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. Added Value: The use of laser scan technology has resulted in accurate and efficient data collection, true as built documentation, cost savings due to improved design accuracy, and improved project visualization and collaboration.

Brick Manufacturer Uses 3D Laser Scanning For Facility Upgrades

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.

Restoring Frank Lloyd Wright’s Unity Temple

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 Scan Corporate Office HVAC and Mechanical Systems

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.

LiDAR Survey Dimensions of a 6-Story Building

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.

3D Laser Scanning Building Façade and Awning

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.

3D Laser Scanning Aids In Hotel Renovation

A hotel developer plans to invest $30 million to renovate a 200-room hotel in downtown Toledo, Ohio. Case Study: 3D Laser Scanning Aids In Hotel Renovation Location: Toledo, Ohio TASK: A hotel developer plans to invest $30 million to renovate a 200-room hotel in downtown Toledo, Ohio. GPRS performed laser scanning services to aid this client in the renovation. GPRS 3D laser scanned the exterior elevation, basement, main lobby level, 2nd floor and elevator shaft – more than 30,000 square feet of space. All structural and architectural features were captured as part of the scan. PROBLEM: No accurate as-built drawings existed. It would have been difficult, costly and time consuming to manually measure the 19-story building. The developer was not local, making transportation and lodging an added expense. Safety was also a concern, as the building was partially demolished and contained asbestos. SOLUTION: GPRS quickly mobilized to the site and captured the existing conditions of the hotel. Using a P40 survey-grade Leica ScanStation, the local GPRS Project Manager tied the data to survey control, achieved 2-4mm accuracy, and mitigated movement, ensuring level scans. The client received .rcs Intensity Map Point Cloud files, 2D AutoCAD Floor Plans, 2D Point Cloud Sheets, a 3D Revit 2017 LOD 100 Model and TruViews. To save costs and expedite this project, only the unique floors of the hotel were laser scanned. Capturing the basic structural and architectural features will immensely help the architect in planning the hotel renovations. Laser scanning quickly captured precise data while avoiding the risk of the unsafe environment. GPRS collected all building information, eliminating the need to return to the site for additional measurements. For 3D laser scanning of hotels and other resort properties, contact GPRS.

Oil Tank 3D Laser Scan

3D laser scanning by GPRS for an oil tank replacement. Case Study: Oil Tank 3D Laser Scan Location: Emporia, Kansas TASK: GPRS provided terrestrial-based 3D laser scanning services for a 25' x 25' x 30' oil tank near Topeka, Kansas. The objective was to capture the existing conditions of the tank, piping, flanges, nozzles, structural steel, pipe supports and grade. PROBLEM: The client was upgrading the oil tank and needed 3D laser scanning to plan for the removal and replacement. For tank replacement, the true shape and condition of the tank can be critical for ensuring that the new design fits the existing conditions; hence reducing costly delays or rework. All piping, nozzles and structural steel around the tank was reality-captured so the new tank could be designed with proper fit and without interruptions to the unit. SOLUTION: 3D laser scanning provides a way to quickly and accurately obtain the existing condition information. The exact dimensions of a tank can easily be determined to ensure that fabrications match the existing structure. In less than 5 hours on site, the GPRS Project Manager captured the as built conditions of the existing tank and nozzles. Once the point cloud was registered, GPRS Mapping & Modeling CAD technicians delivered the point cloud data for the client to incorporate into their design model. GPRS delivered Intensity Map Point Cloud files, RCS Files and PTG Files to the client. BENEFITS: GPRS uses Leica Laser scanners, which can also capture images to further enhance the collected data. These images, called TruViews, were provided to the client and offer factual record of the areas inspected. GPRS is an experienced 3D laser scanning company. Our knowledgeable Project Managers confidently scan complex jobs with extreme safety requirements. For this job, the technician used an intrinsically safe laser scanner, since any spark would cause an explosion for this particular tank farm. Delivering the point cloud data gives the client the ability to do clash detection for interferences, saving them time and money in the field.

3D Laser Scanning A Theatre To Generate A 3D Model

GPRS 3D laser scanned a historic theatre to generate a 3D Revit model for seating renovations. Case Study: 3D Laser Scanning A Theatre To Generate A 3D Model Location: Philadelphia, PA Task: GPRS laser scanned a historic theater, including the main floor, three balcony levels and box seats to generate a 3D Revit model for seating renovations. 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.

Caption: GPRS completed long-range, high-resolution laser scanning of a historic building in Philadelphia. 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.

GPRS Provides Point Cloud and 3D Mesh of Trees

Meta Title: GPRS Provides Point Cloud and 3D Mesh of Trees Meta Description: GPRS 3D laser scanned and provided the client with intensity map point cloud files and a 3D mesh of trees for reality capture. Header: A GPRS Case Study: GPRS Provides Point Cloud and 3D Mesh of Trees Images: Link: https://www.gp-radar.com/services/3d-laser-scanning Alt Tag: 3D laser scan data of a tree. Caption: Accurate 3D measurements were captured in a few hours on site in a fast and environmentally friendly manner. Link: https://www.gp-radar.com/services/3d-laser-scanning Alt Tag: Revit model of trees. Caption: The deliverables can be pulled into an existing Revit or AutoCAD model and aligned with the design plan. Link: https://www.gp-radar.com/services/3d-laser-scanning Alt Tag: 3D mesh of trees. 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.

Verifying Accuracy Of Structural Steel With 3D Laser Scanning

“We greatly appreciate TruePoint’s willingness to work in tandem with the other trades onsite and schedule their work around construction obstacles." -- R. Serra, Architect Location: Staten Island, NY Task: Structural steel construction was underway on a $180 million, 127,000 sq. ft. shopping center designed to house 60 retailers. The client requested 3D laser scanning services to capture point cloud data from the structural steel and generate an LOD 200 AutoCAD model to verify the accuracy of existing 2D drawings. TruePoint was tasked with 3d laser scanning the site and capturing all structural elements including exposed columns, beams and floor.

3D Laser Scanning Services Used for Manufacturing Facility Expansion

3D Laser Scanning Services Used for Manufacturing Facility Expansion Project Manager Insight: Our client planned this manufacturing facility expansion in two phases. The first phase will expand production from five to seven days a week. The second phase will add an additional packaging line. -- Karl Hofmeister, TruePoint Project Manager Location: Richmond, Indiana Task: A pet nutrition manufacturer was expanding its facility to increase the production of current products and add an additional packaging line. The 30-year-old company planned to invest $17.5 million in this expansion. TruePoint Laser Scanning conducted an as-built site survey and created a 3D BIM model for the facility expansion. TruePoint captured approximately 50,000 square feet of the dry mixing facility spanning 5 levels, including a meat slurry room, a batching area, an extruder room, a hammermill room and several mechanical and electrical rooms. TruePoint captured precise point cloud data of all architectural and structural features, equipment, conduit and piping. Challenge: No as built plans existed for the facility. The plant was complex, capturing the existing spatial data of the machinery, conduit and piping in a high level of detail was important to the plant engineers. There were many silos and machinery that needed to be worked around and could obstruct the view. The client was making a large investment in capital and equipment and needed reliable data to expedite the installation without rework. Solution: In two days on site, TruePoint’s experienced project managers 3D laser scanned the manufacturing facility with the Leica P50, Leica P40 and RTC 360 laser scanners. TruePoint’s in-house modeling team built an information-rich 3D BIM model for the client.

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.

Location: Cincinnati, OH Task: GPRS 3D laser scanned 40,000 square feet of office space on the 6th floor of a building in Cincinnati. 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.

This was the first time we have used GPRS modeling services, and the 3D model your team created was outstanding. We were very impressed with the level of detail and quality of the model, the speed in which your team was able to create it, and all aspects of communication during the process.” TLF Engineers’ Senior Project Engineer Seth A.R. Gressley, P.E. Location: Clymers, Indiana Task: GPRS was hired by TLF Engineers to 3D laser scan the exterior cooler area at the southeast corner of The Andersons’ Indiana Ethanol Plant and create a 3D BIM model for process improvements. Project Application: 3D laser scanning collects accurate agricultural as-built data safely from the ground, delivering precise site layout and dimensions for design planning and analysis. Problem: The Andersons’ planned to make process improvements over the next five years to improve operational efficiency and lower plant emissions TLF Engineers needed up-to date as-builts of the plant infrastructure to design upgrades to equipment and production lines Precise details were required for a 2,500 sq. ft. area, including the existing cooler, drop box, dust collectors, platforms, cooler, stack, and ductwork Solution: 3D laser scanning captured a colorized point cloud with 2-4mm accuracy and HDR images in less than 3 minutes per scan location The point cloud was used to develop a 3D BIM model at a very high level of detail with precise architectural, structural, and MEP features TruView 360° photographs provided a virtual site tour, allowing the client to take basic dimensions, estimate clearances, and markup the project site. Benefits: Comprehensive data of existing structure and equipment was crucial to plan process improvements and equipment optimization With a detailed 3D BIM model, the engineering team was able to virtually design the facility layout, retrofit equipment and optimize workflow Updates improved ethanol yield and quality, increased production efficiency, and lowered plant emissions

GPRS 3D Laser Scans Hard Rock Stadium For Mixed Reality Super Bowl Feature

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.

Providing Safe Urban Power Distribution System Installation

3D Laser Scanning Michigan Power Plant

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 a Spiral Staircase

3D Laser Scanning a Historic Church for Restoration

3D Laser Scanning Before Concrete Pour Saved Client Thousands

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.

Protecting College Campus’ Wastewater Infrastructure During Excavation

Intelligently Visualizing the Built World for Rudolph Libbe Hospital Addition

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

Laser Scanning Manufacturing Facility for Capital Improvement Project

Accurate PT Cable Layout Critical to Construction

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.

3D Scanning For Next Generation Building Modernization

By involving laser scanning on the front end of the project the client will pay for the laser scanning services by reduced change orders, rework, and associated delays by having all of the necessary information upfront. INDUSTRY Office & Commercial Buildings SERVICE 3D Laser Scanning & 3D BIM Modeling ASK 3D laser scan 350,000 sq. ft of office space at the Carnival Cruise Lines Corporate Headquarters in Miami, Florida to develop a LOD 200 Revit model showing basic architectural features, including walls, doors, windows, and ceilings to begin construction renovation space planning and plot furniture placement. PROJECT APPLICATION Behind every successful renovation project lies detailed design plans, budget and timeline estimates, and an expert construction team. Laser scanning allows design and construction teams to understand exactly what’s in an existing space by providing millimeter-accurate as-builts. TASK GPRS 3D laser scanning services provide 2-4mm accurate existing conditions site documentation for efficient planning, design, and construction. Once the site was laser scanned, the GPRS Mapping & Modeling Team created a geometrically accurate 3D building information model (BIM) model of the site. PROBLEM • Carnival Cruise Lines plans to redesign existing office workspace in the Miami, Florida headquarters. • The company seeks to develop a workspace that is aligned with core organizational values such as collaboration, transparency, diversity, and inclusion. • A strict deadline required a rapid capture of as-built information. • Secondary goals include improved building efficiencies and modernization of the space to meet the needs of current and future employees. SOLUTION • Laser scanning provided accurate and detailed information, plus the ability to quickly create a 3D BIM model. Manually pulling hand measurements would prove hugely inefficient in a space of this size. • After laser scanning the North and South Tower, GPRS produced a LOD 200 Revit model showing basic architectural features (walls, doors, windows, and ceilings) of the entire area. BENEFITS • GPRS provided a LOD 200 Revit model that can be used along with the 3D JetStream viewer files as a means of showcasing the existing conditions to their client throughout the duration of their project. • By involving laser scanning on the front end of the project the client will pay for the laser scanning services by reduced change orders, rework and associated delays by having all of the necessary information upfront.

GPRS Utility Locate and 3D Laser Scan for a Gas Station

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.

Using 3D Laser Scanning For Facility Design Modification

CASE STUDY LOCATION Bowling Green, Kentucky TASK: When plant engineers at a pet food packaging facility needed to make modifications, they asked TruePoint Laser Scanning to provide as built documentation and a 3D model to plan retrofits to the existing structure. The project site consisted of 140,000 sq. ft. of interior space. Approximately 100,000 sq. ft. of this was single-story warehouse space, consisting of a central palletizer, semi- truck loading bays and temporary material storage. The remaining 40,000 sq. ft. contained 7 levels of elevated platforms containing product packaging equipment. TruePoint captured all architectural and structural features, equipment, conduit and piping. PROBLEM SOLUTION BENEFITS n By using laser scanning instead of traditional survey methods, TruePoint saved this client thousands of dollars in field survey work and drafting time, and provided greater detail than what would have otherwise been possible. With an accurate, comprehensive data set, plant engineers were able to complete virtual interference checks, avoiding design rework costs. n In two days on site, TruePoint’s experienced project managers 3D scanned the 140,000 sq. ft. area with millimeter accuracy. 523 scans were taken with the Leica P50 and RTC 360 laser scanners. This project was scanned on the weekend to avoid disruption to production. n After proper data registration, TruePoint’s in-house modeling team built an information-rich 3D BIM model for the client. TruePoint’s experienced team has optimized workflows for importing data, registration, creating deliverables, quality checks and transferring data to clients. n No as built plans existed for the facility. The plant was complex, capturing the existing spatial data of the conduit and piping in a high level of detail was important to the plant engineers. n There were silos and other pieces of large equipment that would be difficult to measure precisely using traditional or manual measuring techniques. /// GPRS LASER SCANNING SERVICES ///// 3D LASER SCANNING CASE STUDY: USING 3D LASER SCANNING FOR FACILITY DESIGN MODIFICATIONS “IT’S HARD FOR ME TO IMAGINE HOW THIS PET FOOD PACKAGING FACILITY COULD HAVE BEEN DOCUMENTED WITHOUT 3D LASER SCANNING.” TRUEPOINT PROJECT MANAGER
