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 BIM model to develop architectural designs for restoration.

3D laser scan and model The House of the Seven Gables property in Salem, Massachusetts for 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.

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 Famous Group was able to create a mixed reality experience that included an enormous virtual panther skulking through the stadium and onto the Jumbotron, delighting the 70,000 fans in attendance, thanks to the accurate scans, models, and meshes provided by GPRS

GPRS 3D laser scanned The Bank of America Stadium and the Gentle Giant panther statue for The Famous Group and the Carolina Panthers to create a mixed-reality experience for the home opening football game vs. the New York Jets

GPRS 3D laser scanned The Bank of America Stadium and the Gentle Giant panther statue for The Famous Group and the Carolina Panthers to create a mixed-reality experience for the home opening football game vs. the New York Jets. GPRS delivered a 3D mesh model to assist in the creation of this mixed-reality experience.

Problem • To sell the realism of mixed reality, computer-generated objects must precisely interact with the physical environment • As-built information and a 3D model of The Bank of America Stadium did not exist Solution • In 1 ½ days on site, using a Leica P40 ScanStation, point cloud data of the interior field, stadium bowl, seating, and upper rigging area was captured • To give the panther virtual objects to climb on and interact with, CAD technicians used the point cloud data to create a Revit 2021 LOD 200 3D model of the stadium • The Gentle Giant panther statue at the front of the stadium was 3D laser scanned to create a triangulated 3D mesh model in .fbx file format for the animation/CGI Benefits • 3D laser scanning is a fast and accurate way to digitize real-world objects for use in computer-aided design (CAD) and mixed reality • 3D models are created in our corporate office by experienced engineers and CAD technicians • The Famous Group was able to create a mixed reality experience that included an enormous virtual panther skulking through the stadium and onto the Jumbotron, delighting the 70,000 fans in attendance

3D Laser Scanning

With 3D laser scan data, the client can accurately verify the existing HVAC and mechanical equipment within the building without having to worry about positioning or measurement error. This helps them to design their new systems more accurately and efficiently.‍

3D scanning services were performed for a 10-story office building, capturing existing above-ceiling interstitial HVAC systems on each floor, as well as mechanical rooms, chiller rooms, air handling unit rooms and a basement tunnel connecting the utility area to the office building. Over 240,000 square foot of space was laser scanned to document the as-is conditions. The client was upgrading the HVAC system and GPRS developed a 3D model to aid the design process and reduce clashes.

With the 3D laser scan data collected by GPRS, the client could accurately verify the existing HVAC and mechanical equipment within the building.

Location: Toledo, Ohio Task: 3D scanning services were performed for a 10-story office building, capturing existing above-ceiling interstitial HVAC systems on each floor, as well as mechanical rooms, chiller rooms, air handling unit rooms and a basement tunnel connecting the utility area to the office building. Over 240,000 square foot of space was laser scanned to document the as-is conditions. The client was upgrading the HVAC system and GPRS developed a 3D model to aid the design process and reduce clashes. Challenge: With the site being an active office building, it was critical that the required lidar scanning data was obtained with minimal interruptions. Accuracy was important and the space was vast, they needed complete documentation to plan for system upgrades, including above the acoustic tile that was to remain in place. Solutions: Using the RTC360 and P40 Leica 3D laser scanners, GPRS Project Managers 3D laser scanned the interstitial and mechanical space in the evenings to avoid interrupting the office workday. A laser scanner mounted to a tripod was extended above the ceiling tiles to capture the interstitial space. With the 3D laser scan data, the client can accurately verify the existing HVAC and mechanical equipment within the building without having to worry about positioning or measurement error. This enables them to design their new systems more accurately and efficiently. Deliverable: GPRS delivered point cloud data in .rcs file format usable in Autodesk products (Revit, AutoCAD, Navisworks, etc.) so the client can align and overlay the point cloud to their existing 3D Revit model to verify the location of large format ductwork located in the interstitial space. GPRS also provided a 3D model of the mechanical rooms, chiller rooms, air handling unit rooms and basement tunnel. An LOD 100 model of the structural space and an LOD 300 of the MEP space was delivered to the client. Added Value: GPRS customizes deliverables for each client, so they are only paying for what they need. Also, upon completion of the HVAC system upgrade and prior to ceiling tiles being installed, GPRS will re-mobilize to the site to capture the new as-built conditions of the space for future reference.
