Promethean Builders Phillip's Point 777 Flagler Case Study 3D BIM Model for Office Renovation The Bottom Line: Large-scale renovation projects involve a massive amount of data, planning, and coordination. GPRS delivered a 3D BIM model in phases, allowing the General Contractor to focus on specific sections of the project at a time, ensuring an accurate and quality design before moving on to the next phase. Industry: Commercial Office Space Service: 3D Laser Scanning, Mapping & Modeling Location: West Palm Beach, Florida PM Insight: A 3D BIM model delivered precise data to guide project decisions, maximize efficiency, and minimize rework. 3D laser scanning delivered a level of detail that is critical to accurate design planning, preconstruction, and field execution. Task: GPRS partnered with Promethean Builders to 3D laser scan Phillip's Point East and West Commercial Office Towers in West Palm Beach, Florida to capture as-built data of 637,180 square feet of space and generate a 3D BIM model for extensive building renovations. Built in 1985, the property sits on 4.3 acres, contains two towers, the East Tower totaling 255,523 square feet and West Tower totaling 416,636 square feet, 40,000 square feet of retail space on the ground floor, and two parking garages. Problem: This was a large-scale renovation of two commercial office towers that required several mobilizations of laser scanning to capture existing site conditions. Survey control was important in this project to ensure that the 3D laser scans precisely fit together and were geographically accurate. The client requested that the 3D BIM model be delivered in phases to manage the complexity of this project. Structural, mechanical, electrical, and plumbing engineering schematic design plans were required for this extensive renovation. Solution: The GPRS Project Manager created a thorough plan to capture comprehensive existing conditions documentation while working around trades on site, including determining the scanner set-up locations and site workflow, to properly coordinate and estimate the time needed on site. GPRS coordinated with the client’s survey team to establish project survey control prior to laser scanning to ensure accuracy of the laser scan data. This process helped tie the laser scan data into an established coordinate system, capture measurements with high precision, and ensure that the scan data was georeferenced and properly aligned. GPRS CAD technicians utilized Autodesk Construction Cloud (ACC) to centralize project information, allowing multiple technicians to work inside the model at the same time. The team was able to send the 3D BIM model in phases to hit client deadlines. The BIM model was used to detail specifications for the HVAC systems, ensuring a precise design, coordination across disciplines, clash detection, and accurate construction timelines. Benefits: The Leica P-Series and RTC360 LiDAR laser scanners captured every detail of the 637,180 square feet of space with 2-4 millimeter accuracy in a point cloud file, delivering precise architectural, structural, and MEP system layout and dimensions for renovation planning. ACC provided a document management system that saved a web-based record of every single project file and submittal. It allowed the GPRS CAD technicians to archive old submittals and track progress. Working with tools like Revit and Navisworks within ACC immediately synchronizes designs, so if the General Contractor revises information, the changes can be transmitted to the field, and the jobsite is always working from the latest information.

PROBLEM The client was in need of valid, detailed documentation of the existing layout. The amount of current equipment and piping in the space made it difficult for the architects and contractors to know the precise location to install new lines and equipment. In challenging manufacturing facilities which house complicated, congested piping structures, clash detection via Building Information Modeling (BIM) becomes a vital planning step. The BIM helps identify clashes during the design stage, virtually eliminates design changes, and reduces costs and project delays. Solution Using a survey-grade Leica laser scanner, the GPRS team completed 254 scans during two days on site. The Scan-to-BIM services will allow the client to accurately design the new pipe runs and install the new mixing station with confidence and ease. The 3D model will also be useful for any future projects that may be needed in the same area, as well as on-going operations and maintenance. ‍ Benefits 3D laser scanning eliminates potentially costly guesswork with documentation. The client had a general idea of where the tank and piping was to be installed, but with accurate scans and models of the entire processing room, they possessed accurate documentation of the entire space. This eliminates the guesswork, allowing them to accurately plan a layout and tie into the existing systems avoiding clashes with existing the piping and equipment.

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.

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.

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.

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. Deliverable: The deliverables created for this project included an intensity map Autodesk Recap point cloud (.rcs file), LGS/JetStream Viewer files and a Revit 2019 LOD 300 3D model. The information-rich 3D model included: Basic structural elements including exposed columns, beams and structural bracing. Basic architectural elements including walls, doors, windows, floors and ceilings. Mechanical, electrical and plumbing piping 2" in diameter and above, showing valves on all pipes that were 2" and larger. Conduit runs were modeled as solid blocks. MEP Equipment including pumps, electrical boxes, silos and HVAC ductwork. Added Value: TruePoint 3D laser scanned another facility for this client earlier this year. We were contacted to provide accurate site data to plan for this facility expansion. 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.

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.

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

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.

Pinpoint the source of contaminated groundwater infiltration so the customer could mitigate it before it reached the outfall point

GPRS pinpointed the defect in the storm sewer line that was allowing for inflow of contaminated groundwater so that the system manager could repair it and stem the flow of contaminated water at the outflow point, to protect the waterway, the environment, and public health.

The client requested us to locate and inspect the storm sewer system, including potential laterals at a site with known soil and groundwater contamination • There was no known existing condition documentation or maps of the storm sewer system or potential laterals • The client identified higher contaminant concentrations at the storm sewer outfall than at upstream catch basins • An outfall is where a sewer line discharges into a body of water, so it is vital to the environment and public health to mitigate inflow contamination Solution • GPRS VPI services located and mapped all storm sewer lines, laterals, and flow direction to the outfall • We did this utilizing lateral launch cameras, robotic CCTV crawlers, and push cameras • We identified the area of groundwater intrusion into the storm sewer system, which assisted in determining which portion of the system needed to be repaired to stem the contaminant inflow before it reached the outfall Benefits • On Time: Due to our rapid response, we kept the project moving, reducing downtime • On Budget: GPRS protected the client's budget by preventing expensive and unnecessary excavations • Safety: GPRS provided accurate storm sewer locations and depths as well as the area the contaminated groundwater intrusion was identified. So the client was able to dig safely, repair the line, and eliminate the contaminated groundwater infiltration to eliminate risk to public health and the environment • Reputation: By preventing the client from using a trial-and-error approach, they can quickly deliver their results to their customers to alleviate concern and protect public health • GPRS provides complete NASSCO-certified Video Pipe Inspection Reports that provide video, photos, and reporting of each pipe defect discovered and its severity to help customers plan, repair, and better maintain their sanitary and storm sewer systems

The Famous Group was able to create a mixed reality experience that included an enormous virtual panther skulking through the stadium and onto the Jumbotron, delighting the 70,000 fans in attendance, thanks to the accurate scans, models, and meshes provided by GPRS

GPRS 3D laser scanned The Bank of America Stadium and the Gentle Giant panther statue for The Famous Group and the Carolina Panthers to create a mixed-reality experience for the home opening football game vs. the New York Jets

GPRS 3D laser scanned The Bank of America Stadium and the Gentle Giant panther statue for The Famous Group and the Carolina Panthers to create a mixed-reality experience for the home opening football game vs. the New York Jets. GPRS delivered a 3D mesh model to assist in the creation of this mixed-reality experience.

Problem • To sell the realism of mixed reality, computer-generated objects must precisely interact with the physical environment • As-built information and a 3D model of The Bank of America Stadium did not exist Solution • In 1 ½ days on site, using a Leica P40 ScanStation, point cloud data of the interior field, stadium bowl, seating, and upper rigging area was captured • To give the panther virtual objects to climb on and interact with, CAD technicians used the point cloud data to create a Revit 2021 LOD 200 3D model of the stadium • The Gentle Giant panther statue at the front of the stadium was 3D laser scanned to create a triangulated 3D mesh model in .fbx file format for the animation/CGI Benefits • 3D laser scanning is a fast and accurate way to digitize real-world objects for use in computer-aided design (CAD) and mixed reality • 3D models are created in our corporate office by experienced engineers and CAD technicians • The Famous Group was able to create a mixed reality experience that included an enormous virtual panther skulking through the stadium and onto the Jumbotron, delighting the 70,000 fans in attendance

Field verification to prefabricate ACM panels

Our client was installing ACM panels to the canopy of a newly constructed airport terminal. The construction plans did not match the existing conditions at the site. A deviation could cause a major issue. The installation process needed to be precisely planned to avoid rework.

The construction plans did not match the existing conditions at the site. The installation process needed to be precisely planned to avoid rework • The shape of the canopy was complicated and stood 65 feet in the air. The client needed field verification and a plan to expedite proper installation of the panels • Installers were working overhead in a lift; there was no room for trial and error Solution • The Project Manager conducted a site walk to devise a plan for the client • The canopy and curtain wall of the airport terminal were 3D laser scanned to capture precise as-built data and generate a 3D model and 2D drawings to facilitate ACM panel installation • 22" x 34" 2D CAD drawings were created with the panel layout for the client to take to the field. This allowed each panel to be labeled with a custom number, cut and shim points Benefits • Laser scanning obtained exact measurements for the client and took away any guesswork from this project • To circumvent the active construction site, the Project Manager scanned the site at night to eliminate movement and trades working • The client was able to fabricate components offsite and plan a flawless installation
