Highlights THE BOTTOM LINE 3D laser scan data will help to identify structural issues, deterioration, and other factors affecting The House of the Seven Gables historical site and deliver the architect 2D plans and a 3D model to develop architectural designs for restoration. INDUSTRY Historical Preservation SERVICE 3D Laser Scanning; Mapping & Modeling LOCATION Salem, Massachusetts PM Insight The properties look well preserved from the outside, yet the historic site's preservation manager is aware of the the myriad ways climate change is threatening the integrity of the structures. Deliverables Point Cloud, 3D BIM Model, 2D CAD Elevations Task 3D laser scan and model The House of the Seven Gables property in Salem, Massachusetts for Union Studio Architects historical preservation. The exterior shells of the Turner-Ingersoll Mansion (also known as The House of the Seven Gables), The Retire Beckett House, Hooper-Hathaway House, Nathanial Hawthorne Birthplace, Primm House, and features of the Seaside Colonial Revival Gardens were 3D laser scanned with the Leica RTC360, capturing highly detailed and accurate digital as-builts, to deliver 2D elevations and a 3D BIM model of each property to the architect. PROBLEM The House of the Seven Gables strives to preserve their historic buildings in the face of several challenges, including deterioration due to climate, weakening of the seawall, and mold in the basement of the Nathaniel Hawthorne Birthplace. As a National Historic Landmark District, the property is confined by preservation standards set by the federal government and the town of Salem. Because of these terms, unlike making renovations to a modern home, every modification at the Seven Gables property must be approved by multiple stakeholders to ensure that historical accuracy is maintained. The client also had budget constraints due to the project’s nonprofit status, so the job scope narrowed from 3D laser scanning eight buildings to five. Existing Conditions, a GPRS company, worked closely with Union Studio to efficiently supply them with the data and deliverables they required, knowing the allocated budget for this project. Solution 3D laser scanning will play an important role in the preservation of these historic buildings, by delivering as-built data, drawings, and models for design planning and decision making. 3D laser scanning documented the exterior building shells, delivering precise measurements and building footprints. For the Hooper Hathaway House basement, 3D laser scanning captured the architectural and structural features, geometry, and spatial layout. Benefits 3D laser scanning captured highly detailed and accurate digital measurements of The Gables’ buildings and infrastructure to create as-built drawings and 3D BIM models for this architectural preservation project. Union Studio Architects can reference accurate site data to create and share design plans with all project stakeholders.

3D Laser Scanning

The client was able to fabricate components offsite and plan a flawless installation based on our existing condition data and 3D model. Plus, GPRS' work was conducted entirely at night, mitigating any disruption to construction

Field verification to prefabricate ACM panels

Our client was installing ACM panels to the canopy of a newly constructed airport terminal. The construction plans did not match the existing conditions at the site. A deviation could cause a major issue. The installation process needed to be precisely planned to avoid rework.

The construction plans did not match the existing conditions at the site. The installation process needed to be precisely planned to avoid rework • The shape of the canopy was complicated and stood 65 feet in the air. The client needed field verification and a plan to expedite proper installation of the panels • Installers were working overhead in a lift; there was no room for trial and error Solution • The Project Manager conducted a site walk to devise a plan for the client • The canopy and curtain wall of the airport terminal were 3D laser scanned to capture precise as-built data and generate a 3D model and 2D drawings to facilitate ACM panel installation • 22" x 34" 2D CAD drawings were created with the panel layout for the client to take to the field. This allowed each panel to be labeled with a custom number, cut and shim points Benefits • Laser scanning obtained exact measurements for the client and took away any guesswork from this project • To circumvent the active construction site, the Project Manager scanned the site at night to eliminate movement and trades working • The client was able to fabricate components offsite and plan a flawless installation

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.
