John Glenn International Airport – Columbus, Ohio Airport Entrance Upgrades Requires 3D Laser Scanning ‍ TASK: GPRS provided 3D laser scanning services for John Glenn International Airport in Columbus, Ohio. The client was upgrading the existing airport entrance. Renovations included the installation of a prefabricated ceiling panel system and new doors. The primary objective of the laser scan was to capture the ground, curbs, ceiling beams, and related structural features to design and prefabricate the upgrades. ‍ CHALLENGE: The client had a 60-day window to complete renovations, and no in-house engineers. The airport entrance did not match the architectural drawing; the ceiling structure was sloped where the drawings showed it level, and differing beam heights and widths between two levels of the airport created additional challenges. They needed accurate as builts to tie the upgrades to the existing structure and align with the camber of the structure. The client also had to deliver precise measurements to the ceiling panel system prefabricator and to provide the builders of the custom doors precise measurements on entryways. This would minimize any assumptions that could lead to field changes and schedule delays during construction. ‍ SOLUTION: The airport, which serves 7 million annual travelers, needed to remain in operation with little to no interruption of services. So, 3D laser scanning was completed at night during low passenger activity periods, so the airport could remain in operation. The GPRS Mapping & Modeling Team worked closely with the client to create maps and models to expedite components and minimize inaccuracies. 2D CAD drawings, and a 3D BIM model were delivered, which eliminated field adjustments and delays during renovations. The laser scan data also helped the client to plan how the new entrance would tie into the existing entrance, while taking into account all of the field variables.

3D Laser Scanning

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.

Quote from GPRS Team Member: “The scanning and modeling teams worked around the clock, sometimes 7 days a week, to complete this project. The hard work paid off and we’re thrilled with the result – one of our most highly-detailed architectural 3D models to date.” - Nate Baker, GPRS Service Line Leader – 3D Laser Scanning Location: Philadelphia, Pennsylvania Task: GPRS Laser Scanning developed an as-built model to aid this client in converting a historic building into a luxury hotel. GPRS provided 3D scanning services for a 250,000 square-foot building, including the exterior facades, floors 1-4, basement, roof, penthouses and mechanical spaces. GPRS’ team of in-house architects, engineers and CAD Technicians delivered point cloud files, a 3D model, and TruViews to the client. Challenge: The client was challenged with acquiring highly detailed architectural data including walls, ceilings, floors, stairs, balustrades, colonnades etc., and structural data including exposed columns and beams to design the renovation. Due to the size of the building and the ornate features, traditional methods would have taken months to complete and would not have been as accurate or anywhere near as detailed. Solutions: The GPRS scan technician completed 1,680 laser scans in 15 days (an average of over 100 scans per day!) with a Leica P20 ScanStation. A 3D Revit model with varying degrees of LOD 200 and LOD 300 modeling was generated by GPRS’ engineers based on the client’s instruction. Some areas of the building, such as the main lobby and exterior facades, required finer modeling detail over 350. This was deciphered through several project scope conferences between GPRS and the client. Deliverables: GPRS delivered point cloud files (.rcs file formats), a 3D Revit model and TruViews to the client. GPRS worked closely with the project architect to review the model in real time utilizing BIM360 software for shared viewing of the model in its current state throughout the 2-month project. Added Value: 3D laser scanning aids the process of architectural design from the early stages of site documentation and conceptualization, to monitoring construction progress and verifying as-built accuracy. Aside from the benefits of quickly and accurately creating detailed as-built drawings of a site, the data acquired through laser scanning has continued value throughout the project's life. Laser scanning and modeling is exploding in the AEC industry. 3D laser scanning creates a smooth BIM workflow, from the acquisition of data to a polished 3D model. Scan to BIM services are becoming more popular as the need for intelligent 3D CAD models grows.
