3D Laser Scanning Services in Mississippi

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

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.

In just one day on site, GPRS was able to capture the entire existing condition of the facility, even in dense pipe runs and hard-to-reach spaces, with 2-4mm accuracy to provide the client with an accurate 3D BIM model for planning, fabrication, and clash detection

An engineering firm needed to have existing conditions of a power plant documented and modeled to plan for renovations.

An engineering firm needed to have existing conditions of a power plant documented and modeled to plan for renovations.

Problem • The client needed to accurately document the existing conditions of the plant without interruptions to the power supply • Many of the pipe runs were dense and impossible to accurately measure by hand • The client required 2-4 mm accuracy of dense piping and pipe runs throughout the facility • The client needed to guarantee that installations complied with safety regulations Solution • In one day on site, GPRS' Project Manager used the Leica RTC360 laser scanner to capture 150 laser scans, documenting existing conditions of the facility • Many of the pipe runs were dense and impossible to accurately measure by hand • GPRS generated a 3D BIM model for use in CAD software, including all civil, structural, electrical, and mechanical features, piping, and conduit 1" and larger Benefits • Due to the vast space and density of the 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 • The point cloud data from laser scanning was used by CAD technicians to create an intelligent 3D BIM model for planning, fabrication and clash detection • Verified measurements and virtual planning guarantee installations will comply with safety regulations • Using virtual 3D models, the firm can plan and model future developments to manage the facility without having to re-enter the site

3D Laser Scanning

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
