3D Laser Scanning Services in North Carolina

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.

GPRS provided critical dimensional verification to ensure a flawless installation, reduce delays, clashes, and other unforeseen challenges for the project team

GPRS partnered with two renewable energy companies constructing an offshore wind farm to verify that the prefabricated components of several wind turbines met the specified design requirements

GPRS aids renewable energy projects with precise as-built data for design, construction, and maintenance. From solar panel installation to wind farm construction, we deliver accurate data for your project needs. 3D laser scanning captured complete and accurate dimensional information to verify that the prefabricated components were in tolerance for the design drawings Precast concrete foundations were laser scanned and a CAD comparison was performed to confirm that the dimensions matched the design planSubstation topside steel platforms were laser scanned to provide accurate as-built dimensions of all three levels and report the maximum outside diameter of the structure The Mapping & Modeling Team delivered 2D CAD drawings and a 3D BIM model, detailing the as-built dimensions and deviation between the design model and actual component 3D laser scanning captured complete and accurate dimensional information to verify that the prefabricated components were in tolerance for the design drawingsPrecast concrete foundations were laser scanned and a CAD comparison was performed to confirm that the dimensions matched the design planSubstation topside steel platforms were laser scanned to provide accurate as-built dimensions of all three levels and report the maximum outside diameter of the structureThe Mapping & Modeling Team delivered 2D CAD drawings and a 3D BIM model, detailing the as-built dimensions and deviation between the design model and actual component

The construction of a wind turbine required shipping prefabricated components on a vessel out to sea and using a crane to assemble Verification of the prefabricated component measurements within tolerance of the design drawings ensured a flawless installation Unique construction conditions meant there was no time to troubleshoot installation problems or add additional site visits and time at sea

GPRS’ accurate measurements allowed the client to order dimensionally-correct windows for each specific opening, thus reducing any change orders for this project. The client can review the 6-story building and its openings in 3 separate deliverables: the point cloud, the 2D drawings, and the TruViews.

To capture the dimensions of all the window openings on the building.

GPRS captured the accurate dimensions of the window openings safely from the ground.

Location: Detroit, Michigan Task: To capture the dimensions of all the window openings on the building. Challenge: The building was a 6-story building with windows on all four sides. The height alone of a 6-story building can create enough challenges when obtaining accurate measurements of window dimensions. This project, however, presented additional challenges. For example, the exterior of the building was not easily accessible by lift or scaffolding due to its being located along a busy road with minimal right of way. Additionally, the other sides of the building also had obstacles which further limited access to the windows. Solutions: By utilizing laser scanning, a non-contact measurement tool, GPRS was able to capture the accurate dimensions of the window openings safely from the ground, as well as from other safe locations. Windowsills can sometimes be difficult to capture when scanning from the ground, but our scan technicians were able to set up on and scan from surrounding buildings and rooftops to ensure enough elevation to capture these features accurately for our client. And since laser scanning is not only safe and accurate, but also is extremely fast, the field work was limited to one day. Deliverable: GPRS provided our client with 2D elevations in AutoCAD, which included the dimensions of the edge of existing rough openings dictated by the limestone cladding. Additionally, we supplied our client with TruViews – 3D photographs overlaid on top of the point cloud, allowing for rudimentary measurements directly from the photos. The client can now view the building and its openings in 3 separate deliverables: the point cloud, the 2D drawings, and the TruViews. Added Value: Many times, in field measuring, there is an assumption made, after measuring several similar units, that others will likely be of the same dimensions. With laser scanning we can easily and accurately determine the dimensions of each opening individually. As is common with many older buildings, many of the openings of this building appeared to be the same size but, in fact, varied enough to cause potential problems. GPRS’ accurate measurements allowed the client to order dimensionally-correct windows for each specific opening, thus reducing any change orders for windows that did not fit perfectly the first time they were placed.
