Location: Social Circle, GA Project Manager Insight: “The cost of laser scanning and modeling should easily be offset by the cost savings from reduced re-work during the facility renovations.” Andy Foshee, TruePoint Southeast Regional Manager. Task: A pharmaceutical company was installing some new equipment in various areas of the facility. Existing machinery was being removed, new machinery was being installed and MEP piping was being re-routed throughout the area. TruePoint provided laser scanning services to collect point cloud data on four levels and generate a 3D model for the client. Before starting renovations of this existing facility, the client desired to document existing conditions and plan layout and process flow upgrades. Challenge: Upgrading existing pharmaceutical manufacturing sites can be challenging. The space available is restricted and bringing in new equipment is sometimes tricky. Our client needed to make several tie-ins and requested a Revit model for planning. Solution: Using the Leica P50 ScanStation, TruePoint captured structural features, MEP piping and equipment ½ inch and above. An LOD 300 Revit model was requested to ensure more accurate, efficient and cost-effective execution of the project. With planning, the client was able to install the new machinery and re-route piping without any field rework. This also resulted in reduced downtime and significant savings by returning the facility to production quickly. Deliverable: TruePoint delivered a point cloud .rcp file, JetStream Viewer file and an LOD 300 Revit model to the client. TruePoint's team of CAD technicians modeled the following details for the client: Pipe - 72,000 linear feet Conduit - 75,000 linear feet Duct - 11,000 linear feet Pipe modeled down to 1/2 inch in diameter.

A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations.

Location: Denver, Colorado Task: A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations. Our client was an architecture, planning and interior design firm specializing in commercial, institutional and academic design. Problem: Construction documents existed from the original build, but the client was unsure if they were up to date. Each building required a different scanning scope. The church and parish hall required complete exterior and interior documentation, while the school required only exterior documentation. The church required new design drawings and cost estimates from the firm before proceeding with renovations. Solution: In one day on-site, a GPRS/TruePoint Project Manager completed 359 scans with the Leica P50 ScanStation and the RTC360 laser scanner. The client required point cloud files, 2D CAD drawings, a 3D Revit model, and TruViews to understand the existing conditions of the buildings on campus. 2D CAD exterior elevations and floor plans of the church; and exterior elevations of the school were created for this project. An LOD 200 Revit 2021 3D model of the church was delivered with architectural/structural details, including columns, beams, walls, floors, ceilings, doors, windows, stairs, roof, pews, lectern, and alter. An LOD 200 Revit model was delivered of the school exterior. Benefits: Renovations are not new to this campus; they recently added an outdoor learning lab and eucharistic adoration chapel. They understand the value of accurate as-built data. The firm wanted to keep the historic craftsmanship of the church but provide modern updates. A quality point cloud created a reliable as-built BIM model of existing conditions with ¼ inch accuracy tolerance.

Brick Manufacturer Uses 3D Laser Scanning For Facility Upgrades Location: Shoemakersville, Pennsylvania Task: The demand for wood molded brick continues to grow as architects and designers utilize more brick in building designs. To keep up with this demand, our client, the largest molded brick manufacturer in the United States, is planning upgrades to its Shoemakersville, Pennsylvania facility. These upgrades include adding a second kiln to increase capacity and modernizing equipment to improve product quality. The client requested point cloud data, 2D CAD drawings, and a 3D Revit model to understand the existing conditions of the facility. Challenge: Our client was on a tight timeline. They requested as-built data, 2D drawings and a 3D BIM model of their 150,000 square feet facility in 12 business days. To complete the facility upgrades, they needed line, equipment, and tie-in points. Solution: 150,000 sq. ft. of space was 3D laser scanned in two days on-site with the Leica P50 ScanStation and the RTC360 laser scanner. 279 laser scans were taken to capture complete as-built data of the site’s structure, equipment, and MEP. Deliverable: GPRS delivered an LOD 200 design-intent architectural, structural, and MEP Revit Model, 2D AutoCAD floor plans and interior elevations, and an RCS point cloud file. MEP piping and conduit 2 inch and larger, HVAC ductwork, pumps, motors and equipment were 3D modeled to within ¼ inch accuracy. The 3D model will allow our client to discover any discrepancies between the design and existing conditions so they can make necessary adjustments before the facility upgrade begins. Added Value: Coordinating the work of designers with structural, MEP, and other construction teams is often difficult. Laser scanning provides a fast and accurate way to collect large amounts of site measurement data which can be used to expedite the retrofit design process. 3D scanning will help this client design to the actual as-built conditions, reducing clashes and change orders. Inaccurate data would slow teams down, increase the risk of miscommunication, and create prefabrication and installation problems that could lead to rework.

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.

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.

3D Laser Scanning

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.

GPRS’ task on this project was to laser scan and 3D model a façade and awning for a building addition under construction at an airport.

Location: Hebron, Kentucky Task: GPRS’ task on this project was to laser scan and 3D model a façade for a building addition under construction at an airport. After receiving the 3D model, the client requested a second mobilization to 3D laser scan and model the building’s awning. Challenge: GPRS’ client was fabricating and installing custom architectural panels for the building addition. The panels needed to fit perfectly and attach seamlessly with the already built substructure and window arrangement. For the second mobilization, awnings would also have to be made to adhere to the unique geometry of the awnings already in place at the airport. The size (25+ ft tall) and intricate detail of these panels made them very difficult to accurately measure using traditional measurement techniques. Solution: GPRS was able to quickly mobilize and scan the 17,000 sq. foot façade in one day. 59 laser scans were completed with the Leica P50 and P40 ScanStations from both the ground level and the elevated roadway that leads to the passenger drop-off zone. For the second mobilization, GPRS completed 23 scans with the Leica P40 ScanStation to gather precise data of the awning. Using industry standard registration methods, the scans from each dataset were seamlessly tied together to provide comprehensive detail of the façade and awning from all necessary vantage points. Deliverable: The final deliverables for this project consisted of an intensity map point cloud (.PTG format), Leica JetStream Viewer files (.LGS file), and a 3D model delivered in a .STP file format. All of which were mailed on a 1TB hard drive sent directly to the client’s office in Pennsylvania. Added Value: With the possession of an as-built, field-verified 3D model of the façade and awning, our client can confidently design and fabricate the necessary custom panels for their project. The client can reference the models during installation to troubleshoot on-site issues that may arise. Essentially, all guesswork is eliminated from the equation and the client can rely solely on the accurate measurements collected by Leica 3D laser scanners.

The target objects of data acquisition were structural features, including exposed columns and beams; and the architectural envelope of the audience area, including walls, floors, ceilings, doors, openings, railings, seats, floor and lighting. Problem: The client did not have accurate as-builts to plan and layout the new seating and understand the grade of the main floor and balconies. Manually measuring for this would have been time consuming and less accurate. Solution: 3D laser scanning will provide the client precise, as-built documentation of the historic theater, including floor slope, balcony and ceiling heights. GPRS captured point cloud data to generate a 3D as-built model from which the client could take measurements and locate key features that could be affected by the seating renovation. Benefits: GPRS’ in-house CAD technicians created a 3D Revit model for the client. Revit families were created for all the varying features so that each layer could be selected or de-selected depending on which portion of the model was being analyzed by the client. Accurate data facilitates timely and cost-efficient decisions. The 3D model will be crucial to plan for enhancements that are made to the space. This model could further be used to study the room acoustics and how adding/removing/changing objects would impact the reflection of sound.

Quote from GPRS Team Member: “The scanning and modeling teams worked around the clock, sometimes 7 days a week, to complete this project. The hard work paid off and we’re thrilled with the result – one of our most highly-detailed architectural 3D models to date.” - Nate Baker, GPRS Service Line Leader – 3D Laser Scanning Location: Philadelphia, Pennsylvania Task: GPRS Laser Scanning developed an as-built model to aid this client in converting a historic building into a luxury hotel. GPRS provided 3D scanning services for a 250,000 square-foot building, including the exterior facades, floors 1-4, basement, roof, penthouses and mechanical spaces. GPRS’ team of in-house architects, engineers and CAD Technicians delivered point cloud files, a 3D model, and TruViews to the client. Challenge: The client was challenged with acquiring highly detailed architectural data including walls, ceilings, floors, stairs, balustrades, colonnades etc., and structural data including exposed columns and beams to design the renovation. Due to the size of the building and the ornate features, traditional methods would have taken months to complete and would not have been as accurate or anywhere near as detailed. Solutions: The GPRS scan technician completed 1,680 laser scans in 15 days (an average of over 100 scans per day!) with a Leica P20 ScanStation. A 3D Revit model with varying degrees of LOD 200 and LOD 300 modeling was generated by GPRS’ engineers based on the client’s instruction. Some areas of the building, such as the main lobby and exterior facades, required finer modeling detail over 350. This was deciphered through several project scope conferences between GPRS and the client. Deliverables: GPRS delivered point cloud files (.rcs file formats), a 3D Revit model and TruViews to the client. GPRS worked closely with the project architect to review the model in real time utilizing BIM360 software for shared viewing of the model in its current state throughout the 2-month project. Added Value: 3D laser scanning aids the process of architectural design from the early stages of site documentation and conceptualization, to monitoring construction progress and verifying as-built accuracy. Aside from the benefits of quickly and accurately creating detailed as-built drawings of a site, the data acquired through laser scanning has continued value throughout the project's life. Laser scanning and modeling is exploding in the AEC industry. 3D laser scanning creates a smooth BIM workflow, from the acquisition of data to a polished 3D model. Scan to BIM services are becoming more popular as the need for intelligent 3D CAD models grows.

Caption: GPRS provided the client with the intensity map point cloud files and 3D mesh of the trees. Location: Austin, Texas Task: The client desired to laser scan three 100-year old trees and include them in the design plans for a new development. GPRS 3D laser scanned the trees and provided the client with intensity map point cloud files and a 3D mesh of the trees for reality capture. This was GPRS’ second phase of laser scanning for this client. Challenge: The client could not accurately capture the location, exact dimensions and detail of the three trees. They needed laser scanning services to include the trees in the design plan. It was important to capture the existing conditions without damaging the tree trunks or limbs. Solutions: GPRS’ Texas office used a Leica C10 ScanStation to capture the three trees and the surrounding area. Accurate 3D measurements were captured in a few hours on site in a fast and environmentally friendly manner. Laser scanners are non-contact, they scan from tripods on the ground up to 300 yards, keeping the environment untouched. Deliverables: GPRS provided the client with intensity map point cloud files and 3D mesh of the trees. This can be pulled into an existing Revit or AutoCAD model and aligned with the design plan, as well as be used in reality capture software. Added Value: GPRS incorporated the first and second mobilization into the same coordinate system which allowed the separate projects to be put on the same coordinates and relate the projects to one another even though they were captured at different times. This allowed the client to create their design model more accurately and preserve the 100-year-old trees. 3D information is invariant to lighting and shadow. As a result, significantly more data was acquired by laser scanning the tree, and much more accurately than hand measuring. Laser scanning services are the solution for capturing spatial data in a fast, efficient and highly accurate way.

Location: Fairmont, NE Task: GPRS mobilized to Fairmont, Nebraska to 3D laser scan a food grade corn processing facility. The target objects of point cloud data acquisition were tanks, silos, hoppers, conveyors, support cables, machinery, equipment, cleaning house and loading drive-thru. GPRS’ engineering team created an LOD 200 Revit model of the facility. The client also requested floor flatness analysis/contour mapping around several tanks. Challenge: The client needed accurate and precise detail of the facility in point cloud and model form, especially the congested areas. The client was concerned with differences in tank displacement; therefore, they requested tank farm slab elevation contours. Solution: An experienced project manager captured more than 160 scan locations with a Leica survey-grade laser scanner. The facility was scanned from the ground to capture the tanks, bins, silos, hoppers and discharge area under the 11 hoppers. The facility was 3D laser scanned at elevations with stair and elevator access to capture the spouting and conveyors at the top of each tank, silo and bin. Scanning was completed from the accessible roof to capture the equipment, cables and machinery present. The cleaning house was also scanned at multiple elevations to capture the entire room. The project manager increased the resolution and density of the point cloud to capture more detail in congested areas with small conduits, piping and flanges. With the millions of data points collected, GPRS’ engineering team could model this project with accuracy and precision. Concrete slab flatness can be quickly analyzed with laser scanning. GPRS engineers colored the cloud in respect to elevation to illustrate high or low points in the concrete. Deliverables: GPRS delivered unified point clouds in PTS file format, structured individual scans in E57 file format, a colorized point cloud (.rcs and/or .rcp file format) and JetStream Viewer files to the client. An LOD 200 Revit 2021 BIM model was created with the following elements: • Basic structural elements including exposed columns and beams • The general shape of 6 tanks with high detail at discharge locations and high detail on gates to conveyors • Rail spur within vicinity of tanks • Catwalks and equipment on tanks • Fall protection • Edge of adjacent building • Approximate grade GPRS delivered a graphical elevation map, contours and spot elevations for the requested tanks. This included AutoCAD, PDF, and Civil 3D files to generate contours around the tank farm. Added Value: GPRS works closely with each client to ensure their needs are met. Point cloud files were immediately uploaded to Cintoo for the client’s use. They were able to add annotations or tags to anything they might want modeled. To minimize modeling costs, all modeling is done as a “best fit” method, utilizing solids overlaid on the point cloud data. To verify the spot elevations, GPRS also provided tank roof elevations shown colored by point cloud elevation.

The area was recently renovated, and the objective was to capture MEP features to create an accurate as-built survey for the client. GPRS’ Project Manager used a Leica P40 ScanStation to capture 3D point cloud data and GPRS’ in-house engineers created a 3D CAD model. Challenge: The client wanted to complete the laser scan after the space had been framed in, but before the ceiling grid and tiles were installed. This gave the client a very limited window of time to capture the above ceiling piping. They wanted to quickly and accurately capture all MEP components and pipes, so they could install the ceiling and begin to populate the space. Solutions: GPRS maintained constant communication with the client to schedule the scanning just before ceiling grid was installed. With just a few days’ notice, the Project Manager mobilized to the site. GPRS’ experienced technician could ensure that 3D laser scan technology would completely and accurately capture the as-built site conditions. Laser scanning was completed while other contractors continued their work, and complex areas were scheduled during the hours when contractors were off-site. Deliverables: GPRS provided the client with Autodesk Recap files and Black and White Leica TruViews. Also, using preliminary EdgeWise extraction, GPRS engineers provided an AutoCAD .dwg file to the client. Added Value: The scan technician worked during off-peak times, which expedited GPRS’ time on site. Additionally, GPRS’ engineers are trained and experienced in numerous software applications and can create custom deliverables for each client quickly. In this case, ClearEdge 3D Edgewise software was used to process piping and quickly create a 3D model.

Header: A GPRS Case Study: 3D Laser Scanning a Grain Elevator in Michigan Location: Near Saginaw, Michigan Task: GPRS provided high-definition laser scanning services at a grain elevator in Michigan to capture the as-is conditions of the site. The client needed an accurate representation of the structural features to perform maintenance upgrades. They wanted specific documentation of the bucket elevator legs, fill conveyor bridges and tower supports. Challenge: This was a complex site that included the grain elevator, silos, bins, tanks, conveyors and bridges. The area laser scanned was near 180,000 square feet with heights over 110 feet. Traditional means of measuring would be difficult, costly, time consuming and potentially hazardous. Solutions: The Project Manager completed laser scanning in two days utilizing the Leica C10 and Leica P40 laser scanners. Varying the position of the scanners on the ground and between silos, the technician was able to capture this complex site from a variety of angles. Additionally, the Project Manager occupied elevated positions and tied those scans to the scans performed at grade. All the scanning could be safely performed from a distance without climbing the structure and without the need for renting lifts or scaffolding. Deliverables: The client received Autodesk Recap files of the scans (.rcs file format), black and white TruViews of the site, a 3D AutoCAD Model of the site, and section and plan views of the model laid onto the point cloud data with callouts. Added Value: GPRS’ CAD technicians communicated directly with the client to focus on key areas for detailed modeling to model exactly what was needed to keep costs down by avoiding unnecessary modeling effort. Using advanced extraction techniques and specialized software, GPRS was able to accurately represent structural features and deliver these to the client.

Case Study: TruePoint 3D Laser Scans Hard Rock Stadium For Mixed Reality Super Bowl Feature We would like to thank The Famous Group, the Miami Dolphins and the Hard Rock Stadium for allowing us to be a part of this project.” - Ryan Hacker, President of TruePoint Laser Scanning Location: Hard Rock Stadium, Miami, Florida Task: TruePoint 3D laser scanned the Hard Rock Stadium for use in a mixed-reality experience during the 2020 Super Bowl on February 2. Mixed reality is a blend of physical and virtual worlds that includes both real and computer-generated objects. The two worlds are "mixed" together to create a realistic environment. Challenge: It was important to the client that the existing spatial layout was captured with great accuracy. When generating the mixed reality experience, computer-generated objects must precisely interact with the physical environment to sell the realism. Solution: The upper and lower stands, field topography, LED display screens, LED ribbon around stadium, two Hard Rock Stadium signs and roof structure were documented with a survey-grade Leica P40 ScanStation. In two days onsite, 172 laser scans of precise point cloud data was captured. TruePoint’s team of in-house engineers quickly generated a 3D Revit model for the client. The client planned to use Autodesk Maya, a 3D computer animation, modeling and rendering software to create an augmented reality (AR) simulation. Deliverables: TruePoint delivered point cloud files in .rcs format, a 3D Revit Model, and a FBX file. The client was also able to view the model progress using Autodesk A360, a web-browser application that allows engineers and project teams to work together more easily in an online workspace. Added Value: “Everything we do at TruePoint Laser Scanning is highly custom. This client wanted portions of the stadium modeled in LOD 100 and portions modeled in LOD 300. Our deliverables were customized, so the client is only paying for what they need,” Aaron Hunt, Lead Technical Manager.

GPRS provided 3D laser scanning and modeling services for a power plant in Ann Arbor, Michigan.

Location: Ann Arbor, Michigan Task: GPRS provided 3D laser scanning and modeling services for a power plant in Ann Arbor, Michigan, which generates and processes four main services: steam, electricity, compressed air and domestic hot water. The objective was to as-built survey the 5-level building, basement, exterior facades, rooftop areas, electrical switch gear rooms, vaults and interstitial space below the control room. GPRS generated a 3D model in Bentley Microstation for the client’s use. The model included all civil, structural, electrical and mechanical features, including piping and conduits ½" in diameter and larger. Challenge: The client needed to accurately document existing conditions. Due to the vast space and density of piping, it would have been much more difficult and time consuming to accurately depict the location of pipe runs, structural features and other details in the plant manually. It would have also been difficult and unsafe to capture overhead and structural features without the use of a lift. Solutions: Utilizing several scan technicians and multiple Leica laser scanners, including the Leica P-40, P-20, and C-10 ScanStation, GPRS was able to occupy existing plant benchmarks and orient the data to survey control. GPRS’ scan technicians captured full color panoramic photographs at each scan location with the on-board camera. GPRS completed over 1,200 individual scans for this project due to the density of the piping. Deliverables: GPRS’ team of in-house CAD technicians provided Microstation POD files, full-color TruViews and a Bentley Microstation V8i 3D model. Added Value: GPRS communicated directly with on-site personnel at the power plant and participated in daily work briefings to ensure compliance with plant safety protocol. Additionally, GPRS’ CAD technician visited the site with the scan technician, utilizing cutting edge methods to conduct in-field verification and quality assurance review of the 3D model on tablets in real time using both virtual reality and augmented reality methods.

3D Laser Scanning

GPRS provided laser scanning services to capture data from a staircase and railings to generate a 3D model in STP file format. The target objects of acquisition were the staircase features including treads, rails and rail hangers. The 3D model was needed to create custom drawings to prefabricate an irregular railing.

GPRS is experienced in 3D laser scanning spiral staircases.

Location: New York, NY Task: GPRS provided laser scanning services to capture data from a staircase and railings to generate a 3D model in STP file format. The target objects of acquisition were the staircase features including treads, rails and rail hangers. The 3D model was needed to create custom drawings to prefabricate an irregular railing. Challenge: It was difficult for the client to accurately make three-dimensional measurements of staircase and railing using conventional tools. Manually trying to take enough measurements in the X, Y, Z axis to comprehensively and accurately model the unique shape and contours would have been tedious and nearly impossible. Solutions: High resolution point cloud data was collected by an experienced scan technician in 20 scan locations and four hours on site. Accurate measurements of all parts of the stairway, including the whole step surface, balustrade, handrails and adjacent floor and wall surfaces were quickly captured. Deliverable: GPRS’ in-house engineers delivered intensity map point cloud files, 3D model in STP file format and TruView’s (3D photographs overlaid on top of the point cloud data) to the client.Added Value: The GPRS scan technician was met on site by an Italian-based design firm to discuss using the 3D model to generate design specs. In this case, the client was interested in dimensions of the railing for fabrication. 3D laser scanning generates point cloud data and engineers can summarize the data into a 3D model. Every dimension on the staircase can be determined quickly and accurately. Another benefit of laser scanning includes being able to immerse a viewer in the virtual scene without the need for a site visit. 3D laser scanning is a powerful tool for capturing measurements where precision and accuracy are critical.

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.

GPRS 3D laser scanned each area to capture the existing conduit, post-tensioning, rebar plan and sleeves prior to the slab being poured.

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. GPRS’ nationwide team of scan technicians that can mobilize to any site quickly. Our experience and long-term client commitment make us a great partner for your 3D laser scanning needs. 3D high-definition surveying has proven to be a quick, accurate, and versatile tool for architects, engineers, BIM managers, general contractors, and construction managers. It is ideal for adaptive reuse or renovation projects. In this case, GPRS provided the client with invaluable information that allowed them to assess the site from their office before the concrete slab was poured. 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.

John Glenn International Airport – Columbus, Ohio Airport Entrance Upgrades Requires 3D Laser Scanning ‍ TASK: GPRS provided 3D laser scanning services for John Glenn International Airport in Columbus, Ohio. The client was upgrading the existing airport entrance. Renovations included the installation of a prefabricated ceiling panel system and new doors. The primary objective of the laser scan was to capture the ground, curbs, ceiling beams, and related structural features to design and prefabricate the upgrades. ‍ CHALLENGE: The client had a 60-day window to complete renovations, and no in-house engineers. The airport entrance did not match the architectural drawing; the ceiling structure was sloped where the drawings showed it level, and differing beam heights and widths between two levels of the airport created additional challenges. They needed accurate as builts to tie the upgrades to the existing structure and align with the camber of the structure. The client also had to deliver precise measurements to the ceiling panel system prefabricator and to provide the builders of the custom doors precise measurements on entryways. This would minimize any assumptions that could lead to field changes and schedule delays during construction. ‍ SOLUTION: The airport, which serves 7 million annual travelers, needed to remain in operation with little to no interruption of services. So, 3D laser scanning was completed at night during low passenger activity periods, so the airport could remain in operation. The GPRS Mapping & Modeling Team worked closely with the client to create maps and models to expedite components and minimize inaccuracies. 2D CAD drawings, and a 3D BIM model were delivered, which eliminated field adjustments and delays during renovations. The laser scan data also helped the client to plan how the new entrance would tie into the existing entrance, while taking into account all of the field variables.

Complete subsurface mapping and millimeter-accurate aboveground measurements for a top-down, 360° visualization of a hospital wing and parking area to support a hospital expansion.

The addition is designed to occupy an existing parking lot for hospital employees, patients, and visitors. GPRS performed utility locating, video pipe inspection, and 3D laser scanning to create a comprehensive map and 3D model of the medical center’s infrastructure, both above and below ground.

TASK: Complete subsurface mapping and millimeter-accurate aboveground measurements for a top-down, 360° visualization of a hospital wing and parking area to support a hospital expansion. PROJECT APPLICATION: Rudolph Libbe, a longtime GPRS client and partner, oversaw the construction on the expansion of a northwest Ohio medical center. The addition is designed to occupy an existing parking lot for hospital employees, patients, and visitors. GPRS performed utility locating, video pipe inspection, and 3D laser scanning to create a comprehensive map and 3D model of the medical center’s infrastructure, both above and below ground. PROBLEM SOLUTION BENEFITS n Rudolph Libbe received millimeteraccurate laser scan data and an integrated 3D BIM model to precisely design and plan the building addition during preconstruction. n Non-destructive utility-locate methods reduced the number of unknown utilities and obstructions for the design and construction teams. n GPRS’ as builts allowed Rudolph Libbe to plan the new foundation and identify areas where further investigation would be warranted to prevent design and utility clashes. n With comprehensive field services provided by GPRS, Rudolph Libbe saved time and money on change orders, and eliminated subsurface damage during the construction process. With parts of the medical center’s campus dating back to the mid- 1800s, inaccurate as built data and unknown subsurface obstructions could jeopardize construction planning. n It was imperative that the proposed locations of the structural foundation and planned utilities coordinated with the existing conditions. n Rudolph Libbe desired 3D as builts to plan and complete the building addition, such as structural and utility tie-in information. n Traditional exploration methods typically include “soft” excavation methods over the entire building footprint. This option is expensive, time consuming, and requires tremendous coordination. GPRS utilized ground penetrating radar (GPR) and electromagnetic (EM) locating to map the hospital’s utilities. n Video pipe inspection (VPI) recorded the precise location and condition of the facility’s sewer lines, detailed in a NASSCO-certified report. n 3D laser scanning documented as built site data and utility maps to create 2D CAD drawings and a 3D BIM model for virtual design and construction. n GPRS participated in coordination meetings with construction and design team members. NO ONE HAS GONE TO THIS EXTENT TO MAP A SITE ABOVE AND BELOW GROUND. IT WAS IMPERATIVE THAT RUDOLPH LIBBE HAD ACCURATE AS BUILT SITE DATA AND UTILITY MAPS WITH CRITICAL STRUCTURAL AND UTILITY TIE-IN INFORMATION.” JAIME ALTHAUSER | FIELD SUPPORT DIRECTOR, GPRS

3D Laser Scanning

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.

The data GPRS collects can be used to develop the utility portion of a conceptual site model (CSM) to visualize migration routes, communicate with stakeholders, make informed remediation decisions, and protect the team on site and the environment.

A gas station requested utility locate and as built data to document the existing conditions for site upgrades and to develop an emergency response plan for potential leaks. Accurate 2D utility locate maps, a 3D BIM model, and a conceptual site model (CSM) were created of the gas station, underground storage tank system, and surrounding utilities.

A Michigan gas station requested utility locate and as built data to document the existing conditions for site upgrades and to develop an emergency response plan for potential leaks.

Task: A gas station requested utility locate and as built data to document the existing conditions for site upgrades and to develop an emergency response plan for potential leaks. Accurate 2D utility locate maps, a 3D BIM model, and a conceptual site model (CSM) were created of the gas station, underground storage tank system, and surrounding utilities. Problem: The gas station lacked as built site information required for compliance with environmental regulations, essential to plan for site upgrades, and necessary to take prompt corrective action in the case of an emergency. The client did not have an accurate conceptual site model (CSM) to understand and interpret contaminant fate and transport in the subsurface. Solution: GPRS Project Managers used state-of-the art equipment to perform ground penetrating radar (GPR), electromagnetic (EM) locating, video pipe inspection (VPI), leak detection, 3D laser scanning, and drone photogrammetry services at the gas station. The GPRS Mapping & Modeling Team delivered accurate as built and utility location data in point cloud, 2D maps, 3D BIM model formats, to help eliminate guesswork from decision making, and prevent time-consuming and dangerous mistakes and the costs associated with them. The gas station received access to millimeter-accurate information to efficiently plan work and drill safely. Locating underground storage tanks, including their depths, can help the station owner detect unusual fluctuations in fuel levels and assess any potential leak faster. Detailed site maps can help to communicate the location of a leak, the most likely paths and extent of horizontal and vertical delineation, and to plan assessment and mitigation efforts. Benefits: Infrastructure location and mapping are vital before conducting any construction or subsurface work like soil boring, or coring concrete to drop vapor pins – to eliminate clashes and utility strikes and keep workers and the community safe. Comprehensive site data is essential for the early detection and management of petroleum leaks at a gas station, to help minimize environmental damage and ensure the safety of employees and the surrounding community. GPRS as built maps and models provide accurate information to avoid hitting a UST or system component, and to avoid a utility strike when sampling soil. The GPRS SiteMap® mobile app securely stores utility data, geolocated and layered, and securely accessible for the station stakeholders to share with those who may need it. The data GPRS collects can also be used to develop the utility portion of a conceptual site model (CSM) to visualize migration routes, communicate with stakeholders, make informed remediation decisions, and protect the team on site and the environment.
