided the client with 2D drawings. Problem: Prior to beginning work, the client needed accurate drawings to document the locations of stonework that needed maintenance. The client was pressed for time and needed an immediate turnaround for 3D laser scanning services and a 2D drawing. They also had a minimal budget for this project. Solution: GPRS worked quickly to define the scope of work, document a proposal, provide 3D laser scanning services and deliver a 2D drawing for this project. The Project Manager was able to scan the exterior façade within a few hours. GPRS quickly captured the entire front facade from the ground without the need for a lift. The Leica C10 laser scanner was used, whose range exceeds 900 feet and possesses accuracy that is sub-centimeter, making 3D laser scanning a perfect option. GPRS supplied the client with 2D elevations of the plotted point cloud so they could document the exterior stone damage while on site. Benefits: The client avoided the costs of renting a lift, manually measuring the facade and the potential of inaccurate or incomplete data. GPRS offers an extensive team of laser scanning professionals, including Engineers and Architects, to provide a deliverable that is accurate, cost-efficient and timely.
