3D Laser Scanning Services in Washington D.C.

GPRS’ Mapping & Modeling Team communicated directly with the client to model exactly what was needed, keeping costs down by avoiding unnecessary modeling effort.

GPRS provided high-definition laser scanning services at a grain elevator in Michigan to capture the existing conditions of the site. The client needed an accurate representation of the structural features to perform maintenance upgrades. They wanted specific documentation of the bucket elevator legs, fill conveyor bridges, and tower supports.

Header: A GPRS Case Study: 3D Laser Scanning a Grain Elevator in Michigan Location: Near Saginaw, Michigan Task: GPRS provided high-definition laser scanning services at a grain elevator in Michigan to capture the as-is conditions of the site. The client needed an accurate representation of the structural features to perform maintenance upgrades. They wanted specific documentation of the bucket elevator legs, fill conveyor bridges and tower supports. Challenge: This was a complex site that included the grain elevator, silos, bins, tanks, conveyors and bridges. The area laser scanned was near 180,000 square feet with heights over 110 feet. Traditional means of measuring would be difficult, costly, time consuming and potentially hazardous. Solutions: The Project Manager completed laser scanning in two days utilizing the Leica C10 and Leica P40 laser scanners. Varying the position of the scanners on the ground and between silos, the technician was able to capture this complex site from a variety of angles. Additionally, the Project Manager occupied elevated positions and tied those scans to the scans performed at grade. All the scanning could be safely performed from a distance without climbing the structure and without the need for renting lifts or scaffolding. Deliverables: The client received Autodesk Recap files of the scans (.rcs file format), black and white TruViews of the site, a 3D AutoCAD Model of the site, and section and plan views of the model laid onto the point cloud data with callouts. Added Value: GPRS’ CAD technicians communicated directly with the client to focus on key areas for detailed modeling to model exactly what was needed to keep costs down by avoiding unnecessary modeling effort. Using advanced extraction techniques and specialized software, GPRS was able to accurately represent structural features and deliver these to the client.

In just one day on site, GPRS was able to capture the entire existing condition of the facility, even in dense pipe runs and hard-to-reach spaces, with 2-4mm accuracy to provide the client with an accurate 3D BIM model for planning, fabrication, and clash detection

An engineering firm needed to have existing conditions of a power plant documented and modeled to plan for renovations.

An engineering firm needed to have existing conditions of a power plant documented and modeled to plan for renovations.

Problem • The client needed to accurately document the existing conditions of the plant without interruptions to the power supply • Many of the pipe runs were dense and impossible to accurately measure by hand • The client required 2-4 mm accuracy of dense piping and pipe runs throughout the facility • The client needed to guarantee that installations complied with safety regulations Solution • In one day on site, GPRS' Project Manager used the Leica RTC360 laser scanner to capture 150 laser scans, documenting existing conditions of the facility • Many of the pipe runs were dense and impossible to accurately measure by hand • GPRS generated a 3D BIM model for use in CAD software, including all civil, structural, electrical, and mechanical features, piping, and conduit 1" and larger Benefits • Due to the vast space and density of the 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 • The point cloud data from laser scanning was used by CAD technicians to create an intelligent 3D BIM model for planning, fabrication and clash detection • Verified measurements and virtual planning guarantee installations will comply with safety regulations • Using virtual 3D models, the firm can plan and model future developments to manage the facility without having to re-enter the site

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
