Existing Conditions, a GPRS Company, provided 3D laser scanning and modeling services to support the completion of an award-winning expansion to Boston Logan International Airport.

• AECOM, Suffolk Construction, and Luis Vidal + Architects needed accurate existing conditions documentation of multiple existing spaces inside the airport • The contractor also needed precise as-built documentation of the new construction prior to sheetrock installation, to comply with Massport (Massachusetts Port Authority) regulations • Many of the spaces that needed to be scanned were congested with MEP runs and other infrastructure • All work had to be completed while the airport was in operation SOLUTION • Existing Conditions utilized multiple 3D laser scanners, including the small and nimble Leica BLK360 laser scanner, to capture the required data • The contractor was so impressed with our work on the initial project that they asked us back to scan additional spaces • 3D Revit models were created using the scan data to allow for remote planning BENEFITS • The accurate and comprehensive as-built data provided Boston Logan with a detailed record of the building’s current state before renovations were completed, and of the new construction • Highly detailed, accurate digital measurements assisted with the safe and successful expansion of the structure • The client and their subcontractors could reference this data as they completed their work, and it will be preserved for future O&M purposes

Accurate 3D BIM modeling allowed the developer and two architectural firms to collaborate and more easily communicate with their general contractor, which saved time and money on a massive adaptive reuse project

$30 Million Hotel & Parking Garage Adaptive Reuse Project Required Accurate 3D Visualizations

Laser scanning to create a 3D BIM model of a 15-story hotel and adjacent parking garage for building redevelopment. The developer requested a 3D BIM model that accurately captured existing conditions in a cloud-based platform so they could document, view, and plan for structural renovationsWith a 3D model, the architectural team was able to view the existing conditions at the onset of the project. The model was then updated as construction progressed to keep all parties on the same page throughout the projectThe 3D model allowed the firms to communicate construction requirements to the general contractor to avoid miscommunications, reworks, delays, and cost overruns

$30 million-budgeted adaptive reuse project converting 130,000 sq. ft. hotel property into 100 residential units Most floors of the building were completely gutted: only the exterior envelope and interior circulation core remained intact With two architectural firms, a developer, and a G.C. meant that this project involved many professionals a lot of planning before breaking ground The developer requested a 3D BIM model that accurately captured existing conditions in a cloud-based platform so they could document, view, and plan for structural renovations With a 3D model, the architectural team was able to view the existing conditions at the onset of the project. The model was then updated as construction progressed to keep all parties on the same page throughout the project The 3D model allowed the firms to communicate construction requirements to the general contractor to avoid miscommunications, reworks, delays, and cost overruns The 3D model allowed the architectural team to troubleshoot the restoration and adaptation while keeping historic elements intact to preserve the building's characterDelivering the 3D BIM model in a digital format with the ability to update and edit, streamlined communication and collaboration across a large and diverse project team to bring the project in with fewer clashes, reworks, and mistakes, saving time and money

3D Laser Scanning

Our client required a high-detail 3D BIM model to accurately visualize, design, modify, and manage the update of a heat exchanger within a Wastewater Treatment facility, enabling efficient updates and modifications without the need for extensive on-site measurements or manual drafting.

GPRS was called to 3D laser scan the Southerly Wastewater Treatment Plant and render an LOD 300 BIM model of the three-level heat exchanger for ABC Piping Co. to update one of the systems.

GPRS 3D laser scanned the Southerly Wastewater Treatment Plant to develop a LOD 300 3D BIM model for ABC Piping Co. to update one of the heat exchangers at the facility.

Highlights THE BOTTOM LINE Our client required a high-detail 3D BIM model to accurately visualize, design, modify, and manage the update of a heat exchanger within a Wastewater Treatment facility, enabling efficient updates and modifications without the need for extensive on-site measurements or manual drafting. INDUSTRY Water Treatment Plant & Wastewater Treatment Plant SERVICE 3D Laser Scanning; Mapping & Modeling LOCATION Cleveland, Ohio PM Insight The Leica RTC360 can generate 3D point clouds in less than 2 minutes, delivering our clients quick data visualization for project planning. The Leica RTC360 scans in color, which is useful when you need a true representation of a site in color detail. Deliverables LOD 300 3D BIM Model Task GPRS was called to 3D laser scan the Southerly Wastewater Treatment Plant and render an LOD 300 BIM model of the three-level heat exchanger for ABC Piping Co. to update one of the systems. PROBLEM Our client desired to upgrade the heat exchanger to reduce maintenance, energy consumption, and overall operational expenses in the long term. To properly design, prefabricate, and install system updates, ABC Piping Co. required a detailed 3D BIM model of the current mechanical and piping system, including pipe sizes, materials, and routing. Solution GPRS partnered with ABC Piping Co. to 3D laser scan and model the heat exchanger at the Southerly Wastewater Treatment Plant for upgrades. GPRS utilized the Leica RTC360 laser scanner to capture as-built conditions from 3 different floors around the existing heat exchangers. 108 laser scans were taken with the RTC360 from different locations to capture the intricate details of this very dense mechanical facility. The 3D BIM model provideed a detailed and accurate representation of the existing heat exchangers within the facility, enabling engineers and designers to clearly understand the spatial relationships, constraints, and interdependencies between various components. Benefits 3D laser scanning captured precise layout, dimensions, and locations of the existing architectural, structural, MEP, FP, and HVAC system elements for this facility in a point cloud. The GPRS Mapping & Modeling team transformed point cloud data into an intelligent 3D BIM model to aid system engineering. A 3D BIM model saved in a shared environment allowed all disciplines to work together to identify and resolve clashes before the system integration begins, ensuring a smooth retrofit with minimal rework. ‍
