3D Laser Scanning Services in Idaho

GPRS provided 3D laser scanning services for John Glenn International Airport in Columbus, Ohio. The client was upgrading the existing airport entrance. Renovations included the installation of a prefabricated ceiling panel system and new doors. The primary objective of the laser scan was to capture the ground, curbs, ceiling beams, and related structural features to design and prefabricate the upgrades.

John Glenn International Airport – Columbus, Ohio Airport Entrance Upgrades Requires 3D Laser Scanning ‍ TASK: GPRS provided 3D laser scanning services for John Glenn International Airport in Columbus, Ohio. The client was upgrading the existing airport entrance. Renovations included the installation of a prefabricated ceiling panel system and new doors. The primary objective of the laser scan was to capture the ground, curbs, ceiling beams, and related structural features to design and prefabricate the upgrades. ‍ CHALLENGE: The client had a 60-day window to complete renovations, and no in-house engineers. The airport entrance did not match the architectural drawing; the ceiling structure was sloped where the drawings showed it level, and differing beam heights and widths between two levels of the airport created additional challenges. They needed accurate as builts to tie the upgrades to the existing structure and align with the camber of the structure. The client also had to deliver precise measurements to the ceiling panel system prefabricator and to provide the builders of the custom doors precise measurements on entryways. This would minimize any assumptions that could lead to field changes and schedule delays during construction. ‍ SOLUTION: The airport, which serves 7 million annual travelers, needed to remain in operation with little to no interruption of services. So, 3D laser scanning was completed at night during low passenger activity periods, so the airport could remain in operation. The GPRS Mapping & Modeling Team worked closely with the client to create maps and models to expedite components and minimize inaccuracies. 2D CAD drawings, and a 3D BIM model were delivered, which eliminated field adjustments and delays during renovations. The laser scan data also helped the client to plan how the new entrance would tie into the existing entrance, while taking into account all of the field variables.

3D Laser Scanning

GPRS saved the GC untold labor hours and cost overruns by detecting clashes, finding deviations before they caused expensive rework, and discovering the buried slab.

Complete subsurface mapping and millimeter-accurate aboveground measurements for a top-down, 360° visualization of a hospital wing and parking area to support a hospital expansion.

The addition is designed to occupy an existing parking lot for hospital employees, patients, and visitors. GPRS performed utility locating, video pipe inspection, and 3D laser scanning to create a comprehensive map and 3D model of the medical center’s infrastructure, both above and below ground.

TASK: Complete subsurface mapping and millimeter-accurate aboveground measurements for a top-down, 360° visualization of a hospital wing and parking area to support a hospital expansion. PROJECT APPLICATION: Rudolph Libbe, a longtime GPRS client and partner, oversaw the construction on the expansion of a northwest Ohio medical center. The addition is designed to occupy an existing parking lot for hospital employees, patients, and visitors. GPRS performed utility locating, video pipe inspection, and 3D laser scanning to create a comprehensive map and 3D model of the medical center’s infrastructure, both above and below ground. PROBLEM SOLUTION BENEFITS n Rudolph Libbe received millimeteraccurate laser scan data and an integrated 3D BIM model to precisely design and plan the building addition during preconstruction. n Non-destructive utility-locate methods reduced the number of unknown utilities and obstructions for the design and construction teams. n GPRS’ as builts allowed Rudolph Libbe to plan the new foundation and identify areas where further investigation would be warranted to prevent design and utility clashes. n With comprehensive field services provided by GPRS, Rudolph Libbe saved time and money on change orders, and eliminated subsurface damage during the construction process. With parts of the medical center’s campus dating back to the mid- 1800s, inaccurate as built data and unknown subsurface obstructions could jeopardize construction planning. n It was imperative that the proposed locations of the structural foundation and planned utilities coordinated with the existing conditions. n Rudolph Libbe desired 3D as builts to plan and complete the building addition, such as structural and utility tie-in information. n Traditional exploration methods typically include “soft” excavation methods over the entire building footprint. This option is expensive, time consuming, and requires tremendous coordination. GPRS utilized ground penetrating radar (GPR) and electromagnetic (EM) locating to map the hospital’s utilities. n Video pipe inspection (VPI) recorded the precise location and condition of the facility’s sewer lines, detailed in a NASSCO-certified report. n 3D laser scanning documented as built site data and utility maps to create 2D CAD drawings and a 3D BIM model for virtual design and construction. n GPRS participated in coordination meetings with construction and design team members. NO ONE HAS GONE TO THIS EXTENT TO MAP A SITE ABOVE AND BELOW GROUND. IT WAS IMPERATIVE THAT RUDOLPH LIBBE HAD ACCURATE AS BUILT SITE DATA AND UTILITY MAPS WITH CRITICAL STRUCTURAL AND UTILITY TIE-IN INFORMATION.” JAIME ALTHAUSER | FIELD SUPPORT DIRECTOR, GPRS

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.
