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

A hotel developer plans to invest $30 million to renovate a 200-room hotel in downtown Toledo, Ohio. Case Study: 3D Laser Scanning Aids In Hotel Renovation Location: Toledo, Ohio TASK: A hotel developer plans to invest $30 million to renovate a 200-room hotel in downtown Toledo, Ohio. GPRS performed laser scanning services to aid this client in the renovation. GPRS 3D laser scanned the exterior elevation, basement, main lobby level, 2nd floor and elevator shaft – more than 30,000 square feet of space. All structural and architectural features were captured as part of the scan. PROBLEM: No accurate as-built drawings existed. It would have been difficult, costly and time consuming to manually measure the 19-story building. The developer was not local, making transportation and lodging an added expense. Safety was also a concern, as the building was partially demolished and contained asbestos. SOLUTION: GPRS quickly mobilized to the site and captured the existing conditions of the hotel. Using a P40 survey-grade Leica ScanStation, the local GPRS Project Manager tied the data to survey control, achieved 2-4mm accuracy, and mitigated movement, ensuring level scans. The client received .rcs Intensity Map Point Cloud files, 2D AutoCAD Floor Plans, 2D Point Cloud Sheets, a 3D Revit 2017 LOD 100 Model and TruViews. To save costs and expedite this project, only the unique floors of the hotel were laser scanned. Capturing the basic structural and architectural features will immensely help the architect in planning the hotel renovations. Laser scanning quickly captured precise data while avoiding the risk of the unsafe environment. GPRS collected all building information, eliminating the need to return to the site for additional measurements. For 3D laser scanning of hotels and other resort properties, contact GPRS.

Brick Manufacturer Uses 3D Laser Scanning For Facility Upgrades Location: Shoemakersville, Pennsylvania Task: The demand for wood molded brick continues to grow as architects and designers utilize more brick in building designs. To keep up with this demand, our client, the largest molded brick manufacturer in the United States, is planning upgrades to its Shoemakersville, Pennsylvania facility. These upgrades include adding a second kiln to increase capacity and modernizing equipment to improve product quality. The client requested point cloud data, 2D CAD drawings, and a 3D Revit model to understand the existing conditions of the facility. Challenge: Our client was on a tight timeline. They requested as-built data, 2D drawings and a 3D BIM model of their 150,000 square feet facility in 12 business days. To complete the facility upgrades, they needed line, equipment, and tie-in points. Solution: 150,000 sq. ft. of space was 3D laser scanned in two days on-site with the Leica P50 ScanStation and the RTC360 laser scanner. 279 laser scans were taken to capture complete as-built data of the site’s structure, equipment, and MEP. Deliverable: GPRS delivered an LOD 200 design-intent architectural, structural, and MEP Revit Model, 2D AutoCAD floor plans and interior elevations, and an RCS point cloud file. MEP piping and conduit 2 inch and larger, HVAC ductwork, pumps, motors and equipment were 3D modeled to within ¼ inch accuracy. The 3D model will allow our client to discover any discrepancies between the design and existing conditions so they can make necessary adjustments before the facility upgrade begins. Added Value: Coordinating the work of designers with structural, MEP, and other construction teams is often difficult. Laser scanning provides a fast and accurate way to collect large amounts of site measurement data which can be used to expedite the retrofit design process. 3D scanning will help this client design to the actual as-built conditions, reducing clashes and change orders. Inaccurate data would slow teams down, increase the risk of miscommunication, and create prefabrication and installation problems that could lead to rework.
