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

When plant engineers at a pet food packaging facility needed to make modifications, they asked GPRS 3D Laser Scanning to provide as built documentation and a 3D model to plan retrofits to the existing structure. The project site consisted of 140,000 sq. ft. of interior space. Approximately 100,000 sq. ft. of this was single-story warehouse space, consisting of a central palletizer, semi- truck loading bays and temporary material storage. The remaining 40,000 sq. ft. contained 7 levels of elevated platforms containing product packaging equipment. TruePoint captured all architectural and structural features, equipment, conduit and piping.

Transforming a pet food facility with GPRS 3D Laser Scanning. Detailed documentation & 3D models streamline retrofit planning. Covering 140k sq.ft., including warehouses & elevated platforms.

CASE STUDY LOCATION Bowling Green, Kentucky TASK: When plant engineers at a pet food packaging facility needed to make modifications, they asked TruePoint Laser Scanning to provide as built documentation and a 3D model to plan retrofits to the existing structure. The project site consisted of 140,000 sq. ft. of interior space. Approximately 100,000 sq. ft. of this was single-story warehouse space, consisting of a central palletizer, semi- truck loading bays and temporary material storage. The remaining 40,000 sq. ft. contained 7 levels of elevated platforms containing product packaging equipment. TruePoint captured all architectural and structural features, equipment, conduit and piping. PROBLEM SOLUTION BENEFITS n By using laser scanning instead of traditional survey methods, TruePoint saved this client thousands of dollars in field survey work and drafting time, and provided greater detail than what would have otherwise been possible. With an accurate, comprehensive data set, plant engineers were able to complete virtual interference checks, avoiding design rework costs. n In two days on site, TruePoint’s experienced project managers 3D scanned the 140,000 sq. ft. area with millimeter accuracy. 523 scans were taken with the Leica P50 and RTC 360 laser scanners. This project was scanned on the weekend to avoid disruption to production. n After proper data registration, TruePoint’s in-house modeling team built an information-rich 3D BIM model for the client. TruePoint’s experienced team has optimized workflows for importing data, registration, creating deliverables, quality checks and transferring data to clients. n No as built plans existed for the facility. The plant was complex, capturing the existing spatial data of the conduit and piping in a high level of detail was important to the plant engineers. n There were silos and other pieces of large equipment that would be difficult to measure precisely using traditional or manual measuring techniques. /// GPRS LASER SCANNING SERVICES ///// 3D LASER SCANNING CASE STUDY: USING 3D LASER SCANNING FOR FACILITY DESIGN MODIFICATIONS “IT’S HARD FOR ME TO IMAGINE HOW THIS PET FOOD PACKAGING FACILITY COULD HAVE BEEN DOCUMENTED WITHOUT 3D LASER SCANNING.” TRUEPOINT PROJECT MANAGER

The cost avoidance impact of the integrated scan-to-BIM workflow saved the project an estimated 5% of the total contract amount, a savings of approximately $1,500,000.

GPRS provided 3D laser scanning and modeling services for a 15-story structure in the greater Cincinnati, Ohio area. This included 8 floors of commercial space, 2 stories of retail, 5 levels of parking garage, as well as the exterior façade and roof surface. The GPRS Project Manager captured over 1.54 million square-feet of space, and in-house engineers created a custom Revit model based on the point cloud of the existing conditions. Once construction was complete, this project received the 2017 Build Ohio Award for New Construction Over $30 million.
