The cost avoidance impact of the integrated scan-to-BIM workflow saved the project an estimated 5% of the total contract amount, a savings of approximately $1,500,000.

GPRS provided 3D laser scanning and modeling services for a 15-story structure in the greater Cincinnati, Ohio area. This included 8 floors of commercial space, 2 stories of retail, 5 levels of parking garage, as well as the exterior façade and roof surface. The GPRS Project Manager captured over 1.54 million square-feet of space, and in-house engineers created a custom Revit model based on the point cloud of the existing conditions. Once construction was complete, this project received the 2017 Build Ohio Award for New Construction Over $30 million.

3D Laser Scanning

With the millions of data points collected, GPRS’ Mapping & Modeling team could create an accurate LOD 200 Revit 2021 BIM model of this processing facility.

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.

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.

3D Laser Scanning

292 individual interior and exterior LiDAR scans were completed in a single day, capturing existing conditions including all historical features, all without disrupting the historic site's operations or impacting its valuable contents so that a renovation could be designed and planned without requiring time consuming hand-measurements.

3D laser scanning a historic Massachusetts library to create a 3D BIM model.

GPRS 3D laser scanned a historic library in Amherst, Massachusetts and created an LOD 300 Revit model for the architect. The interior and exterior of the library was 3D scanned, this was an estimated 47,000 sq. ft. of space with 4 levels.

Built in 1919: there were no existing as-built details availableIt was likely that the existing condition of the building included unsquared architectural features The library’s historic features had to be preserved and intact during and post-renovation The library needed to remain open to patrons and conduct regular operations while visualization was completedPaintings of Emily Dickinson and Robert Frost, plus local historical exhibits, were contained in a gallery on site that needed to remain untouched Laser scanning was executed on Patriot’s Day, a Massachusetts state holiday. The library was closed so all scans could be completed without disrupting operations292 laser scans were completed of the interior and exterior of the library; approximately 47,000 sq. ft. of space spanning four levels An intensity map point cloud and 3D BIM model were delivered to the client, giving them accurate data of the current as-built conditions 3D scanning provided updated floor plans and captured existing conditions via a 3D BIM model to speed redesign and planningArchitects, designers, and contractors could access and utilize the BIM model and 3D laser scanning data at any stage of the restoration process for reference3D laser scanning is non-contact; scanning from a distance minimized the risk of damaging historical art work and exhibits and was completed in a single day on site
