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 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.

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.

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.

GPRS Located, marked, and mapped all utility and sewer lines at Manufacturing Facility, and provide comprehensive infrastructure data management for O&M purposes. The manufacturing facility needed a permanent record of their 60-acre facility’s buried infrastructureData needed to be secure, yet easily accessible for facility manager and their teamPerdue previously spent $100,000 on a full site scan, but the contractor left them with only the field markings and hand-drawn utility maps The manufacturing facility was familiar with GPRS’ capabilities, having previously hired us for utility locatesExisting relationship between the two companies led to the manufacturing facility hiring GPRS to locate and map the entire facility’s buried infrastructure, and conduct drone flyovers of the siteThis accurate, field-verified data was uploaded into SiteMap® Pro, where the manufacturing facility has 24/7, secure access The facility had secure, 24/7 access to accurate, field-verified infrastructure data that they can use for future O&MGPRS and the facility entered into a SiteMap® Pro agreement, where Perdue will pay a subscription fee to continue to have access to their infrastructure data
