3D Laser Scanning Services in Rhode Island

The deliverables provided will be an asset for years to come as they can be referenced for any future coring or drilling needs showing where everything embedded in the slab was prior to pouring.

The client was in active build of an eight-story apartment complex in Houston, Texas. Each floor had five to six concrete pours scheduled on specific dates over an 8-month period. GPRS 3D laser scanned each area to capture the existing conduit, post-tensioning, rebar plan and sleeves prior to the slab being poured. This allowed the client to check the existing conditions for any irregularities.

Location: Houston, Texas Task: The client was in active build of an eight-story apartment complex in Houston, Texas. Each floor had five to six concrete pours scheduled on specific dates over an 8-month period. GPRS 3D laser scanned each area to capture the existing conduit, post-tensioning, rebar plan and sleeves prior to the slab being poured. This allowed the client to check the existing conditions for any irregularities. Challenge: The client was on a strict timeline and did not want delays in construction. They needed to quickly and accurate ensure that everything was in its correct location prior to pouring the slab. The client needed a 3D laser scanning company who could quickly mobilize to the site, conduct efficient laser scanning and provide point cloud data aligned to the design drawings within 24-48 hours. Solution: GPRS worked closely with the client. The scan technician mobilized to the site 1-2 times a week for 8 months and quickly captured the data without stalling the construction process. The scan technician set up the laser scanner at multiple locations around each slab and captured the data without disturbing the active construction site. GPRS’ team of in-house engineers quickly provided the point cloud alignment. The sub-centimeter point cloud data allowed the client to review the site conditions and make changes prior to the scheduled pour and without ever having to leave the office. Deliverable: GPRS’ Project Manager laser scanned each area and provided a colorized point cloud to the client. The colorized point cloud allowed the client to see color imagery, stitched over the point cloud to assess the area for misplaced sleeves, conduits and post-tension runs. This data was also aligned to the existing building plans to quickly find any issues. Added Value: The client relayed that GPRS saved them thousands of the dollars with just the first mobilization. They identified issues with the sleeve alignment from the home office and had them corrected prior to the slab being poured. Finding out that the sleeves were not in the correct location, even the day after the pour, would have cost the general contractor tens of thousands of dollars in coring costs alone. And if this problem would not have been discovered until framing and other elements went up could have cost exponentially more.

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.

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.
