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.

ClearEdge3D Edgewise software was used to process piping and quickly create a 3D MEP BIM model for the client.

GPRS 3D laser scanned 40,000 square feet of office space on the 6th floor of a building in Cincinnati, Ohio. The area was recently renovated, and the objective was to capture MEP features to create an accurate as-built survey for the client. GPRS’ Project Manager used a Leica P40 ScanStation to capture 3D point cloud data for the GPRS’ Mapping and Modeling team to create a 3D BIM model.

Location: Cincinnati, OH Task: GPRS 3D laser scanned 40,000 square feet of office space on the 6th floor of a building in Cincinnati. The area was recently renovated, and the objective was to capture MEP features to create an accurate as-built survey for the client. GPRS’ Project Manager used a Leica P40 ScanStation to capture 3D point cloud data and GPRS’ in-house engineers created a 3D CAD model. Challenge: The client wanted to complete the laser scan after the space had been framed in, but before the ceiling grid and tiles were installed. This gave the client a very limited window of time to capture the above ceiling piping. They wanted to quickly and accurately capture all MEP components and pipes, so they could install the ceiling and begin to populate the space. Solutions: GPRS maintained constant communication with the client to schedule the scanning just before ceiling grid was installed. With just a few days’ notice, the Project Manager mobilized to the site. GPRS’ experienced technician could ensure that 3D laser scan technology would completely and accurately capture the as-built site conditions. Laser scanning was completed while other contractors continued their work, and complex areas were scheduled during the hours when contractors were off-site. Deliverables: GPRS provided the client with Autodesk Recap files and Black and White Leica TruViews. Also, using preliminary EdgeWise extraction, GPRS engineers provided an AutoCAD .dwg file to the client. Added Value: The scan technician worked during off-peak times, which expedited GPRS’ time on site. Additionally, GPRS’ engineers are trained and experienced in numerous software applications and can create custom deliverables for each client quickly. In this case, ClearEdge 3D Edgewise software was used to process piping and quickly create a 3D model.

A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations. Our client was an architecture, planning and interior design firm specializing in commercial, institutional and academic design.

Location: Denver, Colorado Task: A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations. Our client was an architecture, planning and interior design firm specializing in commercial, institutional and academic design. Problem: Construction documents existed from the original build, but the client was unsure if they were up to date. Each building required a different scanning scope. The church and parish hall required complete exterior and interior documentation, while the school required only exterior documentation. The church required new design drawings and cost estimates from the firm before proceeding with renovations. Solution: In one day on-site, a GPRS/TruePoint Project Manager completed 359 scans with the Leica P50 ScanStation and the RTC360 laser scanner. The client required point cloud files, 2D CAD drawings, a 3D Revit model, and TruViews to understand the existing conditions of the buildings on campus. 2D CAD exterior elevations and floor plans of the church; and exterior elevations of the school were created for this project. An LOD 200 Revit 2021 3D model of the church was delivered with architectural/structural details, including columns, beams, walls, floors, ceilings, doors, windows, stairs, roof, pews, lectern, and alter. An LOD 200 Revit model was delivered of the school exterior. Benefits: Renovations are not new to this campus; they recently added an outdoor learning lab and eucharistic adoration chapel. They understand the value of accurate as-built data. The firm wanted to keep the historic craftsmanship of the church but provide modern updates. A quality point cloud created a reliable as-built BIM model of existing conditions with ¼ inch accuracy tolerance.
