A GPRS Case Study

3D Laser Scanning Building Façade and Awning

3D Laser Scanning Building Façade and Awning

Highlights

THE BOTTOM LINE

With the possession of an as-built, field-verified 3D model of the façade and awning, our client can confidently design and fabricate the necessary custom panels for their project. All guesswork is eliminated from the equation and the client can rely solely on the accurate measurements collected by Leica 3D laser scanners.

Deliverables

The final deliverables for this project consisted of an intensity map point cloud (.PTG format), Leica JetStream Viewer files (.LGS file), and a 3D model delivered in a .STP file format. All of which were mailed on a 1TB hard drive sent directly to the client’s office in Pennsylvania.

Task

GPRS’ task on this project was to laser scan and 3D model a façade for a building addition under construction at an airport. After receiving the 3D model, the client requested a second mobilization to 3D laser scan and model the building’s awning.

PROBLEM

GPRS’ client was fabricating and installing custom architectural panels for the building addition. The panels needed to fit perfectly and attach seamlessly with the already built substructure and window arrangement. The size (25+ ft tall) and intricate detail of these panels made them very difficult to accurately measure using traditional measurement techniques.

For the second mobilization, awnings would also have to be made to adhere to the unique geometry of the awnings already in place at the airport.

 

Solution

The final deliverables for this project consisted of an intensity map point cloud (.PTG format), Leica JetStream Viewer files (.LGSfile), and a 3D model delivered in a .STP file format. All of which were mailed on a 1TB hard drive sent directly to the client’s office in Pennsylvania.

GPRS was able to quickly mobilize and scan the 17,000 sq. foot façade in one day. 59 laser scans were completed with the Leica P50 and P40 ScanStations from both the ground level and the elevated roadway that leads to the passenger drop-off zone.

For the second mobilization, GPRS completed 23 scans with the Leica P40 ScanStation to gather precise data of the awning.

Using industry standard registration methods, the scans from each dataset were seamlessly tied together to provide comprehensive detail of the façade and awning from all necessary vantage points.

 

Benefits

With the possession of an as-built, field-verified 3D model of the façade and awning, our client can confidently design and fabricate the necessary custom panels for their project. The client can reference the models during installation to troubleshoot on-site issues that may arise. Essentially, all guesswork is eliminated from the equation and the client can rely solely on the accurate measurements collected by Leica 3D laser scanners.
