Existing Conditions, a GPRS Company, provided 3D laser scanning and modeling services to support the completion of an award-winning expansion to Boston Logan International Airport.

• AECOM, Suffolk Construction, and Luis Vidal + Architects needed accurate existing conditions documentation of multiple existing spaces inside the airport • The contractor also needed precise as-built documentation of the new construction prior to sheetrock installation, to comply with Massport (Massachusetts Port Authority) regulations • Many of the spaces that needed to be scanned were congested with MEP runs and other infrastructure • All work had to be completed while the airport was in operation SOLUTION • Existing Conditions utilized multiple 3D laser scanners, including the small and nimble Leica BLK360 laser scanner, to capture the required data • The contractor was so impressed with our work on the initial project that they asked us back to scan additional spaces • 3D Revit models were created using the scan data to allow for remote planning BENEFITS • The accurate and comprehensive as-built data provided Boston Logan with a detailed record of the building’s current state before renovations were completed, and of the new construction • Highly detailed, accurate digital measurements assisted with the safe and successful expansion of the structure • The client and their subcontractors could reference this data as they completed their work, and it will be preserved for future O&M purposes

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

3D laser scanning can be used to verify the dimensional accuracy of structural steel components by comparing them to the dimensions specified in the engineering drawings.

Structural steel construction was underway on a $180 million, 127,000 sq. ft. shopping center designed to house 60 retailers. The client requested 3D laser scanning services to capture point cloud data from the structural steel and generate an LOD 200 AutoCAD model to verify the accuracy of existing 2D drawings. GPRS was tasked with 3D laser scanning the site and capturing all structural elements including exposed columns, beams and floor.

TruePoint was tasked with 3D laser scanning the site and capturing all structural elements including the exposed columns, beams and floor.

“We greatly appreciate TruePoint’s willingness to work in tandem with the other trades onsite and schedule their work around construction obstacles." -- R. Serra, Architect Location: Staten Island, NY Task: Structural steel construction was underway on a $180 million, 127,000 sq. ft. shopping center designed to house 60 retailers. The client requested 3D laser scanning services to capture point cloud data from the structural steel and generate an LOD 200 AutoCAD model to verify the accuracy of existing 2D drawings. TruePoint was tasked with 3d laser scanning the site and capturing all structural elements including exposed columns, beams and floor. Challenge: Verifying the accuracy of structural steel at this stage of construction is vital. Shop drawings sometimes do not reflect actual site conditions. With a project of this scope, possession of valid 2D drawings of the existing field conditions is imperative to keep the project on schedule. Solutions: 3D laser scanning measures large and complex steel structures quickly, precisely, and comprehensively. TruePoint 3D laser scanning professionals used survey-grade Leica laser scanners to capture the highest quality 3D data of the site. The TruePoint engineering team then converts the point cloud data into a 3D AutoCAD model and aligns it to the client’s 2D drawings. This allows structural engineers to verify the accuracy of the existing construction documentation. Deliverable: TruePoint’s team of in-house engineers delivered a 3D AutoCAD model of existing structural steel aligned to existing 2D AutoCAD drawings on the nearly 127,000 sq. ft. site. Analysis from 3D scan data is the best way to ensure precise measurements when dimensions are critical. Added Value: TruePoint quickly mobilized several in multiple phases in order to work around obstructions caused by ongoing construction and weather elements. TruePoint is a highly experienced team of 3D laser scanning professionals who deliver exceptional service, accurate data, and custom deliverables to expedite your project. TruePoint can quickly mobilize to your site and provide free quotes. 3D scanning provides a more accurate and complete model for structural engineers.
