CASE STUDY: 3D Scan Bank Building in Las Vegas, NV.
Arrival 3D are tasked with the 3D Scanning of a Bank Building for the purposes of providing 2D Elevation’s (.dwg) documentation to facilitate development of new Steel Cladding.
What Was Scanned
3D Laser Scanning in Reno, NV: Our client, a leader in Metal Cladding for commercial properties nationally, tasked Arrival 3D with the 3D Data Capture of a new bank building in Las Vegas. In order to achieve the highly toleranced, perfect visual appearance expected, our clients understand it’s first necessary to accurately document “As built” conditions.
The starting point is to document the structure via 3D Laser Scan Data, which is where Arrival 3D bring value.
The resulting Scan Data, a “point cloud” comprising millions of points of data, can be utilized as is for both measurement and spatial planning, or the data can form the basis of an accurate, geometric CAD model. Arrival 3D routinely provide to clients both point cloud, and Revit CAD models.
These tanks were scanned from multiple positions around the perimeter, providing a detailed 360′ point cloud suited to dimensionally accurate spacial planning.
The Arrival 3D data collection process takes only a few hours onsite, the equipment is compact and clean, and we require only easy access to the property. You will see the Leica RTC360 positioned in one of multiple positions in the accompanying image.

Las Vegas, NV.
The accuracy required for Steel Cladding can be achieved only with 3D Scan Data as a basis for development.
Scanner(s) Used
Arrival 3D have a large inventory of 3D Scanners suited to a variety of tasks. Our most recent acquisitions, and currently our favored multi-tasking 3D Scanners, are our Leica RTC360’s. Arrival 3D now have several Leica RTC-360’s positioned strategically around the United States. We use the RTC360’s frequently due to their great versatility; portable size, long range accuracy and rapid scanning capability.
- Speed: <2 mins for complete full dome scan and spherical HDR image at 6mm @ 10 m resolution.
- Accuracy: 3D Point Accuracy 1.9 mm @ 10 m, 2.9 mm @ 20 m, 5.3 mm @ 40 m.
- Range: Min. 0.5 - up to 130 m
- Highly Portable: Compact & weighing in at 5.5kg (11.7lbs), the Leica RTC360 scanner’s portable design and collapsible tripod mean we can reach our clients quickly and efficiently.
- In Use: Once on site, an easy-to-use interface enables rapid set up per 3D Scan requirements. We can scan in low thru high Resolution, Color or Greyscale and can enable Tilt control.
- Real Time Registration: Automatic point cloud alignment based on real time tracking of scanner movement between setups based on Visual Inertial System (VIS).
- Final Registration: For the RTC360 Arrival 3D utilize Leica Cyclone REGISTER 360 software to integrate 3D pointclouds. Output files can be created in multiple formats for seamless integration into software products such as Autodesk Revit, Dassault SolidWorks and many others.

Deliverables
Our client chose, in this case, to receive 2D Elevation drawings (.dwg) of the facades of the building. In order to facilitate these deliverables, we first 3D Laser Scan the subject. The resulting registered “Point Cloud” comprises the combined points from several scans into a single, registered 3D file. The data represents a full 3D image of the subject which can be navigated through, which can provide measurements and angles, and which includes the images created at each of the scan positions, referred to as “Viewing Spheres”.
- A point cloud is a set of data points in space. The points may represent a 3D shape or object. Each point position has Cartesian coordinates (X, Y, Z).
- Point clouds are used for many purposes, including to create 3D CAD models for manufactured parts, for metrology and quality inspection, and for a multitude of visualization, animation, rendering and mass customization applications.

Added Value
Arrival 3D have in the past been called upon to scan architectural projects where the client had attempted, unsuccessfully, to take manual measurements of the area they have intended to change. Later, having spent a great deal of time & money, and having constructed sub-assemblies that won’t fit, Arrival 3D have been called upon to 3D Scan and document the areas in question. Rarely do existing architectural structures have existing, or accurate, blueprints. Furthermore, existing structures can subtly change dimensionally over time from their built condition, for countless reasons.
Arrival 3D are equipped and able to rapidly document existing conditions, provide that data to our clients in a multitude of formats, and ultimately save our clients time, trouble and valuable funding in documenting the reality of projects presented to us. The peace of mind that is inherent with a digital representation of a project is priceless and the ability to share this accurate data with the entire team instantly, and often remotely, is one of the wonderful benefits that these technologies allow us today.
