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

292 individual interior and exterior LiDAR scans were completed in a single day, capturing existing conditions including all historical features, all without disrupting the historic site's operations or impacting its valuable contents so that a renovation could be designed and planned without requiring time consuming hand-measurements.

3D laser scanning a historic Massachusetts library to create a 3D BIM model.

GPRS 3D laser scanned a historic library in Amherst, Massachusetts and created an LOD 300 Revit model for the architect. The interior and exterior of the library was 3D scanned, this was an estimated 47,000 sq. ft. of space with 4 levels.

Built in 1919: there were no existing as-built details availableIt was likely that the existing condition of the building included unsquared architectural features The library’s historic features had to be preserved and intact during and post-renovation The library needed to remain open to patrons and conduct regular operations while visualization was completedPaintings of Emily Dickinson and Robert Frost, plus local historical exhibits, were contained in a gallery on site that needed to remain untouched Laser scanning was executed on Patriot’s Day, a Massachusetts state holiday. The library was closed so all scans could be completed without disrupting operations292 laser scans were completed of the interior and exterior of the library; approximately 47,000 sq. ft. of space spanning four levels An intensity map point cloud and 3D BIM model were delivered to the client, giving them accurate data of the current as-built conditions 3D scanning provided updated floor plans and captured existing conditions via a 3D BIM model to speed redesign and planningArchitects, designers, and contractors could access and utilize the BIM model and 3D laser scanning data at any stage of the restoration process for reference3D laser scanning is non-contact; scanning from a distance minimized the risk of damaging historical art work and exhibits and was completed in a single day on site

3D Laser Scanning

The Kennedy Space Center used GPRS 3D laser scanning services during recent upgrades to Launch Complex 39B. Our client was installing piping from the mechanical room under the launch pad up to the surface where they terminate, rerouting overhead piping through the mechanical room, as well as, removing and installing new equipment. GPRS delivered accurate and reliable as-built data for the Kennedy Space Center to plan upgrades and reroute piping.

The Kennedy Space Center – Cape Canaveral, Florida 3D BIM Model to Upgrade Launch Complex 39B ‍ TASK: The Kennedy Space Center used GPRS 3D laser scanning services during recent upgrades to Launch Complex 39B. Our client was installing piping from the mechanical room under the launch pad up to the surface where they terminate, rerouting overhead piping through the mechanical room, as well as, removing and installing new equipment. GPRS delivered accurate and reliable as built data for the Kennedy Space Center to plan upgrades and reroute piping. ‍ CHALLENGE: The client needed fast and accurate as built documentation of the project areas so they could effectively plan upgrades and piping routes and note any clash points. Understanding exactly where the mechanical room equipment was located below the launch pad surface was crucial to this project and difficult to determine using a method other than 3D laser scanning. ‍ SOLUTION: The GPRS Mapping & Modeling Team delivered an LOD 300 3D BIM model of the structural and MEP details. Accurate information helped the client plan for the equipment and piping and determine the vertical penetration points. This saved time and money by prefabricating the piping offsite and minimizing rework from misaligned pipes and equipment.
