3D Laser Scanning Services in Florida

Capturing basic structural and architectural features will immensely help the architect in planning the hotel renovations.

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.

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.

3D Laser Scanning

GPRS’ accurate measurements allowed the client to order dimensionally-correct windows for each specific opening, thus reducing any change orders for this project. The client can review the 6-story building and its openings in 3 separate deliverables: the point cloud, the 2D drawings, and the TruViews.

To capture the dimensions of all the window openings on the building.

GPRS captured the accurate dimensions of the window openings safely from the ground.

Location: Detroit, Michigan Task: To capture the dimensions of all the window openings on the building. Challenge: The building was a 6-story building with windows on all four sides. The height alone of a 6-story building can create enough challenges when obtaining accurate measurements of window dimensions. This project, however, presented additional challenges. For example, the exterior of the building was not easily accessible by lift or scaffolding due to its being located along a busy road with minimal right of way. Additionally, the other sides of the building also had obstacles which further limited access to the windows. Solutions: By utilizing laser scanning, a non-contact measurement tool, GPRS was able to capture the accurate dimensions of the window openings safely from the ground, as well as from other safe locations. Windowsills can sometimes be difficult to capture when scanning from the ground, but our scan technicians were able to set up on and scan from surrounding buildings and rooftops to ensure enough elevation to capture these features accurately for our client. And since laser scanning is not only safe and accurate, but also is extremely fast, the field work was limited to one day. Deliverable: GPRS provided our client with 2D elevations in AutoCAD, which included the dimensions of the edge of existing rough openings dictated by the limestone cladding. Additionally, we supplied our client with TruViews – 3D photographs overlaid on top of the point cloud, allowing for rudimentary measurements directly from the photos. The client can now view the building and its openings in 3 separate deliverables: the point cloud, the 2D drawings, and the TruViews. Added Value: Many times, in field measuring, there is an assumption made, after measuring several similar units, that others will likely be of the same dimensions. With laser scanning we can easily and accurately determine the dimensions of each opening individually. As is common with many older buildings, many of the openings of this building appeared to be the same size but, in fact, varied enough to cause potential problems. GPRS’ accurate measurements allowed the client to order dimensionally-correct windows for each specific opening, thus reducing any change orders for windows that did not fit perfectly the first time they were placed.

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
