A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations. Our client was an architecture, planning and interior design firm specializing in commercial, institutional and academic design.

A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations.

Location: Denver, Colorado Task: A Denver Catholic church and school constructed in the 1950’s requested 3D laser scanning of their 56,000 sq ft three-building campus to plan for renovations. Our client was an architecture, planning and interior design firm specializing in commercial, institutional and academic design. Problem: Construction documents existed from the original build, but the client was unsure if they were up to date. Each building required a different scanning scope. The church and parish hall required complete exterior and interior documentation, while the school required only exterior documentation. The church required new design drawings and cost estimates from the firm before proceeding with renovations. Solution: In one day on-site, a GPRS/TruePoint Project Manager completed 359 scans with the Leica P50 ScanStation and the RTC360 laser scanner. The client required point cloud files, 2D CAD drawings, a 3D Revit model, and TruViews to understand the existing conditions of the buildings on campus. 2D CAD exterior elevations and floor plans of the church; and exterior elevations of the school were created for this project. An LOD 200 Revit 2021 3D model of the church was delivered with architectural/structural details, including columns, beams, walls, floors, ceilings, doors, windows, stairs, roof, pews, lectern, and alter. An LOD 200 Revit model was delivered of the school exterior. Benefits: Renovations are not new to this campus; they recently added an outdoor learning lab and eucharistic adoration chapel. They understand the value of accurate as-built data. The firm wanted to keep the historic craftsmanship of the church but provide modern updates. A quality point cloud created a reliable as-built BIM model of existing conditions with ¼ inch accuracy tolerance.

3D Laser Scanning

For oil tank replacement, the true shape and condition of the tank can be critical for ensuring that the new design fits the existing conditions; reducing costly delays or rework.

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.

3D laser scanning by GPRS for an oil tank replacement.

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. GPRS Intelligently Visualizes The Built World® for customers nationwide. What can we help you visualize? For 3D laser scanning services in Kansas, call GPRS.

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.
