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

Highlights THE BOTTOM LINE Reality capture provides the precise spatial data needed to power wayfinding apps and enable real-time AR navigation to help users confidently navigate complex indoor and outdoor environments. INDUSTRY Healthcare SERVICE Reality Capture LOCATION Altanta, Georgia PM Insight Reality capture plays a significant role in enhancing wayfinding, particularly in complex indoor or large outdoor environments. It allows for the creation of accurate digital representations of real-world spaces that can then be used to develop intuitive and efficient navigation systems. Deliverables 3D BIM Model, 2D CAD Drawings, Virtual Tour PROJECT APPLICATION Reality Capture for Wayfinding Task GPRS captured accurate digital representations for six uniquely structured parking garages at Emory St. Joseph’s Hospital in Atlanta and integrated data into a wayfinding app to improve patient and visitor navigation across the healthcare campus. PROBLEM The hospital campus featured multiple parking structures with inconsistent layouts, some aboveground, some underground, and some interconnected across levels. Patients and visitors frequently experienced difficulty navigating from their vehicles to their medical offices, resulting in frustration, delays, and operational strain on staff. The total space 3D scanned was 1,681,500 SF and included the following parking garages within the scope of work. Green Parking Garage - 6 Levels - 510,000 SF Blue Parking Garage - 2 Levels - 160,500 SF Purple Parking Garage - 5 Levels - 222,500 SF Gold Parking Garage - 3 Levels - 271,000 SF North Employee Garage - 6 Levels - 285,000 SF South Employee Garage - 5 levels - 232,500 SF ‍ Solution Before beginning reality capture, the team conducted walkthroughs of each parking deck with the client to confirm the scope and develop scanning strategies tailored to the vast and complex layouts, ensuring no disruption to hospital operations. In under a week, a three-person GPRS team used the Matterport Pro 3 and Leica RTC360 laser scanners to capture every parking level, space, stairway, and hospital access point. Accurate reality capture data was used to create individual 3D BIM models for each parking garage and a unified campus model, which served as the foundation for generating 2D plans and immersive virtual tours. Deliverables were integrated into a mobile wayfinding app with AR capabilities and indoor positioning to guide users through the hospital campus with ease. ‍ Benefits Reality capture provides the precise spatial data needed to power wayfinding apps, saving parking locations and enabling real-time AR navigation that helps users confidently navigate complex indoor and outdoor environments. The 3D BIM model forms the foundation for accurate routing, orientation, and destination mapping. Reality capture supports augmented reality (AR) overlays by aligning digital cues, like directional arrows or points of interest, with physical features in real-world spaces. Accurate wayfinding reduced reliance on staff for directions, improving hospital operational efficiency. As-built CAD and BIM documentation captured spatial data of the complex parking structures and can be used to support future planning and maintenance.

GPRS’ detailed 2D CAD drawings and 3D BIM model allow for safe cutting, coring & drilling for building-wide MEP and HVAC installations.

GPRS located and marked the full post-tension cable system layout for 12 floors of a 49-floor building, with approximately 12,500 sq. ft. of concrete on each floor. After concrete scanning was completed with ground penetrating radar technology, GPRS 3D laser scanned each floor to produce 2D CAD drawings and a 3D BIM model for virtual design and construction. The architect received a permanent record of the post-tension cable layout to complete fit and finish design plans for the building.

Mapping the PT cable layout in concrete slabs facilitates design and minimizes the risk of injuries and delays.

GPRS’ detailed 2D CAD drawings and 3D BIM model allow for safe cutting, coring & drilling for building-wide MEP and HVAC installations. Construction Concrete Scanning, 3D Laser Scanning & 3D BIM Modeling Concrete scanning services will locate critical targets like post tension cables, rebar, conduits, voids, and more to help keep your project on time, on budget, and safe. 3D laser scanning captures concrete markings with 2-4mm accuracy for GPRS to transform into custom 2D CAD drawings and 3D BIM models. GPRS located and marked the full post-tension cable system layout for 12 floors of a 49-floor building, with approximately 12,500 sq. ft. of concrete on each floor. After concrete scanning was completed with ground penetrating radar technology, GPRS 3D laser scanned each floor to produce 2D CAD drawings and a 3D BIM model for virtual design and construction. The architect received a permanent record of the post-tension cable layout to complete fit and finish design plans for the building. Post-tension cable location, spacing, and depth are determined by an engineer, are specific to each project, and must be traced in short distances to reveal the slope. Each tendon pulls 24,000 to 33,000 lbs. of pressure. Damaging a cable when cutting, coring, or drilling into a slab can cause a tendon to burst with enough force to cause severe injury or death, and impact the structural integrity of the slab. Replacing a single post-tension cable costs $10,000 - $20,000. Experienced Project Managers used ground penetrating radar (GPR) technology to locate and mark the precise details of each concrete reinforcement, documenting the location, number of cables, and depth directly on the slab and ceiling. After the post-tension layout was complete, each floor was 3D laser scanned to capture the field markings. That data was used to create a virtual tour, 2D CAD drawings (PT site layout and floor contours,) and a complete 3D BIM model of the site. The captured point cloud data was aligned to survey control, then to the client’s design model, further ensuring the accuracy of the data. GPRS has a verified 99.8% accuracy rate for concrete scanning, backed by our Green Box Guarantee. Laser scanning is accurate within 2-4mm. An accurate layout of post-tension cables protects tendons from damage, prevents injury and mistakes, and protects the integrity of the building. 2D plan sheets and a 2D floor contour map documenting the actual floor elevation added even more accuracy to the depth of cover that is field marked. The 3D BIM model provided the architect data to plan fit and finish designs and coordinate with contractors and MEP trades before build-out.
