3D Laser Scanning Services in New York

Architects and mechanical contractors could plan both the demolition of the existing systems and the implementation of the new systems without jeopardizing the Frank Lloyd Wright Unity Temple's aesthetics and spatial design.

To laser scan both the interior and exterior of Frank Lloyd Wright’s Unity Temple and produce a 3D BIM model for historical renovation documentation.

GPRS laser scanned the interior and exterior of Frank Lloyd Wright’s Unity Temple to produce a 3D BIM model for historical renovation documentation.

Location: Unity Temple in Oak Park, Illinois Task: To laser scan both the interior and exterior of Frank Lloyd Wright’s Unity Temple and produce a 3D BIM model for historical renovation documentation. Challenge: The challenge in this case was to be able to thoroughly document the 1909 Frank Lloyd Wright masterpiece—in order to prepare for a multi-million dollar building restoration—without compromising the building’s historical identity or disrupting ongoing tourism and church activities within Unity Temple. Solutions: Building Information Modeling (BIM) has become a major practice within the AEC industry, specifically for new construction, adaptive reuse, or buildout projects. But how does this practice of “build twice” translate to restoring an early 19th century architectural marvel? By means of High Definition Surveying (HDS). HDS is a non-contact measuring tool that collects visible information of existing conditions in a fast, precise way while, at the same time, reducing damage risks and time associated with traditional measuring methods. Visible information is captured in 360 degrees, generating a 3D point cloud with accuracy up to 2 to 4mm. These point clouds ultimately become 3D virtual worlds of the building, making the method a fast and cost effective way to generate as-built documentation (both 2D and 3D) for project analysis and coordination. In the case of Unity Temple, TruePoint was hired for its expertise in historical preservation by means of laser scanning and BIM modeling. TruePoint’s team of architects and engineers performed a comprehensive laser scan of the building’s interior (temple, offices, mechanical basement, classrooms, etc.), exterior, roof, and skylights in order to capture explicit detail of Unity Temple’s current condition. TruePoint then created a 3D Revit model from the point cloud data so that the construction management firm and subcontractors (mechanical contractors, concrete restoration, architects, etc.) could investigate the building’s existing state and accurately assess their project designs for restoring Unity Temple. Deliverables: Deliverables included a 3D Revit model of the building’s interior, exterior, roof, and skylights; a colorized point cloud in Autodesk Recap file formats (.rcp/.rcs) to be used directly in Autodesk Software (Revit, AutoCAD, Navisworks, etc.); and TruView photographs. Added Value: The colorized point cloud generated from laser scanning gave explicit detailed information that would be otherwise nearly impossible or extremely difficult to document without risking damage to the fragile building elements. Examples of two key architectural features are the intricate window panes (e.g., clerestories, skylights) and the wood trim throughout Unity Temple. Both of these features were collected in the point cloud data in congruence with other building information (structure, mechanical systems, etc.). Additionally, TruePoint trained the client on how to create 2D elevations, sections, and a Reflected Ceiling Plan (RCP) directly from the point cloud data within AutoCAD. These AutoCAD sheets contained precise measurements and photographs, making it quick and easy for the client to identify the exact piece and location of each element for its removal, restoration, and re-implementation. TruePoint also provided the client with TruViews. The TruView utilizes a free plug-in for Internet Explorer in order to view each scan location from the scanner’s perspective. This offers a quick, easy way to take rudimentary measurements, make hyperlink notes, and perform project collaboration, thereby reducing the hassle, time, and cost associated with on-site visits. Another added bonus of producing a comprehensive point cloud and BIM model of Unity Temple was documenting the existing mechanical room and tunnel in relation to the entire structure. Mechanical contractors and architects could then plan both demolition of the existing systems and implementation of the new systems without jeopardizing Frank Lloyd Wright’s aesthetic and spatial design.

3D Laser Scanning

The level of detail provided to the client in both the 3D laser scan data and 3D BIM model exceeded expectations and helped the client to expedite fabrication drawings.

An electrical, mechanical, and fabrication construction services company requested 3D laser scanning and BIM modeling services to capture point cloud data and generate a 3D model of the inlet and outlet flange information for 27 natural gas separator units and 64 meter/regulation skids. A GPRS Project Manager captured detailed flange information, including bolt hole orientation, elevation information, and pitch of flanges with a 3D laser scanner. Then, using the point cloud data collected, the GPRS Mapping & Modeling Team generated a 3D model of each skid’s flange information. This information will be used by the client for prefabrication, with the goal of minimizing field changes during installation.

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.
