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

A Revit model will expedite design changes and fabrication of equipment to increase production capacity at the manufacturing plant.

3D laser scan a manufacturing facility that is receiving upgrades to three of its lines to capture point cloud data and generate a 3D Revit Model.

A specialty compound manufacturer was upgrading three manufacturing lines at its plant as part of a larger capital improvement plan.

A specialty compound manufacturer was upgrading three manufacturing lines at its plant as part of a larger capital improvement plan.The facility was originally built in the 1980's and has expanded several times over the years.Multiple levels in the facility needed scanned at a very high level of detail, capturing structural, architectural, MEP and civil elements, along with a site plan.The following areas required 3D laser scanning services:On the ground production level, GPRS captured extruder areas for lines 1-3 and process equipment.On the mezzanine level, GPRS captured mixers for each extrusion line.On the second floor, GPRS captured blender areas for lines 1-3, process equipment, air handling equipment, and additional rooms.Outside, GPRS captured the tank farm and silo farm. GPRS provides 3D laser scanning services for facility upgrades and expansions, delivering 2-4mm accurate dimensions of building infrastructure: structural, mechanical, electrical and plumbing features; furnaces, equipment, conduit and piping. With an accurate, comprehensive data set, plant engineers can install new equipment and upgrade the three manufacturing lines. The facility was 3D laser scanned on the weekend to minimize interruption to the manufacturing lines.73 scans were performed in one day with the Leica P40 ScanStation and the Leica RTC360 laser scanner, acquiring very high detail of the plant.Colorized point cloud, TruView Viewer files, and a Revit model were delivered to the client. 3D laser scanning and a Revit model will expedite design changes and fabrication of equipment to increase production capacity.The investment of laser scanning will reduce the project timeline, minimize downtime and change orders -- providing cost savings for the client.This client is pioneering innovation in its industry -- upgrading the lines with updated extruders will increase capacity for long-term growth while minimizing stoppages, set-up times, and scrap material.

THE BOTTOM LINE GPRS was tasked with 3D laser scanning the existing conditions of this $417 million Wastewater Treatment Plant and producing an LOD 350 Revit model to plan for future expansion. INDUSTRY Wastewater Treatment Plant SERVICE 3D Laser Scanning, Mapping & Modeling LOCATION Denver, Colorado PROJECT APPLICATION GPRS specializes in BIM and VDC management for wastewater treatment plants, utilizing 3D laser scanning technology to create detailed digital models. Task 59 acres and 27 buildings were 3D laser scanned to provide complete as-built documentation of a Colorado Wastewater Treatment Plant. This client is the largest water reclamation provider in the Rocky Mountain West, serving 1.8 million people in a 715 square-mile area. GPRS was tasked with 3D laser scanning the existing conditions of this $417 million facility and producing an LOD 350 Revit model to assist with on-going operations and plan for future expansion. PROBLEM The client needed the fastest way to document 59 acres and 27 buildings with the highest level of quality. Each building was unique and needed to be documented and modeled to plan for expansion, including pumping stations, sludge digester, thickener, tank reclamation, purification systems, aeration, primary and secondary settling, maintenance facilities and visitor center. The client had their own laser scanner, but did not have the manpower and resources to complete the project timely. Solution GPRS has a highly integrated and highly motivated team of laser scanning professionals. 59 acres of campus was 3D laser scanned in a 4-month period, sometimes with up to 10 Project Managers on site at one time. GPRS Project Managers captured 2,990 color scans and an in-house team of engineers produced an LOD 350 Revit model of the interior and exterior of 27 buildings of a 59 Acre Wastewater Treatment Plant including architectural and structural details, MEP and process piping ½" and above, valves, flanges, equipment detail and location, stairwells, railings, closets, restrooms and janitor rooms. The client also requested EdgeWise files, so the GPRS Mapping & Modeling Team modeled all piping, valves, flanges, ducts, conduit and framing and organized it in layers in accordance with the client’s naming conventions for location, plant process and material specifications. The client also used the BIM model to determine if the existing drawings reflected actual site conditions. Benefits 3D laser scanning enables clients to add, modify, validate and document their design digitally. 3D laser scanning allowed the plant to have a full scope of the existing conditions before renovations were made to the facility.
